不同红树处理海水养殖尾水效果初探

为探究不同红树品种对舟山地区海水养殖尾水的处理效果。选取秋茄、桐花、白骨壤三种耐寒性较强的红树植物,对比分析三种红树人工湿地处理对虾大棚养殖尾水的净化效果,同时也将红树植物人工湿地与无植物人工湿地尾水净化效果进行了对比分析。结果表明,红树人工湿地处理海水养殖尾水效果明显好于无植物人工湿地。对比三个红树品种,总体而言,白骨壤人工湿地处理海水养殖尾水效果相对优于秋茄、桐花两个红树品种的人工湿地,而秋茄人工湿地在海水养殖尾水前期处理阶段的净化效果比较好。

Experimental s tudy on purification effects of marine aquaculture wastewater by different mangroves

In order to explore the purification effects of marine aquaculture wastewater by different mangroves in the area of Zhoushan, three mangrove plants that can resist cold better than other mangroves, which are kenaelia candel, aegiceras corniculaturn and avicennia marina, were used in the experimental study. The three mangrove plants were used to purify marine aquaculture wastewater from the greenhouses of shrimp culture for comparison and analysis. Also the unplanted constructed wetland was used as a control. The results showed that the purification effects of mangrove constructed wetlands are better than the unplanted constructed wetland. On the whole, the purification effect of avicennia marina constructed wetland is relative better than the other two. But, in the earlier stage, the kenaelia candel constructed wetland purifies the marine aquaculture wastewater better.
