矿井水净化处理混凝剂投加控制技术

混凝剂投加控制是矿井水净处理工艺过程中的关键环节,其结果直接影响到矿井水处理效果。当采用转子流量计或计量泵混凝剂控制技术时,在处理水量和水质变化时,混凝剂的投加量不能及时改变,从而影响矿井水净化处理效果;采用单因子流动电流混凝剂投加控制技术时,由于矿井水中含有一定量的乳化液和机油,使单因子流动电流传感器产生较大的误差,因此阻碍了该技术在矿井水净化处理中的应用;而混凝剂自动投加控制技术ADSMD在数学模型的基础上,由模拟试验取得工艺技术参数,再通过在线传感器、变送器、PLC、上位机和计量泵实现控制,从而确保了出水水质,并可降低运行成本,提高了矿井水处理技术的自动化水平。

Adding Control Technology of Coagulant for Mine Water Purification Treatment

The coagulant adding control is the key link in the mine water purification treatment technique processing. The results of the coagulant adding control would be directly to influence the mine water treatment results. When the coagulant adding control with the rotor flowmeter or measuring pump,once the water quantity and water quality varied during the waste water treatment,the adding quantity of the coagulant would not be on timely changed and thus the mine water purification treatment results would be infl...
