Sewage Treatment Bio Compounds

Common aerobic microbial technology treatment methods include activated sludge method, biofilm method, sewage treatment bacteria addition three categories.

The first type of microbial technology treatment method, activated sludge method: SBR, A/O, A/A/O/, oxidation ditch, etc.

SBR: SBR is short for sequential batch activated sludge process, which is a microbial technology treatment method of activated sludge wastewater operated by gap aeration. It is mainly characterized by orderly and clearance operation in operation. The core of SBR technology is THE SBR reaction tank, which integrates the functions of homogenization, sedimentation, biodegradation and secondary sedimentation into a non-sludge reflux system. It is suitable for sewage microbial technology treatment occasions where clearance discharge and flow rate change greatly.

A/O: A/O biological denitrification process is A microbial technology treatment system composed of anoxic and aerobic reactions. After the wastewater enters the anoxic tank, it successively goes through the stages of anoxic denitrification, aerobic organics removal and nitrification. The characteristics of the process are pre-denitrification, after nitrification, part of the effluent is transferred to the denitrification tank to provide nitrate.

A/A/O:A2/O process is also called A-A-O process, (anaerobic - anoxic - aerobic). In essence, this process should be anaerobic-anoxic-aerobic process, short for biological nitrogen and phosphorus removal process.

Second microbial technology, microbial membrane method: biological filter, biological rotary table, biological contact oxidation pool, etc.

Biological filter: biological filter is based on the principle of soil self-purification, on the basis of sewage irrigation practice, through the original intermittent sand filter and contact filter developed artificial microbial technology treatment method. It is a microbial technology treatment structure composed of gravel or plastic product filler, sewage and the microbial technology membrane gap contact on the surface of the filler, so that the sewage is purified.

Biological turntable: it is a microbial technology treatment structure composed of a sink and a rotating disk body partially immersed in sewage. The microbial membrane growing on the surface of the disk repeatedly contacts the sewage in the tank and the oxygen in the air, so that the sewage is purified.

Biological contact oxidation pool: derived from biological membrane method of a kind of microorganism wastewater treatment method, namely in the biological contact oxidation pool loading amount of filler, habitat use attached to the packing of the biofilm and sufficient supply of oxygen, by microorganism oxidation, oxidative decomposition of organic matter in the wastewater to achieve purification.

The third category is microbial technology, addition of microbial agents to sewage treatment

This method is suitable for the above two kinds of microbial technology treatment. On the basis of no need to transform the sewage treatment process, a complete set of microbial technology ecological chain is created in the sewage treatment system by adding microbial technology sewage treatment bacteria and using the biological characteristics of microbial technology sewage treatment bacteria. General microbial technology sewage treatment bacteria are divided into nitrifying aerobic bacteria, denitrifying anaerobic bacteria, and comprehensive nitrifying and denitrifying bacteria due to different working principles of treatment.
