I. INTRODUCTION Oxidation ditch technology is a new type of technology developed in the middle of this century. Because the oxidation ditch has a simple structure, simple operation and stable and reliable treatment effect, it is more and more important for water treatment scientific research and engineering technicians. In recent years, with the increasing emphasis on reducing water treatment energy consumption and improving treatment efficiency, the technology of oxidation ditch has been paid more attention by people. Therefore, it has been effective in application promotion and deepening of technology. At present, the oxidation ditch is widely used in the treatment of municipal sewage and various industrial waste water, and there are thousands of people around the world.
