Abstract

The invention belongs to the field of sewage treatment, and relates to a treatment system for wastewater of a kitchen waste aerobic degradation treatment plant. The water outlet of a wastewater tank is connected with an oil separation primary sedimentation tank; the water outlet of the oil separation primary sedimentation tank is connected with a three-phase separation centrifuge; the water outletof the three-phase separation centrifuge is connected with a cooling tower; the water outlet of the cooling tower is connected with an adjusting tank; the water outlet of the adjusting tank is connected with an cavitation air flotation machine; the water outlet of the cavitation air flotation machine is connected with a pressurized dissolved air flotation machine, the water outlet of the pressurized dissolved air flotation machine is connected with a two-phase anaerobic reactor, the water outlet of the two-phase anaerobic reactor is connected with an up-flow sludge bed-filter, and the water outlet of the up-flow sludge bed-filter is connected with a sequencing batch activated sludge reactor for enhanced denitrification. Oil separation primary sedimentation and the three-phase separation centrifuge are serially connected, meanwhile, a double-air-floatation system is adopted, so that the oil, water and solid three-phase separation efficiency is improved, and the suspended matter removalrate and the oil removal rate can reach 90% or above.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a treatment system for waste water of a food waste aerobic degradation treatment plant. Background technique [0002] Affected by my country's environmental carrying capacity and relevant national policies, the classification of urban waste is currently in full swing. Among them, kitchen waste is a part of urban solid waste, and its disposal plays a decisive role in the surrounding environment. At present, there are mainly two treatment methods in food waste treatment plants, namely anaerobic fermentation method and aerobic degradation method. Food waste treatment plants using aerobic degradation methods will produce high-concentration food waste wastewater during the process of processing food waste. [0003] The organic carbon, ammonia nitrogen, and total nitrogen content of the waste water produced by the aerobic degradation food waste treatment plant are quite hig...
