响应面法优化干清猪粪半干法连续厌氧发酵试验参数
Optimization of the Continuous Anaerobic Fermentation Experiment Parameters of Semi-dried Pig Manure by Using Response Sur-face Method
摘要
Abstract
In order to realize the continuous and efficient anaerobic fermentation of dry pig manure,the continuous anaerobic fermentation test was carried out with dry pig manure as raw materials.The effects of hydraulic retention time(HRT),stirring interval and stirring speed on the continuous anaerobic fermentation of dry pig manure were studied by using the self-made continuous anaerobic fermentation reactor in the labo-ratory.The response surface analysis method was used to optimize the experiment parameters,and the optimal parameter combination was ob-tained as follows:HRT 19 d,stirring interval 2 h,and stirring speed 30 r/min.The average daily gas yield was up to 23.48 L after the continu-ous anaerobic fermentation test of dry pig manure.VS degradation rate was 56.47%,and the average volumetric gas production rate was 2.35 L/(L·d),which could achieve efficient and stable operation of dry pig manure continuous anaerobic fermentation.Therefore,the harm-less treatment of dry pig manure could be operated by semi-dry continuous anaerobic fermentation,so as to realize the resource utilization of dry pig manure.关键词
