基于CSTR和UASB工艺的沼气工程实例分析
Analysis on Biogas Engineering Based on the Processes of CSTR and UASB
摘要
Abstract
As the techniques of biogas fermentation developed rapidly, relevant processes boomed accordingly. Among these, CSTR and UASB were the most widely used in the biogas engineering due to the advantages of simpleness, convenience and efficiency. In this paper, several typical biogas engineerings based on the processes of CSTR and UASB were analyzed and compared with each other. As concluded by the author, CSTR has unique stirring process, which can treat high-concentration fermentation materials (TS 8% -12% ), and produce the gas largely and uniformly; it also has simple structure , which is easy to be started and managed. It is now used in most advanced countries. Compared with CSTR, UASB occupies little area and needs little investment, it is good to process high-concentration organic wastewater, its retention time is short, most of active sludge concentrates at the bottom, the fermentation effect is remarkable. Based on the features of two processes, they should be flexibly used given local conditions. With the introduction of advanced technology, we should also innovate our own high-efficient biogas engineering technique especially for our country.关键词
