序批式活性污泥法处理毛皮废水的研究

Study on the Treatment of Skin Wastewater by Sequencing Batch Reactor.

采用序批式活性污泥法处理毛皮模拟废水的试验条件为：水温２０℃，ＤＯ２ｍｇ／Ｌ，ＣＯＤＣｒ１５００ｍｇ／Ｌ，ＢＯＤ５９００ｍｇ／Ｌ，ＭＬＳＳ２１００ｍｇ／Ｌ，经４ｈ曝气反应后，ＣＯＤＣｒ浓度降到１００ｍｇ／Ｌ左右，ＢＯＤ５浓度降到４０ｍｇ／Ｌ左右，ＭＬＳＳ从２１００ｍｇ／Ｌ增至２６００ｍｇ／Ｌ左右．试验结果表明。

Laboratory studies indicated that experimental conditions:simulating waste water temperature 20℃,DO 2mg/L,COD Cr 1500mg/L,BOD 5 900mg/L,MLSS 2100mg/L.After 4 hours period aeration,the COD Cr dropped toward about 100mg/L,BOD 5 toward adout 40mg/L,the concentration of sludge increased from 2100mg/L to about 2600mg/L.Experimental results showed that sequencing batch reactor system to be operatted in a limit aeration schedule can not cause sludge increase rapidly.
