Abstract:Considering the fact that there is much coal ash in the municipal solid waste (MSW) in some cities of China, the feasibility of composting in this situation was studied and the effect of content of the coal ash on the composting process and some basic relative technological parameters were investigated. The values of the moisture, the total organic matter, the content of coal ash, the C/N ratio and the ventilation were suggested to be 50%-60%, 40%-60%, 40%-60%, (25∶1)-(35∶1) and 0.05-0.20m3/(min·m3), respectively.

 

Key words:   coal ash; municipal solid waste; composting; technological parameters
