摘要
采用植物纤维性材料作为生物滤池滤料,接种人工培养的芽孢杆菌、酵母菌等14种不同的微生物。以NH3、H2S为检测指标,研究生物滤池脱除生活垃圾恶臭的可行性及其工艺,分析气体流量、进气总量和洗气装置对恶臭气体去除率的影响。实验表明在维持一定恶臭气体进气浓度,气体流量Q≤48m3/h的情况下,生物滤池对恶臭气体具有较高的去除率;对滤料中微生物的分析表明,酵母菌、乳酸菌是生活垃圾脱臭的主要功能菌。
A microbial deodorizaiong system for municipal solid wastes was constructed with a sprinkler column and a biofilter reactor. Natural plant filter material and leca(light weight expended clay aggregate) were selected to pack the biofilter. 14 strains of different microorganisms were inoculated to the biofilter. The odour removal efficiency was analysed with chromotograph. The influence of flow rate, odour concentration and sprinkler on the deodorization was investigated. Results showed the microbial deodorization system had strong ability to remove odour from municipal solid wastes. The functional dominant microorganisms in the biofilter were lactobacillus and yeast.
