在传统三室膜电解槽的基础上进行改进,将各槽室之间通过阴阳离子交换膜(均相离子交换膜)隔开,分成中间淡化室和两侧的阴阳极室,各槽室中的溶液不断循环。以期改善传统反应器无法去除有机物和脱盐率低等缺点。结果表明,电压越高脱盐率越高,但当电压升高到18 V时反应器运行电流已接近极限电流值,同时三环唑的去除率随电压升高的幅度较小。Na_2SO_4含量升高脱盐率和三环唑去除率随之升高,但当Na_2SO_4的质量浓度为10 g/L时脱盐开始出现下降。新型反应器脱盐率、电流效率更高,尤其是在高盐分的情况下,同时对有机物具有直接的降解作用,出水毒性有机物含量极低。
Based on the traditional three-compartment membrane electrolyzer, the compartments are separated by a cation-cation exchange membrane (homogeneous ion exchange membrane) and divided into an intermediate desalination chamber and cathode-anode chambers on both sides, The solution is constantly circulating. In order to improve the traditional reactor can not remove organic matter and the low rate of desalination. The results showed that the higher the voltage, the higher the desalination rate. However, when the voltage was increased to 18 V, the operating current of the reactor was close to the limit current value. At the same time, the removal rate of tricyclazole with voltage was small. The desalination rate and tricyclazole removal rate increased with the increase of Na_2SO_4 content, but desalination started to decline when the concentration of Na_2SO_4 was 10 g / L. The new reactor desalination rate, the current efficiency is higher, especially in the case of high salinity, while the direct degradation of organic matter, effluent organic matter content is extremely low.
