An overview of the
FRP integrated sewage treatment equipment adopts biological treatment technology, which is a technology that utilizes the metabolism of microorganisms, mainly bacteria, to oxidize, decompose and absorb the soluble organic matter and some insoluble organic matter in wastewater, and converts them into harmless stable substances so as to purify water. In the process of modern biotechnological treatment, there are mainly three categories: aerobic biooxidation, aerobic biodegradation and anaerobic digestion and degradation.
The equipment size
The overall size of the FRP integrated sewage treatment equipment is 10.5 2.25 2.5m, and the process adopted is AO process. The main body of integrated sewage treatment equipment is made of glass fiber reinforced plastics (FRP), with channel steel reinforcement inside. The equipment is internally treated with epoxy coal tar + epoxy zinc rich anticorrosion, and externally treated with three oils and two cloth glass wire anticorrosion.
Fiberglass integrated sewage treatment equipment anoxic tank installation packing bracket and combination packing, with perforated aeration pipe at the bottom,
Packing assembly density is 70%.
The aerobic tank is equipped with packing bracket and combined packing, and the bottom is equipped with microporous aerator and aeration bracket.
The installation density of composite packing is 70%, and the number of microporous aerator is 3 /m2.
A nitrifying liquid reflux pump was added in the aerobic pool to reflow the wastewater from the nitrifying reaction in the aerobic pool to the anoxic pool for denitrification, so as to remove most ammonia nitrogen in the sewage.
Aeration of anoxic pool and aerobic pool is provided by fan.
A sludge backflow pump is added to the sedimentation tank to transfer part of the sludge from the sedimentation tank to the sludge tank, part of the backflow to the aerobic tank, and part of the backflow to the regulating tank.
The sedimentation tank is made into a conical tank to facilitate the return of sludge.
The sludge returned to the aerobic tank provides nutrients for the cultivation of active bacteria.
The sludge tank, as a temporary storage tank, is cleaned regularly.
As a small cistern, the water is discharged after reaching the standard.
The processing capacity of the equipment is strong, according to the process selection can meet the national level B, level A standards.
