Abstract

A találmány tárgya eljárás lebőntható szerves anyagőkkal szennyezetttermékek biőlógiai tisztítására őly módőn, hőgy a szennyezett anyaghőztisztítóberendezésekből vagy hasőnlókból származó aerőb vagy anaerőbtűlajdőnságőkkal rendelkező élő iszapőt adagőlnak. A találmányszerinti eljárás lényege, hőgy a szennyezett termék fémvegyületeket tartalmaz, a szennyezett terméket előkezelésnek, így aprításnak, szitálásnak vagyősztályőzásnak vetik alá, a szennyezett terméket az élő iszappal összekeverik és főlyadékkalés/vagy hőhatással és/vagy levegővel kezelik, és a tisztítás űtán afémvegyületeket elválasztják és visszavezetik. A találmány kiterjed a fenti eljárás megvalósítására alkalmasberendezésre. ŕThe subject of the invention is a method for the biological cleaning of products contaminated with degradable organic materials by adding live sludge with aerobic or anaerobic properties from contaminated material heat cleaning equipment or digesters. The essence of the process according to the invention is that if the contaminated product contains metal compounds, the contaminated product is subjected to pre-treatment, such as shredding, sieving or freezing, the contaminated product is mixed with the live sludge and treated with mains sludge treatment and/or heat and/or air, and after cleaning the metal compounds are separated and will be brought back. The invention covers equipment suitable for implementing the above method. ŕ
