Изобретение относитс к способам очистки сточных вод текстильных пред при тии, в частности, содержащих проционовые, пр мые и дисперсные красители, и может быть использовано дл очистки сточных вод, содержащих органиче.ские вещества, Г1АВ и красители .The invention relates to methods for treating wastewater from textile pre-agents, in particular, containing procyon, direct and disperse dyes, and can be used for purifying wastewater containing organic substances, G1AB and dyes.
Известен способ очистки стачных вод при промывке и крашении шерсти, включающий введение коагул нта и последукнцее отстаивание с отделением образовавшихс хлопьев LjA known method of purification of wastewater during washing and dyeing wool, including the introduction of coagulant and subsequent sedimentation with the separation of the formed Lj flakes
Однако данный способ недостаточно )фективен по отношению к проционовым . Пр мым и дисперсным красител м .However, this method is not sufficiently effective with respect to protions. Direct and dispersed dye m.
Наиболее близким к изобретению по технической сущности и характеристике обрабатываемых вод вл етс способ очистки сточных вод текстильных предпри тий, включающий введение коагул нта в виде соли железа 2 j .Closest to the invention in terms of the technical nature and characteristics of the water being treated is a method of treating wastewater of textile enterprises, including the introduction of coagulant in the form of an iron salt 2 j.
Недостатком зтого способа вл етс то, что он не позвол ет достиг нуть степени очистки, требуемой при сбросе отработанных сточных вод текстильных предпри тий или повторном их использовании.The disadvantage of this method is that it does not allow to achieve the degree of purification required when discharging waste water of textile enterprises or reusing it.
Цепь изобретени - повьвиение степени очистки.The circuit of the invention is the increasing degree of purification.
Поставленна цель достигаетс тем, что в сточные воды текстиль10 ных предпри тий ввод т соль железа одновременно или последовательно с солью алюмини , олова и свинца. Кроме того, последовательно ввод т коагул нты, содержащие железо, алю15 миний,олово и свинец в пересчете на ионы металла в количестве 10-50; 5-35; 5-25 и 4-15 мг/л соответственно и выдерживают 2-8 мин.This goal is achieved by the fact that iron salt is introduced into wastewater of textile enterprises simultaneously or sequentially with aluminum, tin and lead salts. In addition, coagulants containing iron, aluminum, tin, and lead, in terms of metal ions in an amount of 10-50; 5-35; 5-25 and 4-15 mg / l, respectively, and incubated for 2-8 minutes.
Сущность способа заключаетс в The essence of the method is
