The high-concentration organic wastewater in this paper takes landfill leachate as the experimental object, and takes corresponding measures to reduce the concentration of suspended solids as much as possible, so as to ensure the reliable operation of the subsequent treatment process. In the process of the experiment, it is necessary to simulate the process of mixing liquid in the reaction tank and blowing off the water, and remove the suspended substances in the reaction tank by centrifugal separation method. In this process, the influence of factors such as centrifugal time and rotational speed on the centrifugal effect is studied, and the corresponding centrifugal effect is determined when the conditions are different, and then the subsequent pretreatment and other processes are better carried out.展开更多
