Chapter 164

Back at the hotel, the experiment continued.

The rest is left to the digestive bacteria.

The next day, the experimental results came out.

Whether it's dirty bottles, broken meat or chili peppers, they are all broken down by digestive bacteria.

At a constant temperature of more than 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. It is found that a large amount of heat will be generated in the process of colony decomposition of organic matter.

This also proves that digestive bacteria are heat-resistant and heat-resistant.

The same is true for sewage treatment.

Next is the second experiment.

Whether it is water or stable inorganic salts, these exist naturally in nature. The second experiment needs to eliminate bacterial liquid to see how colonies and stable inorganic substances that have decomposed my small molecules will exist in nature.

Because of time, the experiment will be carried out uniformly on the last day of the outdoor experiment.

The next day, Zhou Xiao drove to the countryside near the city in the morning and to the industrial zone in the afternoon.

Jiangcheng is an old industrial city with uneven development.

The city center is the face of Jiangcheng City, so both infrastructure construction and city appearance are passable.

However, in some villages around Jiangcheng, there is still no access to tap water and natural gas.

Although there are garbage houses in such villages, the treatment rate is not high.

In addition, the villagers' houses are scattered around the village and there is no centralized residence, so it is very troublesome for them to throw their garbage into the garbage room, which leads to many villagers unconsciously throwing their garbage into the ditch at the door, and the domestic sewage at home is also directly discharged into the ditch.

Dirty, messy and poor is a conspicuous business card in the countryside around Jiangcheng.

Everyone in the village knows that suddenly an outsider will be very vigilant, and even something more serious will happen than the old aunt robbed the bottle last night.

Zhou Xiao had long expected this.

He found a decent person in the village through Jiangcheng and gave him two bottles of good wine to lead the way.

With acquaintances leading the way, things will be much easier.

Today, butcher Xiao in the village is the leader of the production team.

Knowing that Zhou Xiao and others are coming to inspect the sewage, butcher Xiao is actually quite happy.

While leading the way, he said: "the environment of our village should be renovated long ago. Every family discharges sewage directly, and the garbage is discharged into the river along with the ditch. It's a mess! I used to fish in the river when I was a child. Now I don't want to go to the river. "

Sure enough, Zhou Xiao smelled a pungent smell hundreds of meters away from the river. This smell should not only be the smell of domestic sewage.

Zhou Xiao said, "first collect some rural domestic garbage, then collect the sewage directly discharged by farmers in the ditch, and also collect some in the ditch next to the field to see if there are pesticide residues in the water in the ditch. Finally, let's go to the Bailong River."

Bailong River is the river where Xiao tulukou often fished when he was a child. This river is not only the main irrigation water source in the village, but also one of the important tributaries of the main river system in Jiangcheng.

After the Bailong River flows into the main water system of Jiangcheng, it will be introduced into the water plant by the water supply company to supply water to the residents of Jiangcheng after treatment.

Looking at the disgusting situation of Bailong River, I was thinking that most citizens in Jiangcheng were drinking tap water after such water treatment

Zhou Xiao felt a chill.

There is another important reason for taking sewage in rural areas.

There are many kinds and quantities of bacteria in rural sewage, such as Escherichia coli and so on.

Zhou Xiao wanted to know whether these bacteria had an impact on digestive bacteria.

This effect involves not only the survival of digestive bacteria, but also whether digestive bacteria will mutate under the influence of other colonies.

Butcher Xiao didn't know Zhou Xiao's identity. He thought Zhou Xiao and his team were sent by the city to investigate the water source and prepare to help the village deal with sewage and garbage.

Butcher Xiao asked with concern, "little brother, what can you do 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 I didn't have so many cancers when I was a child. I don't know why there are so many in recent years. Let's say that my separated second brother, Zhang, was young and only in his forties. He was in the advanced stage of liver cancer and left last year. My father, who also has liver cancer, left years ago. "

Butcher Xiao was followed by the old man who was watching the excitement and said:

"Isn't it? Zhang Laoer, his brother Zhang Laosan, was also diagnosed with cancer last year. It seems to be esophageal cancer. It's just 40. "

"Sister Wang is still cancer, gastric cancer..."

Just say it casually, there are seven or eight cancer patients.

Mo Li said in surprise, "so many cancers?"

Although there is a trend of mass and young age of cancer due to environment, living habits and other reasons, so many cancers are still very rare in a village.

This may explain a problem. The environment in the village must be polluted.

But can domestic sewage pollute the environment?

Zhou Xiao doesn't think so, nor do Mo Li and others.

Domestic sewage is absolutely impossible to cause cancer. There must be a cancer source in the village.

When people came to the white dragon river, they found the answer.

Why is the Bailong River so smelly and pungent? It's the factory on the other side of the village.

Jiangcheng is an old industrial city. Although there are new and old industrial areas and most factories are concentrated in the industrial areas, there are still scattered factories in the vast rural areas.

These factories are generally built in rural areas to reduce costs and avoid environmental protection and taxes. Most of them are furniture factories, leather shoes factories, fiberboard factories and other high pollution and high energy consumption enterprises.

These enterprises have existed locally for many years. Even the boss is local people, and many people in the village are still working there. Therefore, everyone turns a blind eye to whether there are procedures and violations.

The small workshop factory has no compliant sewage treatment equipment at all, and the sewage is discharged directly.

The furniture and leather goods industry uses the most chemicals and the most serious pollution. These things are discharged directly, such as the Bailong River.

As far as Zhou Xiaomu could see, the factory stretched out several pipes into the river, and the sewage with white or yellow bubbles was directly discharged.

These sewage mixed with the water of Bailong River flows down the river. Maybe it is diverted by the diversion canal built by farmers in downstream villages to irrigate crops, or it is directly sent to the water plant for treatment and sent to thousands of households.

Moreover, part of the sewage has also become an underground water system along the deep riverbed. Many households in the village should be using groundwater.

Butcher Shaw asked hopefully, "are you here to investigate pollution? When will the sewage in our village be solved? "
