改性焦渣复合吸附剂处理印染废水研究

实验研究了改性焦渣复合吸附剂热处理印染废水时各种因素的影响,结果表明:用十二烷基苯磺酸钠溶液改性焦渣并与活性炭质量比按10∶1制成复合吸附剂,处理印染废水,在吸附剂用量为废水量0.4%,pH值控制在6,废水水温20℃,吸附时间20m in的实验条件下,脱色率达90.8%,COD去除率达84.8%,SS去除率达到90.2%,处理效果良好。 Experimental study of a modified coke slag composite adsorbent heat treatment dyeing wastewater the influence of various factors,the results showed that: SDBS modified solution with activated carbon and coke residue than quality made by 10 ∶1 composite adsorbent,dyeing wastewater treatment,in the amount of wastewater capacity adsorbent 0.4%,PH value in the six control,waste water temperature at 20℃,20min adsorption time of the experimental conditions,decolorization rate of 90.8%,84.8% removal of COD,SS removal rate reached 90.2%,handling well
