Problems solved by technology

Most of these methods have the characteristics of long residence time, poor treatment effect in winter, and poor removal effect of nitrogen and phosphorus in wastewater.
Therefore, the lack of existing rural domestic sewage treatment technology and the large discharge of nitrogen and phosphorus are the direct causes of serious eutrophication in domestic water bodies

Abstract

The invention discloses a solar rural domestic sewage treating device and a technique thereof. The solar rural domestic sewage treating device comprises a sewage anaerobe treating tank, a facultativeaerobe treating tank, a solar aeration system and a sludge return system, wherein the solar aeration system consists of a solar panel, a storage battery, an aeration machine and an aeration pipe. Thesewage to be treated automatically flows into the anaerobe treating tank hung with fillers from a water inlet, then is discharged after being treated, then reflows into the facultative aerobe treatingtank equipped with the solar aeration pipe, is discharged after being treated, is precipitated by a secondary precipitation tank and then is discharged. The solar panel collects and converts solar energy into electric energy which is stored in the storage battery, and drives the aeration machine to aerate for the facultative aerobe treating tank by the storage battery; and simultaneously, a sludge return pump of the secondary precipitation tank provides energy by the storage battery and carries out sludge returning. Therefore, the invention not only effectively utilizes natural energies, butalso reduces operating cost, improves the degree of the rural domestic sewage treatment and provides a novel rural domestic sewage treating technique.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a solar-powered rural domestic sewage treatment device and a process thereof. Background technique [0002] Rural domestic sewage is a type of sewage with a large amount and a wide range. In recent years, with the development of towns and villages in our country and the rapid improvement of the living standards of the majority of rural people, the discharge of rural domestic sewage has continued to increase, making rural non-point source pollution increasingly serious. , presenting a trend of pollution shifting from urban to rural areas. [0003] Among the existing methods of decentralized domestic sewage treatment in rural areas, there are mainly unpowered anaerobic biological treatment, land treatment, artificial wetland and other processes. Most of these methods have the characteristics of long residence time, poor treatment effect in winter, and poor removal effect of nitrogen and...
