为研究电流密度对电化学阻垢性能的影响,设计了电化学阻垢实验装置,研究了不同电流密度(100~400?A·m-2)处理条件下,溶液的溶解性总固体(TDS)和电导率(EC)的变化规律。结果表明:增加电流密度可以提高电化学阻垢性能,在电流密度为200?A·m-2的条件下,阻垢率约为不通电条件下的6~8倍。在电化学水处理过程中,溶液TDS和EC随电流密度的增加而线性减小,其中电场增强、极板积垢和pH降低是TDS减小的主要原因,Ca2+浓度降低以及电极钝化是EC减小的主要原因。在电流密度为400?A·m-2的条件下,TDS和EC极小值分别为804?mg/L和1 482?μs·cm-1,TDS和EC降低率分别为47.0%和48.0%。
- Abstract:
-
To investigate the effect of current density on electrochemical scale inhibition performance, an electrochemical scale inhibition device was designed. The changes of total dissolved solids(TDS)and electrical conductance(EC) in different current densities(100-400?A·m-2) were studied. It was shown that increasing current density can improve electrochemical scale inhibition performance. When the current density is 200?A·m-2, the scale inhibition rate is about 6-8 times that of the non-energized condition. The TDS and EC decrease linearly with the increase of current density during electrochemical water treatment. Additionally, the decrease of TDS might be attributed to the enhancement of electric field, the reduction of electrode plate fouling and pH values. While, the decrease of EC might be attributed to the reduction of Ca2+ concentration and electrode passivation. At a current density of 400 A·m-2, the minimums of TDS and EC are 804 mg/L and 1 482 μs·cm-1, which decrease by 47.0% and 48.0%, respectively.
