When he was thinking about what else to write, there was a noise outside. It turned out that Wu Nanhai from the agricultural team and He Ping, who was sent by Shi Niaoren to disinfect the toilets, had quarreled and came all the way here to ask for an explanation. [Full text reading] Although He Ping was an employee of a large state-owned pharmaceutical factory before time travel, he was actually doing maintenance work on equipment and instruments and did not understand medicine and pharmacology. The health team wanted him here because of his wife Zhao Yanmei is a technician in the mold seed laboratory of a pharmaceutical factory - Shi Niaoren is planning to join the pharmaceutical factory project in the future, Zhao Yanmei must be retained first, and of course to keep a wife, she must also keep her husband.
He Ping, who has a rectangular face, glasses, and a scholarly look, simply became a clerk for the health team, doing odd jobs and running errands. Why did you get into a fight with someone for no reason?
When I went out, I saw the fat man Wu Nanhai grabbing He Ping with an angry look on his face, while He Ping looked aggrieved and was holding a nylon bag containing lime in his hand.
"Did you ask him to spread lime?" When Wu Nanhai saw the leader coming out, he focused his firepower on Shi Niaoren.
"What? Is there a problem? Our health team is disinfecting the toilets."
"Do you understand chemistry?" Wu Nanhai pointed to lime, "Farm manure such as manure is a nitrogenous fertilizer and cannot be mixed with alkaline fertilizers such as plant ash and lime. The result of mixing will be neutralization failure. You are so powerful What's the use of the excrement in the toilet if you sprinkle lime on it?!"
Shi Niaoren's face was very ugly. After all, he was also a doctor studying in the United States. He was called a beast in medicine. He had performed surgery in the United States and had been prevented from epidemics in the imperial capital. Wouldn't it be a huge loss of face to question an undergraduate from the No. 1 Agricultural University if he knew chemistry? . But then I thought about it. As the person in charge of agriculture, Wu Nanhai is also one of the executive committee members. Agriculture is an industry that the executive committee is ready to work on quickly. In the future, many logistical support matters may have to rely on the agricultural department—himself. He was the person in charge of the health center. The two persons in charge had a falling out face to face and they couldn't even move around in the future. Then he calmed down a little and suppressed his anger. He really didn't think about the problem of fertilizer efficiency. Using lime to disinfect the toilet is the simplest and most common disinfection method. When disposing of the excreta of infectious patients, disinfection with lime is almost a necessary procedure.
"This is our negligence." Shi Niaoren hurriedly greeted Wu Nanhai and coaxed Wu Nanhai away with kind words. Xiao He looked unhappy - he was being criticized for not performing the leadership task.
"Isn't it just shit? Just give him a few more dips!"
"We are also learning through practice." Doctor Shi reassured his soldiers, "Wu Nanhai needs fertilizer to engage in agriculture - crops and flowers." He glanced at the lime bag and saw that not much was used. The lime was obtained from the construction engineering department - he couldn't bear to part with the bleaching powder - and was going to be used to treat drinking water.
Lime cannot be used, and bleaching powder is reluctant to part, so the harmless treatment of feces has to be thought of separately. Shi Niaoren's main field is infectious diseases, and he is no stranger to epidemic prevention. He knows that there are many kinds of harmless treatment of general excrement. Lime, bleaching powder, etc. are quick-acting. If not, the simplest way is to store it in a sealed container. , but there must be a third-level septic tank--or at worst, a septic tank... Do you want some natural plants? He remembered that the book he had read said that some natural wild plants could also be used instead. The problem is that he can't remember which plants they are, and he has never studied Chinese medicine, so even if he knows the names, he may not recognize them.
Just as he was thinking about whether he should make a report and ask where there are talents in traditional Chinese medicine, Tian Jiujiu came in again and asked the health team what kind of water treatment method they planned to use so that they could come up with a water supply plan for construction as soon as possible.
"It's really one out and one in." Shi Niaoren murmured to himself.
"What?" Tian Jiujiu was confused.
"Nothing, I'll come to the construction site right away."
The water supply system is under the direct control of the health team. The shallow groundwater near Bopu has high salt content and is not suitable for drinking water. They have no conditions to exploit the deep water. The only feasible solution is to pump water from the Wenlan River.
As a water supply, the most ideal is spring water or deep groundwater. Rivers like the Wenlan River have a large flow and have relatively good self-purification capabilities, and they are also usable water sources. However, this is a river delta area, and the water quality is generally poor. If there is greater pollution, water treatment will be more complicated.
Shi Niaoren tested the water depth and flow rate, and extracted a 25m1 water sample from 50 centimeters below the water surface. He did not have any testing equipment, so he had to use the simplest visual inspection and nose smelling method.
Seeing the results, he shook his head repeatedly. I thought that considering the pollution level in the 17th century, the river water should be very clean. The fact is that although there is little sediment in the water, there is a lot of algae. It shows that the organic matter content in the water is too rich, which is certainly not surprising in modern time and space - it is all caused by chemical fertilizers, but there were no chemical fertilizers in the Ming Dynasty. Such a high organic matter content only shows that the middle and upper reaches of the river are agricultural areas or residential areas in Da.
Of course, it is not impossible to use this water. According to Ji Niao Ren's observation, this water is still Category 3 water according to modern standards - the water intakes of some modern city water plants cannot meet this standard.
