Returning to the attendance clerk's office again, Fang Hanmin exchanged pleasantries with Xiao Min as usual. Perhaps he didn't notice that Xiao Min was more polite and less casual with him.
In the past, whether it was the first time that Fang Hanmin worked in the attendance officer's office or the second time that she worked in the same office as Xiao Min, she not only asked Fang Hanmin about what he was doing, but also showed great enthusiasm and care for Fang Hanmin.
When I met Fang Hanmin in the office this time, Xiao Min handed him the office supplies, only poured him a glass of water and put it on the table politely. He didn't ask about work at all, and just immersed himself in doing his own thing.
Fang Hanmin is introverted. He has never really been in love and is not sensitive to the feelings between men and women at all. Xiao Min's emotional changes did not attract any attention from him.
Although Xiao Min didn't know what was going to happen, the factory leader summoned Fang Hanmin to a meeting, which showed that he had received the attention of his superiors. Of course, Xiao Min was happy for Fang Hanmin, because she had to take into account the opposition of her parents and family, so she could only treat Fang Hanmin's The feelings were hidden deep in his heart, and Fang Hanmin had no idea about it. Both parties acted as if nothing had happened, which was just conducive to Fang Hanmin devoting all his energy to work.
There is a lot of work to be done in the upcoming test. According to the plan, Fang Hanmin must first formulate the process flow of steam distillation. After doing some calculations, he spent a day drawing a sketch of the process flow, and then proposed an equipment list and material details. , took these technical materials to the workshop office, and Fang Hanmin wanted to discuss with the two workshop leaders how to maximize the use of existing equipment.
Because Factory Director Yuan has clearly instructed that the leaders of the second workshop must fully cooperate with Fang Hanmin's work. In the past few days, technician Lao Wu, like the workshop director, has been staying in the office, ready to provide assistance to Fang Hanmin's work at any time.
When Fang Hanmin came to the workshop office, Lao Wu did not deliberately avoid it like before. He greeted the two leaders, "Director Yang and Wu Gong, I am here to report to you."
"We don't understand your job, what are you reporting to? Hanmin, sit down, just tell us what you need us to do." For Fang Hanmin, Lao Yang seemed more enthusiastic than before.
"Yes, if you have any questions, you can just tell me directly. There is no need to report." This is the first time that Old Wu can express such an open-minded attitude.
Fang Hanmin sat down on the bench next to the desks of the two leaders and took out the prepared equipment details and material list. "These are the equipment needed for steam distillation. In order to maximize the use of the existing equipment in the second workshop, I put The process flow was compared with the existing equipment, and it was found that the equipment in the sixth unit is most similar to the process conditions of steam distillation." After speaking, Fang Hanmin handed several forms in hand to Lao Yang and Lao Wu, and asked them to review them. .
The two leaders unanimously refused, "We don't understand the steam distillation process. If you think the equipment of the sixth unit is the most suitable, then use the equipment of the sixth unit. What adjustments need to be made to the equipment and process pipelines? As long as you give Once we come up with a specific adjustment plan, we will arrange manpower to start working.”
Fang Hanmin knew that the two workshop leaders did not have the ability to intervene in technical issues, but he still took the initiative to report to them. First, out of respect for them, and in addition, he asked them to assist him in his work, so that the two leaders, especially the workshop Technician Lao Wu is more receptive.
Later, Fang Hanmin handed over the adjustment plan for the equipment and pipelines of the sixth unit to the workshop technician Lao Wu, and discussed with the two leaders the settlement method of the wastewater after desolvation and deodorization.
Centrifugal sedimentation has high efficiency, good sedimentation effect, and is easy to operate, but it requires special equipment and consumes a lot of power. Graded settlement requires the construction of multiple settlement tanks, covers a wide area, requires a large amount of civil construction, and is cumbersome to operate. The advantage is that it requires less investment and can be implemented immediately.
Fang Hanmin compared the advantages and disadvantages of the two methods and asked the two leaders to weigh and choose. Lao Yang chose the graded settlement method without hesitation, “Isn’t it just a matter of digging a few settlement tanks and doing some anti-leakage treatment? At most, adding a rainproof shed is faster than purchasing special centrifugal equipment. The key is that graded settlement not only saves investment, but also consumes basically no electricity in actual operation.”
Lao Wu seems to have a far-sighted vision, "Grade sedimentation seems to have some advantages at present, but it is not conducive to continuous operation and automated control. I think the development trend is centrifugal sedimentation."
"The problem now is to save time and money. Whichever method is faster and saves money, choose whichever method. As for continuity and automation, let's solve the current urgent needs first." Lao Yang is the workshop director. The idea is more realistic.
Although they did not say it explicitly, the two workshop leaders also knew that they needed to assist in completing the tasks. In front of Fang Hanmin, Lao Yang and Lao Wu divided the work. Lao Wu was responsible for organizing the adjustment and construction of the equipment and pipelines in the sixth unit. Lao Yang Responsible for the construction of wastewater settling tanks.
On the day when the factory leaders convened a meeting, both workshop leaders were present. There was no need for Fang Hanmin to emphasize that Lao Yang and Lao Wu also knew the urgency of the work. Therefore, after the tasks were clear, they did not dare to slack off in the slightest.
Perhaps he was aware of the seriousness of the matter, or was afraid that the factory leaders would come to the workshop to check the work progress. In short, Lao Wu was very attentive in assisting Fang Hanmin in his work this time. He spent all day staring at the equipment construction site of the sixth unit. When there was not enough manpower, he He even took matters into his own hands, rolled up his sleeves and worked with the employees.
