Description
Изобретение относитс к сорбционным способам очистки сточных вод и может быть использовано дл очистки сточных вод красильного производства. Такие сточные воды содержат красители пр мые, кислотные, дисперсные, катионные, урзолы, дубильные закрепители, а также мыльно-содовый раствор , содержащий синтетические моющие вещества - ОП-7 и ОП-10.The invention relates to sorption methods for wastewater treatment and can be used for the treatment of wastewater from a dyeing industry. Such wastewater contains direct, acidic, dispersed, cationic, urzol dyes, tanning fixatives, as well as a soap-soda solution containing synthetic detergents - OP-7 and OP-10.
Целью изобретени вл етс повышение степени очистки сточных вод красильного производства.The aim of the invention is to increase the degree of purification of wastewater dye production.
Дл осуществлени способа обработку сточных вод ведут адсорбентом - отраоо- тайным активированным углем после процесса очистки водорода в производстве капролактама от органических соединений.In order to implement the process, wastewater is treated with an adsorbent, activated carbon, after a hydrogen purification process in the production of caprolactam from organic compounds.
П р и м е р. В сточные воды внос т адсорбент (соотношение 10:1), перемешивают и выдерживают 12 ч. Затем определ ют цветность и химическое поглощение кислорода ХПК. Сравнительные результаты по удельной поверхности исходного активированного угл и отработанного приведены ниже:PRI me R. An adsorbent (10: 1 ratio) is introduced into wastewater, mixed and kept for 12 hours. Then the color and chemical oxygen uptake of COD are determined. Comparative results for the specific surface area of the original activated carbon and the waste are given below:

Уголь активированный БАУ720 Уголь активированный БАУ после очистки водорода870 В таблице приведены результаты очистки сточных вод красильного производства. Полученные данные показывают эффективность и рациональность использовани отработанного активированного угл дл снижени цветности и ХПК сточных вод красильного производства.Coal activated BAU720 Coal activated BAU after purification of hydrogen870 The table shows the results of wastewater treatment dye production. The data obtained show the efficiency and rationality of the use of spent activated carbon to reduce color and COD of wastewater from the dyeing industry.
