摘要: 针对传统生活污水水质相对复杂,处理与回用较为困难的问题,提出在收集时排除粪便水,选择厨房、洗漱、洗澡、洗涤的污水,利用浸没式膜生物反应器(SMBR)技术实现无粪便污水的快速处理,再生水回用于冲厕。结果表明:此种污水COD、NH4+-N和TP含量低,具有良好的可生化性,可大大降低处理周期与处理成本。本技术优化的主要工艺条件为:污泥浓度范围7000~9100 mg·L-1,污泥龄(SRT)40~55 d,水力停留时间(HRT)为80 min,气水比为12~15,处理效果好,微滤膜对稳定出水水质起到重要作用。在此条件下,COD、NH4+-N和TP去除率分别为85.5%、53.1%和44.9%。出水COD在20~30 mg·L-1,BOD5为1~5 mg·L-1,NH4+-N为2~3.08 mg·L-1,TP为0.59~0.9 mg·L-1,LAS为0.41~0.67 mg·L-1,去除效果较好,再生水水质可达到《城市污水再生利用城市杂用水水质》(GB/T 18920-2002)标准。

Abstract: Aiming at the relative complexity of conventional domestic sewage water and the difficulties in treating and recycling this kind of water, an advanced treatment of domestic wastewater drained from kitchen, shower, and rinse but not from lavatory was processed. By adjusting the hydraulic retention time (HRT) and the aeration amount of submerged membrane bioreactor (SMBR), a set of feasible option of technical parameters was determined to keep the system in steady-state. When the treatment was conducted under the optimum operation conditions of HRT 80 minute and air/water ratio 12-15, MLSS  7000-9100 mg·L-1, and solid retention time (SRT)  about 40-55 d, the removal rate of COD, NH4+-N, and total P was 85.5%, 53.1%, and 44.9%, and the COD, BOD5, NH4+-N, total P, and LAS of effluent water were 20-30 mg·L-1, 1-5 mg·L-1, 2-3.08 mg·L-1, 0.59-0.9 mg·L-1, and 0.41-0.67 mg·L-1, respectively, meeting the National Standards for Recycling
