Field studies of leachate from landfilled combustion redidues

Abstract

This paper presents some leachate quality data from two municipal solid waste incenerators (MSWI) ash monofills, a marine land reclamation site containing both MSWI ash and coal fly ash and a parking lot where MSWI bottom ash has been used as sub-base. All the sites are located near Copenhagen, Denmark. The leaching data from the two MSWI ash monofills have been presented previously (1-2) and in this paper they are merely updated with observations from 1989-1991 to cover total periods of 19 and 9 years, respectively. Wherever possible it has been attempted to relate the leachate quality data to the total amount of leachate produced in terms of the liquid/solid ratio. A few results of laboratory leaching tests on MSWI bottom and combined ash are also presented. There is a good general agreement between the field observation and the laboratory results, particularly if the different redox conditions are taken into account. All results show that inorganic salts and organic matter are the major constituents of the initial leachate. Trace metals are generally found in relatively low levels in the leachate. Both field and laboratory results indicate that the content of ammonia in the leachate may remain at a relatively high  More>>

It is recommended that the effort to procure reliable long term observations is increased. (au).}
