EVALUATION OF STABILITY AND MATURITY PARAMETERS IN WASTEWATER SLUDGEn COMPOSTING WITH DIFFERENT AERATION STRATEGIES AND A MIXTURE OF GREENn PLANT WASTES AS BULKING AGENT

摘要

The aim of this study was to investigate the influence of bulking agent volumetric ratio on the stability and maturity parameters in composting process of anaerobically digested sludge (ADS) with different aeration strategies. Two main influencing factors including aeration method (aerated static pile and windrow process) and proportion of green plant wastes (GPW) and ADS (1:1,2:1 and 3:1, GPW: ADS) were investigated through the evaluation of physicochemical and biological parameters during the
