摘　　要：晋中市某污水处理厂扩建及再生水回用工程处理规模为10×10^(4) m^(3)/d,其中污泥低温碳化工程规模为100 t/d,粪便处理工程规模为140 m^(3)/d,再生水回用工程规模为8×10^(4) m^(3)/d。污水处理采用多模式改良AAO+混凝沉淀+过滤工艺,污泥处理采用重力浓缩+污泥低温碳化+机械脱水工艺,污泥含水率≤40%;粪便处理采用机械脱水工艺。设计出水水质执行地表水准Ⅴ类标准,碳化污泥作为焚烧炉燃料。实际运行结果表明,该工程出水水质可稳定达标,污水处理单位经营成本为0.78元/m^(3),吨水能耗均值约0.42 kW·h/m^(3),再生水经营成本为1.32元/m^(3),污泥碳化处理单位经营成本为202元/t,粪便协同处置经营成本为77.65元/m^(3)。The capacity of a sewage treatment plant expansion and reclaimed water reuse project in Jinzhong is 10×10^(4) m^(3)/d,consisting of 100 t/d of low temperature sludge carbonization project,140 m^(3)/d of feces treatment project,and 8×10^(4) m^(3)/d of the reclaimed water reuse project.The multi‑mode improvement AAO,coagulation sedimentation,filtration process is adopted for sewage treatment,and the gravity concentration,low temperature sludge carbonization,and mechanical dehydration process is adopted for sludge treatment with sludge water content no more than 40%.The manure is treated by mechanical dewatering process.The effluent quality is designed to meet levelⅤin Environmental Quality Standard for Surface Water(GB 3838-2002),and the carbonized sludge is used as the fuel of the incinerator.The actual operation results show that the effluent quality can satisfy the criteria stably.The unit operating cost of sewage treatment is 0.78 yuan/m^(3) and the average energy consumption is about 0.42 kW·h/m^(3).The operating cost of reclaimed water is 1.32 yuan/m^(3).The unit operating cost of sludge carbonization treatment is 202 yuan/t.The feces collaborative disposal cost is 77.65 yuan/m^(3).
