“绿色垃圾”低固体浓度厌氧发酵影响研究

Study on the Influence of Low Solid Concentration Anaerobic Fermentation of “Green Waste”

摘要: 随着能源危机问题不断凸显，人们以往忽视的以果蔬垃圾为主的“绿色垃圾”，逐渐成为资源化再利用的热门选择。厌氧发酵技术作为微生物处理的一种方式，可以有效的解决“绿色垃圾”资源化问题。本文综合考虑发酵液浓度、各原料配比对发酵最终产物的影响，通过测定有机质、全氮和有效磷的含量来寻求处理“绿色垃圾”的最佳方案。实验选择微生物兼性厌氧法处理绿色垃圾，以水和土壤为媒介，按照一定比例混合以低固体浓度进行厌氧发酵，研究不同实验条件下，相同原料进行组合配比时厌氧发酵结果的差异性。实验结果显示，当低固体浓度绿色垃圾：土：水比例为2:1:2时厌氧发酵的处理效果最好。

Abstract: With the energy crisis more and more serious, the green waste that consists mainly of fruit and vegetable waste which people have ignored gradually has become a popular choice of beneficial reuse. As a way of microbial treatment, anaerobic fermentation technology can solve the resource problem of green waste effectively. This paper comprehensive considers the influence of end product of fermentation by fermentation broth concentration and various raw material proportions; and we seek the preferred plan dealing with the green waste by measuring the content of organic matter, total nitrogen and available phosphorus. This experiment selected microbial facultative anaerobic method to deal with the green waste, through the medium of water and soil, according to low solid concentration anaerobic fermentation mix in a certain proportion, studying the differences of results of anaerobic fermentation when the raw material mix ratio is same under different experimental conditions. The experimental result shows, when the proportion of green waste, soil and water is 2:1:2, treatment effect is the best.
