【摘要】：为受控生态生保系统建立生物可降解固体废物循环系统提供可靠的理论依据,而进行废物处理和就地资源化利用效率,实现生物可降解固体废物可再生利用技术成熟。堆肥通过分析物料物理指标、化学指标及生物指标判断堆肥腐熟程度。首先,为堆肥中微生物提供适宜的生存环境而研制微生物固体废物处理实验装置,筛选出合适的微生物复合菌剂;其次,研究不同物料组合对腐熟度的影响;最后,以不同物料堆肥产品与蛭石按3:1、2:1、1:1、1:2、1:3的比例均匀混合,作为红苋菜栽培基质,通过监测蔬菜生物量、NO3--N及可溶性糖含量等指标,分析不同堆肥产品处理对生物产量和品质的影响。同时选取长势旺盛的栽培蔬菜及其栽培基质进行碳素氮素去向分析。研究结果表明:1.微生物固体废物处理实验装置以月球基地空间站任务为应用背景,能够实现小体积堆肥实验研究及工艺参数设置,装置具有严格密闭性和保温性。2.在接种两种不同微生物复合菌剂的比较实验研究中,VT菌剂和有机肥发酵菌剂均有其不同的优势表现,均能够加速堆肥进程,堆肥周期为20天左右,且种子发芽率均大于100%,具有促进植物生长的能力。有机肥发酵菌剂堆肥产品有机质含量高,营养元素全面,可作为植物栽培肥料使用。3.不同物料组合处理实验中,花生壳添加与否,其处理结果差异不显著,种子发芽率均超过50%,可认为堆肥中几乎没有植物毒性。添加果蔬垃圾的物料处理种子发芽率小于1%,这与堆肥产生大量的有机酸等小分子物质抑制植物生长有关,但果蔬垃圾堆肥有机质含量高,降解快。4.蛭石与有机肥按1:3比例混合的基质肥效试验中,红苋菜生长受到抑制,不利于蔬菜栽培。蛭石与蔬菜垃圾基质按3:1、2:1的比例混合基质肥效实验中,红苋菜长势旺盛,与对照相比较,其株高,根长等生物量指标均很高。
[Abstract]:It provides a reliable theoretical basis for the establishment of biodegradable solid waste recycling system for the controlled ecological conservation system, and carries out the waste treatment and local resource utilization efficiency, and realizes the renewable utilization technology of biodegradable solid waste. Compost judge the composting process by analyzing material physical index, chemical index and biological index. First, to provide the suitable living environment for microbes in the composting, the experimental device for the treatment of microbial solid waste was developed, and the suitable microbial compound was screened out. Secondly, the effect of different material combinations on the maturity was studied. Finally, the different material compost products and the vermiculite were mixed evenly with the 3:1,2:1,1:1,1:2,1:3 ratio as red. Through monitoring vegetable biomass, NO3--N and soluble sugar content, the effects of different composting products on biological yield and quality were analyzed by monitoring the biomass, NO3--N and soluble sugar content of different composting products. The mission of the lunar base space station is the application background, and the experimental research and process parameters of the small volume composting can be realized. The device has strict airtight and thermal insulation.2. in the comparative experimental study of two different microbial compound inoculants. Both the VT and the organic manure fermentation agents have different advantages, and all can accelerate the composting. The course of the composting period is about 20 days, and the germination rate of the seed is more than 100%. It has the ability to promote plant growth. The organic manure composting product has high organic matter content and the nutrient element is comprehensive. It can be used as the plant cultivation and fertilizer in the.3. different material combination treatment experiment, the peanut shell is added or not, the difference of the treatment result is not remarkable. The germination rate of the seeds was more than 50%, and there was almost no plant toxicity in the composting. The germination rate of the seeds treated with fruit and vegetable waste was less than 1%, which was related to the inhibition of plant growth by a large number of organic acids such as organic acids in the composting, but the content of organic matter in the composting of fruit and vegetable waste compost was high, and the mixture of.4. vermiculite and organic fertilizer was mixed in the proportion of 1:3. In the experiment, the growth of amaranth was inhibited and it was not good for vegetable cultivation. In the experiment of the mixture of vermiculite and vegetable waste matrix according to the ratio of 3:1,2:1, the growth of amaranth was strong, and the height and root length of the red amaranth were all high.
