I'm collecting golden fingers from all over the world

(Thanks to my operating officer and many book friends for their support.)

After acquiring three water companies in Longhua County from [Green Water Water Group], and after integration, [Bikong Environmental Protection Development Co., Ltd.] started to develop rapidly like an off-road vehicle with the engine started.

On September 12, 2017, the weather was sunny.

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

The sewage from the entire Longhua County surged through the pipes, and the closed biological treatment workshop was injected with [Hydrocarbon Degrading Bacteria Mixture] - immediately, the grease, plastics and other petroleum products in the sewage were visible to the naked eye. It was swallowed up at a speed, and the stench of the sewage that came over suddenly dropped by several levels and became much clearer.

Then, the treated sewage flows into another workshop and passes through the orderly and scientifically placed [Dianjin Sang].

The roots of [Golden Mulberry] stretch out, it is like a bully, very rude. When the heavy metal components and inorganic salt components in the sewage encounter it, they are immediately robbed and turned into its nutrients.

At this time, the sewage has no odor and can be said to be crystal clear. It has barely met the lowest national level three emission standards. It may not meet the drinking standards, but there is no problem when used in environmental sanitation and greening.

Of course, [Bikong Environmental Protection Development Co., Ltd.] has higher requirements for itself. The sewage will be further processed until it reaches drinking standards and injected into reservoirs or used for other purposes.

Without considering the intellectual property costs of [Dianjin Mulberry] 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 by ten More than twice that.

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

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

First, use coarse gratings and fine gratings to gradually remove larger suspended solids and stones in the sewage to avoid damage to subsequent equipment. Then use a grit chamber to remove sand, stones, and large particles trapped in the sewage to avoid causing damage. Subsequent stasis, wear and clogging of equipment.

The main purpose of the [biochemical treatment stage] is to remove most organic pollutants, phosphorus, and nitrogen in 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 tank. The organic matter, nitrogen, phosphorus, etc. in the sewage entering the biochemical tank become nutrients for the microorganisms. Through a series of biochemical reactions, the Digest and decompose organic matter and remove inorganic matter such as phosphorus and nitrogen.

[Intensive treatment stage] After conventional biochemical treatment, the sewage still contains part of suspended solids, dissolved organic matter, nitrogen and phosphorus, etc., and does not meet the discharge standards. In-depth treatment measures need to be taken, such as coagulation sedimentation, depth filtration, and activated carbon adsorption. , biofilm separation technology, etc.

[Water Disinfection Stage] The main purpose of this stage is to kill a large number of bacteria and viruses in sewage and prevent the spread of viruses.

Disinfection methods are divided into physical methods and chemical methods

Physical disinfection methods mainly include heating, freezing, irradiation, ultraviolet rays and microwave disinfection.

Chemical disinfection methods mainly add chemical agents to sewage for disinfection, such as chlorine-containing compounds (sodium hypochlorite, bleaching powder, etc.), liquid chlorine, and ozone.

After passing through the above four stages of treatment, after the effluent from the sewage treatment plant reaches the Pollutant Discharge Standard for Urban Sewage Treatment Plants, it can be discharged to the outside world without polluting the river.

Of course, some solid waste and sludge will be produced during the sewage treatment process, and bacteria and viruses also exist in them. They need to be disinfected, dehydrated, dried and solidified, and then incinerated or treated in other ways.

After adopting the new biological treatment process provided by He Youman, in addition to the indispensable [pretreatment stage], the [biochemical treatment stage] and [disinfection stage] are directly treated by [Dianjin Mulberry] and [Hydrocarbon Degrading Bacteria Mixture] The treatment link has been replaced. In the end, only a simple biochemical treatment is needed for the treated sewage to easily meet high-level discharge standards.

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

Production sewage refers to industrial sewage and medical 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's not much difference.

Kill them all!

In terms of cost, without considering the investment cost, only the operating cost is calculated, and if it is all domestic sewage, the treatment cost of the original sewage treatment process is 0.4-0.6 yuan/ton.

This is very serious if it is industrial sewage. It may be several times to dozens of times higher.

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

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 from the water fee.

One cubic meter of water is one ton of water.

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

How much sewage is produced every day in Longhua County, including towns and villages?

According to county statistics, it is 114,700 tons/day.

Earn at least 1.13 yuan per ton, that is to say, [Bikong Environmental Protection Development Co., Ltd.] can earn at least 129,600 yuan per day from sewage treatment in Longhua County.

That’s 3.888 million yuan a month!

That’s a profit of 46.656 million yuan a year.

Of course, this is a very ideal situation.

Because the original sewage treatment plant had limited daily treatment capacity and could only process a maximum of 72,000 tons per day, a large amount of sewage was directly discharged, causing the ecological environment of Longhua County to become worse day by day!

Since Wu Siyuan asked [Bikong Environmental Protection Development Co., Ltd.] to take over Longhua County's water affairs business, he naturally would not sit back and ignore it.

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 daily sewage treatment capacity of the [Longhua County Sewage Treatment Plant] can easily reach 180,000 tons.

The reason why there is only 180,000 tons is not because the processing efficiency has reached the limit, but because the site area is not enough, so it can only reach 180,000 tons.

But even a daily processing capacity of 180,000 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?
