  • 摘要: 近年来，河流污染严重，严重影响了社会的发展，治理河水污染成为目前急需解决的问题。研究了石墨-铁板电极电解法对城市内河中重污染水体中磷去除的可行性；分析了静置时间、电解时长、初始磷浓度、电压、pH及极板间距对电解法除磷效果的影响，确定了电解法处理重污染水体的最佳运行参数，比较了电解法处理实际河水和模拟河水的TP去除效果。结果表明，重污染河流水体中的磷在较短时间内可以得到去除，在静置时间为3 h，电压为10 V，极板间距为1.5 cm，pH保持在中性或弱酸性，电解时长在10~15 min时，TP去除率达到90%以上。同时，在最佳运行条件下，电解法处理实际河水效果较好。
    Abstract: The pollution of rivers is serious in recent years, which affects the development of society seriously. The river pollution governance has become the most urgent problem to be solved. We studied the feasibility of graphite and iron plate electrodes-electrolysis method to remove phosphor in heavily polluted urban rivers. We discussed the effects of the standing time, electrolytic time, initial phosphate concentration, applied voltage, pH and electrode spacing on phosphorus removal; thus determined the optimal operating parameters of electrolysis for heavily polluted water; and compared the TP removal efficiency of the actual water with simulated river water by electrolysis method. The results showed that the phosphorus in the heavily polluted river could be removed by electrolysis in short time. When the applied voltage was 10 V, the plate spacing 1.5 cm, pH in neutral or weak acid, and the electrolytic time at 10~15 min, the TP removal rate could reach above 90%. At the same time, the electrolysis method acted on the actual river water well under the optimum operating conditions.
