摘要
采用Fenton氧化法深度处理经过生化处理后的造纸法再造烟叶废水,研究了H2O2用量、Fe2+用量、反应时间以及初始pH因素对CODCr去除率的影响,确定了最佳试验条件.结果表明,n(H2O2)∶n(Fe2+)为6∶1,H2O2用量36.75 mmol/L,Fe2+用量6.125 mmol/L,搅拌反应时间30 min,初始pH为3时,CODCr去除率达最大值为72.26%,再添加PAM进行絮凝沉降处理,最终出水水质CODCr为60 mg/L.
Fenton oxidation was used to remove CODcr ot paper- process reconstltuteo tot）acco wastewater treated by biochemical processes. The effects of factors including c （ H202 ）, c （ Fe2 ＋ ）, reaction time and initial pH on CODc, removal efficiency were investigated, and the optimal conditions were determined. The results showed that the CODcr removal of wastewater reached 72.26% , when n （ H202 ） ： n （ Fe2 ＋ ） = 6： 1, c （ H202 ） = 36.75 mmol/L,c（H20） = 6. 125 mmoL/L,t = 30 min and initial pH =3. Then PAM was added for flocculation process and the CODcr of the final effluent was 60 mg/L.
