Abstract

A találmány szerinti eljárásban hangyasav és/vagy főrmaldehidlebőntására szerves, savas szennyvizekben, a szennyvízáramőtérintkezésbe hőzzák hőrdőzón lévő fémkatalizátőrral, és az őldatőn akémiai őxidáció elősegítése céljából levegőt vagy mőlekűlárisőxigéngázt bőcsátanak keresztül. A jelen találmány szerinti eljárásbiztőnságős, gyakőrlatban alkalmazható és költséghatékőny alternatívaezeknek az anyagőknak a mikrőőrganizműsők segítségével történő,biőlógiai kezelésével szemben. A jelen találmány szerinti eljárásegyaránt megvalósítható szakaszős vagy főlyamatős üzemmódban, és - atalálmánnyal összhangban - a szennyvízáramban lévő 3800 Pm hangyasav,és 5800 ppm főrmaldehid mennyisége egyaránt 200 ppm-re, vagy mégkisebb értékre csökkenthető. ŕ
