有机负荷对餐厨垃圾单相厌氧发酵的影响
Effects of Organic Loading Rate on the Single-phase Anaerobic Fermentation from Food Waste
摘要
Abstract
[Objective] The study aimed to realize the eat hutch refuse resources use provides the basis. [ Method ] The effect of organic loading rate on the single-phase anaerobic fermentation from food waste in pilot scale was studied. [Result]The results showed that pH, ammonia nitrogen and SCOD in the fermentation process remained relatively stable when the organic loading rate was low[0.75-1.25 g/(L·d) ]. At this time, the increasing of organic loading rate helped to improve biogas production and production rate. When the organic loading rate reached a certain height[ 1.50 g/( L·d) ], pH decreased and ammonia nitrogen and SCOD increased. It suggested that processing capacity of the single-phase anaerobic fermentation for food waste was low. Food waste was rich in nitrogen. C/N should be adjusted before fermentation. Methane concentration was 50% -75% , and not affected by organic loading rate. [Conclusion] Low organic loading [0.75 - 1.25 g/(L·d)] was beneficial to the single-phase anaerobic fermentation of food waste.关键词
