中文摘要:

以模拟集雨窖水为实验原水,通过改变电絮凝过程中的电流密度、通电时间、极板间距等因素值的大小,研究电絮凝在原水浊度去除中的的最优参数组合。得出影响浊度去除效果的各因素主次关系依次是:电流密度>极板间距>反应时间,当电流密度为18.89A/m²,极板间距为1 cm,反应时间为13 min时为电絮凝去除浊度的最优组合,浊度去除率为92.94%,同时对窖水中的CODMn、UV₂₅₄也有一定的去除效果。

英文摘要:

The collecting rain water was used as raw water in this experiment. The current density, electrified time, polar board spacing were changed in electro-coagulation process to search the optimum parameter for removal of raw water turbidity. The sequence relation of each factor one by one which affect the removal effect is current density>polar board spacing>contact time. When the current density was 18.89 A/m², polar board space was 1 cm, contact time was 13 mins ,which is the optimum combination in electro-coagulation process of turbidity removal. Removal rate of CODMn and UV₂₅₄ was improved in rainwater collection while the removal rate of turbidity was 92.94%.
