摘　　要：加压生物接触氧化法通过简单的“加压”方式有效提高了污染物去除率。处理生活污水的试验表明 ,当压力为 0 2MPa ,停留时间为 0 8h ,气水比为 (3～ 4 )∶1时 ,处理出水的COD ,BOD ,SS等污染物浓度可达到一级排放标准。与常压法相比 ,污染物去除率提高了 10 %～ 18% ,停留时间仅为常规生物处理法的 1/ 3～ 1/ 4。因此 ,该法具有处理效果好、处理时间短、占地少、适用性强、耐冲击负荷的特点 ,特别适合城镇小区生活污水处理成套设施的建设。The pressure biological contact oxidation process (PBCO) can effectively increase the pollutant removal efficiency by simple pressurized way. Experimental research was conducted for domestic wastewater treatment under condition of pressure 0 2 MPa, retention time 0 8 hour and air/wastewater ratio 3～4∶l. The results show that the major pollutant residues such as COD, BOD and SS in effluent were very low, and quite good to meet the requirement of grade I in the national wastewater discharge standards. Comparing with atmospheric process, the removal efficiency rises l0%～18%, and the retention time reduced to only 1/3～1/4 of the former. The PBCO has advantages of high treatment efficiency, low retention time and smaller space demand. And it is very suitable and compatible for the wasterwater treatment of residential quarters or small townships.
