摘要:
The present invention relates to treatment of industrial wastewater, and more particularly wastewater from a fertilizer plant such as a nitrophosphate, organic or organo-mineral fertilizer plant. Chloride ions and other impurities can be removed by electrolysis and to control the pH of the cathode chamber, treated wastewater from the anode chamber is directed to the cathode chamber and new wastewater sent to the anode chamber for the subsequent run of electrolysis. This is an efficient method of controlling the pH of the cathode chamber and preventing white scaling from appearing on the cathode. By efficiently reducing the chloride concentration in the fertilizer wastewater, it is then possible to safely recirculate the wastewater back to the fertilizer plant.
摘要(中):
本发明涉及工业废水的处理,更具体地涉及来自肥料厂如硝酸磷肥,有机或有机矿物肥料厂的废水。 氯离子和其他杂质可以通过电解除去并且控制阴极室的pH值,来自阳极室的处理过的废水被导向阴极室并且新的废水送到阳极室用于随后的电解过程。 这是一种控制阴极室pH并防止白色污垢出现在阴极上的有效方法。 通过有效地降低肥料废水中的氯化物浓度,可以安全地将废水循环回到肥料厂。 p>
