将自制复合絮凝剂聚硅硫酸铁(PFSSi)用于市政污水除磷,考察了影响PFSSi除磷效果的一些因素,确定了PFSSi复合絮凝剂除磷的优化配比和用量。在优化条件下,对模拟污水中磷的去除率为96.7%,浊度去除率为92%;对实际污水中磷的去除率为82.3%,浊度去除率为96.5%。结果表明该复合絮凝剂有良好的除磷、除浊性能。
In this paper, the application of home-made composite flocculant PFSSi in phosphorus removal from municipal wastewater as studied. Through studying some conditions which affect the phosphorus removal effects of PFSSi ,the optimal conditions of PFSSi had been achieved. Under the optimum conditions,96.7% phosphorus and 92% turbidity were removed for simulation wastewater. 82. 3% phosphorus and 96.5% turbidity were removed for actual wastewater. The results revealed that the phosphorus and turbidity removal effects of this composite flocculant were very agreeable.
