Abstract

Abstract

In a small-scale experiment, four groups of self-made composting reactors were used to explore the effect of compound microbial agents on the aerobic biological treatment process and composting effect of food wastes. Using sawdust as an auxiliary material, the heterotrophic bacteria from BIOFORM ^® Waste Digester (WD), the composite thermostable bacteria screened and prepared in previous study (TB), and the mixture of WD+TB were added separately. The no bacteria group was selected as the control (CK). The total weight of pile, temperature, moisture, organic matter content of dry matter, pH value and seed germination index (GI) were determined to study the treatment process. The results showed that when the initial moisture content, organic matter content of dry matter, C/N, amount of auxiliary materials (weight ratio of food waste) and amount of bacteria were (63.5±0.5)%, (96.6±0.9)%, 34.9±2.7, 20% and 25 mL/kg respectively, (WD+TB) group had the longest high temperature period and the highest temperature peak. During the 15-day trial period, (WD+TB) group performed best in terms of total weight loss rate (80.7%), the organic matter loss rate (64.3%) and the daily mean organic matter reduction rate (2.13 times of CK), with the lowest water soluble ammonia nitrogen content and E4/E6, and the highest germination rate index (96.3±26.7)%. This composite microbial agent (WD+TB) could effectively improve the aerobic biological treatment effect of food waste and significantly improve the composting efficiency.
