Description
дельными потоками одновременно лодают сточную воду, предварительно на,гр1етую до температуры 40-80° С и электролит (технически чиста жидкость с 1неболйМим,и Добавками NaCI ;цл.и НС1), охла жденный до температуры 5- 15°С; гори это.м сточную воду подают неиосредственио над электродами , а элвкт.родит - через .нижнее,основа нйё элёктродизе1ра восход щим потоком, который, проход межэле.ктрод1ное простра ство , насыщаетс продуктами раствореВИЯ электродов (пидроожисью металла).At the same time, waste water is supplied at the same time, preliminarily heated to a temperature of 40-80 ° C and an electrolyte (technically pure liquid with 1 NebolicMim, and NaCI Additives; tc. and HC1) cooled to a temperature of 5-15 ° C; In this case, waste water is supplied indirectly over the electrodes, and the electrolyte rotates through the lower one, the base of the electrolyzer electrical outlet, in an upward flow, which, passing the interelectrode space, is saturated with solution products of the electrodes (metal hydration).

The degree of heating and cooling of water and electrolyte is determined by the initial content of impurities in the wastewater; by increasing the content of impurities, the temperature gradient of liquids is also increased.
Ниже приведены результаты испытаний предложенного и известного способов электрохимической очистки.Below are the results of tests proposed and known methods of electrochemical cleaning.
