Abstract

The invention discloses a domestic sewage treatment system. The system comprises an artificial grill a mechanical grill, an oil-separation and sedimentation tank, a regulation and hydrolysis tank, anair floatation device, an anaerobic internal circulation reactor, an aerobic reaction tank, an intermediate tank, a filtration system, a disinfection device, a sludge thickening tank and a biogas power generation device, the input end of the aerobic reaction tank is connected with a blower, the output end of the aerobic reaction tank is connected with a sludge dewatering tank through the sludge thickening tank, the biogas power generation device includes a desulfurization tower, a gas cabinet and a biogas power generator, and the output end of the anaerobic internal circulation reactor is sequentially connected with the biogas power generator through the desulfurization tower and the gas cabinet. The domestic sewage treatment system has the advantages of simple structure, easiness in use,and realization of good purification of slaughter wastewater; and biogas produced by the anaerobic internal circulation reactor generates power after passing through the desulfurization tower, the gascabinet and the biogas power generator in order to generate a large amount of electric energy, and an electric control system powers the electric devices of the domestic sewage treatment system in order to produce significant economic benefits while treating the wastewater.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a domestic sewage treatment system. Background technique [0002] The proportion of domestic wastewater discharge in the total wastewater discharge is relatively large. With the improvement of people's living standards and the reduction of resources, the requirements for sewage treatment are higher, especially the slaughter wastewater comes from the slaughtering and processing of livestock and poultry, which is the largest in my country. One of the sources of organic pollution. Its domestic wastewater and slaughter wastewater have a high content of organic pollutants. Such as COD2500-3500mg / L, BOD 5 1500-2000mg / L, SS1000mg / L. BOD 5 / COD≥0.5; biodegradability is good, non-toxic, BOD / COD is greater than 0.6; the wastewater contains a lot of residues, etc., and the content of suspended solids is high; the content of N and P in the wastewater is high. According to th...
