| 摘 要： | 本文研究了2种无机改性粘土在3种不同改性配比下对浒苔微观繁殖体去除效果及萌发的影响。结果发现，去除率随改性粘土及改性剂用量的增加而升高，相同条件下硫酸铝(AS)改性粘土对浒苔微观繁殖体的去除效果优于聚合氯化铝(PAC)改性粘土，其中1:5 PAC改性粘土在0.5 g/L时去除率为62%，AS改性粘土则可达到80%。添加改性粘土后上层水体中浒苔微观繁殖体相对萌发率随改性粘土及改性剂用量的升高而降低，总体系相对萌发率表现为先升后降趋势，在改性剂浓度为0.1 g/L时相对萌发率达到最高。两种改性体系中微观繁殖体在1:3配比、1.0 g/L浓度下均未能萌发。该结果显示，改性粘土可以有效去除浒苔微观繁殖体并抑制其萌发，这为我国绿潮灾害的防控提供了一种新思路。

| Abstract: | Two kinds of inorganic modified clay with three modifier/clay ratios were compared on the effect of removal and germination of Ulva prolifera microscopic propagules. The results indicated that removal efficiency increased with the rising amount of modified clay and modifier. AS modified clay was more effective than PAC modified clay, under the same concentration and modifier/clay ratio. The removal efficiency of 1:5 PAC modified clay under 0.5 g/L was 62 percent while AS modified clay was up to 80 percent. According to the data calculated after removal experiment, relative germination rate of microscopic propagules in upper water column decreased with the increasing of modified clay and modifier. In total water column, the relative germination rate rose firstly then fell with the peak at 0.1 g/L of modifier. Microscopic propagules treated with 1:3 modified clay failed to germinate under the concentration of 1.0 g/L in both AS and PAC modified clay. In general, suitable concentration of modified clay can remove the Ulva prolifera microscopic propagules effectively and inhibit their germination successfully, which provides a new possible way for the prevention and control of green tide disasters. |
