我国农村易腐垃圾机器成肥产品质量评价——以杭州市为例
Quality evaluation of mechanical composting products for putrescible wastes in rural areas in China:A case study in Hangzhou
摘要
Abstract
In this study,product qualities of 12 mechanical composting stations for rural putrescible waste treatment in 6 districts(counties or county-level cities)in Hangzhou were investigated.Results showed that pH,moisture content,electrical conductivity(EC),organic mat-ter content,and total nutrient content of the mechanical composting products were 6.4±0.9,29.9%±15.9%,(7.14±2.28)mS·cm-1,74.9%± 14.7%,and 6.16%±1.48%,respectively.The concentrations of As,Hg,Pb,Cr,and Cd in the mechanical composting products were all lower than the maximum values in the standards for "Organic Fertilizer" (NY 525—2012)with the exception of Pb for one station.The maturity indices of the ratio of humic acid to fulvic acid(HA/FA), seed germination rate, and Germination Index(GI)were 0.95±0.41, 36.1%± 40.4%,and(17.8±28.1)%,respectively.These results showed that nearly all the physicochemical properties of the mechanical composting products investigated met the relevant requirements shown in the standard of "Organic Fertilizer" (NY 525—2012), excluding moisture content.However,75% of the composting products from the 12 stations did not meet the basic requirements of the maturity index for organic fertilizer.Therefore,currently,it is of great importance to update the technology for mechanical composting of rural putrescible waste to en-sure that the maturity of its products meets the relevant standard requirements.关键词
