Abstract

The invention discloses an underground type sewage treatment device. The underground type sewage treatment device consists of a grating well, an adjusting tank, an anaerobic tank, an aerobiotic tank, a settling tank, a filter tank and a clear water tank. Outlet water of the settling tank is filtered by the filtering tank, and therefore, COD (Chemical Oxygen Demand) and SS (Sulfur) of the outlet water are obviously lowered; a back-flushing water pump and a back-flushing control valve are arranged in the clear water tank; a valve does not need to be manually operated for back-flushing of the filter tank, so that the underground type sewage treatment device is simple to operate, and can be integrally buried underground without being managed by a specially-assigned person.

Description

technical field

[0001] The invention relates to an underground sewage treatment equipment. Background technique

[0002] With the increase of urban population and the development of industrial and agricultural production, the sewage produced in the production and living process is also increasing. In order to reduce the harm of sewage to water bodies and the environment, it needs to be purified before it is discharged into the environment. links.

[0003] Most of the existing sewage treatment systems are composed of pretreatment system, biochemical treatment system and mud-water separation system. Although the treated sewage can meet the water quality requirements of sewage, with the improvement of environmental protection requirements, the existing To improve the sewage treatment system, generally add a quartz sand filter behind the buried sewage treatment equipment to improve the effluent standard. Now these two parts are generally separated and independent. Due to struct...
