Fenton试剂处理港口化学品洗舱废水

根据珠海某港口化学品洗舱废水的组成,配置甲醛、甲苯、苯酚的单独污染物模拟废水,采用Fenton试剂对港口废水和模拟废水进行氧化处理。通过实验探讨了不同的H2O2和Fe2+浓度、pH值、反应时间下各种废水COD的去除情况,确定了各种废水最佳的操作条件。港口废水在最佳的操作条件下COD去除率约为88%,废水的COD质量浓度从2 000~2 200 mg/L降到低于280 mg/L,废水由原来的无法生化变为易生物降解。苯酚、甲醛、甲苯模拟废水在各自最佳的操作条件下,COD去除率也都达到85%以上。

Treatment of port cabin washing wastewater containing chemicals by Fenton reagent

Cabin washing wastewater containing chemicals in a port in Zhuhai, along with three artificial wastewater solutions containing only formaldehyde, toluene and phenol, were treated with Fenton reagent. The effects of concentrations of H2O2 and Fe^2＋ , different pH values and oxidation time on the COD removal rate were studied. The optimal treatment conditions for different wastewaters were presented. The results show that the removal rate of COD in the port wastewater was 88 % in the optimal condition, under which COD decreased from 2000 - 2200mg/L to less than 280 mg/L, and the port wastewater became easy biodegradable. The removal rate of COD from the artificial wastewater solution of formaldehyde, toluene and phenol was more than 85% in the optimal condition.
