Description
Изобретение касаетс получени eo/iqic нистых фильтрующих материалов, которы(е можно использовать при очистке щелочн1 х растворов травильн ых производств от меди.The invention relates to the production of eo / iqic filter media, which (e can be used in the cleaning of alkaline solutions of pickling plants from copper.
Цель изобретени - повышение степени очистки сточных вод и увеличение срока зксплуатации фильтров. :The purpose of the invention is to increase the degree of wastewater treatment and increase the service life of filters. :
При мер 1. Верховой торф низкой степени разложени (до 20%) в количестве 3 кг измельчают и обрабатывают .0,09; моль/л раствором гидроксида ндтри (t2 15л) при 85°С в течение 1 ч при перемешивании . .; , . ; , : Example 1. Low-grade peat moss (up to 20%) in an amount of 3 kg is ground and processed .0.09; mol / l solution of hydroxide ndtri (t2 15l) at 85 ° C for 1 h with stirring. ; , ; ,:
После окончани обработки торф отфильтровывают на сите с диаметром отверстий 1-2 мм. Промывают дистиллированной водой до достижени рН промывных вод, равного 8,&-9,0 и сушат на воздухе при 80After the treatment is completed, the peat is filtered on a sieve with a hole diameter of 1-2 mm. It is washed with distilled water until the pH of the wash water is 8 & -9.0 and dried in air at 80

П р и м е р 6. Провод т очистку сточных вод медно-травильного производства. С Этой целью воды с содержанием меди 200205 г/л нейтрализуют 30% растворами гиДроксида натри или кали при сооТнощении сточных вод : тидроксид металла 2:1 рН 11-12, затем фильтруют эти воды через фильтр, заполненный фильтрующим материалом , полученным по примерам Т-5, а также с использованием необработанного торфа. Данные приведены в таблице.PRI me R 6. Conduct wastewater treatment of copper-pickling production. With this goal, water with a copper content of 200205 g / l is neutralized with 30% sodium or potassium hydroxide solutions at wastewater concentration: metal hydroxide 2: 1 pH 11-12, then this water is filtered through a filter filled with filtering material obtained according to examples T- 5, as well as using raw peat. The data are given in the table.
Технико-экономическими преимуществами предлагаемого способа вл ютс увеличение степени очистки от меди в 5-7 раз, а также времени работ.ы фильтра в 600 раз.The technical and economic advantages of the proposed method are an increase in the degree of purification from copper by 5-7 times, as well as the filter operation time by 600 times.
