调控胶冻样类芽孢杆菌添加量对工业堆肥效率与污染物去除的影响
The Addition Amount of Paenibacillus Mucilaginosus Regulates the Maturity Efficiency of Industrial Composting and Pollutant Removal
摘要
Abstract
In this study,the effects of different additions(0％,0.1％,1％and 5％)of Paenibacillus mucilaginosus liq-uid microbial agent on the maturation process and pollutant removal of compost were investigated using chicken manure and spent mushroom substrate as raw materials in an industrial-scale strip-stack composting system.The effects of bacterial agent additions on the composting effect were evaluated by monitoring the temperature,water content,pH,electrical conductivity(EC),organic matter,nitrogen form change,seed germination index(GI)and antibiotic degradation during the compos-ting process.The results showed that the addition of 1％inoculants(T2 treatment)significantly promoted the composting process,warmed the heap earlier(up to 50 ℃ on day 4),and extended the high temperature period to 32 d(5 d longer than the control).Meanwhile,the compost decayed best under this treatment,with seed germination index as high as 88.19％.In terms of pollutant removal,the 1％inoculants treatment was most effective in removing tetracyclines(93.33％degradation of Oxytetracycline)and sulphonamide antibiotics(98.57％degradation of Sulfadiazine).The present study confirmed that 1％addition of Paenibacillus mucilaginosus could optimise industrial composting efficiency and enhance pol-lutant removal,providing technical support for livestock and poultry manure resource utilization.关键词
