【正文】 agent , study the coal flotation effect of using water and wastewater . The results showed that pared with the effect of water Coal, coking wastewater after use, can significantly enhanced the yield of clean coal, coal ash is enhanced tail can be used for coking coal preparation waste water production. Coal coking wastewater experiments, the best pharmaceutical system as foaming agents and collector of 1L slurry. Keywords: wastewater， coal preparation plant， floatatinon, floatation agent 內(nèi)蒙古科技大學(xué)畢業(yè)論文 III 目錄 摘 要 ......................................................................................................................................................................I ABSTRACT ..........................................................................................................................................................
