Disposal of seepage water from rubbish dumps

摘要

The sludge gas (1) obtained continuously is used completely in that it is burnt in an internal combustion engine (2) which is coupled to a generator (2'), to generate current. The heat obtained in the course of this serves to heat seepage water in a heat exchanger (5) and the seepage water is evaporated in an evaporation chamber (8) by low-temperature flash evaporation under vacuum. As a result of the flash evaporation, this evaporation plant has considerable advantages over drop-film or thin-film evaporators. The encrustations otherwise usual are avoided.
