硫酸盐及其组合除藻的比较分析

Kraft and Combinations Algae Removal of a Comparative Analysis

研究了CuSO4.5H2O、Al2(SO4)3、KAl(SO4)2.12H2O单一除藻和与硅藻土、石英砂、泥沙组合除藻的规律,以及对COD、NH3—N、P、浊度4项指标的影响规律。试验结果表明,这3类硫酸盐对除藻都有很好的效果。在相同的初始条件下(即相同的水质条件、投药量、温度和搅拌强度),Al2(SO4)3的除藻效果优于CuSO4.5H2O和KAl(SO4)2.12H2O,对浊度也有较高的去除率,而对COD、NH3—N、P等指标则无较大改善。

Researched on the CuSO4·5H2O,Al2（SO4）3,KAl（SO4）2·12 H2O separate dosage,and diatomite,quartz sand, silt and algaecide for mixed law and the efficiency of COD,NH3 - N, P, turbidity four indicators of the impact. The results showed that these three kraft on the algaecide had very good results.In the same initial conditions （the same water quality conditions for the same amount of drugs,the same temperature and stirring the same intensity）, the Al2 （SO4）3 algae removal was efficiency better than CuSO4·SH2O and KAl（SO4 ）2· 12H2O, and there was a very strong on the turbidity removal efficiency, but for COD, NH3 - N, P, and other indicators, there was no significant improvement.
