污水处理厂总磷去除实验

Experiment on removal of total phosphorus in sewage treatment plant

污水处理厂为节能增效,决定将除磷药剂用聚合硫酸铁代替聚合氯化铝,通过对不同厂家聚合氯化铝、不同聚合硫酸铁、不同加药量对废水总磷做去除实验,通过大量比对实验得出最佳药剂,考虑到聚丙烯酰胺的絮凝效果[1],采用聚合硫酸铁与聚丙烯酰胺相结合的工艺方法,提高了总磷的去除效率,使出水总磷稳定的降至0.5mg/L达标排放。

The sewage treatment plant for energy efficiency, decided to medicament of phosphorus removal by polymeric ferric sulfate instead of polyaluminium chloride, polyaluminium chloride by different manufacturers and different polymerization iron sulfate, different dosage of wastewater phosphorus removal experiments done by a large number of experiments, the optimal agent, taking into account the flocculation effect of polyacrylamide[1]. The process of iron sulfate and polyacrylamide combination, improve the removal efficiency of total phosphorus, the effluent TP stable to 0.5mg/L emission standard.
