摘　　要：采用接触氧化与日本自然循环方式污水处理技术相结合的流程,在进水COD、BOD5和NH3-N分别为209～408mg/L、52～80mg/L和15.3～24.6mg/L的条件下,去除率分别达到88%～93%、96%～97%、98%,出水稳定在COD≈30mg/L、BOD5≤4mg/L、NH3-N≤0.5mg/L的水平,SS未检出,以上指标达到国家地表水环境质量IV类标准(GB3838-2002)。An advanced sewage treatment project was presented. Through combining contact oxygen process with natural circulation wastewater treatment system from Japan, the removal efficiency of COD.BOD5 and NH3-N reached 88%-93% .96%-97% .98% respectively under the condition of influent concentration around 209-408mg/L、52 -80 mg/L and 15.3 -24.6 mg/L. The effluent concentration of COD、BOD5 and NH3-N was about 30mg/L.BOD5≤4 mg/L .NH3N≤ 0.5 mg/L respectively. SS was not detectable. The water quality had reached Environmental Quality Standards for surface water （IV）.
