Abstract

 Abstract — The effect of anaerobic co-digestion (ACoD) of winery solid waste (WSW) and Zebra manure (ZM) on the enhancement of biogas production was investigated. Biogas was produced by means of an automated single batch anaerobic digester equipped with a pH and temperature control. The fermentation of WSW and ZM was conducted as mono anaerobic digestion (MAD) separately as well as ACoD (1WSW: 2ZM) at 37°C for 30days. Gas production was predicted using Gompertz Model (GM) and Logistic Equation (LE) and measured through downward displacement of acidified water. Results showed the ACoD (1WSW: 2ZM) method produced higher amount of cumulative biogas (952.6mL) as compared to MAD with 30.4mL for WSW and 139.9mL for ZM respectively, after 30 days of retention time. A close fit between the predicted and measured biogas values was observed with correlation coefficient of 0.965 and 0.953 for GM and LE model respectively. Hence, the models can be used to predict biogas yields from ACoD of biodegradable organic waste and ZM. The findings showed the effect of combining WSW with ZM, which could provide essential information and direction for scaling up of biogas production by high-performance ACoD

基于改进Gompertz模型(GM)和Logistic方程(LE)的酒庄固废与斑马粪便共消化产沼气预测

摘要-研究了厌氧共消化(ACoD)对葡萄酒固体废弃物(WSW)和斑马粪便(ZM)提高沼气产量的影响。沼气是通过配备pH和温度控制的自动化单批厌氧沼气池生产的。将WSW和ZM分别以单厌氧消化(MAD)和ACoD (1WSW: 2ZM)的方式在37℃下发酵30d。采用Gompertz模型(GM)和Logistic方程(LE)预测产气量，并通过酸化水向下驱替测量产气量。结果表明，经过30 d的发酵，ACoD (1WSW: 2ZM)法的累积沼气产生量(952.6mL)高于MAD, WSW为30.4mL, ZM为139.9mL。GM模型和LE模型的预测值与实测值拟合较好，相关系数分别为0.965和0.953。因此，该模型可用于预测可生物降解有机废物ACoD和ZM的沼气产量。研究结果表明，WSW与ZM相结合的效果，可为高效ACoD扩大沼气生产规模提供重要信息和指导

期刊介绍： Střed | Centre is a peer-reviewed journal focused on studies of the society, culture and politics in Central Europe of the 19th and 20th centuries. The journal is ecumenical in its selected methodological and disciplinary approaches and strives to give space to scholars working on the broad field of social sciences and humanities, who are involved in studies of the given period and geographical area. Střed /Centre aims at interconnecting the extensive and simultaneously rather fragmented field of research dedicated to Central Europe from the viewpoint of various disciplines. Therefore it publishes original studies from individual fields, particularly studies with the ambition to step over the border defined by disciplinary divisions and to connect more disciplines in a productive dialogue. As a peer-rewieved journal Střed | Centre was founded on January 1, 2009 and is issued twice a year. It is oriented on monothematic issues presenting inter-related scientific essays. Topics of individual issues are published on the journal web page well in advance. Střed | Centre comes out twice a year, in April and October, and is included in the list of peer-reviewed non-impact periodicals issued in the Czech Republic.