If such water quality is to be used as drinking water, it is necessary to use a set of quite complicated sedimentation, filtration, and disinfection processes. No matter which water supply mode is adopted, sedimentation tanks, filter wells, disinfection tanks, and water channels are required... which is in great demand for building materials. Isn’t this a fantasy for the engineering team?
Considering the bad infectious disease situation in ancient times, there is a high possibility that water bodies contain cholera and typhoid bacteria. Shi Niaoren thought over and over again and thought it would be better not to use river water until there was no condition to establish water treatment facilities.
"It's better to send fresh water from the boat to the shore." He sighed and went directly to Ma Qianxu to report.
Ma Qianzhu didn't know much about how to solve the fresh water problem on the ship, so he called Mond and asked him.
"There is some water on the ship, but it can't hold it for long." Mond explained: The general hull design has at least two fresh water tanks. One storage drinking water is the fresh water connected to the shore after entering the port; the other storage daily water is the distilled water condensed from the cooling water of the main engine. This kind of soft water obtained by desalination of sea water is usually used for sanitary washing and is generally not drunk. Sometimes drinking water is not enough.
Because Fengcheng was designed as an ocean liner, it has four fresh water tanks and a considerable water storage capacity. However, the original design was to provide a crew of forty or fifty, and now there are nearly 600 people, which is a bit difficult. The amount of newly generated distilled water when the auxiliary engine is running is limited, and it cannot be supplied on a large scale for a long time.
"Use auxiliary engines to provide fresh water!" After listening to his report, Ma Qianzhu frowned, "This is exchanging diesel for water!" He felt a little regretful, "There is no diesel flowing in the river."
Shi Niaoren knew that he was worried about the oil on the ship, but he knew that in Lingao, intestinal infectious diseases such as cholera, typhoid fever, and paratyphoid fever were very widespread in history. Until the 1970s and 1980s, cholera and typhoid fever were still rare. Explosive scale. Although the people who traveled through time are now vaccinated thanks to modern medicine, there is no guarantee that they will be fine - even if they don't get infectious diseases, acute enteritis is enough for them to suffer.
After expounding the pros and cons, Ma Qianzhu had no choice but to accept the suggestion. In order to save water as much as possible, the headquarters decided after discussion: to set up a centralized water supply station on the shore, lay water hoses with floating barrel lines, and lead the fresh water on the ship to a 2-ton capacity stainless steel water tower in the living area - only For drinking and washing.
"As for taking a bath or something, let's just get over it for the time being." Ma Qianzhu knew that this limited supply of fresh water policy would definitely attract countless curses to him, but he had no choice but to do so. He sat down and drafted a document, which was sent by oa. "Building materials" he wrote on his notepad. Many things today were restricted by this building material. He must try to solve them during the meeting in the evening.
The dusk is getting thicker, and the day of D-Day is about to pass. As the order to "end work" came from the walkie-talkie, the travelers who had been working at the outer construction site for a day gathered in twos and threes towards the camp.
The men of the logging team were returning from the mangroves while talking. Carrying tools on their shoulders, although their bodies were exhausted, everyone felt warm emotions in their hearts, and their feelings for each other seemed to have improved a lot.
The tide is receding, and the water is washing over the large and small rocks in the bay. Looking from a distance, the outline of Lingaojiao appears on the western skyline. The blood-red sunset slowly sank among the scattered clouds. The sky and sea in Bobu Bay blend into each other and shine brightly. The sea water turned golden red as if it was burned by fire.
The fleet of traversers was moored in the bay one after another, and the dark shadows of the ships were inlaid with a radiant golden edge by the sunset. These ordinary cargo ships and fishing boats, to them at this moment, were like the ones in Pascual Bay. The Imperial fleet is generally magnificent.
This magnificent scenery made them intoxicated, and the inexplicable excitement made them speechless. Not only them, but also those who came back from other peripheral construction sites also slowed down and looked at this gorgeous and magnificent scene.
"Everyone, let's go quickly, it's getting dark." The military team member at the back greeted them while checking to see if there were any stragglers who had fallen behind. According to the plan, they should go last. Make sure no one is outside the camp after dark.
"Guntower!" someone shouted, and everyone looked in the direction of the camp. An earthen fence had been built around the standing beacon tower, and a barbed wire fence had been erected on it. At first glance, it looked like a Japanese guntower in an old movie.
After a day of construction, the entire camp began to take shape. With the beacon tower and the inspection department's house as the core, the entire camp was in the shape of an irregular pentagon. A trench 5 meters wide and 2 meters deep was excavated on the outside, which was filled with water from the Wenlan River. The inside of the trench was built 1 meter higher than the outside, and a barbed wire fence was laid over it. The barbed wire is 2 meters high, fixed crosswise with wooden stakes, and buried very firmly. The lower part of the barbed wire is also laid with a bellows type barbed wire. After the barbed wire fence, the soil from the trench was piled and rammed into a long rampart, and trenches were dug on top. In addition, six 8-meter-high wooden structure sentry towers were built on the long base.
At this time, torches were lit along the long ramparts, illuminating the trenches. The camp gate is open. On the gatehouse, two sentries were holding rifles and standing next to a searchlight. Two carbide lamps were hung below the gatehouse, and the light was dazzling. Travelers pass through the gate, scan their dog tags at the manpower registration desk at the door, and then return tools and excess materials at the planning committee's storage point.
"Liu Zheng, right?" The female clerk in the human resources team looked at the personal information and photos displayed on the computer screen, and then compared them with his face, "Your barracks number is No. 14, Building B."
