Изобретение относитс к электрохимической очистке загр зненных жидкостей и может быть применено дл очистки природных и сточных вод, содержащих минеральные и органические примеси.The invention relates to the electrochemical purification of contaminated liquids and can be applied to the purification of natural and waste waters containing mineral and organic impurities.
Цель изобретени - снижение расхода электроэнергии на проведение процесса.The purpose of the invention is to reduce energy consumption for the process.
Пример. В процессе электро- коагул ционной обработки загр зненных жидкостей, например природных и сточных вод, происходит образование анодной окисНой пленки и катодных отложений, преп тствук цих растворению металла на аноде и вызывающих увеличение энергозатрат. Дл борьбы с указанными влени ми периодически измен ют пол рность тока, подаваемого на электроды. Однако после осуществлени переполюсовки- за счет наличи остаточной пол ризации электродов скачкообразно увеличиваетс сила тока на врем их депол ризации . Осуществление депол ризации электродов без затрат электроэнергии на данный процесс можно осуществить путем взаимного гашени тока пол ризации при замыкании междуExample. In the process of electrocoagulation treatment of contaminated liquids, for example, natural and waste waters, anodic oxide film and cathodic deposits are formed, preventing the metal from dissolving at the anode and causing an increase in energy consumption. To combat these effects, the polarity of the current supplied to the electrodes is periodically changed. However, after reversal, due to the presence of the residual polarization of the electrodes, the current is abruptly increased during the time of their depolarization. The implementation of the depolarization of the electrodes without the cost of electricity for this process can be accomplished by the mutual quenching of the polarization current when a short
