摘要
本中试试验结果表明:一体式好氧中空纤维膜-生物反应器处理生活污水用于回用在技术和经济上都是可行的。在不人为排泥的条件下,该系统连续运行110多天没有洗膜。系统出水稳定优质(COD<30mg/L,NH3-N<10mg/L,无色无味透明,未检出大肠杆菌);基建费用低,运行费用和传统污水深度处理工艺相差不多。空曝气和在线药洗是进行膜日常维护的有效方法。
Abstract The technical and economical feasibility of integral membrane bio reactor (IMB) to treat domestic wastewater for reuse has been approved by the results of a pilot plant experiment. The pilot plant ran continuously over 110 days without membrane rinsing and no sludge discharge. The output water is quite stable and high quality with COD<30mg/L and NH 3-N<1.0mg/L respectively, it seems transparent and free of color and smell, and no coliform was detected. For the IMB facility the investment is lower than and the operation expense is similar to the traditional advanced treatment. Air blow and on line chemical rinsing is effective for the routine maintenance of the IMB. The membrane rinsing cycle is heavy effected by the condition of water circulating inside the reactor and the operating at the starting stage.
