A solar sewage treatment device for decentralized rural domestic sewage treatment

Abstract

The invention relates to a solar sewage treatment device for decentralized rural domestic sewage treatment. It is characterized in that it includes a solar power supply system and a sewage treatment system. The sewage treatment system includes a pool body. One end of the pool body is provided with a water inlet pipe, and the other end is provided with a water outlet pipe. An anaerobic reaction zone is provided in the pool near the water inlet pipe. , an inclined drainage baffle is set in the anaerobic reaction zone, and an adjustment tube is arranged on one side of the drainage baffle, and one side of the adjustment tube is an electrode area, and a plurality of inclined electrode plates are installed in the electrode area, and the A gravity precipitation area is set on one side of the electrode area, and the solar power supply system supplies power to the electrode plate. Compared with existing systems, the present invention has the advantages of high energy utilization rate (no secondary conversion of energy form), no rotating parts, simple structure, easy maintenance and low cost.

Description

technical field [0001] The invention relates to a solar sewage treatment device for decentralized rural domestic sewage treatment. Background technique [0002] After years of continuous efforts, urban domestic sewage has basically been effectively collected and treated. However, for rural areas that are relatively scattered and have a large population flow, due to the poor economic feasibility of building sewage collection systems, centralized treatment systems The scope of application is relatively limited, and domestic sewage is often discharged directly without control. [0003] In response to this situation, researchers have proposed a single-family biochemical system that focuses on miniaturization, with buried and micro-power as the main features: such as aerobic and anaerobic filters, attachment growth systems represented by rotating discs, The advantages of a series of solutions such as the MBR system are that these technologies have been extensively tested in prac...

[0002] After years of continuous efforts, urban domestic sewage has basically been effectively collected and treated. However, for rural areas that are relatively scattered and have a large population flow, due to the poor economic feasibility of building sewage collection systems, centralized treatment systems The scope of application is relatively limited, and domestic sewage is often discharged directly without control

[0003] In response to this situation, researchers have proposed a single-family biochemical system that focuses on miniaturization, with buried and micro-power as the main features: such as aerobic and anaerobic filters, attachment growth systems represented by rotating discs, The advantages of a series of solutions such as the MBR system are that these technologies have been extensively tested in practice and have good reliability; however, the structure is complex and requires more professional operation and maintenance. After completion, most of them are in the On the other hand, the biochemical treatment unit will easily lead to changes in the number and activity of microorganisms when the water volume changes. Compared with the design, the biochemical efficiency is quite different. At the same time, taking the current popular micro-power system as an example, it still needs a certain amount of operation investment and professional maintenance (such as equipment maintenance, electricity bills, etc.), which also limits its further application.

It has also been reported in the literature that from the perspective of reducing maintenance costs, using solar energy to supply the energy needs of water pumps, fans, etc., thereby solving part of the energy costs, but the improvement of the inherent operating conditions of the biochemical system is small
