摘要
随着目前水体藻类富营养化日益严重,国内外针对藻类的去除技术可分为物理、化学、生物法。实验采用国外引进的"去藻247"作为除藻剂,通过对滇池藻类去除效果进行试验和分析,研究"去藻247"中生物Cu2+通过改变水体中氮磷比例以及氮磷浓度的变化,以达到除藻的目的。结果表明,降低TP的浓度更易加大藻类的去除率,并且,其去除率随着藻类厚度(3￣15mm)的增加而提高,说明了"去藻247"具有一定的生物稳定性。
With algae eutrophication in the water growing gravely, home and abroad against the algae removal technology can be divided into physical, chemical and biological methods. ＂Algaegon 247＂ which was introduced from fremdness was used in this experiment. The removal effect of algaes in pianchi was tested and analysed to research the biologic Cu^2＋ of ＂Algaegon 247＂ which reduced algaes by changing proportion and concentration of TN and TP. The results showed that the concentration reduction of TP is easier to increase algae removal rate. Its increasing removal rate of algae with the thickness （3 - 15 mm） additions showed that the ＂Algaegon 247＂ had some biological stability.
