摘要
通过对各种混凝剂的应用情况及优缺点进行分析,选取目前常用的几种混凝剂对铁路隧道施工废水处理进行试验,分析比对施工废水的处理效果。试验结果表明,"聚合铝-有机高分子复合混凝剂"不仅对废水中悬浮物质去除效果好,而且对SS等指标去除效率相对较高,同时对铁路隧道施工废水p H偏高的状况有一定的改善作用,有利于降低废水处理费用。
Through the analysis of the application, advantages and disadvantages of various coagulant, several coagulant commonly used at present are selected to test the treatment of railway tunnel construction wastewater, and the treatment effect of construction wastewater is analyzed and compared. The test results show that the ＂polymerized aluminum-organic polymer composite coagulant＂ not only has a good effect on the removal of suspended matter in wastewater, but also has a relatively high removal efficiency for SS and other indicators, and has certain conditions for the high pH of railway tunnel construction wastewater. The improvement effect is beneficial to reduce the cost of wastewater treatment.
