本发明公开了一种快速表征堆肥腐熟度的方法，属于固体有机废弃物处理领域。收集1g样品，制备得到堆肥水萃液，测定堆肥水萃液的DOC，并稀释到DOC＜10mg/L，采集稀释后水萃液的三维荧光光谱EEM谱图，采用DOMFluor工具包在Matlab 7.0软件上对采集到的EEM谱图代入数据库进行平行因子分析，确定激发/发射波长为(230，330)/410和(220，280)/340的2个组分的得分数，再将所得得分数乘以样品稀释倍数后代入堆肥腐熟度判别关系式，即可用于表征堆肥腐熟度。

本发明涉及一种快速表征污泥脱水性能的方法，先收集100ml原污泥或浓缩污泥，用0.45μm滤膜过滤得到10mL污泥上清液，测定上清液的可溶性有机碳(DOC)，再用蒸馏水稀释上清液到DOC＜10mg/L，采集稀释后的上清液的三维荧光光谱(EEM)谱图，采用DOMFluor工具包对采集到的EEM谱图代入数据库进行平行因子分析，确定激发/发射波长为(220，280)/350nm组分的得分数，再将所得得分数乘以样品稀释倍数后代入污泥脱水性能判别关系式，即可表征污泥脱水性能。

本发明属于微生物源农药制备领域，提供一种脂肽-高岭土复合生防制剂及其制备方法和应用。该复合生防制剂由脂肽、剥片高岭土和水组成，其中，脂肽和剥片高岭土的质量百分比分别为0.1％、2％。该脂肽-高岭土复合生防制剂的制备过程包括：(1)脂肽粉末制备(2)剥片高岭土制备(3)脂肽-高岭土复合生防制剂获得。本发明提供的脂肽-高岭土复合生防制剂中，剥片高岭土与脂肽的结合提高了脂肽的稳定性，延长了脂肽的作用时间，有效地提高防治番茄青枯病的防治效果，促进了番茄植株生长。

快速鉴别污水处理厂进水中垃圾填埋场渗滤液的方法，涉及一种快速判断渗滤液是否非法排入污水处理厂的方法。取污水厂剩余活性污泥，离心得上清液，再在激发波长200-500nm，发射波长为250-600nm，狭缝宽度为5nm，扫描速度为1200nm/min下，对样品进行三维荧光光谱测定，得到数值化三维荧光谱图，如样品的荧光峰仅为类富里酸(激发/发射波长＝240/440nm)和类腐殖酸物质(激发/发射波长＝330/420nm)，而无类蛋白质物质，表明污水处理厂进水中存在垃圾填埋场渗滤液。

本发明公开了一种土壤团聚体的分析方法，属于农田土壤肥力提升和土壤有机碳循环领域。该方法首先采集土壤样本；之后将土壤样本进行土壤团聚体筛分预处理，将筛分预处理好的土壤团聚体用水包埋方法进行低温冷冻切片；然后将切片好的样品放在低辐射玻璃(LOW？E)镜片上；最后采用同步辐射红外显微成像技术对步骤的冷冻切片样品进行分析。本发明方法可以准确、高效地探究土壤团聚体稳定机制。同时，该方法探究土壤团聚体稳定机制时，具有扫描速度快(<3h)、重现性好及其可原位探索土壤矿物和有机物等优点。

本发明属于固体有机废弃物资源化利用领域，具体涉及一种沼渣快速堆肥方法及应用。

本发明公开了一种沼渣中重金属移除方法，属于固体有机废弃物资源化利用领域。本发明首先将沼渣与牛粪、秸秆等辅料配比并进行高温好氧发酵；高温好氧发酵后的沼渣再与牛粪配比后进行蚯蚓后腐熟堆肥；蚯蚓后腐熟堆肥后，将富集重金属后的蚯蚓分离，从而达到将沼渣中重金属减量的目的；分离后的蚯蚓进一步通过碱水解、离心沉降去除重金属，而富含氨基酸复合物的上清液可作为液体氨基酸肥农用。本发明可以有效减少沼渣中的重金属含量。同时，本发明对于沼渣资源化利用、生态环境保护，农产品附加值的提高具有重要的意义。
