Culture sewage treatment process

Abstract

The invention relates to the field of sewage treatment, in particular to a culture sewage treatment process. The culture sewage treatment process comprises the following steps of S1, feeding culture sewage into a marsh gas tank; S2, feeding the culture sewage into a regulating tank through self flowing via the marsh gas tank; S3, conveying the regulated culture sewage to a precipitation tank; S4,feeding the culture sewage into an ozone aeration tank after passing through the precipitation tank; S5, feeding the culture sewage subjected to ozone aeration into a two-stage A / O biochemical integral tank for treatment; S6, passing the culture sewage passing through the two-stage A / O biochemical integral tank through a sand filtering tank, a clean water tank, an artificial wetland system and a clean water tank, and then directly discharging the sewage. The low-load active sludge process is used; the CODCr and BOD5 can be effectively degraded by a biochemical treatment method; the characteristics of compact ground occupation, stable process, low investment, simple maintenance, low operation cost and the like are realized.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a breeding sewage treatment process. Background technique [0002] The livestock and poultry breeding industry is a leading industry in my country's agriculture, and the pollution from livestock and poultry breeding has become one of the main causes of rural non-point source pollution in my country. With the rapid development of livestock and poultry production, especially the development of large-scale breeding, a large amount of livestock excrement and various wastes are produced, causing the contradiction between the development of livestock and poultry industry and environmental pollution to become increasingly prominent. Due to the excretion of livestock, especially the use of a large amount of feed at this stage, a large amount of pollutants are contained in livestock manure, which eventually leads to a serious over-high of biochemical indicators in sewage. At present, acco...
