室温下厌氧膜生物反应器处理生活污水的运行特性
Operating characteristics of anaerobic membrane bioreactor for domestic wastewater treatment under ambient temperature
摘要
Abstract
A bench-scale anaerobic membrane bioreactor (AnMBR) was built for treating the actual domestic wastewater in order to make a step forward to improve the situation of sewage treatment and management from distributed region such as villages and small towns.The reactor operated for 288 days with the optimized HRT from 12 to 14 h under ambient temperature (18 to 37 ℃).The influent was taken from the regulating reservoir of a reclaim water treatment station and the water quality varied from day to day with the average concentration of TCOD(477 mg· L-1),NH3-N(69.1 mg· L-1),TN(76.9 mg· L-1),TP(6.3 mg· L-1) during whole operation time.From the start of 55th day,the average TCOD of effluent was less than 50 mg · L-1 and remained stable for the next 117 days.The average value of TCOD removal efficiency could be reached 90.6％ while the average VLR value of 0.83 kg · (m3 · d)-1 Although the AnMBR could achieve a very high COD removal efficiency,it had little effect on nitrogen and phosphorus removal.关键词
