Why are microbial agents recommended for sewage treatment?

As environmental protection has become the focus of people's increasing attention, sewage treatment has also attracted more and more attention, a variety of sewage treatment technology and methods emerge in endlessly, roughly a point of physical method, chemical method, biological method and so on.

Take the most concerned ammonia nitrogen index as an example, biological process has A/O process, SBR process, physical method has blown stripping, reverse osmosis technology, chemical law has broken point chloride method, chemical precipitation method, etc.

Among these methods, microbial treatment of sewage has shown great advantages. Using microorganism to treat sewage can solve ammonia nitrogen, total nitrogen, COD and other problems, and the treatment effect is ideal, the effluent is stable.

Microbial species are diverse and complex. Different kinds of microorganisms have different metabolic pathways, can use different energy sources, and are targeted to solve different wastewater problems. For example, autotrophic nitrifying bacteria can quickly eliminate ammonia nitrogen in water, while total nitrogen removing bacteria can quickly eliminate nitrite and nitrate in water, so as to solve the problem of total nitrogen.

Microorganisms have various metabolic pathways, short incubation period, strong reproductive capacity and large body surface area. As long as the conditions are suitable, microorganisms can reproduce rapidly in sewage and decompose pollutants with high efficiency.

As organisms, microbes also have a huge advantage over other treatments: they are adaptable and stress-resistant. So microbes can be domesticated in sewage systems. After domestication, microorganisms can better adapt to sewage treatment systems, thus improving sewage treatment efficiency, and have the ability to resist shocks.

Microbial treatment can not only remove organic matter, pathogens, toxic substances, but also remove odor, improve transparency, reduce chroma and other effects, the treatment effect is good. As long as the right microorganisms are found and given the right conditions, almost all pollutants can be degraded or transformed.

And with microbial sewage treatment, safe and non-toxic, no secondary pollution, but also to avoid the waste of water resources.

As we all know, when adding chemicals to the environment, it is difficult to control the amount just enough to deal with the pollution, and the excess chemicals into the environment will cause secondary pollution to the environment.

But microbes don't have that problem. Most microorganisms live in activated sludge and will not be discharged directly with the discharge of sewage. The threat to the environment is much lower if the strain is screened from native nature.

Unlike other treatment methods, microbial treatment of wastewater is the final conversion of pollutants in the wastewater into carbon dioxide, nitrogen, water and sludge. Nitrogen dioxide, nitrogen and water, are non-toxic and harmless, sludge can also be converted into organic fertilizer through sludge digestion, sludge can also be made into building materials. The results show that there are no secondary pollutants in microbial wastewater treatment and it will not pollute the environment.

In addition, microbial sewage treatment, simple, do not repeatedly add, save operating costs.

The principle of microbial sewage treatment is that microorganisms carry out life activities, and play a role in degrading organic pollutants in the dissolved state or colloidal state in the wastewater, so that the wastewater can be purified. As long as the activated sludge is cultivated well in the sewage treatment system and suitable living conditions are provided for microorganisms, microorganisms can always play a role without repeated addition of bacteria, which is impossible for chemical and physical treatment.

Moreover, the use of microbial agents to treat sewage, do not need high temperature, high pressure, mild conditions, pollutants through enzyme catalysis can be efficient and relatively complete, large treatment capacity, low treatment cost, only 30% ~ 50% of the physical, chemical method.

Sewage treatment with microorganisms, simple operation, simple delivery, low requirements on the operation technology content, can avoid laying unelegant mechanical equipment, reduce the area of land, capital costs, operating costs, energy consumption, management, and can meet the requirements of high efficiency and low consumption.
