Abstract

The invention discloses an environment-friendly sewage treatment device, and belongs to the technical field of sewage treatment, the environment-friendly sewage treatment device comprises an anaerobic treatment system and an aerobic treatment system, a gas supply mechanism is arranged between the anaerobic treatment system and the aerobic treatment system, the anaerobic treatment system comprises an anaerobic treatment tank, a water distribution pipe and a three-phase separator, the water distribution pipe is arranged at the bottom of the inner cavity of the anaerobic treatment tank, and the three-phase separator is arranged at the upper end of the inner cavity of the anaerobic treatment tank. Methane generated by anaerobic biological treatment is fully utilized as power to drive a water pumping mechanism to operate, sewage is pumped through the water pumping mechanism, energy is saved, and the gas supply mechanism is arranged, methane generated by anaerobic biological treatment is directly combusted to drive an external combustion engine to operate, so that a centrifugal fan is driven to aerate the inner cavity of the aerobic treatment tank, additional energy is not needed, methane which is inconvenient to store is effectively utilized, energy consumed by operation of an aerobic treatment system is greatly reduced, economic benefits are improved, and the device is more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an environment-friendly sewage treatment device. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering And other fields, more and more into the daily life of ordinary people. [0003] Existing sewage treatment devices generally purify sewage through chemical methods. Although the use of chemical preparations can purify sewage to a certain extent, it is not environmentally friendly and sustainable, so the use of microbial life Activities to metabolize the organic matter in wastewater, so as to achieve the purpose of sewage biochemical treatment technology has be...
