| description | The invention relates to a process for treating effluents which contain dissolved or dispersed organic or inorganic substances. It is characterised by (A) mixing the effluent with one or more inorganic or organic substances inducing thixotropy, preferably with homogenisation, and (B) sorption of the mixture onto an inorganic or organic natural or synthetic sorbent. During sorption, aeration is advantageously simultaneously carried out. The mass ratio of mixture from step A to sorbent is 2 to 12:1 and advantageously 8 to 10:1. Suitable substances inducing thixotropy are derivatives of polyacrylic acid or polysaccharides and derivatives thereof, in addition in- organic substances such as bentonites, zeolites, clays or power station fly ashes. Expedient sorbents are cereal straw, maize panicles, disintegrated wood mass or municipal wastes or alternatively bentonites, zeolites, clays or power station fly ashes. |
