Abstract

1462736 Recycling anaerobic process CELANESE CORP 7 May 1975 [9 May 1974] 19176/75 Heading C1C A process for the anaerobic biological treatment of waste water containing organic pollutants which are of such a nature as to be amenable to anaerobic digestion, comprises passing the waste water through an anaerobic digestor or filter containing a biomass consisting essentially of micro-organisms capable of digesting said pollutants while converting the waste water to a purified effluent having a reduced content of said pollutants, wherein a portion of the effluent is recycled to the inlet of the anaerobic digestor filter, and admixed into the waste water entering the digestor filter, in such an amount that the content of the pollutants and any biostatic or biocidal species which are present in the resulting mixture of recycled effluent and waste water is below that level above which there results inhibition of the growth processes of the microorganisms. This may also eliminate or reduce the need for employing additional alkaline reagents to adjust the pH of the waste water prior to treatment, in as much as the effluent commonly contains alkaline bicarbonates (produced in the treatment process) which may not be contained initially in the waste water. Sewage, and in particular industrial wastes containing organic pollutants, such as acetic, formic and acrylic acids, acetaldehyde and acrylate esters from a petro-chemical plant waste water, may be treated.
