摘要
以铝、掺硼金刚石为阳极,不锈钢为阴极构建三电极系统处理含藻水,考察了电流密度、通电时间、沉降时间、初始pH、极板间距对处理效果的影响。结果表明,各因素对藻的去除率的影响顺序为:电流密度>通电时间>沉降时间>初始pH>极板间距,而且电流密度2 m A·cm^(-2),通电时间为30 min,沉降时间为15 min,pH=6,极板间距取1.0 cm为实验的最优工况点。
Anti-algal water treatment was conducted in a three-electrode system using aluminum and borondoped diamond as the anode and stainless steel as the cathode. The effects of the operating parameters,such as current density,electrolysis time,initial pH,setting time,and electrode gap were studied. The results revealed that the ordering of these factors in terms of the strength of their effect on the algae removal efficiency is as follows: current density 〉electrolysis time 〉setting time 〉initial pH 〉electrode gap. The optimal operating conditions were identified as a current density of 2 m A·cm^-2,electrolysis time of 30 min,setting time of 15 min,initial pH of 6,and electrode gap of 10 mm.
