Sewage treatment equipment applicable to living sewage treatment of multiple families

Abstract

The invention discloses sewage treatment equipment applicable to living sewage treatment of multiple families. The sewage treatment equipment comprises an external tank, wherein an anaerobic zone, anaerobic zone, a settling zone, a sludge reduction zone and an equipment zone which are separated from one another are arranged inside the external tank; the anaerobic zone, the aerobic zone, the settling zone and the sludge reduction zone are sequentially communicated; the anaerobic zone is communicated with a septic tank; the aerobic zone is communicated with the anaerobic zone to flow back a part of a mixed liquid into the anaerobic zone; the settling zone is communicated with the anaerobic zone to flow back a part of activated sludge into the anaerobic zone; the sludge reduction zone is communicated with the anaerobic zone or the septic tank; a detection unit for detecting various parameters in the sewage treatment process and a controller for controlling working states of different sewage treatment devices of the sewage treatment equipment according to detection results of the detection unit are arranged in the equipment zone. The sewage treatment equipment is applicable to livingsewage treatment of multiple families, is stable in effluent quality, can be automatically adjusted, and plays roles of energy conservation and emission reduction.

Description

Technical field [0001] The present invention relates to the technical field of sewage treatment equipment, in particular, to a sewage treatment equipment suitable for the treatment of domestic sewage from multiple households. Background technique [0002] In recent years, the process of industrialization and urbanization in my country has accelerated, the adjustment of industrial layout and economic structure has been intensified, the human settlement environment supervision is weak, the policy is relatively lagging, and industrial pollution and urban life pollution have increased sharply. Although there are currently multi-household sewage treatment equipment installation plans on the market for areas that are not covered by the municipal sewage collection pipe network, there are problems such as large volume, low effluent index compliance rate, and poor promotion. In fact, it is difficult to achieve multi-household sewage. The comprehensive treatment. In addition, the existing...
