Description
Изобретение относитс к области очис ки сточных вод от загр знений, преимущественно от взвешенных и коллоидных минеральных и органических веществ, например, очистки навозосодержащих сточных вод. Известны способы электролитической очистки сточных вод от взвешенных и коллоидных частиц, включающие обработк в электролизере с растворимыми желез ными электродами i , Дл увеличени глубины очистки обработку в многокамерных электролизерах .2 , Недостатком известных способов вл ет то, что из общего количества ионов железа , образующихс при анодном растворении электродов, лишь часть используетс дл образовани гидроокиси и очист ки .сточных вод, а остальной металл выноситс с обработанной жидкостью, загр зн конечный продукт. Дл вьщелени из обработанной сточной воды непрореагировавшего металла может быть использовано краГковременкое отстаивание, при котором оставшиес в воде ионы металла гидролизируютс и выпадают в осадок. Так, за 30 мин отстаивани концентраци железа в обработанной сточной воде Снижаетс с 485 до 60 мг/л или в 8-1О раз, в то врем как ХПК лишь на 30%. Пенный продукт последней камеры электролизера также состоит, главным образом, из флокул гидроокиси металла. Таким образом, пенный продукт камеры доочист ки и осадок отстойников-доочистителей содержат значительное количество железа , не прин вшего участие в процессе очистки воды, что вл етс недостатком известных технологий. Целью изобретени вл ютс повышение экономичности процесса за счет снижени энергозатрат на электролитическую обработку и сокращение расхода электродного металла. Это достигаетс тем, что пенный продукт последней ступени электролизера и осадок после отстаивани смешиваютThe invention relates to the field of sewage purification from pollution, mainly from suspended and colloidal mineral and organic substances, for example, treatment of manure-containing wastewater. There are known methods for electrolytic treatment of wastewater from suspended and colloidal particles, including treatment in an electrolytic cell with soluble iron electrodes i. To increase the cleaning depth, the processing in multi-chamber electrolyzers. 2 anodic dissolution of the electrodes, only a fraction is used to form hydroxide and purify wastewater, and the rest of the metal is carried away with the treated liquid, the contaminated end product is contaminated. In order to remove the unreacted metal from the treated wastewater, short-term sedimentation can be used, in which the metal ions remaining in the water hydrolyze and precipitate. Thus, for 30 minutes of settling, the concentration of iron in the treated wastewater decreases from 485 to 60 mg / l or 8-1O times, while the COD is only 30%. The foam product of the last chamber of the electrolyzer also consists mainly of metal hydroxide floccules. Thus, the foam product of the after-treatment chamber and the sediment of the after-purifiers contain significant amounts of iron that did not participate in the water purification process, which is a disadvantage of the known technologies. The aim of the invention is to increase the efficiency of the process by reducing the energy consumption for electrolytic processing and reducing the consumption of the electrode metal. This is achieved by mixing the foam product of the last stage of the electrolyzer and the precipitate after settling.
