温度和水力停留时间对厌氧消化处理葡萄糖合成废水产甲烷动力学的影响
Impact of temperature and hydraulic retention time on the methane production kinetics in anaerobic digestion of synthetic glucose wastewater
摘要
Abstract
The study elucidated the relationship between anaerobic digestion gas production efficiency and temperature and hydraulic retention time(HRT)using synthetic glucose wastewater as a substrate.Gas production under different temperatures(37,55 ℃)and HRTs(25,30,50 d)was compared.The results indicated that the hydrolysis rate of glucose was higher at thermophilic temperature than at mesophilic temperature.However,volatile fatty acids,especially propionic acid,tended to accumulate at thermophilic temperature.Additionally,Methanomicrobiaes and Methanosarcinales were enriched at both moderate and high temperatures,suggesting the presence of pathways for methane production from acetic acid and acetate oxidation at both temperatures,with the acetate oxidation pathway exhibiting greater environmental resilience.The recommended optimal fermentation conditions for treating heavy glucose-containing wastewater through anaerobic digestion are 37 ℃ and an HRT of 30 days.关键词
