摘要
比较了锁磷剂、聚合硫酸铁(PFS)和聚合氯化铝(PAC)的除磷性能。在原水的磷酸盐浓度为1 mg/L(以P计)的条件下,若将磷酸盐浓度降到0.4 mg/L以下,三者的最佳投量分别为150、1和20 mg/L;14 d的监测结果表明,PFS的除磷长效性较差,而锁磷剂和PAC具有较佳的除磷长效性,在富营养化水体除磷应用上更具优势。
The phosphorus removal performance of phoslock, polymeric ferric sulfate (PFS) and polyaluminium chloride (PAC) was compared. When the concentration of phosphate in raw water is 1 mg/L (calculated in P) , the optimum dosages of three chemicals are 150 mg/L, 1 mg/L and 20 mg/L respectively to reduce phosphate to below 0.4 mg/L. The monitoring results within 14 days show that except PFS, phoslock and PAC have better long-time effect for phosphorus removal from eutrophic water.
