| 摘 要： | 以工业废渣钡渣为水处理剂,研究钡渣对水中磷去除率的影响,进水含磷10 mg/L,钡渣投加量5 g,处理时间90 min,pH为11时,去除率达81.9%.实验表明,钡渣与氢氧化钙协同作用去除水中磷时,去除率高于钡渣或氢氧化钙单独作用的处理效果.投加比例为(钡渣1 g+氢氧化钙1.5 g)/1 mg磷,水中磷的去除率达到90.42%,出水含磷量已经降低到1 mg/L以下,达到国家排放标准.去除率随着pH提高而增加.

| Abstract: | With barium residue as water treatment agent,the phosphorus removal from wastewater by barium residue and lime was studied.Results showed that barium residue and lime synergistic effect on the removal is higher than them independent effect.Under the dosage of barium residue 1 g + Ca(OH)2 1.5 g/mg,the removal can reach 90.42%,the effluent is less than 1mg/L,national emission standard can be met. |
