【摘要】 研究北京转河磷的形态分布及混凝对各形态磷的去除效果。试验表明,颗粒态总磷约占水体总磷的67.57%,可溶性总磷占32.43%。从季节分布看,总磷质量浓度在当年的7~9月份达到最高,接近270μg/L,在12月,次年1月达到最低,接近120μg/L。在混凝沉淀后各形态磷大部分得以去除,颗粒态磷去除率达88.8%,缩合态磷去除率相对最低,为61.72%,正磷酸盐几乎完全被去除。更多还原

【Abstract】 The distribution of various forms of phosphorus in the Zhuanhe River of Beijing was investigated.Particulate total phosphorus and dissolved total phosphorus were 67.57% and 32.43%,respectively,of the total phosphorus.Total phosphorus concentration was the highest,approaching 270 μg/L,in July,August and September,and was down to the lowest,about 120 μg/L,in December and January.The removal efficiency of phosphorus by coagulation and flocculation was studied.Experimental results show that most of the phosphorus was removed.The removal rates of particulate phosphorus and polyphosphate were,respectively,88.8% and 61.72%,and the orthophosphate was almost totally removed.更多还原
