Description

Domestic sewage centralized treatment device Technical Field The utility model relates to the technical field of sewage treatment, in particular to a domestic sewage centralized treatment device. Background With the further enhancement of new rural construction, the centralized treatment and discharge of rural sewage becomes a new problem. In rural areas, the sewage mainly takes domestic sewage as main material, and the domestic sewage is directly discharged into streams and river channels without treatment, so that the water quality and the environmental landscape are seriously influenced. There is thus a need for a domestic sewage centralized treatment device that addresses the above-described problems. In the prior art, application number CN201821117775.7 discloses a domestic sewage centralized treatment device, the injected sewage is stirred and mixed with a flocculating agent in a stirring cavity, sewage precipitation is promoted by stirring uniformly, in addition, a cleaning water pipe is arranged, a water pump can convey water in a water storage cavity to the cleaning water pipe, and the water pump sprays water from a spray head to back wash an inclined tube settler, so that the cleaning operation is convenient. But above-mentioned domestic sewage centralized processing device adopts the mode of filter screen to filter at its water inlet, can cause the water inlet to block up for a long time, consequently need often clear up the filter screen of water inlet, and the built-in filter core material is changed inconveniently, long-time after using, and filter effect greatly reduced influences quality of water, consequently improves it to above-mentioned problem. Disclosure of utility model This section is intended to outline some aspects of embodiments of the utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section as well as in the description of the utility model and in the title of the utility model, which may not be used to limit the scope of the utility model.
