Abstract

The invention discloses an energy-saving biochemical nitrogen and phosphorus removal treatment device. A catalytic oxidation tank of the device is filled with ozone catalysis particles in the form ofa fixed bed, and the ozone catalysis particles are prepared from, by weight, activated alumina particles, copper oxide, titanium dioxide, polyethylene glycol and polyvinyl alcohol. Post-biochemical BAF tanks also include an anaerobic tank and an aerobiotic tank, a lower screening plate and an upper screening plate are installed at the lower portion and the upper portion of the aerobiotic tank respectively, a carrier is prepared from, by weight, high-density polyethylene resin, low-density polyethylene, bamboo charcoal powder, wood powder, lignin, methylene dichloride, diethyl guanidine sulfate, N,N'-ethylene bis-stearamide, maleic anhydride, dicumyl peroxide, gelatin, magnetic powder and pentaerythritol stearate. The energy-saving biochemical nitrogen and phosphorus removal treatment device achieves wastewater COD removal, decolorization, deodorization and degradation of toxic pollutants in the catalytic oxidation treatment process of sewage in the coal chemical industry.

Description

technical field [0001] The invention relates to an energy-saving biochemical denitrification and phosphorus removal treatment device, which belongs to the technical field of sewage denitrification and phosphorus removal. Background technique [0002] Most coal gasification plants in China adopt the Lurgi gas production process. The waste water pollutants produced by this process have a high concentration and complex organic components, mainly including phenolic compounds, polycyclic aromatic compounds, and heterocyclic compounds containing nitrogen, oxygen, and sulfur. Compounds and fatty compounds are highly toxic and difficult to biodegrade. If the coal-to-gas wastewater is not properly treated and discharged beyond the standard, it will cause serious pollution to the ecological environment. Therefore, how to effectively treat the coal-to-gas wastewater and achieve wastewater discharge standards has become an international problem. [0003] At present, high concentrations...
