PROCESS FOR REVERSE-CURRENT STAGED ADSORPTION TREATMENT OF WASTE WATER FROM SURFACTANTS IN HIGH CONCENTRATIONS AREA

摘要

The invention relates to the use of slag sorbents in reverse-current staged adsorption treatment and can be used on enterprises at treatment of waste water from surfactants in the high concentration area. A process for reverse-current staged adsorption treatment of waste water from surfactants is carried out in adsorbent cascade by removal of reverse-current waste water and adsorbent, and as adsorbent of surfactants dump metallurgic slags are used. The invention provides the realization of closed cycles of water consumption at extraction of surfactants from waste water at the level of their high concentrations and return of purified water to technological cycle, increasing of economic effectiveness of the process by decreasing of costs to purchase of expensive sorbents, solving of ecological problems of industrial regions at development of slag dumps and use of metallurgic slags with utilization of the spent slag in road branch.
