摘要
为了研究废水中有机物的去除问题,针对某企业含有机物废水进行了对比试验,采用了Fenton-絮凝联合工艺去除废水中的COD(化学需氧量)和浊度,考察了初始pH值、H2O2投加量、H2O2与Fe2+投加物质的量比、反应时间、絮凝剂投加量以及絮凝剂投加时的pH值对COD以及浊度去除效果的影响。结果表明,采用最佳工艺参数组合后,浊度去除率和COD的去除率分别为99.32%和97.27%。
In order to study the removal of organic matter in wastewater,a comparative experiment was carried out for organic wastewater in an enterprise.The combined Fenton-flocculation process was used to remove COD and turbidity in wastewater,and the influences of the initial pH value,H2O2 dosing quantity,H2O2 and Fe2+dosing molar mass ratio,reaction time,flocculant dosing quantity and pH value of flocculant addition on COD and turbidity removal effect were investigated.The results showed that the turbidity removal rate and COD removal rate were 99.32%and 97.27%,respectively,after using the optimum combination of technological parameters.
