The sewage flows from pool to plant, passing through retention reservoir to adjust PH value, into removing ammonia with temperature increasing to 20℃,into UASB reactor with temperature increasingto 35℃ to remove off COD and ammonia under the function of anaerobia, then into SBR reactor to remove BOD under the function of aerobia. When the biochemical disposal is completed, the processed sewage will come into the UF system to remove adsorbed solid, organic matter, bacteria, and pathogens in waterand finally come into the RO system to remove off dissolvable salinity, colloid, organic matter, and microbe in water.

The traditional Passveer single ditch and Carrousel ditch are not good at removable N and P, but in the front of anaerobic pond is intercalated, and anoxic area is intercalated in, Carrousel Oxide Ditch becomes a mendable Carrousel 2000 Oxidation Ditch, so it possesses removal removal nitrogen and phosphorus by biology function.

传统的Passveer单沟型和Carrousel型氧化沟脱氮除磷功能差，但是在Carrousel氧化沟前增设厌氧池，在沟体内增设缺氧区，形成改良型Carrousel 2000氧化沟，便具备生物脱氮除磷功能。

As to these problems, a novel MBR named internal circulation membrane bioreactor is developed, in which the aeration not only supplies the required oxygen, but is utilized for the circulation of nitrified wastewater. It carries out the nitrogen and carbon removal of domestic wastewater in a single treatment unit. Simulated domestic wastewater is used in this research.
