Domestic Solid Waste Landfills: Experimental Analysis of Leachate Stripping Technique

[摘要] The domestic solid waste (DSW) landfills activity is based on the natural processes of organic substances decomposition through their processing into other substances by micro-organisms. Such micro-organisms can only live in water or, in other words, they exist only in the aquatic environment, both in natural environment and under artificial conditions, e.g. in DSW landfill sites. This paper investigates the problem of DSW landfills leachate preparation for the reuse as irrigation water. Leachate is formed as an inescapable side-product of DSW landfills operation. Leachate is a result of precipitations and artificial irrigation contaminated by substances of microbiological decomposition and destruction of organic substances coming to landfill sites as domestic solid waste. The use of leachate as irrigation water will significantly change the DSW decomposition technology and the safety of landfill sites operations.
