改性粘土对球形棕囊藻的消除研究
|
摘要
球形棕囊藻(Phaeocystisglobosa)暴发藻华时多以囊体形态出现,但迄今缺乏囊体消除方法研究。本文在球形棕囊藻藻华暴发水域取样进行实验,比较了原土及不同改性材料制备的改性粘土对囊型球形棕囊藻的消除效果,并考察了水体pH、溶解有机碳(DOC)、溶解无机磷(DIP)等在治理前后的变化。结果表明:粘土经表面改性后对球形棕囊藻消除能力明显提高,对囊体亦有一定破碎作用,且改性粘土浓度越高,其除藻破囊效果越好;在有效消除囊体细胞情况下,添加改性粘土对水体中pH及DOC含量影响较小,但可以导致DIP水平降低。
At present,removal of Phaeocystis globosa that presented in forms of colonies during harmful algal blooms remains to be explored.We compared the removal efficiencies of P.globosa with original clay and different modified clays(MC):MCⅠ,MCⅡ,and MCⅢ(see detail formulations in the text),and determined the changes of pH,dissolved organic carbon(DOC),and dissolved inorganic phosphorus(DIP).The results show that MC addition increased the removal efficiencies to P.globosa.The algal biomass removal efficiencies of original clay,MCⅠ,MCⅡ,and MCⅢ in dosage of 0.2 g/L were 46.01%,52.87%,80.06%,and 99.57%,respectively.The experiment showed that P.globosa colonies were decolored and disrupted after MC addition.However,the MC addition showed no significant effect on the pH and DOC in the algae culture but reduced the DIP levels.
