摘要
考察了不同微电解方式对含高浓度阴离子表面活性剂(AS)废水的预处理效果,结果表明,在铁炭填料分别为F3(铁屑,规格3 mm×10 mm)、C3(活性炭,规格D 2 mm×3 mm),进水pH为3.5,停留时间为30 min的相同条件下,当m(F3)∶m(C3)=2∶1时,二元微电解法对废水AS及COD的平均去除率分别为51.32%、48.9%;当m(F3)∶m(Cu)∶m(C3)=60∶60∶40时,三元微电解法对废水AS及COD的平均去除率分别为54.14%、49.0%。从处理效果和实际工程应用综合考虑,选用二元微电解法预处理该废水。
The pretreatment effect of the wastewater containing highly concentrated anionic surfactant （AS） by different micro-electrolysis modes has been investigated. The results show that under the same conditions：the mass ratio of F3 （iron,size 3 mmxlO ram） and C3 （activated carbon,size D 2 minx3 ram） is 2：1, pH 3.5 and retention time 30 rain,the average removing rates of AS and COD are 51.32% and 48.9% ,respectively by binary micro- electrolysis. When the mass ratio of F3,Cu and C3 is 60：60：40,the average removing rates of AS and COD are 54.14% and 49.0%, respectively by ternary micro-electrolysis. Out of consideration for the treatment effectiveness and actual application, the binary micro-electrolysis should be selected for the pretreatment of such wastewater.
