The richest man starts with black technology
Chapter 164
Back at the hotel, the experiment continued.
The rest is handed over to the digestive bacteria.
The next day, the results of the experiment came out.
Whether it is a dirty bottle, minced meat, or pepper, all are decomposed by digestive bacteria.
At a constant temperature above 40 degrees, organic compounds are decomposed by digestive bacteria into stable compounds similar to small molecules such as water, carbon dioxide, and nitrate.
It is certain that the digestive bacteria solution is weakly acidic. Experiments have found that a large amount of heat will be generated during the decomposition of organic matter by the colony.
This also proves that digestive bacteria are heat-tolerant.
The same is true for sewage treatment.
Next is the second experiment.
Whether it’s water or stable inorganic salts, these are naturally occurring in nature. In the second experiment, we need to eliminate the bacterial liquid to see if the colonies and stable inorganic substances that have decomposed my small molecules will interact in nature. How to exist.
Due to time reasons, the experiment will be conducted uniformly on the last day of the outdoor experiment.
The next day, Zhou Xiao drove, taking everyone to the countryside near the city in the morning and the industrial zone in the afternoon.
Jiangcheng is an old industrial city and its development is also very uneven.
The city center is the face of Jiangcheng City, so both the infrastructure construction and the city appearance are decent.
However, some villages around Jiangcheng still have no access to tap water or natural gas.
Although there are garbage houses in such villages, the treatment rate is not high.
In addition, the residences of the villagers are scattered around the village and there is no centralized living. It is also very troublesome for them to throw garbage in the garbage room. This has caused many villagers to unconsciously throw garbage into the ditch at the door. Sewage is also directly discharged into the river.
Dirty and chaos is the more conspicuous business card of the countryside around Jiangcheng.
Everyone in the village knows everyone, and suddenly there are outsiders who will be very vigilant, and even more serious things will happen than the old aunt grabbing the bottle last night.
Zhou Xiao had already expected this matter.
Through Jiangcheng, he found someone in the village who could speak, and gave two bottles of good wine to let him lead the way.
With acquaintances leading the way, things are much easier.
Today, the leader of the village is Xiao Butcher and the captain of the production team.
Xiao Tufu was actually quite happy to learn that Zhou Xiao and others were coming to inspect the sewage.
While leading the way, he said: "The environment in our village should have been improved a long time ago. Every household is drained of sewage directly, and garbage is also discharged into the river along the ditch, which is messy! I used to fish in the ditch when I was a child, now I don’t want to go to the river."
Sure enough, Zhou Xiao smelled a pungent smell when he was a few hundred meters away from the river. This smell should not only be the smell of domestic sewage.
Zhou Xiao said: “You first collect some rural domestic garbage, and then collect the sewage directly discharged by farmers in the ditches, and also collect some in the ditches next to the fields to see if there are any pesticide residues in the water in the ditches. By the Dragon River."
The Bailong River is the river Xiao Tufu used to fish when he was in his middle school and childhood. This river is not only the main water source for the village, but also one of the important tributaries of the main river system in the city.
After the Bailong River merges into the main water system of Jiangcheng, it will be introduced into the water plant by the water company to supply water to the residents of Jiangcheng after treatment.
Looking at the disgusting situation of Bailong River, I was thinking that most of the residents in Jiangcheng were drinking the treated tap water...
Zhou Xiao had a chill.
There is another important reason for taking sewage in rural areas.
There are many types and quantities of bacteria in rural sewage, such as E. coli.
Zhou Xiao really wants to know whether these bacteria have any effect on digestive bacteria.
This effect is not only related to the survival of digestive bacteria but also whether digestive bacteria will mutate under the influence of other colonies.
Xiao Tufu didn't know Zhou Xiao's identity, thinking that Zhou Xiao and his team were sent by the city to investigate the water source and prepare to help the village treat sewage and garbage.
Xiao Tufu asked with concern: "Brother, what are you doing to solve the problems in our village? There are several new cancers in our village every year, and several people die of cancer every year. I remember that I didn’t have so many cancers when I was young. , I don’t know how so many years. I’m just over forty years younger than my second child Zhang. I have advanced liver cancer and left last year. My dad also has liver cancer.
Butcher Xiao followed the uncle who was watching the excitement and said in a rush:
"Isn't it? Zhang Lao Er and his brother Zhang Lao San, was also diagnosed with cancer last year. It seems to be esophageal cancer. He was just 40.
"Wang Ersao is still cancer, stomach cancer..."
Everyone just said casually, there are seven or eight cancer patients.
Mo Li was surprised: "So many cancers?"
Although due to the environment, living habits and other reasons, cancer is showing a trend of mass-occurrence and younger age, it is still very rare to have so many cancers in a village.
This may indicate a problem. The environment in the village must be polluted.
But can domestic sewage pollute the environment?
Zhou Xiao did not think so, nor did Mo Li and others.
Domestic sewage is absolutely impossible to cause cancer, and there must be a source of cancer in the village.
When everyone came to the Bailong River, they found the answer.
Why is the Bailong River so smelly and has such a pungent smell, because on the other side of the village is the factory.
Jiangcheng is an old industrial city. Although there are new and old industrial areas, most of the factories are also concentrated in the industrial areas, but in the vast rural areas, there are still fragmentary factories.
These factories are generally built in rural areas to reduce costs, avoid environmental protection, taxation, etc. Most of them are high-polluting and high-energy-consuming enterprises such as furniture factories, leather shoe factories, and fiberboard factories.
These companies have existed in the local area for many years, and even the bosses are locals. Many people in the village are still working in them. Therefore, everyone keeps a blind eye on whether there are procedures and whether they violate regulations.
Small workshop-style factories have no compliant sewage treatment equipment at all, and all sewage is discharged directly.
The furniture and leather goods industries use the most chemicals, and the pollution is also the most serious. These things are directly discharged like the Bailong River.
As far as Zhou Xiao could see, the factory extended several pipes deep into the river, and the sewage with white or yellow bubbles was directly discharged.
The sewage is mixed with the water of the Bailong River and flows down. It may be diverted by diversion canals built by farmers in downstream villages to irrigate crops, or it may be directly sent to water plants for treatment and sent to thousands of households.
Moreover, part of the sewage has also turned into a groundwater system along the depths of the riverbed, and many households in the village are probably using groundwater.
Xiao Tufu asked hopefully: "Are you here to investigate the pollution? When will the sewage in our village be resolved?"
