(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД(54) METHOD FOR CLEANING WASTE WATER

1one

Изобретение относитс  к очистке сточных вод, содержащих ограниченно растворимые в воде углеводороды (алкибензолы , масла, нефтепродукты), суспендированные гидроокиси металлов красители, и может быть использовано на машиностроительных заводах, в производствах гальваники и некоторых ПАВ.The invention relates to the treatment of wastewater containing limited water-soluble hydrocarbons (alkyl benzenes, oils, petroleum products), suspended metal hydroxide dyes, and can be used in engineering plants, in the production of electroplating and some surfactants.

Такой сложный состав имеют сточны воды производства сульфанола НП-3, получаемого алкилированием бензола в присутствии катализатора-хлоралюминиевого комплекса. В состав сточной воды входит до 80 г/л нефтепродуктов до 15 г/л гидрохлорида алюмини j до 4 г/л бензола; до 20 мг/л сульфанола НП-3.Such a complex composition has waste water from the production of NP-3 sulfanol, obtained by the alkylation of benzene in the presence of a catalyst for the chloro-aluminum complex. The composition of waste water includes up to 80 g / l of oil products up to 15 g / l of aluminum hydrochloride j up to 4 g / l of benzene; up to 20 mg / l NP-3 sulfanol.

Наиболее близким к предлагаемому  вл етс  способ очистки сточнь х вод процесса получени  сульфанола НП-3.The closest to the present invention is the wastewater purification process for the NP-3 sulfanol production process.

Технологическа  схема очистки включает в себ  р д нефтеловушек, отстойники с внутренним обогревом емкостью 400 и 300 м шламоотстойник, выпарную установку. Сточ1ме воды нейтрализуют 5-10%-ньгм раствором кальцинированной соды, затем методом отстаивани  в течение 2-3 недель отдел ют нефтепродукты и гидроокись алюмини , после чего с помощью острого пара отгон ют в атмосферу бензол П. Однако вместе с очищенной водой в водоем сбрасывают до 0,5-1,2 г/л The technological scheme of cleaning includes a number of oil traps, sedimentation tanks with internal heating with a capacity of 400 and 300 m sludge trap, an evaporation plant. The water is neutralized with a 5-10% solution of soda ash, then oil and aluminum hydroxide are separated by settling for 2-3 weeks, and then benzene P is distilled into the atmosphere with hot steam. However, it is discharged into the pond with purified water up to 0.5-1.2 g / l

0 соединений алюмини , до 150 мг/л нефтепродуктов , до 20 мг/л сульфанола. Концентрации указанных токсичных соединений во много раз превышают ПДК на биологическую очистку, а отгонка 0 aluminum compounds, up to 150 mg / l of petroleum products, up to 20 mg / l of sulfanol. The concentrations of these toxic compounds are many times higher than the MPC for biological treatment, and distillation

5 бензола с острым паром значительно удорожает процесс.5 benzene with live steam significantly increases the cost of the process.

Цель изобретени  - повьпиенне степени очистки и упрощение процесса.The purpose of the invention is the degree of purification and simplification of the process.

Поставленна  цель достигаетс  тем, что согласно способу обработку сточной воды ведут методом ультрафильтрации с циркул цией рабочего раствора .The goal is achieved by the fact that according to the method, waste water is treated by ultrafiltration by circulating the working solution.
