Abstract
Изобретение касаетс обработки воды электрохимическими методами и позвол ет снизить энергозатраты при хлорировании слабоминерализованных вод за счет увеличени выхода по току активного хлора. В известном способе хлорировани воды, включающем ее электролиз и периодическую депассивацию катода, используют магнетито-титановые аноды, установленные с возможностью взаимного перемещени , причем электролиз ведут при межэлектродном рассто нии 1,4-2,8 мм и плотности тока 10-200 А/м 2, а депассивацию осуществл ют периодическим повышением плотности тока до 240-300 А/м 2 при межэлектродном рассто нии 0,8-1,2 мм. Хлорирование провод т при удельном количестве пропущенного электричества 0,02-0,04 А .ч/л и концентрации активного хлора 1-5 мг/л. 1 табл.The invention relates to the treatment of water by electrochemical methods and makes it possible to reduce the energy consumption during the chlorination of low-mineralized water by increasing the current output of active chlorine. In the known method of water chlorination, including its electrolysis and periodic depassivation of the cathode, magnetite-titanium anodes are used that are installed with the possibility of mutual displacement, and the electrolysis is carried out at an interelectrode distance of 1.4-2.8 mm and a current density of 10-200 A / m 2, and depassivation is carried out by periodically increasing the current density to 240-300 A / m 2 with an interelectrode distance of 0.8-1.2 mm. Chlorination is carried out at a specific amount of the missed electricity of 0.02-0.04 A. / L and an active chlorine concentration of 1-5 mg / l. 1 tab.
