摘要
根据废水CODCr机理,研究CODCr自动监测试剂用量,在满足监测的前提下,有效降低废液中Hg2+、Cr6+离子的含量;针对CODCr自动监测废液重金属含量高,易造成二次污染,开展对废液处理利用的研究,提取银制成回收试剂重复使用,对Cr6+、Hg2+等有害离子进行无害化处理,降低废液对环境的危害。
According the mechanism of COD Cr wastewater to research the automatic monitoring of reagent COD Cr , under the premise satisfy monitoring , the content of ions of Hg 2＋, Cr6＋in the waste was effectively reduced.Automatic monitoring of CODCr waste for high heavy metal content was easy to cause secondary pollution , the use of waste water treatment was researched , extracts made recyclables from recycled silver reagents was reused , and Cr6 ＋, Hg2＋ions was got harmless process treatment and disposal to reducing waste harmful for the environment.
