印染废水具有有机物含量高,难降解物质浓度高,色度大、悬浮物多,水质、水量变化大,含有微量毒性物质等特点。目前,通用的处理方法是生化处理,但是存在色度及CODCr难去除以及产生二次污染等问题。本实验以粉末活性炭为催化剂,建立了微波协同氧化工艺,对模拟印染进行处理。微波协同氧化活性炭吸附和单纯微波辐射3种不同工艺的对比实验表明,微波诱导氧化工艺具有明显的优越性。本实验考察了甲基橙浓度、微波功率、辐射时间、活性炭用量对甲基橙去除率的影响。结果表明,在甲基橙质量浓度为30 mg/L,活性炭用量为1.0 g/L,微波功率为432 W,辐射时间为9 min时,处理效果最好。

Dyeing wastewater with high organic compounds,high concentrations of refractory material,color large,suspended solids and more,water quality,water changes,containing traces of toxic substances and so on.At present,the general approach is biological treatment,but there is one color and CODCr difficult to remove,and the generation of secondary pollution.In the study,powdered activated carbon as the catalyst,the establishment of co-oxidation process for microwave,simulated dyeing wastewater.Oxidation of activated carbon with microwave and microwave radiation and the simple process of comparing 3 different experiments show that microwave induced oxidation process has obvious advantages.this experiment investigated the methyl orange concentration,microwave power,irradiation time,activated carbon dosage on the removal rate of methyl orange.The results showed that the concentration of methyl orange 30 mg /L,carbon dosage of 1.2 g/L,the microwave power 432 W,irradiation time was 10 min,the best effect.
