电浮选凝聚法处理污水最佳实验条件的探究
=============
摘要:
采用控制变量法探索电浮选凝聚法净水实验中电极大小,改变
pH 值、
电压等试验条件对实验的影响,从而找出最佳实验条件使实验现象更为明显,
能够看到浮渣及溶液分层等现象,同时尽量使实验操作简便,实验时间控制在
5—10 分钟以内以配合课堂实验教学。
Abstract: The electrical control variable method to explore
water flotation experiment coagulation electrode size,
changing the pH, voltage and other effects of the
experimental test conditions, in order to identify the best
experimental conditions for the experimental phenomena
become more evident, to see the floating residue and the
solution layered phenomena, while as far as possible
experiments is simple, time control experiments in the 5-
10 minutes to tie in with classroom teaching experiment.
