摘要
电絮凝法具有处理效率高、操作简便、能够同时去除悬浮物和胶体物质、不需要额外添加化学药剂等,被广泛应用于废水处理、污水处理、饮用水净化等领域.本文应用电絮凝法,进行洗煤废水连续流试验,分析不同水力停留时间、不同电流强度、不同极板数量对废水悬浮物去除效果的影响.结果显示:最佳水力停留时间、最佳电流强度、最佳的极板数量分别为15 min、15 A、24块;基于进水浓度的增加,电解槽中电阻增加,电解电压在进水浓度增加的情况下不断增加,显示出良好的悬浮物去除率.
Abstract
The electrocoagulation method has high treatment efficiency,easy operation,the ability to simultaneously remove suspended solids and colloidal substances,and does not require additional chemical agents.It is widely used in fields such as wastewater treatment,sewage treatment,and drinking water purification.This article applies the electrocoagulation method to conduct continuous flow experiments on coal washing wastewater,analyzing the effects of different hydraulic retention times,current intensities,and electrode numbers on the removal efficiency of suspended solids in wastewater.The results showed that the optimal hydraulic retention time,optimal current intensity,and optimal number of plates were 15 min,15 A,and 24 pieces,respectively;Based on the increase of influent concentration,the resistance in the electrolytic cell increases,and the electroly-sis voltage continuously increases with the increase of influent concentration,showing a good suspended solids removal rate.
