摘　　要：探明酱酒污泥资源的生物处理法,为酱酒污泥的处理处置和资源化利用提供参考。以纯酱酒污泥、酱酒污泥+秸秆混合物为研究对象,利用大平二号蚯蚓处理纯污泥和污泥秸秆混合基质,综合分析基质的含水率、pH、养分含量和蚯蚓数量及重量等指标差异。研究结果表明:不同处理含水率和第一阶段pH随时间延长呈降低趋势;第二阶段当秸秆比例相同,90%污泥+秸秆组(10%、20%和30%)pH较70%污泥+秸秆组(10%、20%和30%)高;当含水率相同,不同秸秆占比的各处理pH差异不大。不同处理蚯蚓数量随养殖天数的增加而降低,以纯污泥、污泥+10%秸秆、污泥+20%秸秆和污泥+30%秸秆效果好,在第50天分别为67.3、66.5、75.3和64.7条;蚯蚓重量随养殖天数的增加大致呈先升后降趋势,蚯蚓总重量变化呈“∧”形,均以纯污泥、污泥+20%秸秆和污泥+30%秸秆效果好,在第30天达最重,重量分别为0.8781、0.8525和0.8235 g/条;总重量分别为78.1527、79.0027和72.1907 g。用蚯蚓处理后基质的总养分(N+P_(2)O_(5)+K_(2)O)、有机质、总氮、总磷和总钾分别为3.9%~7.2%、38%~63%、2.03%~2.35%、1.67%~2.82%和0.34%~1.89%。因此,利用大平二号蚯蚓处理酱酒污泥养分均满足污泥土壤改良、农用、绿化和有机肥料生产的相关要求,可实现酱酒污泥资源化利用。The biological treatment of Sauce-Flavor Baijiu sludge is explored to provide a reference for disposition and resource utilization of Sauce-Flavor Baijiu sludge.The pure Sauce-Flavor Baijiu sludge and Sauce-Flavor Baijiu sludge+straw mixed substance firstly treated by earthworm and then the differences in moisture content,pH,nutrient content,earthworm number and earthworm weight between pure sludge and mixed substance treatments are analysed comprehensively.Result:The moisture content and pH(at the first stage)of different treatments show the decreasing trend with time extension.The pH of 90%sludge+10%straw(B 6),90%sludge+20%straw(B 7)and 90%sludge+30%straw(B 8)treatments is higher than 70%sludge+10%straw(B 2),70%sludge+20%straw(B 3)and 70%sludge+30%straw(B 4)treatments respectively.There is no obvious difference in pH between different straw ratio treatments under the same moisture content.The earthworm number of different treatments decreases with increase of breeding days.The earthworm number of pure sludge(A 1),sludge+10%straw(A 2),sludge+20%straw(A 3)and sludge+30%straw(A 4)can research 67.3,66.5,75.3 and 64.7 after 50d breeding separately.The earthworm weight of different treatments shows a first rising and then decreasing trend with increase of breeding days.The weight per earthworm and total earthworm weight of A_(1),A_(3)and A_(4)is 0.8781 g,0.8525 g and 0.8235,and 78.1527 g,79.0027 g and 72.1907 g respectively.The content of total nutrient(N+P_(2)O_(5)+K_(2)O),organic matter,total N,total P and total K of the substances treated with earthworm is 3.9%~7.2%,38%~63%,2.03%~2.35%,1.67%~2.82%and 0.34%~1.89%after 30d breeding separately.The nutrients of Sauce-Flavor Baijiu sludge treated by earthworm can meet the relative requirement of soil improvement,agricultural utilization,afforestation and organic fertilizer production,which can realize resources utilization of Sauce-Flavor Baijiu sludge.
