Research on Feasibility of Mesophilic Anaerobic Digestion of Mixture of Grass Cutting’s from Greenings and Sludge from Waste Water Plants

Abstract

This paper studies the feasibility of joint digestion processing of grass cuttings from city greening and sludge from waste water plant and selects 10%, 20%, 30%, 40% and 50% dry weight percent for grass cutting’s and sludge. The experimental results indicate that the gas production rate of the sludge digestion system will grow with growth of added grass… (More)
