In fact, the first thing that started here is not a market or a clothing factory.

Because compared with these two, the soy sauce workshop has higher priority.

Because the soy sauce factory changed its leader, Yuan Shuhai had already taken office in the compound.

Su He never expected that the new soy sauce factory leader would have a conflict with him.

Although I took some precautions and transported some soy sauce from southern Fujian, it did cause a lot of trouble for myself.

Not to mention anything else, it is a big expense to transport soy sauce from southern Fujian.

Originally, these things can be bought directly locally, and the transportation cost will not exceed ten yuan.

But when transported from southern Fujian, the expenses are much larger.

Not to mention anything else, the fuel costs alone are quite high.

What's more, there are manpower and material resources, as well as the depreciation costs of trucks.

This will also affect the transportation of seafood, which is another loss invisibly.

Su He remembered in his heart that if he had the chance, he would definitely have to fight with Wu Cuicui.

It’s true that relying on his background, he is unscrupulous.

When you walk in, there is some smell.

To be honest, brewing soy sauce is a great pollution to water quality.

For this reason, Su He also found some solutions to specifically deal with the sewage here.

But at this stage, the domestic control over these things is not very strict, and Su He has no choice.

He just doesn't want to pollute his hometown.

Soy sauce wastewater mainly comes from the process of koji production, fermentation, back-seasoning and packaging, including cleaning wastewater in production sites and equipment, raw material soaking wastewater, product waste overflow, cleaning and disinfection wastewater in fermentation tank pool flushing wastewater and packaging containers, as well as some employees

, office and domestic wastewater.

There are several options for sewage treatment.

The first is the physical method, which is also the only thing Su He can take at present.

Physical methods for the treatment of industrial wastewater in soy sauce include filtration, filtration, regulating, precipitation, air floatation, centrifugal separation, filtration, microfiltration, etc.

The first 5 processes are mainly used for pretreatment or primary treatment, while the last 3 processes are used for deep treatment.

Screening is the most widely used method in pretreatment, separating dispersible suspended solids with larger diameters from wastewater;

The skimming method can eliminate the impact of grease on the corrosion of process equipment and the effluent water quality, which is conducive to the recycling of grease. The water quality of soy sauce industrial wastewater changes greatly, and the adjustment pool can be used to adjust its change range;

Precipitation is used to separate the solid and liquid phases in biological treatment;

The air float method is used to remove emulsified oil, some active substances and other suspended substances in soy sauce wastewater. If the wastewater is to be deeply treated, these three processes can be used.

The physical method has low cost of processing, but the water quality of the effluent cannot be achieved separately, and can only be used as an auxiliary process.

But at present, what Su He can do is just a physical method.

As for chemical methods, or biochemical methods, they need to be followed up.

In fact, the chemical method is mainly neutralization method or redox method. As long as the corresponding raw materials can be purchased, it is also easy to do it.

In fact, the main thing is to help these wastewater degrade.

It’s a pity that these chemical raw materials are hard to buy.

"When I arrived in Yuzhang, or went to Yanjing, I searched hard and I should be able to find it."

He still has to do a good job in environmental pollution.

If it is directly discharged, it will probably take no time for the surrounding environment to become smelly.

Ye Zhenming said: "I think you are still arranging people to deal with the wastewater? Why don't you pour it directly into the water? Anyway, the water in the river will flow down and dilute it."

Ye Zhenming didn’t want to harm others, but he didn’t want to die.

He actually didn't know this. He felt that there was a lot of water in the rivers. If you just dilute it, it would be fine.

Su He had to share with him the situation in this regard: "These things are difficult to degrade and can easily affect the water quality.

Although poured into the river, the river itself has a certain ability to self-purify.

But we cannot rely on these, because we are not just using rivers.

In fact, I am very worried that with the increasing number of factories and the progress of domestic industrialization, although the economy and life have improved, the environment has become worse."

The environment becomes worse, but it's not just a sentence.

There are many problems in this, such as the safety of domestic water and the environment becoming less livable.

It will also lead to an increase in the rate of carcinogenicity, and the harm of increasing industrialization is one of the important reasons.

But there is no way. If you don’t develop, you will fall behind and be beaten.

This is also helpless.

You can’t have both fish and bear’s paws, maybe it’s such a sadness.

Although Ye Zhenming didn't understand these considerations, since Su He, a well-educated person, said so, he took them seriously.

It is to take it to heart, but he has no choice but to rely on Su He to solve it himself.

What can an old man in the countryside who only recognizes a few words?

After watching it, several of Yu Tu's comrades guarding here.

After all, it is something to be imported. Besides, there must be someone who stays behind the production line.

Seeing Su He coming, Yu Tu's comrades did not leave their posts.

Su He was very satisfied with this. Although the veterans did not know so many ways to flatter.

But what Su He wants is their quality, what do you want so many flatteries?

He doesn't want others to flatter and flatter. As long as he does something well, it's a good thing.

Su He observed it and nodded: "My soy sauce can be used for a while. It seems that there is no need to buy soy sauce from southern Fujian anymore."

Ye Zhenming asked strangely: "I just watched it. Are you different from your soy sauce?"

The concept of light soy sauce and dark soy sauce, plus Su He’s subsequent additions to light soy sauce and dark soy sauce, let’s upgrade step by step.

Su He smiled and said, "In fact, there are two different soy sauces, one is called light soy sauce and the other is called dark soy sauce.

Among them, the ingredients are actually similar, but light soy sauce tends to be seasoned. In the future, light soy sauce is mainly used for cooking or cold dishes.

As for dark soy sauce, it is mainly used to adjust the color. For example, when we make braised pork, although we have to stir-fry the sugar color at the beginning, the color is already very good.

But adding a certain proportion of dark soy sauce will make the braised pork look better…”

Ye Zhenming felt it was very troublesome, but Su He smiled and said, "This is different from rock sugar, yellow sugar and white sugar. It is not very vivid, but that's it. After subdividing it, it will be more professional and the taste will become better.

.”

"Forget it, I don't understand these."

He doesn't even know how to cook, let alone these seasonings.

If it were the kind that used to be, I wouldn't even help the oil pot when it was poured, my grandfather Ye Zhenming was such a person.

Well, it's a bit exaggerated, but that's the truth.

After a walk around, the two returned to the village.

Su He originally planned to go back after a walk, but he couldn't leave after the village held a wedding ceremony.

Ye Chuanxiu said: "I forgot to tell you before. Since you haven't left, let's go to the mat together."

Since he was going to have a meal, Su He would have to pay for any money.

"Mom, do you have a red seal in your hand? I'll give me some money."

Ye Chuanxiu rolled his eyes: "You are a child and you have not started a family, and we have not separated. What kind of money do you give?"

Although that's what it means, there is no adulthood, no family, and no family separation, so there is no need to pay two shares.

But isn’t Su He promising?

When eating a meal like this, you won’t even pay a portion of money, which will easily make the villagers talk.

Although Ye Chuanxiu said that, he still went to find a piece of red paper, cut it, and gave it to Su He.

At this time, the finished red envelopes have not yet come out. There is no such thing as just going to the store and spending a few dollars more than one dollar to buy a dozen red envelopes.

When rural people give red envelopes, they just give money directly.

Someone will take it outside and record the amount of people and money.

This is what is prepared to repay favors to the latter.

Su He thought about it and took a five-dollar one and wrapped it directly in red paper.

He originally wanted to give him ten yuan, but ten yuan was too much, which was equivalent to someone's salary for one month, which was not appropriate.
