The environmental risk caused by the rural refuse increasingly is proved to be a big issue because there is not enough place for landfill.A new kind of composting equipment and technology was studied for dealing with such a problem in this paper.The composting equipment,which is composed of 4 bins with 1.56 m3 volume of each bin,was tested for 2 months at the municipal solid waste transfer station at Mengyong village,Panyu district in Guangzhou.The power of exhaust fan was 1.1 kW/h,the operation frequency was 10 times per day,30 minutes per time,so the total operation time was 5 hours a day,the energy cost of the whole compost was 5.5kW.Through 12 days of high temperature fermentation followed by 24 days of bag fermentation,the temperature could be up to 60℃ for at least 5 days,the volume reduction rate of the rural refuse could reach up to 40% after 12 days,and there was no secondary pollution in the whole compost.The results showed that the composting equipment and technology was a feasible way to realize quantitative reduction,harmlessness and resources recovery of the rural refuse.
