The Black Technology Era of Xueba

"It's over. It will take a while."

Xiao Ming allows workers to build a sewage treatment tank here to save costs to the greatest extent and make use of existing local resources.

For example, sinking ponds are not made of concrete, but are in the form of deep pits. For example, the heating problem of the first biological sewage treatment tank used a solar heating board. In the future, it can be used to make a microbial accumulation pit and use the fermentation of waste organisms to heat up.

The local farmers are still relatively friendly, and they did not ask for compensation for Xiao Ming's workers digging a ditch beside the ditch. When everyone was working, they brought tea and fruit to Xiao Ming and others.

In fact, most of the people of Xia Guo are kind and simple. Knowing that your behavior is for their good, they will not embarrass you.

The next thing is to wait quietly.

After three o'clock in the afternoon, the early summer sunshine was quite warm.

The student girls are still more able to endure hardships, and Wen Xueqing's sweaty mud is not as good as the girls in the city.

Wen Xueqing wiped the sweat on her forehead with her sleeve and said, "It's almost time!"

The workers opened the valve on the upper part of the second biological treatment tank, and the cool water flowed out from the upper part and flowed into the third plastic pool.

Through the adjustment of technology, in the future, the water in the second biological treatment tank will automatically overflow from the upper part after being cleaned, and it is guaranteed that the overflowed water must meet the standard of Class I water.

Wen Xueqing said: "Test the water quality and pay attention to the bacteria content."

Xiao Ming recorded every detail of the experiment with a mobile phone, and Wen Xueqing opened a laptop to record detailed experimental data.

After half an hour, the test results came out.

The lab assistant said: "Perfect!"

Wen Xueqing said: "The data is for me."

Because it is a field experiment, the sealing is not strong, and the deposition time is short, so the treated water index is a little worse than the laboratory, but it still meets the Class I water standard and is drinkable.

Then hand the data to Xiaochu, and let Xiaochu enter the experimental software form.

The sewage treatment experiment that lasted for eight months was completed, and the papers were formally published after handing over the data from the field tests to Gao Siqi.

The farmers came around and looked at the cool water in the plastic bucket and asked, "My God! How did the black water become cool!"

"Is there any chemical in this bucket?"

"It's amazing! Sewage treatment plants won't treat it so cleanly."

Xiao Ming did not intend to remove the experimental equipment. This small sewage treatment tank can benefit local farmers.

Xiao Ming introduced: "We are students of Jiangcheng University. I am bothering you today to do a sewage treatment experiment, and the experiment is now successful."

Xiao Ming pointed to the sewage treatment equipment and said, "The sewage treatment equipment has been installed. The microbial treatment method we use has been treated with potable water after treatment in two treatment tanks. You can use the water here to feed vegetables and feed. Livestock, of course, can be drunk by themselves. "

Someone could not bear it, put a plastic bottle in a bottle and took a sip. "That's great! It tastes much better than groundwater! There is always a smell of metal in groundwater."

"I taste it, I taste it!" More people crowded forward.

"It tastes really good! I will drink water here and drink it without having to waste electricity!"

"That's it!"

Wen Xueqing, who was very responsible, heard the villagers say that the groundwater they pumped up had a metallic smell.

During the sewage treatment experiment, Wen Xueqing was very sensitive to water quality and had a bad feeling.

Wen Xueqing looked at Xiao Ming, and Xiao Ming nodded.

Wen Xueqing said immediately: "Who are you helping me pick up the groundwater you pumped out? I will help you test the water quality."

One elderly man with prominent eyes and yellow complexion said, "I'll go."

A few minutes later, the old man came out with a mineral water bottle and said, "This is just the water."

The groundwater was not as cool as expected, with some turbidity and yellowing.

Villagers are drinking such water?

The old man also said with a sigh: "A few years ago, our wells had water at a depth of seven meters, and now we have to hit a depth of seventeen to eight meters to have water. These groundwaters are this color, and we have to settle down before drinking.

In fact, it is not necessary for the old man to say that Xiao Ming also knows that the surrounding area is full of factories and enterprises. The office buildings of enterprises are as low as five or six meters high and as many as ten meters high.

The first priority of everyone in the construction of high-rise buildings is to dig deep foundation pits for drainage.

Wen Xueqing was busy testing the water quality. Twenty minutes passed, and she did not expect it.

Passing the test results to Xiao Ming, Wen Xueqing said: "The content of iron and manganese is seriously exceeded, which is thousands of times the drinking water standard. This water cannot be drunk!"

The groundwater was severely polluted. The cause of such serious pollution is inseparable from the pollution of surrounding enterprises, especially the deep processing enterprises of iron ore and manganese steel. Xiao Ming even seriously suspected that these enterprises did not follow the sewage treatment procedures at all and directly discharged sewage into river ditches or directly into the ground.

Wen Xueqing was trembling with indescribable anger. She said, "Drinking this water is dead!"

Later, Wen Xueqing asked: "Are there any people who have died in this village in recent years?"

Wen Xueqing opened the villager's box ~ www.NovelMTL.com ~ why not, people die every year. "

"Liu Sanye just left last month, and Aunt Li also left two months ago."

"What is it? Liver cancer?" Wen Xueqing asked.

This surprised the villagers.

"how do you know!?"

"In recent years, several liver cancers have died in the village."

"Two more cirrhosis."

"Don't drink this water," Xiao Ming said. "The groundwater can't be drunk, it's already polluted."

The villagers said, "Where is it so serious, we should drink after simmering. It should be fine."

"What water to drink without groundwater?"

Xiao Ming handed a box of the culture medium to the villagers and said, "Drink the water treated here first. This is the culture medium. Add one bag each month to the two treatment areas. In addition, you must continue to think of ways. It's best to apply for tap water. "

"Sister Xue, let's go." Xiao Ming said: "The equipment is left here, and the equipment is packed."

"But! But!" Wen Xueqing said, "their groundwater can't be drunk, shall we help them?"

"I know." Xiao Ming's expression was very serious. "I can build a large sewage treatment plant here, but there are many villages like Xia Guo. Water pollution is just a small point. What about food? Air? We cannot change any of the status quo, and all we can do is to speed up the promotion of wastewater treatment technology. "

Wen Xueqing sighed and said, "I can only help them propagate in the media, I appeal."

When leaving, Wen Xueqing looked at the indifferent villagers' sour noses, and the ignorant were fearless. What did we lose at the same time as economic development?

Xiao Ming's team left the village and he felt some responsibility.
