摘要
STP(ReciprocalSewageTreatmentProcess)工艺由一组配有充氧装置的处理构筑物组成 ,其间设有连通管道及控制闸阀 ,能组成多种污水处理系统。污水按指定的顺序依次通过各个构筑物 ,分别进行曝气 ,固液分离和污泥回流。在处理污水时污泥也同时得到稳定 ,利用系统内共生的微生物 (活性污泥 )和高等水生生物 (鱼类 )共同完成净化任务。具有免排剩余污泥的特点 ,其净化程度优于二级处理的出水水质 (含除磷脱氮 )。
Reciprocal Sewage Treatment Process is consisted of a group of units with aeration devices and interconnected by communicating pipes and control valves. The facility is composed in diversification and the wastewater flows through each ordinal unit for aeration, solid liquid separation and sludge recycling. Simultaneously with the purification of wastewater, the sludge is stabilized, which is contributed jointly by the symbiotic microorganisms (such as activated sludge) and advanced aquatic bio communities (such as fish) growing in the water system. There is no surplus sludge discharge from the facility and the effluent of this process is better than the requirement of grade Ⅱ of the national wastewater discharge standard.
