摘　　要：采用高效集成生物反应器(HCR)处理生活污水,考察了水力停留时间、污泥回流比和射流量对污染物去除效果的影响。结果表明,在水力停留时间为90min,污泥回流比为120%和射流量为2.1m3/h的最佳运行条件下,HCR对COD、BOD5、NH3-N和SS的去除率分别为82.3%、93.5%、86.3%和93.1%,出水COD、BOD5、NH3-N和SS均达到《城镇污水处理厂污染物排放标准》(GB18918—2002)中一级B标准。High performance compact reactor（HCR） was used to treat domestic sewage, and the influence of hydraulic retention time, sludge return ratio and jet flux on the pollutant removal efficiency was investigated. The optimal operating conditions were obtained as follow： hydraulic retention time of 90 min, 120% of sludge return ratio and 2.1 m^3/h of jet flux. Under these conditions, the HCR process presented perfect performance on domestic sewage treat- ment with the removal rates of COD, BOD5, NH3-N and SS were 82. 3%, 93.5%, 86.3% and 93. 1 % respectively. The effluent concentration could achieve the first grade（B） of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB 18918--2002）.
