10、、表4-35。在浓浓水直，排放条件下，水量比为淡水:浓水:极水=1：1.2：0.2（或1：0.6：0.2）。这时水的利用率约45.5%55.5%。采用浓水循环可降低水耗量。 b电渗析器设备技术in southwest of Zhejiang Provincial Committee of the partys struggle, develop democratic United Front against Japan, established the armed forces and the anti-Japanese base area, decided to establish the

21、成。极区的主要作用是给电渗析器供直流电，将原水导人膜堆的配水孔，将淡水和浓水排出电渗析器，并通人和排出极水。电极托板的作用是加固极板和安装进出水接管，常用厚的硬聚氯乙烯板制成。电极的作用是接通内外电路，在电渗析器内造成均匀的直流电场。阳极常用石墨，铅、铁丝涂钉等材料;阴极可用不锈秀钢等材料制成。极框用来在极板和膜堆之间保持一定的距离，构成极室，也是极水的通道。极框常用厚57mm的粗网多水道式塑料板制成。垫板起防止漏水和调整厚度不均的作用，常用橡胶或软聚氯乙烯板制成。电渗析器通电后，电极表面发生电才电极反应，致使阳极水呈酸性，并产生初生态的氧02和氰气Cl2。阴极水呈碱性，当极水中有Ca2+和M
22、g2+时，有可能生成CaC03和Mg (OH)2水垢，结集在阴极上，阴极室有O2和H2排出。因此极水要畅通，可不断排出电极反应产物，有利于电渗析器正常运行。b电渗析器设备技术in southwest of Zhejiang Provincial Committee of the partys struggle, develop democratic United Front against Japan, established the armed forces and the anti-Japanese base area, decided to establish the CPC Zheji
