Chapter 357 New Technology, New Efficiency

(Thanks to my operating officer and the support of many book friends.)
After the acquisition of [Greenwater Water Group]'s three water companies in Longhua County, after integration, [Bikong Environmental Protection Business Development Co., Ltd.] started a rapid development like an off-road vehicle with its engine running.

On February 2017, 9, the weather was fine.

Because of the simple structure, the original sewage treatment production line and tap water purification production line of [Greenwater Water Group] were finally completed after many days of overtime work.

The sewage in the entire Longhua County rushes in from the pipeline, and the closed biological treatment workshop after renovation is injected with [hydrocarbon-degrading bacteria mixture]—suddenly, the oil, plastic and other petroleum products in the sewage are visible to the naked eye The speed was swallowed up, and the stench of the sewage that rushed over suddenly dropped several levels, and became much clearer.

Then, the treated sewage is poured into another workshop, and passes through the [Dian Jinsang] that is arranged in an orderly and scientific manner.

The roots of [Dianjin Mulberry] are stretched, it is like a bully, very rude, the heavy metal components and inorganic salt components in the sewage will be plundered immediately and turned into its nutrients.

At this time, the sewage has no stench, and it can be said to be crystal clear. It has barely met the lowest national standard three-level discharge standard. It may not meet the drinking standard, but there is no problem in using it for environmental sanitation and greening.

Of course, [Bikong Environmental Protection Business Development Co., Ltd.] has higher requirements for itself, and the sewage will be further treated until it reaches the standard of drinking, and then injected into the reservoir or used for other purposes.

Without considering the intellectual property costs of [Dianjinsang] and [Hydrocarbon Degrading Bacteria Mixture], but only considering their production costs, the cost of sewage treatment not only did not increase, but decreased, but the treatment efficiency increased tenfold. More than double.

The original sewage treatment method mainly uses physical (filtration, precipitation), chemical (chemical reaction) and biological (biological eating) methods to eliminate the pollutants in the water. Generally, it needs to go through four treatment stages. [Pretreatment stage], then [Biochemical treatment stage], then [Intensive treatment stage], and finally [Water disinfection stage].

The main purpose of the [pretreatment stage] is to remove suspended solids, sand and gravel in the sewage, and degrade macromolecules.

First, use coarse and fine screens to gradually remove larger suspended solids and stones in the sewage to avoid damage to subsequent equipment, and then use a grit chamber to remove sand, stones, and large particles in the sewage to avoid causing damage Bruising, wear and clogging of subsequent equipment.

[Biochemical treatment stage] The main purpose is to remove most of the organic pollutants, phosphorus and nitrogen in the sewage.

Biochemical treatment processes are often used in China, including oxidation ditch process, A2/O (anaerobic/anoxic/aerobic) process, improved A2/O process, SBR process (intermittent activated sludge process), etc.

The principle of biochemical treatment process, simply put, is to cultivate microbial strains in the activated sludge of the biochemical pool, enter the sewage of the biochemical pool, and the organic matter, nitrogen, phosphorus, etc. in it become the nutrients of the microorganisms. Through a series of biochemical reactions, the Organic matter is digested and decomposed to remove inorganic matter such as phosphorus and nitrogen.

[Intensive treatment stage] After conventional biochemical treatment, the sewage still contains some suspended solids, dissolved organic matter, nitrogen and phosphorus, etc., which cannot meet the discharge standards, and advanced measures need to be taken for treatment, such as coagulation sedimentation, deep filtration, and activated carbon adsorption. , biofilm separation technology, etc.

[Outlet water disinfection stage] The main purpose of this stage is to kill a large number of bacteria and viruses in the sewage and prevent the spread of viruses.

Disinfection methods are divided into physical and chemical methods

Physical disinfection methods mainly include heating, freezing, irradiation, ultraviolet and microwave disinfection, etc.
The chemical disinfection method is mainly to add chemical agents to the sewage for disinfection, such as chlorine-containing compounds (sodium hypochlorite, bleaching powder, etc.), liquid chlorine, and ozone.

After the above four stages of treatment, the effluent of the sewage treatment plant can be discharged outside after reaching the "Pollutant Discharge Standards for Urban Sewage Treatment Plants", without polluting rivers.

Of course, some solid waste and sludge will be produced during the sewage treatment process, and bacteria and viruses also exist in them. After disinfection, dehydration, drying and solidification, they will be incinerated for harmless treatment, or treated in other ways.

After adopting the new biological treatment process provided by He Youman, in addition to the essential [pretreatment stage], [biochemical treatment stage] and [disinfection stage] are directly replaced by [Golden Mulberry] and [Hydrocarbon Degrading Bacteria Mixture] The treatment link has been replaced, and in the end, it only needs to perform a simple biochemical treatment on the treated sewage to easily meet the high-level discharge standard.

This new process not only has miraculous effects on domestic sewage, but also has excellent effects on production sewage.

Production sewage is industrial sewage, medical sewage and other sewage.Because of the complex composition, the cost of treating one ton of production sewage and one ton of domestic sewage is very different.

But for the new process, there is not much difference.

Kill!

In terms of cost, without considering the investment cost, only the operation cost is calculated, and in the case of domestic sewage, the treatment cost of the original sewage treatment process is 0.4-0.6 yuan/ton.

If it is industrial sewage, it will be serious, and it may be several times to dozens of times.

But the new biological treatment process provided by He Youman is powerful. The cost of sewage treatment is less than 0.1 yuan/ton, which is 0.08-0.09 yuan/ton. The cost is four or five times cheaper, whether it is domestic sewage or Produce sewage.

And how much is the sewage treatment fee in Longhua County?

The sewage treatment fee of 1.22 yuan per cubic meter is collected by the water company in the water fee.

One cubic meter of water is one ton of water.

In other words, [Bikong Environmental Protection Business Development Co., Ltd.] can earn at least 1.13 yuan per ton of water after using the new technology.

And Longhua County, including townships and villages, how much sewage is produced every day?
According to county statistics, it is 11.47 tons/day.

Earn at least 1.13 yuan per ton, that is to say, [Bikong Environmental Protection Business Development Co., Ltd.] can earn at least 12.96 yuan a day in sewage treatment in Longhua County.

One month is 388.8 million yuan!

One year is a profit of 4665.6 million yuan.

Of course, this is an ideal situation.

Because the original sewage treatment plant had a limited daily processing capacity, it could only process 7.2 tons per day at most, and a large amount of sewage was directly discharged, causing the ecological environment of Longhua County to deteriorate day by day!

Since Wu Siyuan let [Bikong Environmental Protection Business Development Co., Ltd.] take over the water business in Longhua County, he naturally would not sit idly by.

The original sewage treatment plant had a limited treatment capacity, but after using the new process, this problem no longer exists.

According to Wang Hang's estimation, the current [Longhua County Sewage Treatment Plant] can easily handle 18 tons of sewage per day.

The reason why there are only 18 tons is not that the processing efficiency has reached the limit, but because the site area is not enough, so it can only reach 18 tons.

But even a daily processing capacity of 18 tons is enough for Longhua County.

Wu Siyuan attaches great importance to this business and has given such great support. Wang Hang thinks, what should he do?
