Chapter 164 (1/2)

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.