The role of leadership is obvious. Under the leadership of Lao Wu, it only took five days to complete the equipment and pipeline adjustment of the sixth unit. After another day of debugging, Fang Hanmin passed the inspection and started on the seventh day. Conduct a steam distillation test of wastewater.
In fact, this kind of test is only for the leaders to see, because the leaders are not at ease. Only through tests that prove that Fang Hanmin's technical solution is indeed feasible can the leaders' concerns be completely dispelled.
For Fang Hanmin, such an experiment cannot be called a scientific experiment at all, because in his previous life, when he graduated from university, the Huakang Pharmaceutical Company where he interned used this method to treat wastewater generated by the reduction of iron powder. Fang Hanmin He has long been familiar with this craft, and now he just picked it up and used it. He found the idea of experimenting funny.
Therefore, the success of the first trial run made other people think it was incredible, but Fang Hanmin was very calm in his heart. He believed that this was just a copycat technology application, and it was not worth making a fuss about.
The key to measuring the success of wastewater treatment is the content of various organic matter in the treated wastewater. Only those harmful components that meet the national discharge standards can be considered effective treatment. Otherwise, no matter what method is used, the treatment process will be ineffective.
The test results show that through steam distillation, the total content of aromatic compounds in the wastewater is lower than the minimum value stipulated by the state, and the content of other organic matter is also within the standard range, proving that Fang Hanmin's steam distillation process is effective in reducing iron powder wastewater The processing was successful.
After three consecutive days of inspection, through regular and anytime sampling, the test results proved that the wastewater after steam distillation not only had stable indicators, but also fully complied with the emission standards.
The news spread like wildfire, and several factory leaders also learned about it one after another. The top leader, Lao Yuan, Deputy Factory Director Wang in charge of production, and other deputy factory directors were very happy. They believed that there was finally hope of completely eradicating the wastewater pollution problem in the second workshop. However, Chief Engineer Lao Xia disagreed. He did not believe that Fang Hanmin could complete this test in industrial equipment, let alone that Fang Hanmin could complete such a major test within ten days!
If the steam distillation process did not consume other raw materials except for using a little water vapor during the operation, Lao Xia would not have agreed to let Fang Hanmin use the workshop equipment to conduct experiments at the meeting that day. He believed that even if Director Yuan’s concession was There are also great risks in the middle plan. If additional new raw materials need to be added, can Fang Hanmin be held responsible if the test fails? As the chief engineer of Red Star Pharmaceutical Factory, Lao Xia felt that he had the right to prevent this risky behavior.
Hearing that Fang Hanmin had completed a steam distillation experiment in the workshop, Lao Xia was the first to not believe it. He shook his head like a rattle, "No way, this kind of large-scale experiment is not as simple as a sugar whistle!"
Lao Xia's mentality is completely understandable. At the meeting, Factory Director Yuan directed us to separate operations. Lao Xia organized technicians to conduct small experiments in the laboratory to verify Fang Hanmin's wastewater treatment process. Fang Hanmin directly used industrial equipment in the second workshop. test.
Lao Xia followed the old work rhythm and method and started working step by step from the organization of personnel, the purchase of instruments and equipment and related reagents. Ten days have passed and he has just organized the personnel and left some of the instruments and equipment purchased by the supply department. the arrival.
On the other side, Fang Hanmin did not follow the routine. He acted vigorously and resolutely. From determining the process flow and selecting and adjusting the equipment to obtaining stable test results, it only took ten days!
While the leaders of other factories were happy, the chief engineer Lao Xia was not good-looking. But the test results were there, and Fang Hanmin could not block the news of the successful test just to save Mr. Xia's face.
In the chief engineer's office, Lao Xia's assistant told him that the news about Fang Hanmin's successful experiment was true. Lao Xia lowered his head and said nothing. After a while, he suddenly stood up and said, "Come on, come with me to see their experiment in person." .”
When the assistant accompanied Lao Xia to the site of the sixth operating unit of the second workshop, a set of water vapor distillation industrial equipment was in operation. Lao Xia and the assistant walked around the equipment several times, and then climbed to another one seven or eight meters high. The operating platform was carefully inspected. The assistant was an engineer and could understand a little bit about the operation of the production equipment. He sighed quietly next to Lao Xia, "This is not an experiment! This is nothing like normal production. Any difference.”
Lao Xia ignored what his assistant said. He asked the operator on site: "Who is in charge here? Isn't Xiaofang here?"
"We have a temporary squad leader in charge here. Who are you talking about, Fang Hanmin? He came here half an hour ago, maybe he went back to the office."
Lao Xia didn't say anything else. After leaving the operation site of the sixth unit, he and his assistant did not go to Fang Hanmin, but went to the laboratory of the second workshop. Although several laboratory technicians were not familiar with them, they knew that the old man was Red Star. Chief Engineer of the Pharmaceutical Factory, "What is he doing here?"
When several laboratory technicians were puzzled, Lao Xia asked them: "Have any samples been taken for testing of the treated wastewater?"
The older laboratory technician explained to Lao Xia that according to Fang Hanmin's arrangement, the treated wastewater must be sampled and tested every two hours. In order to meet the process requirements of the continuous operation of the sixth unit unit, during the test period, the laboratory deployed dedicated personnel. Follow up, regardless of day shift or night shift, we must ensure that the treated wastewater is tested promptly and accurately.
