利用络氨铜控制景观水体藻华

研究了络氨铜对不同生长期的典型蓝藻（铜绿微囊藻,Microcystis aeruginosa）15d生长抑制影响的基础上,开展了络氨铜对不同时期景观池水中叶绿素a含量的影响,并跟踪测定了其中的有效铜离子浓度变化.结果表明,络氨铜在0.10mg·L-1（络氨铜的有效浓度,下同）时,可完全抑制适应期铜绿微囊藻的生长;在4d...

Controlling algal blooms in the landscape water with copper sulfate-ammonia complex

The effect of copper sulfate-ammonia complex on Microcystis aeruginosa (the dominant algae of Cyanobacteria algal bloom) was determined by a 15-day prolonged growth inhibition test in a landscape water sample. Elimination of chlorophyll-a was also studied. The results indicated that copper sulfate-ammonia complex at 0.10 mg·L^-1 could completely inhibit the growth of Microcystis aeruginosa at the lag phrase and significantly decrease the concentration of chlorophyll-a in the landscape water sample in 4 days. Copper sulfate-ammonia complex showed a greater algaecidal effect for Microcystis aeruginosa at lag phrase than at log phrase, and a greater elimination effect for chlorophyll-a in the landscape water sample collected in April than in March and May. Therefore, better algaecidal effects can be achieved when the copper sulfate-ammonia complex was applied in early phrase of algal bloom.
