| 摘 要： | 针对某选煤厂煤泥水难以自然沉降的问题,从煤泥水本身的矿物组成出发,探讨了絮凝的机理,通过理论分析和实验研究,选用了3种凝聚剂和3种絮凝剂对煤泥水进行絮凝沉降实验,研究出最佳的凝聚剂和絮凝剂以及最佳药剂配比,加速了煤泥水的沉降,实现了洗水闭路循环。

| Abstract: | The wastewater from coal dressing contains large amounts of fine particles which are difficult to naturally settle.From slurry's mineral composition in coal dressing wastewater,this paper analyzes the mechanism of promoting the settlement of particle by coagulation.Through the experiments of coagulating and flocculating treatment for coal dressing wastewater,the suitable addition amounts and ratios of coagulant and flocculant were determined.The experimental results demonstrated that the coagulation treatme... |
