Six types of fungi commonly used in sewage treatment

In the biological sewage treatment process, sewage treatment bacteria are the core key. Sewage treatment bacteria are responsible for degrading pollutants and purifying water quality. They have the advantages of simple operation, non-toxic and pollution-free, and no secondary pollution to protect the natural environment. It can effectively remove ammonia nitrogen, COD, BOD, SS, nitrate, sulfate, color, odor, toxic pollutants, etc., thus effectively degrading pollutants in water.

★Aerobic bacteria★

Aerobic bacteria are mainly used in the aerobic stage. Through aerobic action, they quickly oxidize ammonia into nitrite, and then further oxidize nitrite into nitrate through nitrifying bacteria, rapidly degrading ammonia nitrogen and removing organic pollutants in the water. The finished product is rich in Contains a variety of trace elements to promote the growth of local native microorganisms.

★anaerobic bacteria★

Utilize a variety of anaerobic bacteria to perform hydrolysis and acidification in an anaerobic environment to convert high molecular organic matter into small molecular organic matter, thereby significantly degrading and removing COD from the water. It can efficiently decompose various types of macromolecular organic matter.

★Nitrifying bacteria★

Nitrifying bacteria are a genus of aerobic bacteria that contain nitrite bacteria and nitrate bacteria. It plays an important role in the nitrogen cycle water purification process. It quickly oxidizes ammonia into nitrite, and then further oxidizes nitrite into nitrate through nitrifying bacteria, quickly eliminating the harm of nitrite in the water body. It is simple to use and has quick results.

★Denitrifying bacteria★

Denitrifying bacteria are bacteria that can cause denitrification. After a long period of targeted screening, domestication process, and precise fermentation, denitrifying bacterial flora that can adapt to different polluted environments have been cultivated. In an anoxic environment, denitrifying bacteria will The refluxing nitrate nitrogen is denitrified into nitrogen gas and evacuated to achieve the denitrification effect.

★COD degrading bacteria★

COD-degrading bacteria effectively degrade various types of polymer organic matter, efficiently absorb and degrade benzene, phenol and other related aromatic compounds and toxic substances, promote sludge settling performance, and improve the ability to remove organic matter in water. In the process of cultivating bacterial strains in the biochemical pool, appropriately adding some COD-degrading bacterial strains can effectively remove COD, so that COD can be better removed, which can better stabilize the biochemical system, effectively reduce COD, BOD and SS, and clean the water body. , reduce or eliminate the smell of sewage, decompose ammonia, hydrogen sulfide and other organic matter, thereby achieving the purpose of purifying water quality.

★Sewage treatment compound bacteria★

Sewage treatment complex bacteria are facultative bacteria, which can have dual functions of nitrification and denitrification at the same time. They can survive under anaerobic and aerobic conditions, and can expand and reproduce according to water quality conditions to achieve bacterial balance and make sewage treatment more efficient. Simple and efficient. The sewage treatment compound bacteria can quickly and efficiently degrade COD, NH4N and total phosphorus in aquaculture sewage and domestic sewage by utilizing the coordination between multiple microorganisms. At the same time, the efficient activator in the sewage treatment compound bacteria can quickly activate the bacteria and increase the organic matter in the water. It has the ability to remove, especially for various components that are not easily decomposed, and has the ability to open-loop degradation to accelerate the degradation of pollutants in water. After treatment with sewage treatment compound bacteria, the COD removal rate of sewage reaches more than 98%, the NH4N removal rate reaches more than 93%, and the total phosphorus removal rate reaches more than 90%.
