【摘要】：电絮凝作为一种具有广泛应用前景的低廉高效污水处理技术,已经被证明在工业废水、生活污水等污染严重的水体处理上具有显著效果,但是目前对于电絮凝净化微污染水的相关研究较少。通过对电絮凝分批处理河水的实验研究,分析电絮凝方法处理微污染水的可行性,讨论极板间距的改变对电絮凝处理效果的影响。结果表明,电絮凝处理技术可以用于微污染水净化中,在电流密度为17.75 A/m2、极板间距为1.5 cm的条件下,反应30 min时,色度去除率为73.76%,浊度去除率为76.00%,悬浮固体去除率为85.71%,化学需氧量去除率为42.86%,总磷去除率为61.36%。在电絮凝反应中,极板间距对于微污染水的色度、浊度、悬浮固体和总磷去除效果具有明显的影响。
[Abstract]:As a kind of low cost and high efficiency sewage treatment technology with wide application prospect, electroflocculation has been proved to have remarkable effect in industrial wastewater, domestic sewage and other seriously polluted water treatment. However, there are few researches on the treatment of micro-polluted water by electroflocculation. The feasibility of treating micro-polluted water by electroflocculation is analyzed through the experimental research on the treatment of river water by electroflocculation in batches. The effect of electrode spacing on the effect of electrocoagulation treatment was discussed. The results showed that the electroflocculation technology could be used in the purification of micro-polluted water under the condition of current density of 17.75 A / m ~ (2) and polar plate spacing of 1.5 cm, and the reaction time was 30 min. The chromaticity removal rate is 73.76, the turbidity removal rate is 76.00, the suspended solid removal rate is 85.71, the chemical oxygen demand removal rate is 42.86, the total phosphorus removal rate is 61.360.In the electroflocculation reaction, the distance between polar plates is turbidity for micro-polluted water, The removal effect of suspended solid and total phosphorus is obvious.
