对4种金属离子Al3+、Ca2+、Fe3+、Fe2+单因子和双因子联合作用对养殖水体中磷的去除效果进行研究。结果表明,单因子作用中以Al3+和Ca2+除磷效果较好,除磷率可达50%以上。双因子联合作用中,Al3+-Fe2+、Ca2+-Fe3+、Ca2+-Fe2+除磷效果较为显著,可达60%～76%。
The combined effect of four kinds of metal ions Al3 +, Ca2 +, Fe3 +, Fe2 + single factor and two factors on phosphorus removal in aquaculture water was studied. The results showed that the removal of phosphorus by Al3 + and Ca2 + was better and the removal rate of phosphorus was more than 50%. Two-factor combination, Al3 + -Fe2 +, Ca2 + -Fe3 +, Ca2 + -Fe2 + phosphorus removal effect is more significant, up to 60% to 76%.
