Background
Engine developers have now designed exhaust gas recirculation systems for the purposes of improving diesel engine performance and reducing diesel engine exhaust emissions. Wherein, the working process of the exhaust gas recirculation system is as follows: fresh water is used for washing before the exhaust gas is circularly input into the cylinder, so as to reduce the temperature of the flue gas and remove particulate matters in the flue gas. The waste water after washing contains SOx, NOx, oil and particulate matters in the waste gas, so that waste water which is acidic, contains oil and has high turbidity is formed. Because the waste gas washing water is used in a closed circulation system, the waste gas washing water needs to keep a certain overflow amount, so that the surplus moisture condensed by the waste gas due to temperature reduction can be discharged, and the increase of the concentration of oil and particulate matters in the circulating water can be limited.

The principle is that gas is introduced into a dissolved air tank, a large amount of tiny bubbles are generated in water, so that air is attached to suspended particles in the form of highly dispersed tiny bubbles, and the suspended particles float on the surface by utilizing the buoyancy principle, thereby realizing solid-liquid separation. In general, the degreasing efficiency can reach more than 90%. The dissolved air tank is widely applied to the fields of domestic sewage, industrial wastewater, agricultural sewage and the like, and plays a role in purifying water quality. According to different treatment processes, the dissolved air tanks can be divided into a hollow fiber membrane dissolved air system, a fixed aerobic aeration system, an aeration deep tank system and the like.
The dissolved air tank is one of the essential key equipment in sewage treatment, has a vital effect on improving water quality and reducing pollution to the environment, and is unfavorable for the subsequent treatment of sewage because tiny bubbles can be attached to suspended particles in the process of impurity treatment by introducing gas into the dissolved air tank and then the suspended particles can be attached to the inner wall of the dissolved air tank after long-time use.
