Description
Изобретение относитс к стабилгиза- ционной обработке щелочных сточных вод и может быть использовано в химических , коксохимических, нефтехкми- ческих и сланцеперерабатывающих производствах .The invention relates to the stabilization treatment of alkaline wastewater and can be used in chemical, coke-chemical, petrochemical and shale-processing industries.
Целью изобретени вл етс повьше- ние степени стабилизации.The aim of the invention is to increase the degree of stabilization.
В качестве реагента дл стабилизационной обработки используют кислый гудрон - отход серно-кислотной очистки в производстве ароматических углеводородов .Основными компонентами кислого гудрона вл ютс , мас.%: серна кислота 50-65, органические вещества 17-.29, в т.ч. сульфокислоты 13-20.Acidic tar is used as a reagent for stabilization treatment — a waste of sulfuric acid purification in the production of aromatic hydrocarbons. The main components of acidic tar are, wt%: sulfuric acid 50-65, organic matter 17-29., Incl. sulfonic acids 13-20.
Стабилизационной обработке подвер- гают поступающие на золоотвалы промышленные и ливневые сточные воды, характеризующиес высоким содержанием гидроксида кальци и значением рН 12,3-12,5.Industrial and storm sewage entering the ash dumps, characterized by a high content of calcium hydroxide and a pH value of 12.3-12.5, is subjected to stabilization treatment.
Способ осуществл ют путем обработки воды кислым гудроном до рН 7,2. Доза реагента составл ет 2,3 - 2,5 кг/м воды.The method is carried out by treating water with acidic tar to a pH of 7.2. The dose of the reagent is 2.3-2.5 kg / m of water.
Пример. Стабилизационной обработке подвергают сточные воды золо- отвалов ПО Сланцехим г.Кохтла - Яр- ве эсер с рН 12,5, общей жесткостью 46,0 мг-экв/л и содержанием иона кальци 46,0 мг-экв/л. Дл стабилизации используют кислый гудрон, содержащий , мас.%: серна кислота 63,8;Example. The wastewater of ash dumps at the Kohtla-Yarveve Slantsekhim town of pH 12.5, with a total hardness of 46.0 meq / l and a calcium ion content of 46.0 meq / l is subjected to stabilization treatment. For stabilization, acidic tar containing, in wt.%, Is used: sulfuric acid 63.8;

органические вещества 25,0, в т.ч. сульфокислоты 14,4.Organic matter 25.0, incl. sulfonic acids 14.4.
Реагент ввод т до рН 6,8. Содержание иона кальци в стабилизированной воде составл ет, мг-экв/л: через 24 ч 44,9; через 48 ч 44,7; через 120 ч 44,7.The reagent is injected to a pH of 6.8. The content of calcium ion in stabilized water is mEq / L: after 24 hours, 44.9; after 48 hours, 44.7; after 120 h 44.7.
В таблице представлены результаты по стабилизационной обработке воды кислым гудроном по предлагаемому способу и серной кислотой по способу- прототипу при содержании Са в исходной воде 46 мг-экв/л и снижении рН при обработке реагентом с 12,5 до 6,8. Степень стабилизации оценивают отношением содержани кальци в обработанной воде к содержанию его в исходной пробе.The table presents the results of the stabilization treatment of water with acidic tar on the proposed method and sulfuric acid according to the method-prototype with a Ca content in the source water of 46 mEq / l and lowering the pH during processing with the reagent from 12.5 to 6.8. The degree of stabilization is evaluated by the ratio of the calcium content in the treated water to its content in the initial sample.
