Abstract

Abstract

In order to improve the fermentation efficiency of vegetable waste and reduce the emission of odor to determine the optimal carbon nitrogen ratio of aerobic fermentation. Aerobic fermentation was carried out with vegetable waste as the main material, and pig manure and corn straw as the auxiliary materials. Three C/N ratios (20, 25 and 30) were set to investigate their effects on maturity and odor emission concentration of fermented products. Temperature, moisture content, pH, electrical conductivity (EC), E4/E6, seed germination index and total nitrogen, total phosphorus and total potassium content were used to evaluate the maturity of fermented products. The results showed that: in T1 treatment (C/N=20), the longest duration of high temperature period was 6 days, the seed germination index was up to 82.23%; then its maturation effect was the best, and the content of total nitrogen, total phosphorus and total potassium were increased by 24.22%, 78.94% and 51.45% respectively. In terms of odor emission concentration, the highest emission concentration of NH₃ appeared in T2 (C/N=25) treatment group, 368000 μg/m³, the highest emission concentration of H₂S appeared in T3 (C/N=30) treatment group, 671 μg/m³; the highest TVOC emission concentration appeared in T1 treatment group, but the maximum difference of TVOC emission concentration between all groups was only 4.3 ppm. Therefore, it was suggested that the optinum C/N ratio of vegetable waste, pig manure and corn straw combined with aerobic compost was 20, which could meet the requirements of harmless aerobic fermentation and reduce the emission of odor.
