At present, the oilfield sewage treatment in remote substation remained in the septic tank simple biological treatment stages. This water contains large amounts of organic matter, ammonia nitrogen, phosphorus and other substances which could cause destruction of water balance. To solve these problems, micro-integration of sewage treatment process was developed. By using Q bio-disc method, one of the sewage treatment plant integrated with domestic sewage treatment was built. Processed by the device, a substation of sewage water quality objectives can be achieved:COD 52 mg/L,and BOD5 515 mg/L,and SS 11 mg/L, and NH3-N 12 mg/L, and TP 0.6 mg/L, and TN 16mg/L, meet the GB18918-2002 class 1,B emission standard which State Environmental Protection Agency issued.%目前，油田边远变电所的生活污水处理一直停留在化粪池简单生化处理的阶段。这种污水含有大量有机物、氨氮和磷等物质，破坏水体生态平衡。针对此问题，开发研制了一种微型的生活污水一体化处理装置。该装置采用Q生物转盘法，集成了生活污水各个处理功能于一体。经该装置处理后，某变电所生活污水水质指标COD、BOD5、SS、NH3-N、TP、TN可降到52、515、11、12、0.6、16 mg/L，达到了国家标准（GB 18918—2002）一级B排放标准。
