Integrated low energy consumption decentralized village and town domestic sewage treatment system

Abstract

The invention relates to an integrated low-energy-consumption distributed villages and small towns domestic sewage treatment system. The integrated low-energy-consumption distributed villages and small towns domestic sewage treatment system comprises an adjusting tank; the adjusting tank is communicated with a water inlet pipeline of a biological contact oxidation reaction tank through an adjusting tank elevator pump; the water inlet pipeline is arranged on the upper part of the biological contact oxidation reaction tank; the biological contact oxidation reaction tank is communicated with a sedimentation basin through a water inlet pipeline of the sedimentation basin; a water outlet of the sedimentation basin is communicated with a filter cloth filter tank through a water inlet pipeline ofthe filter cloth filter tank; the sedimentation basin is connected with a sludge tank and the biological contact oxidation reaction tank through a sedimentation basin sludge discharge device respectively; a water outlet of the filter cloth filter tank is communicated with a device water discharge pipeline; the device water discharge pipeline is provided with an ultraviolet disinfection device. The integrated low-energy-consumption distributed villages and small towns domestic sewage treatment system is excellent in water discharge effect, is high in impact load endurance, and low in energy consumption, and is convenient for installation.

Description

technical field [0001] The invention relates to an integrated low-energy-consumption decentralized village and town domestic sewage treatment system, which belongs to the field of sewage treatment equipment. Background technique [0002] With the continuous development of human society and the continuous expansion of urban scale, the water consumption and drainage of cities are increasing, which intensifies the tension of water use and the pollution of water quality. The resulting water crisis has become an important factor restricting social and economic development. . In recent years, with the development of the rural economy, the discharge of domestic sewage in rural areas has been increasing. According to relevant statistics, it is estimated that by 2020, the discharge of sewage in China's villages and towns will reach 27 billion tons, accounting for more than 50% of the national water pollution discharge. The growth rate exceeds 10%. In China, there are 20,515 towns, ...
