Air-flotation sewage treatment system

Abstract

The invention provides an air-flotation sewage treatment system. The air-flotation sewage treatment system comprises an air-flotation machine and a control device, wherein the air-flotation machine comprises an air-flotation groove, a drug-storage box, multiple sections of reaction grooves, a dissolved gas pump and a slag-scrapping machine; the drug-storage box is used for storing drugs; the multiple sections of reaction grooves are connected with the drug-storage box and are provided with a drug inlet for containing the drugs and a sewage holding port for holding sewage; the dissolved gas pump is provided with a gas inlet, a water inlet and a gas-liquid mixed outlet; and the water inlet and the gas-liquid mixed outlet are communicated with the air-flotation groove; the slag-scrapping machine is arranged above the air-flotation groove; and the control device is connected with the air-flotation groove, the drug-storage box, the multiple sections of reaction grooves, the dissolved gas pump and the slag-scrapping machine and is used for controlling the opening and the closing of the air-flotation groove, the drug-storage box, the multiple sections of reaction grooves, the dissolved gas pump and the slag-scrapping machine. By the air-flotation sewage treatment system, the efficiency of the sewage treatment can be improved, and the labor force can be saved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an air flotation sewage treatment system. Background technique [0002] In the prior art, an air flotation device is usually used when treating sewage, which mainly includes an air flotation tank and a bubble generating device. The bubble generating device has a pressurized air-dissolving chamber, which is respectively connected to provide The air compressor for the air, the booster pump that provides the liquid flow for it, the air compressor and the booster pump inject the air flow and the liquid flow into the pressurized air-dissolving chamber respectively, and carry out gas-liquid mixing and dissolving in the pressurized air-dissolving chamber After the gas-liquid mixed flow is formed, it is sent to the air flotation tank. In this method, the equipment release is relatively scattered, takes up a large space, and is difficult to manage and maintain. [0003] In view of this, h...
