Sewage efficient treatment equipment

Abstract

The invention discloses sewage efficient treatment equipment, which comprises a machine body and an ultrasonic generation device, wherein the top end of the machine body is provided with an upper cover; a water inlet pipe is arranged on the upper cover; a buffer box is arranged in the machine body; an aeration disc is arranged at the bottom end of the buffer box; a control valve is arranged on oneend of the water inlet pipe; the other end of the water inlet pipe sequentially passes through the upper cover, a membrane bioreactor, a filtering layer, a filling layer, an ultrasonic reaction layerand a buffer precipitation device to be arranged in the buffer box; an ultrasonic reaction device is arranged in the ultrasonic reaction layer, and comprises ultrasonic plates and two ultrasonic generators; the two ultrasonic plates are respectively and symmetrically arranged in the machine body; the ultrasonic generators are arranged outside the machine body; the two ultrasonic plates are electrically connected with the ultrasonic generators; the upper end of the machine body is provided with a water discharging pipe; one end of the water discharging pipe passes through the machine body to be arranged in the membrane bioreactor. The sewage efficient treatment equipment has the advantages that the structure is simple; organic pollutants can be catalyzed; the sewage is effectively purified; the precipitation is fast.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to high-efficiency sewage treatment equipment. Background technique [0002] For a long time, industrial sewage has been one of the problems restricting the rapid development of industry, and how to deal with industrial sewage is also a concern of everyone. Therefore, how to scientifically and rationally treat industrial sewage, recycle water resources and fibers, turn waste into treasure, and generate good economic benefits has always been a subject of hard work by experts at home and abroad. At present, the sewage treatment technology has basically taken shape, but the eutrophic oxidation of the water body caused by the excessive discharge of nitrogen and phosphorus is still a major problem in water pollution. The purpose of sewage treatment is not only to remove organic matter, but to remove both organic matter and Nitrogen and phosphorus removal, reducing eutrophic oxidation of wate...

Problems solved by technology

At present, the sewage treatment technology has basically taken shape, but the eutrophic oxidation of the water body caused by the excessive discharge of nitrogen and phosphorus is still a major problem in water pollution. The purpose of sewage treatment is not only to remove organic matter, but to remove both organic matter and Nitrogen and phosphorus removal, reducing eutrophic oxidation of water body

Existing sewage treatment devices generally use multiple sedimentation tanks to precipitate and separate denitrifying phosphorus-accumulating bacteria. There are many reactors, many steps, small effective volume of reactors, low efficiency, and inconvenient operation. And the use of ultrasonic catalysis technology has complex structure, low flexibility, high energy consumption, high cost, incomplete degradation, long particle precipitation time, and cannot achieve the purpose of rapid water recycling in the production process. When draining, part of the sludge will be discharged with the water flow , the separation effect is not good
