Determination on Acidification Point during Anaerobic Digestion of Biodegradable Municipal Solid Waste

Abstract:

The aim of this work was to investigate the acid inhibition during the anaerobic digestion of municipal solid waste. Four biodegradable substrates of soybean, fat meat, rice and celery cane were considered in this paper. A series of anaerobic co-digestion tests were performed on the four substrates at the load of 1.0gVS/(L•d) and anaerobic granular sludge. The method to calculate the lowest acidification points of the four substrates was provided by the least squares method, and it is verified by the measured data, and good agreements are achieved.
