The present research situation of avermectin waste water in China was introduced，the technology can be classified as preliminary purification and advanced treatment, the principle of the methods including electrolysis, coagulation,USAB, Fenton and adsorption-oxidation were analyzed in brief. Because there were lots of methods in treating the avermection waste water, which essentially could made the water reach the standards, the best method and parameters were obtained through depending on the experiments and techno-economic verification with the waste water situation.
