Abstract: By the introduction of Japanese wastewater treatment facility——Johkaso, the modeling technology was developed for the application of dispersed domestic wastewater to Tai Lake basin. The study indicated that Johkaso with the process of anaerobic filter bed-contacting aeration had functions to reduce organics，nitrogen and phosphor. Under the normal running condition，the designed discharge water objective, BOD≤10 mg/L，TN≤10 mg/L，TP≤1 mg/L could be reached.
