Abstract

The invention discloses a treatment system and a treatment method of sticky substance flushing wastewater. The method specifically comprises the following steps: (1) introducing wastewater into a regulating tank for balanced regulation of water quality and water quantity; (2) stably introducing the wastewater regulated by the regulating tank into a demulsification tank, adding a demulsifier into the demulsification tank to carry out demulsification reaction, and adding a flocculation precipitator into the demulsification tank after the demulsification reaction to accelerate liquid layering; (3) carrying out demulsification and flocculent precipitation to obtain layered liquid, and introducing the supernatant liquid into an aerobic tank to carry out aerobic treatment; and (4) introducing the wastewater subjected to aerobic treatment into an ozone tank filled with an ozone catalytic filler, and discharging the water after being treated by the ozone tank after reaching the standard.

Description

technical field [0001] The present invention relates to a treatment system for sticky matter flushing waste water, and also relates to a treatment method of the above-mentioned treatment system. Background technique [0002] After the paint is made into finished products, it is stored in the tank, and then moved into the tank tank of the tanker for transportation. Due to the certain viscosity of the paint, a certain amount of finished paint is stuck to the wall of the stored tank. When the tank is rinsed with water, a kind of flushing wastewater will be formed. The wastewater is milky and has a high solid content, which seriously pollutes the environment. The main pollutants for COD, NH 3 -N and SS etc. Due to the high solid content, large amount of pollutants, and poor fluidity of the wastewater, coagulation-anaerobic-aerobic method is generally used in the treatment of similar wastewater. The process includes: regulating tank, coagulation sedimentation tank, anaerobic hy...
