摘　　要：为减轻化粪池气味污染,减少化粪池清掏次数,降低化粪池运营成本,制备一种复合微生物菌剂并探究其降解应用效果。以课题组制备的由特基拉芽孢杆菌YZS-C01、沙福芽孢杆菌YZS-C03、粪产碱杆菌QQB-A05和恶臭假单胞菌ZTB-A29制成的复合微生物菌剂(固体制剂和液体制剂)为研究对象,通过测定其固体制剂对粪渣的原位减量以及其液体制剂对臭味去除率,评价其应用效果。结果表明:复合微生物菌剂固体制剂10 d内能使化粪池内浮渣全部沉降,对粪渣的降解率在65%以上,比对照组沉降率和降解率均高出60%以上。复合微生物菌剂液体制剂在喷雾处理化粪池臭味时,氨气和硫化氢即时去除率在85%以上,4 h后氨气和硫化氢去除率仍能保持65%以上,并能促进化粪池内浮渣降解,降解率达60%。研究制备的复合微生物菌剂可同时应用于粪渣原位减量和化粪池臭味去除,为化粪池粪渣原位减量和气味处理生物强化技术提供技术支持。In order to reduce the odor pollution of septic tanks,reduce the number of septic tank cleanings,and reduce the operating costs of septic tanks,a composite microbial agent was prepared and its degradation application effect was explored.The composite microbial agent(solid preparation and liquid preparation)prepared by the research group,which was made of Bacillus tequilensis YZS-C01,Bacillus safensis YZS-C03,Alcaligenes faecalis QQB-A05 and Pseudomonas putida ZTB-A29,was used as the research object.The application effect was evaluated by measuring the in-situ reduction of fecal residue by its solid preparation and the removal rate of odor by its liquid preparation.The results showed that the solid preparation of the composite microbial agent could make all the scum in the septic tank within 10 days,and the degradation rate of fecal scum was above 65%,which was more than 60%higher than the settlement rate and degradation rate of the control group.When the liquid preparation of composite microbial agent was sprayed to treat the odor in septic tank,the instantaneous removal rate of ammonia and hydrogen sulfide was above 85%,and the removal rate of NH3 and H2S could till be maintained above 65%after 4 hours.It could also promote the degradation of scum in septic tank,with a degradation rate of 60%.The composite microbial agent prepared in the study could be used for the in-situ reduction of fecal scum and the removal of odor in septic tank at the same time,providing technical support for the in-situ reduction of fecal scum in septic tank and the bioaugmentation technology for odor treatment.
