摘要
以高温活化改性钢渣颗粒为研究对象,对其在机械搅拌条件下对水体中不同种属藻的去除效果和对藻类的光合作用活性的影响进行试验研究,并对其除藻机理进行了初步探讨。结果表明:改性钢渣颗粒对水体中各藻属均有很好的去除效果,对藻类的光合作用活性具有很好的胁迫抑制作用;改性钢渣颗粒在100r/min的搅拌强度下,对藻类的去除主要以吸附为主,在400r/min的搅拌强度下,对藻类的去除以吸附和机械损伤为主。
This paper studies the effects of granular steel slag after high temperature modification on algae removal and photosynthesis activity under conditions of mechanical stirring. The results indicate that modi- fied granular steel slag can not only effectively remove different algae in water, but also inhibit the photo- synthetic activity of algae. The removal of algae by modified granular steel slag with 100 r/min stirring in- tensity is mainly through adsorption, and removal of algae with 400 r/rain stirring intensity is mainly through adsorption and mechanical damage.
