    处理农村生活垃圾装置的研制及工艺

    Composting equipment design and technology for rural refuse disposal

    • 摘要: 为了探索农村生活垃圾的处理途径,该文研究了一种新型一体化处理生活垃圾的装置及工艺,以广州市番禺区猛涌村生活垃圾为研究对象,进行了2个月的中试试验。研制的堆肥装置分4个小仓,每个小仓容纳垃圾1.56 m3,总容积6.24 m3,抽风机功率为1.1 kW/h,抽风频率为1 d 10次,每次30 min,总时间为5 h,每天总耗电量5.5 kW,能耗低。通过12 d高温发酵,24 d编织袋二次发酵的处理方式,温度能达到60℃的天数在5 d以上,出仓时减容约为40%,堆肥产品质量符合要求,且整个处理过程无二次污染,结果表明该装置及工艺可以用来处理农村生活垃圾,可充分做到垃圾减量化、无害化和资源化。

       

      Abstract: 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.
