Claims (2)

1. Способ очистки технологических сточных вод, содержащих диметилацетамид и/или другие органических примеси, включающий фильтрование обрабатываемой воды через активированный уголь и регенерацию активированного угля потоком десорбента, отличающийся тем, что обрабатываемую воду предварительно делят на очищенную воду (пермеат) и концентрат методом баромембранного разделения с последующим фильтрованием уже одного концентрата через активированный уголь с дальнейшей регенерацией активированного угля потоком десорбента и выделением диметилацетамида и/или других органических примесей в концентрированном виде.1. The method of purification of technological wastewater containing dimethylacetamide and / or other organic impurities, comprising filtering the treated water through activated carbon and regenerating the activated carbon by a desorbent stream, characterized in that the treated water is preliminarily divided into purified water (permeate) and concentrate by the baromembrane separation method followed by filtration of already one concentrate through activated carbon with further regeneration of activated carbon by a desorbent stream and the release of dim ethyl acetate and / or other organic impurities in concentrated form. 2. Способ по п.1, отличающийся тем, что в качестве десорбента используют горячий азот.2. The method according to claim 1, characterized in that hot nitrogen is used as a desorbent.
