【摘要】 利用三氯化铁絮凝剂和沉水植物苦草在治理富营养化水体中的优缺点,复合应用于改善富营养化水体水质。结果表明,三氯化铁可有效降低水体的悬浮物浓度和总磷浓度,为水生植物早期的生长提供良好的条件;水生植物可保持和加强三氯化铁絮凝剂对水质的处理效果,并降低水体的总氮浓度。更多还原

【Abstract】 Based on the advantages and disadvantages of FeC13 coagulant and the submerged macrophyte Vallisneria spiralis in the treatment of eutrophic waters, both of them were used for the improvement of water quality.The results showed that FeC13 could reduce the concentration of SS and TP efficiently,which provided better condition for the growth of aquatic plants of the first growth stage,and the aquatic plants were able to maintain and enhance the water improvement effects by FeCl3 as well as to reduce the TN concentration.更多还原
