Abstract

The biochemical reactor for treating sewage features that it is provided with aerobic area with aerobic apparatus in the upper part, deposition area, and separator and opening between the aerobic area and the deposition area. The oxidizing liquid has relatively high oxidizing rate with the oxygen utilizing rate reaching 40-50 %. The reactor has great volume load and short hydraulic retention period, may be operated in active sludge mode, and has simple structure, low capital construction cost, high solid-liquid separating effect and less residual sludge. The mixed sewage has compact microbe colony grains with excellent deposition performance.

Description

Technical field: [0001] The invention relates to the technical field of sewage biological treatment devices, in particular to a high-efficiency reactor for biochemical treatment in one step. Background technique: [0002] my country is a country that lacks water resources. The total amount is insufficient and the distribution is uneven in time and space. Especially in recent years, with the rapid development of the national economy, water pollution has become increasingly serious, which has exacerbated the contradiction of water shortage. According to statistics, in 1999, the total discharge of industrial and urban domestic wastewater was 40.1 billion tons, of which 19.7 billion tons were industrial wastewater and 20.4 billion tons were domestic sewage. The total discharge of chemical oxygen demand (COD) in wastewater was 13.89 million tons, of which 6.92 million tons were discharged from industrial wastewater and 6.97 million tons were discharged from domestic wastewater. ...
