In this paper, experimental study of the hydraulic loading, organic loading, recharge times and C / N ratio of concentrate recirculation effect. Also studied concentrate recharge effluent COD of the "lag" phenomenon and the secondary effects of recharge. The experimental results show that with the hydraulic loading increases, the concentrated liquid removal rate of COD reduced recharge. Organic load in a certain range, COD removal rate of recharge concentrate the increase of the concentration, in the case of high organic load, COD removal rate will decline. An increasing number of beneficial recharge COD removal efficiency increased, but the number of times within a day should not be more than six times recharge. As the C / N rate increases, COD removal was significantly improved. Concentrate recharge to junk level, the effluent COD concentration has a first increased and then decreased in the process, that there is "lag" phenomenon. There is still some secondary recharge on COD removal efficiency, can be recycled many times to effectively deal with the concentrate.
