Abstract

The invention discloses an integrated sewage treatment device for unpowered reflowing. The device comprises an anaerobic zone, an anoxic zone, an aerobic zone and a precipitation zone which are orderly communicated, wherein the aerobic zone and the precipitation zone are arranged at the upper part of the sewage treatment device, the anaerobic zone and the anoxic zone are arranged at the lower part of the sewage treatment device; the upper part and the lower part are separated from each other through a horizontally arranged partition; the anoxic zone and the aerobic zone are communicated through an inside runner, the partition is provided with at least one flow-guiding open / close for connecting the anoxic zone and the aerobic zone; the mixed solution in the aerobic zone reflows to the anoxic zone to form the cyclic mixed solution through the flow-guiding open / close under the gravity effect when the flow-guiding open / close is in an open state; the mixed solution in the aerobic zone reflows to the anoxic zone only under the gravity effect through the flow-guiding open / close device by use of the sewage treatment device, the unpowered reflowing of the mixed solution is realized, and meanwhile, a denitrification path of the mixed solution can be regulated through the flow-guiding open / close device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an integrated sewage treatment device without power backflow. Background technique [0002] With the development of my country's economy and society, the crisis of water resources and the pollution of water environment are becoming more and more serious. The discharge of various types of sewage and wastewater has increased significantly, seriously endangering the water body environment. The treatment of water pollution has become one of the hot spots in the field of environmental protection at home and abroad. The sewage treatment mode is divided into centralized treatment mode and decentralized treatment mode. Among them, the urban sewage adopts the centralized treatment mode, and the integrated sewage treatment device adopts the flexible, simple and efficient decentralized treatment mode, which is more in line with the characteristics of rural sewage treatment...
