摘要
采用芬顿技术对经过ASBR&SBR生化处理的化妆品废水进行生化后处理,进一步降低出水中有机污染物的浓度.通过芬顿各因素试验探究,优化工艺参数,获得ASBR&SBR-芬顿联合技术的最佳工艺:CODCr/H2O2=3/2、Fe2+/H2O2=1/2、反应起始pH 3.0、反应时间t=5 min.CODCr去除率可达70%,出水CODCr值达50 mg/L以下,达到一级排放标准.
Cosmetic wastewater is a relatively highly concentrated organic wastewater , which contains different kinds of surfactants .The technology of ASBR ＆ SBR , a kind of wastewater biochemical treatment , can effectively reduce most of contaminants in wastewater .After biochemical treatment , cosmetic wastewater still contains refracto-ry organics, which makes the discharge water still having a COD Cr of 130 -170 mg/L.Therefore, the cosmetic wastewater only treated by ASBR ＆ SBR cannot meet the discharge standard .The Fenton technology was used to treat the discharge water of ASBR ＆ SBR .Based on test and analysis , the CODCr can be reduced to less than 50 mg/L, and the removal rate can reach 70%under the optimized process parameters which were：CODCr/H2 O2 =3/2, Fe2＋/H2 O2 =1/2,pH=3.0,t=5 min.
