Изобретение относитс к способам очистки сточных вод предпри тий цветной и черной металлургии и может, быт использовано на горно-обогатительных и металлургических комбинатах, имеющих сточные воды, содержащие мьшь к, силикат-ионы и взвешенные вещества, стабилизированные щелочью и жидким стеклом.The invention relates to methods for treating wastewater from enterprises of nonferrous and ferrous metallurgy and can be used in mining and concentration plants and metallurgical plants having wastewater containing matter, silicate ions and suspended substances stabilized by alkali and liquid glass.
Цель изобретени - повышение степени очистки от взвещенных веществ при обеспечении одновременной очистки от силикат-ионов и мьшш ка.The purpose of the invention is to increase the degree of purification from particulate matter while ensuring simultaneous purification from silicate ions and mice.
Способ осуществл ют путем обработки сточных вод коагул нтом, в качестве которого используют отход титано-магниевого производства - отработанный расплав хлораторов процесса хлорировани титанового сьфь . Коагул нт ввод т в количестве, обеспечивающем соотношение ионов железа в отходе к SiOj общей в воде 1:(4,5- 6,6), Затем воды обрабатьшают известью до рН 9,5-10,0 и подвергают отстаиванию .The method is carried out by treating wastewater with coagulant, which is used as a waste of titanium-magnesium production - spent melt chlorinators of the process of chlorination of titanium coal. The coagulant is introduced in an amount that provides the ratio of iron ions in the waste to SiOj total in water 1: (4.5-6.6). Then the water is treated with lime to a pH of 9.5-10.0 and subjected to settling.
Отход представл ет собой порошок темно-зеленого цвета. Основными компонентами отхода вл ютс , %: хлорид алюмини 2,5-4,3; железа 14,2-17,8 магни 10,2-13,2; кали 19,1-31,3; натри 7,0-31,0; хрома 4,0-5,0; оксиды титана 3,0-3,4 и кремни 6,4-8,2.The waste is a dark green powder. The main components of the waste are,%: aluminum chloride 2.5-4.3; iron 14.2-17.8 magni 10.2-13.2; potassium 19.1-31.3; sodium 7.0-31.0; chromium 4.0-5.0; titanium oxides 3.0-3.4 and silicon 6.4-8.2.

К 250 МП сточных вод (слив сгустител молибденового концентрата ) добавл ют 1 г отхода, перемешивают в течение 3 мин, ввод т известь до рН 10. После отстаивани в течение 1 сут,взвешенные вещества отсутствуют , содержание SiOjj общей составл ет 127,2, мьш1ь ка 0,05 мг/л.Example 2. Purify wastewater containing, mg / l: suspended solids 3800; SiO total 1216; 1 250 g of waste water (discharge of a molybdenum concentrate thickener) is added 1 g of waste, stirred for 3 minutes, lime is added to pH 10. After settling for 1 day, no suspended substances are present, the total SiOj content is em 127.2, lb 0.05 mg / l.
В таблице представлены данные по вли нию дозы реагента и величины рН на эффективность очистки сточных вод.The table presents data on the effect of the reagent dose and the pH value on the wastewater treatment efficiency.
Использование в качестве коагул нта отхода титано-магниевото производства позвол ет полностью очистить сточные воды от взвешенных веществ. При этом степень очистки от двуокиси кремни возрастает в 4,6 раза, от мышь ка - в 6 раз.The use of titanium-magnesium production in the quality of coagulum makes it possible to completely purify wastewater from suspended substances. In this case, the degree of purification from silicon dioxide increases by 4.6 times, from the mouse - by 6 times.
