化学化工实验废水排放的监测分析与治理实践

以广西大学化学化工实验大楼排放的实验废水为例,对其水质进行为期半年的监测.监测结果表明:该水的有机物含量不高但排水量大;有代表性的重金属污染中,Hg的平均含量约为0.015 m g/L、C r平均含量低于0.1 m g/L,两者均低于《城市污水综合排放标准》(GB 8978-1996).根据监测结果,提出采用厌氧生物滤池对实验废水进行初步处理,处理后的废水可直接排入市政管道,不会对环境造成不良的影响.

Chemistry laboratory wastewater monitoring and controlling practise

Taking chemistry laboratory wastewater of GXU as example,this paper have been monitored the quality of the effluent for about half a year.The result shows that the wastewater is of low organic matters but the flow is large;and in the heavy metal pollution monitoring,the average amount of mercury is about 0.015 mg/L and the Cr is below 0.1 mg/L.Both of them are lower than the city wastewater comprehensive discharge standard(GB8978-1996).According to the monitoring results,this paper have given a controlling method which named anerobic bio filter.The effluent after ABF can discharge into the civil pipes directly and can not give the environment any bad effect.
