摘要
某缺水城市的景观河道水体富营养化现象严重,为此采用新型除磷药剂——锁磷剂对该河道水体进行除磷试验,考察了锁磷剂的除磷效果。结果表明,锁磷剂对富营养化河道水体的除磷效果显著,当投药量为100 mg/L、试验时间为21 d时,总磷、溶解性总磷和磷酸盐浓度分别由初始的0.66、0.45和0.64 mg/L降至0.06、0.06和0.01 mg/L左右,完全达到了《地表水环境质量标准》(GB 3838—2002)的V类标准。另外,当投药量分别为100、150和200 mg/L时,锁磷剂的除磷效果差别不明显,综合考虑处理效果和成本,初步确定锁磷剂的适宜投量为100 mg/L。
A landscape river in a water-shortage city of north China has serious eutrophication. Therefore, a new chemical called phoslock was used to perform phosphorus removal experiment from the river water, and the phosphorus removal effect of phoslock was inverstigated. The results show that ph-oslock is effective in phosphorous removal from eutrophic river water. When the dosage of phoslock is 100 mg/L and the experiment time is 21 days, the concentrations of TP, DTP and phosphate are decreased from 0.66 rag/L, 0.45 mg/L and 0.64 mg/L to 0.06 mg/L, 0.06 mg/L and 0.01 mg/L. They can all meet V criteria specified in the Environmental Quality Standards for Suuface Water （GB 3838 -2002 ）. There is no significant difference in phosphorous removal effect when the dosages are 100 mg/L, 150 mg/L and 200 mg/L respectively. Considering the treatment effect and cost, the suitable dosage is determined as 100 mg/L.
