摘要
在对国内外除藻剂进行大量分析和筛选的基础上 ,提出 3种较为有效的杀藻剂 ,并进行了单、复配除藻对比试验 .结果表明 :DDAB有效浓度及最佳杀生浓度最低 ,CTAB次之 ,H2 O2 最差 ;DDAB及CTAB的最佳单用浓度分别为 1× 1 0 - 6 mg/ml、(5～ 1 0 )× 1 0 - 6 mg/ml;复配以 0 .2× 1 0 - 6 mg/ml+1 .4× 1 0 - 6 mg/mlCTAB复配除藻效果最好 ;
With a large mount of analysis and comparison about foreign and domestic algaecide, three effective kinds for algaecide comparing experiment have been selected. The results are as follows:the effective concentration and best concentration of the DDAB are both the lowest for alga-killing, CTAB's is middle, and H 2O 2's is the highest. The best concentrations of the DDAB and CTAB for single usage are respectively 1×10 -6 mg/ml and (5～10)×10 -6 mg/ml. And for mixture is 0.2×10 -6 mg/ml (DDAB)+1.4×10 -6 mg/ml(CTAB).All the algaecides have similar effect to both filamentous algae and floating algae.
