Abstract:
The comprehensive management of organic urban solid waste is a concern due to its direct and indirect impact on the environment. Anaerobic Digestion (AD) has been recognized as an alternative and environmentally friendly technology for waste disposal, converting them into organic fertilizers and renewable energy. This research presents an experiment involving four reactors fed with household organic waste, three inoculated with canine, goat, and rabbit manure, and one without inoculum. The experiment was observed for 30 consecutive days to analyze the pH and temperature parameters involved in the AD process in domestic reactors. Statistical methodology, including one-way analysis of variance for assessing the effect of the type of inoculum, Tukey\'s simultaneous confidence intervals for mean differences, and 90 % confidence intervals for μ in temperature and manure, was utilized. Additionally, main effects analysis of the factors of average temperature and pH were conducted. The results of the one-factor experiment show that the type of inoculum does not significantly influence the variation in pH, while temperature remains relatively stable throughout the AD process. However, the analysis of main effects indicates that goat manure tends to stabilize the temperature with minimal variation, whereas variation is more heterogeneous in the other experiments.
摘要:
有机城市固体废物的综合治理由于其对环境的直接和间接影响而备受关注。厌氧消化(AD)已被认为是废物处理的替代和环保技术,将它们转化为有机肥料和可再生能源。这项研究提出了一项实验,涉及四个装有家庭有机废物的反应器,三个用犬科动物接种,山羊,和兔子粪便,还有一个没有接种疫苗。连续30天观察实验以分析家用反应器中AD过程中涉及的pH和温度参数。统计方法,包括单向方差分析,以评估接种物类型的影响,Tukey对平均差异的同时置信区间,以及温度和粪便中μ的90%置信区间,被利用。此外,对影响平均温度和pH值的主要因素进行了分析。单因素实验结果表明,接种物的种类对pH的变化没有显著影响,而温度在整个AD过程中保持相对稳定。然而,对主要效应的分析表明,羊粪趋于稳定温度,变化最小,而在其他实验中,变异更为异质。
