摘要：

化学混凝—UASB—MUSB联合工艺处理低浓度生活污水主要包括常温条件下UASB反应器的启动运行，化学混凝对UASB处理效果的影响以及厌氧后处理工艺—MUSB工艺的运行状况三部分。结果表明该工艺具有停留时间短、能耗低、混凝剂用量少、供气量小、剩余污泥少等特点，是适应我国目前经济水平的污水处理工艺。

Abstract:

A process of chemical coagulation, UASB and MUSB reactor is for the treatment of low concentration domestic sewage. It is about the start-up operation and granular sludge formation of UASB reactor at ambient temperature, how chemical coagulation affects the treatment efficiency of UASB reactor, and the operation of anaerobic post-treatment MUSB reactor. The distinguishing characteristic of this process is lowcost because HRT is short, energy consumption is low, quantity of using coagulation is small, and quantity of supplying oxygen and producing excess sludge is also little. So the process is one of the sewage treatment technologies, which is suitable for the economy level of our country.

Key words: chemical coagulation, upflow anaerobic sludge blanket, domestic sewage
