摘要
研究了磁场作用下壳聚糖与Fe3O4复配去除淡水藻华.结果表明,在壳聚糖用量1.6mg/L,Fe3O4用量4mg/L的情况下,通过0.5T的外磁场富集可使藻个数由4.80×106个/mL降为2.80×103个/mL;叶绿素a去除率达100%.藻液浊度、COD、总N、总P含量的去除率分别为99.6%、85.0%、73.9%、28.7%,并初步探讨了磁聚除藻的机理.
Removal of algal blooms in freshwater by chitosan and Fe3O4 compound under magnet field action was studied. Under the condition of the amounts of chitosan and Fe3O4 were 1.6, 4mg/L, 0.5T magnetic field could effectively remove the algal number from 4.80×10^6cells/mL to 2.80×10^3cells/mL; and chlorophyll-a removal rate reached 100%. The removal rate of alga liquor turbidity, COD, total N and total P were 99.6%, 85.0%, 73.9% and 28.7% respectively, and the mechanism of magnetic polymerism removal of alga was explored preliminarily.
