Environment-friendly sewage treatment equipment capable of being circularly utilized

Abstract

The invention discloses environment-friendly sewage treatment equipment capable of being circularly utilized. The environment-friendly sewage treatment equipment comprises a No. 2 sedimentation tank and a purification groove, wherein a No. 1 sedimentation tank is arranged at one side of the No. 2 sedimentation tank; an electrolytic tank is arranged at the other side of the No. 2 sedimentation tank; a filtering screen is arranged on an inner surface of the No. 1 sedimentation tank; an activated carbon layer is arranged below the filtering screen; a pipeline is arranged at the other side of theNo. 1 sedimentation tank; a stirrer is arranged on the inner surface of the No. 2 sedimentation tank; a No. 2 waste dreg opening is formed below the No. 2 sedimentation tank. The environment-friendlysewage treatment equipment capable of being circularly utilized, disclosed by the invention, is provided with an anticorrosion coating, the filtering screen and a solar cell panel, and can be used forpreventing the pipeline from being corroded, so that the service life of the equipment is prolonged; the filtering screen also can detached to clean impurities, and electric energy produced by the solar cell panel can be used for carrying out electrolysis and deposition on sewage, so that energy saving and environment protection are realized; the equipment is applicable to different working conditions and brings a better application prospect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device with environmental protection and recyclability. Background technique [0002] Sewage, usually refers to the effluent from living and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants in sewage are pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. From the point of view of the source of sewage, sewage can be defined as waste-laden liquid or water mixed with groundwater, surface water, snowstorms, etc., discharged from residential, institutional, commercial or industrial areas. There are many types of sewage, and there are many technologies and processes to reduce the impact of sewage on the environment accordingly. [0003] The existing sewage treatment equipment has certain drawbacks in use. First, the pipeline ...

AI Technical Summary

Problems solved by technology

[0003] The existing sewage treatment equipment has certain disadvantages in use. Firstly, after a long time of use, the pipeline is prone to corrosion damage, which leads to the failure of normal use of the equipment. Secondly, it consumes a lot of energy and needs to provide a lot of working power. Fossil fuels have a short service life and are easy to block pipes, which has a certain impact on the use of sewage treatment equipment. Therefore, we propose an environmentally friendly and recyclable sewage treatment equipment
