A high-efficiency aeration device that can clean up flocs

Abstract

The invention discloses an efficient aeration device capable of cleaning flocculate. The efficient aeration device comprises an aeration chamber, a moving plate, a support and a flocculate accumulation cavity, the support is fixedly mounted at the upper end of the aeration chamber, a motor is arranged on the inner side of the support, a threaded sleeve penetrates the upper end of the aeration chamber and is rotatably connected with the aeration chamber, the lower end of the threaded sleeve is in threaded connection with a screw, the other end of the screw is fixedly connected with the middle of the moving plate, and the moving plate is slidably connected with the aeration chamber; multiple water permeable holes are formed in the moving plate, a retaining plate is hinged at the upper ends of the inner sides of the water permeable holes, and the other end of the retaining plate is connected with the inner walls of the water permeable holes through a second spring; the flocculate accumulation cavity is arranged on the right side of the aeration cavity, and a water permeable film is arranged in the flocculate accumulation cavity. The efficient aeration device is reasonable in design, and sewage is intermittently delivered into the flocculate accumulation cavity for filtering through up-down movement of the moving plate, so that flocculate in the sewage in the aeration cavity is lowered, sewage treatment efficiency is improved, sewage treatment effect is enhanced, and the efficient aeration device is high in practicability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an efficient aeration device capable of cleaning flocs. Background technique [0002] The problem of water pollution is an environmental problem throughout the world. According to the methods used in sewage treatment, it can be divided into four types: physical method, chemical method, physical chemical method and biological method. Biological method is a method of using the metabolism of microorganisms in wastewater to decompose degradable organic matter in sewage. Because of its large processing capacity, low investment, and economical reliability, it has become the most common water treatment method in the world today. Among them, the aerobic biological method faces constraints such as aeration efficiency and the performance of the aeration device. In the treatment of urban domestic sewage and industrial wastewater, the aeration and oxygenation equipment used for biochemical t...

Problems solved by technology

When these flocs cannot be treated in time, it will hinder the contact between water and "micro-bubbles", which will affect the further flocculation of sewage and greatly slow down the flocculation speed.
