Abstract

Inventia se refera la un procedeu pentru epurarea unor ape reziduale industriale continînd poluanti organici ca formaldehida, butanol, izobutanol, metanol, propilenglicol, pentaeritrita, prin tratarea cu un sistem catalitic redox alcatuit din clorura ferica si sulfat feros si sulfat de cupru agitarea sau barbotarea cu aer a apei la temperatura si presiunea mediului ambiant pana la un randament de epurare de 74....81% dupa care sunt trecute printr-o instalatie de epurare de 97.....99% exprimat în sistemul CCO-Cr. Procedeul permite refolosirea catalizatorilor pentru o noua epurare.The invention relates to a process for purifying industrial waste water containing organic pollutants such as formaldehyde, butanol, isobutanol, methanol, propylene glycol, pentaerythritol by treatment with a redox catalytic system consisting of ferric chloride and ferrous sulphate and copper sulphate stirring or bubbling with air of the water at ambient temperature and pressure to a purge efficiency of 74 ... 81%, after which it is passed through a 97 ... 99% purification plant expressed in the CCO-Cr system. The process allows the reuse of the catalysts for a new treatment.
