一般污水在回收利用之前都要经过三级处理,即除渣、除油和去除微生物。由于生活污水中含有大量的固体废弃物、油类污染物和有害的化学成分,设计了一套污水处理系统,包括明渠除渣、平流隔油池、SBR反应池和过滤器4个子系统,经过上述4个子系统处理的水可以满足回收利用的要求。污水经过处理后可排放到清水池中实现再利用。整个系统的工艺流程如图1所示。
The general sewage must undergo three levels of treatment before recycling, that is, deslagging, degreasing and removal of microorganisms. Due to the large amount of solid waste, oil pollutants and harmful chemical components in domestic sewage, a set of sewage treatment system was designed including four sub-systems of open channel deslagging, horizontal flow grease trap, SBR reaction tank and filter The above four subsystems to deal with the water can meet the recycling requirements. Sewage can be discharged to clean water tank for reuse after treatment. The entire system of the process shown in Figure 1.
