将配制好的模拟废水放置于原水箱内，开启蠕动泵向磁絮凝池泵入原水、PAC和磁粉，并以160 r/min快速搅拌5 min，之后开启磁絮凝池阀门向反应池进水，并投加PAM，以80 r/min慢速搅拌3 min后通过弹簧流量计进入超磁分离机内将磁性絮团与水分离，之后磁性絮团进入高速剪切机内被剪切成磁粉和煤粉，最后磁粉进入超磁回收机进行回收。取出水口出水测其浊度并计算去除率，筛选出最优的混凝剂、助凝剂和磁粉以及最佳的投加量，进一步改变SS初始浓度、磁鼓转速、煤粉粒径、进水流量等影响因素，确定最优的模拟高浊矿井水废水磁分离处理的水力条件，最后在最优条件下测定磁粉回收率。", "ds_quality": "
