Sewage purification device with dry-wet separation mechanism

Abstract

The invention relates to the field of water treatment equipment, and discloses a sewage purification device with a dry-wet separation mechanism. The sewage purification device comprises a purification chamber, wherein a water inlet is arranged at the top of the purification chamber, a water storage tank is arranged below the water inlet, the dry-wet separation mechanism is arranged between the water storage tank and the water inlet, and the dry-wet separation mechanism comprises a first-stage dry-wet separation assembly and a second-stage dry-wet separation assembly. According to the invention, sewage flows into the water storage tank after being separated by the first-stage dry-wet separation assembly and the second-stage dry-wet separation assembly; the water storage tank is sequentially connected with an anaerobic tank, an aeration tank and a sedimentation tank; the anaerobic tank is used for anaerobic treatment of the sewage; the aeration tank is used for aerobic treatment of the sewage; the sedimentation tank is used for sewage impurity sedimentation treatment, and the sedimentation tank is connected with an ultrafiltration membrane filter; a water guide pump is arranged between the sedimentation tank and the ultrafiltration membrane filter; the ultrafiltration membrane filter is used for intercepting macromolecular impurities; a sewage discharge end of the ultrafiltration membrane filter is used for discharging concentrated water with intercepted substances; and the water outlet end of the ultrafiltration membrane filter is used for discharging filtered water.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a sewage purification device with a dry-wet separation mechanism. Background technique [0002] Sewage refers to the water body that is polluted by people in the process of using water in production and life. Therefore, sewage contains a large amount of pollutants, which will cause damage to the natural environment. Therefore, sewage cannot be directly discharged into the natural environment. , and the equipment or devices that often treat sewage are called sewage treatment equipment. Sewage treatment equipment can effectively treat urban domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from directly flowing into water areas, which is beneficial to improving the ecological environment, improving urban quality and promoting urbanization. Economic development is of great significance. [0003] According to the classification of sewage sources...
