【摘要】 试验选用三种不同的生活污水,对其浊度和CODCr进行测定及相关分析。分析结果表明:当污水浊度低时,CODCr也低;当污水浊度高时,CODCr也高,这三种污水各自的浊度和CODCr都存在较好的相关性。这样便可用易于测定的浊度来间接反映污水的CODCr和BOD5,从而判断污水的污染程度和处理效果。更多还原

【Abstract】 Three kinds of domestic sewage treated by different methods have been tested.Their turbidities and CODCr have been analysed,trying to find out if there is any inner relationship.The results show that when their turbidities are low,their relevant CODCr are low,as well;and when their turbidities are high,their CODCr are high,as well.In addition,the individual turbidity and relevant CODCr has pretty good relativity.Therefore,the turbidity that can be determined easily can be used for reflecting indirectly the concentration of CODCr and BOD5 in the sewage.Then,the pollution degree and the treatment efficiency can be evaluated accordingly.更多还原
