碳氮磷比对菌胶团的影响与活性污泥膨胀的关系

EFFECTS OF C,N,P RATIO ON ZOOGLOEA AND SLUDGE BULKING

在活性污泥法的曝气池中，由微生物形成的菌胶团与废水成分的碳、氮、磷比例有着密切关系。如果比例失调会导致菌胶团变性、解体，从而影响活性污泥的生物学特性与理化性质、发生“污泥膨胀”影响废水处理效果。运用我国著名数学家华罗庚的《优选法》──０，６１８”法，拟定维尼纶有机配水氮的实验区带为０．８─１０，在４个条件相同的反应器中作试验，结果证明：Ｃ＝Ｎ：Ｐ＝１００：３．９６：０．９３的范围，菌胶团活性高，结构良好，水处理效果最佳，运转稳定。

Zoogloes spp are connected with C,N,P ratio in aeration tank of activated sludge process,If the ratio is dislocation,zoogloea will decompose, eveneffect on biology feature and physical chemistry quality of activated sludge andresult in bulking, which effects on waste water treatment,By using the 0.618 me-tkod invented by famos mathematician Hua Luogeng,vinylon waste water N regwas set from 0.8 to lo. Testing in four reactOrs, which were in the same conditi-on,The result determined that C: N: P =100: 3.96 : 0.93 and zoogloea spp have highactivity, good construction.Also,the result of water treatment was good al1d thereactor operated steady.
