摘　　要：对日光型厌氧好氧一体化技术处理农村生活污水的效能进行了应用研究。系统的处理量为89t/d,HRT为1.8 d,水解酸化段水力负荷为0.78 m3/(m3·d),接触氧化段水力负荷4.24 m3/(m3·d),稳定运行6个月结果表明:该工艺对CODcr、NH3-N 、TP和SS的去除率分别为73.2%、49.5%、56.1%和79.3%,出水 CODcr、NH3-N、TP、SS的平均浓度分别在60.3 mg/L、20.4 mg/L、2.7 mg/L、26.7 mg/L以下出水水质达到GB18918-2002要求。In this study, a solar anaerobic-aerobic integrated bio-technique was used for the treatment of the rural domestic sewage. Currently, the treating capacity of the station was 89 t/d, with the hydraulic retention time（HRT） of 1.8d, and the hydraulic loads in the hydrolysis acidification stage and the contact oxidation stage were 0.78 m^3/（m^3 · d） and 4.24 m^3/（m^3· d）, respectively. The treating station kept on working stably for over six months. The results showed that the removal rates of COl）c,, NH3-N, TP and SS were 73.2%, 49.5%, 56.1% and 79.3%, respectively. The average effluent concentrations of COl）c,, NH3-N, TP and SS were under 60.3rag/L, 20.4mg/L, 2.7mg/L, 26.7mg/L, respectively. The effluent quality of the station could meet the requirements of GB 18918-2002.
