摘要
化工企业废水处理最好的方法是活性炭处理方法,活性炭具有很强的净化能力。能够对废水中的其他物质进行净化,以达到去除废水中杂质的作用,分别采用粉末形状活性炭、颗粒形状活性炭、纤维活性炭对化工企业排污废水进行净化处理,通过对废水中的COD、氨氮浓度、废水浊度、pH值净化进行对比分析。纤维活性炭净化速率最快,净化所需时间最短,对化工企业排污废水中COD净化容量最高、浊度去除率最高,但对氨氮浓度和pH值没有明显的净化效果。
The best method for wastewater treatment in chemical enterprises is activated carbon treatment. Activated carbon has a strong purification capacity. It can purify other substances in the wastewater to remove the impurities in the wastewater. The powdered activated carbon, granular activated carbon and fibrous activated carbon are used to purify the sewage from the chemical industry, and the COD and ammonia nitrogen concentration in the wastewater are Comparative analysis of wastewater turbidity and pH purification. The experimental results show that the fiber activated carbon has the fastest purification rate and the shortest purification time. The COD purification capacity and the turbidity removal rate are the highest in the sewage discharge of chemical enterprises, but there is no obvious purification effect on ammonia nitrogen concentration and pH value.
