摘要
文章采用光伏电池为电源,采用电絮凝工艺来治理新农村微污染水体中的磷,并从电解时间、电极材料、电极板间距和起始pH等影响因素进行了研究。研究结果表明:电解时间越长,总磷的去除率越高,45 min时,达95%以上;电导率在5 min内,有一个快速升高过程,此后逐渐下降;铝板电极和铁板电极总磷的去除速率和去除效率均比不锈钢板电极高,铝极板为最佳的电极材料;最佳间距为25 mm,此时总磷的去除效率和去除速度较高;最适宜的pH范围为4～5.5该工艺可行。
In the paper,the electrocoagulation process was used to remove phosphorus from new rural micro-contamination water body.The effect of electrolysis time,electrode material,distance between electrodes,and initial pH value on total phosphorus（TP） removal was explored.The results show that TP removal efficiency becomes higher with a longer electrolysis time,and it is more than 95 % at the time of 45 min.There is a rapid increase in conductivity within 5 min,and then it decreases gradually;TP removal rate and removal efficiency used for aluminum electrodes and iron electrodes are all higher than ones for the stainless steel plate electrodes,and the aluminum plate is selected as the best electrode material.When an optimum electrode gap is 25 mm,TP removal rate and removal efficiency are all high.An optimum pH value range of 4～4.5 can be obtained.The electrocoagulation process is feasible.
