Abstract:

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.
