Experimental Research on micro-polluted water pretreatment by utilizing electrocoagulation method

Now some drinking water sources are polluted slightly. The conventional water treatment processes can no longer fulfill the requirement for micro-polluted water treatment, which poses not only a threat to human health but a challenge to traditional treatment process. This thesis has a research on micro-polluted water pretreatment effect by utilizing electrocoagulation method. The result demonstrates that, under the optimal condition by utilizing this method, COD, ammoinacal nitrogen and total phosphorus in slightly polluted water can be removed effectively: the removal rate of COD is 60%-70%, the removal rate of total phosphorus is 70%-80%, the ammoinacal nitrogen is 60%-70%.
