| dc.description.abstract | Residual waters contg. organic substances, expressed as CCOOr 15000-50000 mg/l, are treated, at 40-80 deg.C, with 0.15-1 mol urea and 0.15-1 mol HCHO. The urea HCHO ratio is 1:1 to 1:2. The resin formed is sepd. by filtration or sedimentation. The treated water is neutralized at pH 0.2-0.5 and then purified biologically. | en_US |
