电絮凝处理黄土塬地区村镇集蓄雨水的实验研究

Rainwater Collection in Rural Area of Loess Plateau by Electro-coagulation

采用电凝聚对黄土塬地区村镇集蓄雨水进行处理。通过改变极板间距、极板电压、电解时间,进行了对集雨水中COD,浊度,NH3-N,UV254的去除率研究。结果表明:电解时间15 min,极板间距为10 mm,极板电压为15 V的条件下,电絮凝对集蓄雨水中浊度、氨氮、UV254、COD有较好的去除效果,去除率分别为95%、63%、48%、80%,高于化学絮凝的处理效果。

Based on experiment for treatment of the rainwater collection in rural area of loess plateau by electro-coagulation , influence of parameters such as the density of electric current, the electrified time and inter-electrode distance on electrocoagulation process were studied by analyzing the removal efficiency of turbidity, NH3-N, UV254 and COD. Results indicated that when the voltage,the electrified time and inter-electrode distance were 15V , 15rain and 10mm respectively, the removal efficiency of turbidity , NH3-N, UV254 and COD were about 95 %. 63 %. 48 and 80% and better than the chemical coagulation.
