Abstract

The invention relates to a process for eliminating ammonia from biochemically prepurified waste water, such as is produced, for example, in plants for thermal processing of coal. The aim of the invention is a process for the substantial elimination of ammonia from waste water (up to residual concentrations < 100 mg/l), without lime or other chemicals having to be added and the solids present having to be eliminated. The essence of the invention is that the treatment of the solid-laden waste water is carried out in the sequence - biochemical pretreatment - thermal expulsion of ammonia - biological secondary purification, where the solids loading is to be up to 5 g/l of waste water and the residual ammonia concentration is to be < 100 mg/l. According to the invention, this is achieved in that the outlets of the biochemical pretreatment, without separation of biomass, are transferred into a stripping column and are deammoniated by thermal treatment, specially designed packings being used, which prevent a deposition of solids because of their geometrical form and surface property. Areas of application are all those where the object exists of eliminating thermally expellable ammonia from solids-laden biochemically pretreated waters.

A process for the removal of ammonia from industrial wastewater, obtained primarily from the thermal treatment of coal, characterized in that the wastewater treatment is carried out by bio-chemical pretreatment, by the thermal discharge of ammonia and by the subsequent biological treatment, the contaminated waste water being treated with high concentrations of solids after the biochemical release of bound ammonia lead directly to the thermal flow of ammonia, whereby the free ammonia concentration of natSIOO mg / l is reduced by thermal run-off of the ammonia. 2. Způsob podle bodu 1, vyznačující se tím, že se odtékáníčpavku provádí při koncentraci pevných látek v odpadníchvodách do 5 mg sušiny v litru. 5· Způsob podle bodu 1, vyznačující se tím, že tepelné odtěkání čpavku se provádí v koloně, jejíž neuspořádaná náplňje tvořena geometricky a povrchově strukturně tak, že sejejí pomocí předchází usazování biomasy a neuspořádanánáplň se provede výhodně z nekovových materiálů, napříkladz polypropylenu.2. Process according to claim 1, characterized in that the effluent is discharged at a solids concentration in the effluents of up to 5 mg of dry matter per liter. 5. A process according to claim 1, wherein the heat-dissipating ammonia is carried out in a column whose non-ordered filling is geometrically and surface-structured so as to prevent deposition of the biomass and to arrange the filler preferably from non-metallic materials such as polypropylene.
