中文摘要：一體化反應(yīng)池主要特點：
1）工藝流程短，構(gòu)筑物和設(shè)備少，不設(shè)初沉池，調(diào)節(jié)池和單獨的二沉池，污泥自動回流，投資省，能耗低，占地少，管理簡便。
2）處理效果穩(wěn)定可靠，其BOD5和SS去除率均在90％-95％或更高。COD得去除率也在85％以上，并且硝化和脫氮作用明顯。
3）產(chǎn)生得剩余污泥量少，污泥不需小孩，性質(zhì)穩(wěn)定，易脫水，不會帶來二次污染。
4）造價低，建造快，設(shè)備事故率低，運行管理費用少。
5）固液分離效率比一般二沉池高，池容小，能使整個系統(tǒng)再較大得流量和濃度范圍內(nèi)穩(wěn)定運行。
6）污泥回流及時，減少污泥膨脹的可能。


English summary:The integral whole turns the main characteristics in pond in reaction:
1)The craft process is short, the builds the thing is little with the equipments, do not establish the beginning sink the pond, regulating the pond with lone of two sink the pond, automatic reflux in dirty mire, investment province, can consume low, cover little, manage simple.
2)Handle the result stability is dependable, its BOD5 does away with the rate with the SS all in 90%-95% or higher.The COD have to  away with the rate too above 85%, and the nitric turns with take off the nitrogen function obviously.
3)Creation the dirty amount of mire in surplus is little, the dirty mire do not need the child, the kind is stable, easy dehydration, can't bring to pollute two time
4)Build the price low, construct quick, the equipments trouble rate is low, circulating the administrative expense little.
5)The liquid separates efficiency ratio general two sink the pond high, the pond permits small, can make whole system been bigger again get the discharge stabilize the movement with density scope inside.
6)Dirty mire reflux on time, the possibility that reduce the dirty mire the inflation.
