农业废弃物资源化梯次利用低碳模式研究石惠娴,沈昊文,潘方慧,朱洪光,王孜竞,周雪飞,张亚雷(同济大学新农村发展研究院/同济大学国家设施农业工程技术研究中心,上海200092)摘要将农业废弃物分为畜禽粪便和农作物秸秆两大类。在参考国内外农业废弃物资源化梯次利用模式的基础上,深入分析安徽阜阳和上海崇明城桥镇农业废弃物资源化利用现状,绘制出区域农业废弃物沼气工程全产业链物质流梯次循环利用和农作物秸秆还田资源化循环利用2个低碳模式图。前者以农业废弃物联合厌氧发酵技术为核心,形成生物天然气能源产业系统,系统内碳、氮、磷营养梯次回收利用、种养结合能肥联产物质资源化循环利用模式;后者综合考虑了秸秆还田的优势和不足,形成了以稻麦轮作秸秆适当还田资源化梯次利用模式。关键词农业废弃物;资源化利用;模式中图分类号X71文献标识码A文章编号0517-6611(2023)03-0209-04doi:10.3969/j.issn.0517-6611.2023.03.048开放科学(资源服务)标识码(OSID):StudyonLowCarbonModeofAgriculturalWasteRecyclingUtilizationSHIHui-xian,SHENHao-wen,PANFang-huietal(InstituteofNewRuralDevelopment,TongjiUniversity/NationalResearchCenterforFacilityAgricultureEngineeringTechnology,TongjiUniversity,Shanghai200092)AbstractAgriculturalwastewasdividedintolivestockmanureandcropstraw.Basedonreferringtotherecyclingutilizationmodelsofagri-culturalwasteathomeandabroad,therecyclingutilizationstatusofagriculturalwasteinFuyangofAnhuiandChengqiaoTown,Chongming,Shanghaiweredeeplyanalyzed,twolow-carbonmodelfiguresofcascadeutilizationofmaterialflowinthewholeindustrialchainofregionalag-riculturalwastebiogasprojectandrecyclingutilizationofcropstrawreturnedtothefieldweredrawn.Thefirstmodelwasbasedonthecom-binedanaerobicfermentationtechnologyofagriculturalwaste,anindustrialsystemfortheproductionofbio-naturalgasenergywasformed,thecascaderecyclingutilizationofcarbon,nitrogenandphosphorusinthesystemandtherecyclingutilizationmodeofenergyandfertilizerproduc-tionmaterialswereformed.Thesecondmodelcomprehensivelyconsideredtheadvantagesanddisadvantagesofreturningstrawtofield,there-cyclingutilizationmodeofreturningrotationstrawofrice-wheattothefieldwasformed.KeywordsAgriculturalwast...
