Изобретение относитс к сельскому хоз йству , оно может быть использовано дл очистки и обеззараживани жидкого навоза.The invention relates to agriculture, it can be used for cleaning and disinfecting liquid manure.
Известен способ очистки сточных вод электрофлотацией с иримененнем флотационных реагентов, например хлорной извести. Однако примен емые флотационные реагеиты ие всегда вызывают коагул цию высокодисперных иримесей, а обеззараживаиие недостаточно.A known method of wastewater treatment by electroflotation with flotation reagents and, for example, bleach. However, the used flotation reagents do not always cause the coagulation of highly dispersive irimeses, and disinfection is not enough.
Цель изобретени - иолучеиие из фильтрата навозной жижи осветленной воды, пригодной дл новторного использовани . Поставленна цель достигаетс введением в очищаемую жидкость коагул тора, например фосфорной кислоты и/или ее соли, с последующей электрофлотацией водородом скоагулированнЕ х иримесей и дезипфекцией осветленного фильтрата атомарным кислородом, выдел ющимс при электрофлотации.The purpose of the invention is the imitation of the clarified water slurry filtrate suitable for repeated use. This goal is achieved by introducing a coagulant, such as phosphoric acid and / or its salt, into the liquid to be purified, followed by electroflotation of coagulated yrimeses with hydrogen and disipfection of clarified filtrate with atomic oxygen evolved during electroflotation.
Способ осуществл ют следующим образом. The method is carried out as follows.
Навозна жижа (фильтрат), содержаща высокодисиерсные и коллоидные иримеси, иосле отделени крупных механических частей смещиваетс с коагул нтом, который вл етс иитательны.м веществом дл растений и животных . Скоагулированные иримеси флотируютс пузырьками водорода в электрофлотаторе .A slurry (filtrate) containing highly dispersed and colloidal irrimesis is recovered, and after the separation of large mechanical parts, it is displaced with coagulum, which is an effective substance for plants and animals. The coagulated irrimessies are floated with hydrogen bubbles in an electroflotter.
С целью обеззараживани и минерализацииFor the purpose of disinfection and mineralization
органических примесей очищенна жидкость иоступает дл дополнительной обработки атомарным кислородом, получаемые на аноде при электролизе в электрофлотаторе.The organic impurities are purified liquid and supplied for additional treatment with atomic oxygen, obtained at the anode during electrolysis in an electrofloater.
Оч1 щенна и продезинфицированна атомарным кислородом вода исиользуетс дл технических нужд и новторного смыва навоза в замкнутой рециркул ционной системе.The water, stripped and disinfected with atomic oxygen, is used for technical needs and for repeated washing of manure in a closed recirculation system.
Применение коагул тора, нанример фосфорной кислоты и/или ее соли, новышает содержание иитательных веществ в выдел емой твердой фракции, ускор ет процесс очистки, улучщает ее качество, снижает затраты на очистку. Коагул тор адсорбируетс твердой фазой. Вносимое количество коагул тора зависит от концеитрации примеси в очищаемой навозной жиже и ие иревыщает 0,2% от массы очищаемой жидкости.The use of a coagulant, phosphoric acid and / or its salt nanoparticles, increases the content of nutrients in the emitted solid fraction, accelerates the cleaning process, improves its quality, reduces the cost of cleaning. The coagulum is adsorbed by the solid phase. The amount of coagulant to be injected depends on the impurity co-impurity in the slurry to be cleaned, and does not even squeeze 0.2% of the mass of the liquid being cleaned.
Предлагаемый способ очистки навозной жижи дает возможность замкнуть цикл исиользовани значительной частн воды на крупных животиоводческих комилексах, снизить потребность хоз йств в пресной воде, предотвратить засорение окружающей среды, особенно грунтовых вод, снизить затраты на утилизацию навоза получить обогащенное питательными веществами концентрированное удобрение, которое также может быть использовано как добавка к комбикормам. 3 Предмет изобретени Способ очистки фильтрата иавозной жижи электрофлотацией, включающий введение химического реагента и обработку смеси водородом и атомарным кислородом, отличающийс тем, что, с целью получени из фильтрата навозной жижи осветлениой воды. пригодной дл повторного использовани , в 4 фильтрат добавл ют химический реагент, об .гадаюи1,ий иитательиыми свойствами дл расттеиин и животиых, на пример фосфорную кислоту и/или ее соли, провод т флотацию водородом скоагулированных при-месей и затем дезинфекцию осветленного фильтрата атомарным кислородом, выдел ющимс при электрофлотации . The proposed slurry purification method makes it possible to close the cycle of using significant private water in large livestock breeding farms, reduce the need for fresh water in the households, prevent the environment from clogging, especially groundwater, reduce the cost of manure utilization to obtain nutrient-rich concentrated fertilizer, which can also to be used as an additive to compound feeds. 3 The subject of the invention is a method for purifying the filtrate by spraying electroflotation, including the introduction of a chemical reagent and the treatment of the mixture with hydrogen and atomic oxygen, characterized in that, in order to obtain a slurry from the filtrate, water is clarified. suitable for reuse, chemical reagent, vol. 1, synthetic properties for rasteiine and animals, such as phosphoric acid and / or its salts, are added to 4 filtrate, for example, phosphoric acid and / or its salts are floated with hydrogen-coagulated admixtures and then disinfected with clarified filtrate with atomic oxygen released during electroflotation.
