Abstract
Изобретение относитс к способам очистки сточных вод от ионов т желых металлов, органических примесей и может быть использовано дл очистки стоков текстильных, химических предпри тий и гальванических производств. Целью изобретени вл етс повышение степени очистки и скорости осаждени частиц взвеси. Дл осуществлени способа воду последовательно обрабатывают сначала основной золой - с содержанием CAO 30-50% до PH 8,75-9,25, а затем - кислой золой с содержанием CAO 3-5% до PH 6,5 и отдел ют осадок отстаиванием. Используют золу с размером частиц 30-70 мкм. Способ позвол ет обеспечить 100%-ную очистку воды от ионов т желых металлов, поверхностно-активных веществ, нефтепродуктов и увеличить скорость осаждени частиц взвеси до 0,95 мм/с. 1 з.п. ф-лы, 3 табл.The invention relates to methods for treating waste water from heavy metal ions, organic impurities, and can be used for cleaning waste textiles, chemical plants and electroplating industries. The aim of the invention is to increase the degree of purification and the rate of sedimentation of suspended particles. In order to carry out the process, water is sequentially treated first with basic ash — with a CAO content of 30–50% to a PH of 8.75–9.25, and then acidic ash with a CAO content of 3–5% to a PH of 6.5, and the precipitate is separated by settling. Ash is used with a particle size of 30-70 microns. The method allows 100% purification of water from heavy metal ions, surfactants, and petroleum products and increases the sedimentation rate of suspended particles to 0.95 mm / s. 1 hp f-ly, 3 tab.
Description
Изобретение относитс к способам очистки сточных вод от ионов т желых металлов и органических примесей и может быть использовано дл очистки стоков текстильных, химических предпри тий и гальванических производств.The invention relates to methods for treating waste water from heavy metal ions and organic impurities and can be used for cleaning waste textiles, chemical plants and electroplating industries.
Цель изобретени - повышение степени очистки и скорости осаждени .The purpose of the invention is to increase the degree of purification and deposition rate.
Способ осуществл ют следующим образом .The method is carried out as follows.
Сточную воду с рН 7,1, содержащую, мг/л хром 22,4; цинк 28,5; медь 11,7; никель 21,5; ПАВ 74,8; нефтепродукты 12,9 обрабатывают в реакторе объемом 60 л сначала основной золой с содержанием СаО 30-50% (торф на зола) до рН 8,75-9,25 при посто нном перемешивании в течение 10-30 мин, а затем - кислой золой с содержаниемSewage water with a pH of 7.1, containing, mg / l, chromium 22.4; zinc 28.5; copper 11.7; nickel 21.5; Surfactant 74.8; Oil products 12.9 are treated in a 60 l reactor first with basic ash with a CaO content of 30–50% (peat for ash) to a pH of 8.75–9.25 with constant stirring for 10–30 min, and then acidic ash with content
СаО 3-5% (Кузнецкие угли) до рН 6,5 при посто нном перемешивании в течение 3--5 мин. Суспензию подвергают осветлению в напорных гидроциклогах при давлении 0,2-0,3 МПа, Степень очистки воды от ионов т челых металлов , ПАВ и нефтепродуктов составл ет 100%. Скорость осаждени взвеси 0,95 мм/с.CaO 3-5% (Kuznetsk coal) to pH 6.5 with constant stirring for 3--5 min. The suspension is subjected to clarification in pressure hydrocyclics at a pressure of 0.2-0.3 MPa. The degree of water purification from ions of heavy metals, surfactants and oil products is 100%. The sedimentation rate of the suspension is 0.95 mm / s.
Параллельно осуществл ют очистку воды по известному способу. Результа ты очистки представлены в табл.1.In parallel, water treatment is carried out by a known method. The cleaning results are presented in table 1.
В табл.2 представлены результаты очистки воды по предложенному способу при использовании дл обработки воды золы с разными размерами частиц. Отделение взвеси из воды осуществл ют путем отстаивани в стекл нных ци линдрах.Table 2 presents the results of water purification according to the proposed method using ashes with different particle sizes for treating water. The suspension is separated from water by settling in glass cylinders.
Данные по очистке воды при обработке кислой золой до разных значений рН представлены в табл.3.Data on water purification when processing acidic ash to different pH values are presented in table.3.
