摘要:

【目的】 筛选降解奶牛场粪污水的微生物,为奶牛场粪污处理提供科学依据。【方法】 选择可用于降解污水的微生物菌株,测定微生物处理奶牛场粪污水后的化学需氧量(COD)、生物需氧量(BOD5)、总磷(TP)和pH的数值。【结果】 从具有降解污水功能的微生物中,筛选出降解效果较好的3株好氧微生物,分别为枯草芽孢杆菌、巨大芽孢杆菌、胶质芽孢杆菌;3株厌氧微生物,分别为沼泽红假单胞菌、荧光假单胞菌、沙雷氏菌;将6种好氧-厌氧菌耦合处理降解奶牛场粪污水,其降解效率均有不同程度的提升,好氧-厌氧耦合法处理奶牛场粪污水的工艺参数为菌种接种量5%、曝气量0.05 m3/h(每隔10 h曝气2 h)、温度30℃、处理时间96 h。【结论】 奶牛场污水中COD去除率为91.38%、BOD5去除率为96.82%、TP去除率为82.6%,出水pH值为 7.2~7.6,符合国家农田灌溉水标准。

Abstract:

【Objective】 To screen the microorganism that degrades the dariy manure sewage in the hope of providing the scientific basis for the dairy manure treatment.【Methods】 The microbial strains that were reported using to degrade sewage and determine the values of COD(chemical oxygen demand),BOD5 (biological oxygen demang 5 days),TP(total phosphorus)and pH after processing the dairy farm sewage by microorganisms were selected.【Results】 Three strains of aerobic bacteria were screened from the reported beneficial microorganisms that could be used for the treatment of dairy farm sewage,which were Bacillus subtilis,Bacillus megaterium and Bacillus mucilaginous;There were 3 strains of anaerobes,including Rhodopseudomonas palustris,Pseudomonas fluorescens and Seratia marcescens.The best technological conditions for the treatment of dairy farm sewage by the aerobic - anaerobic coupling method were established:5% inoculum,0.05 m3/h aeration(2 h aeration every 10 h),30℃ and 96 h treatment time.【Conclusion】 The removal rate of COD, BOD5 and TP in the dairy farm sewage is 91.38%,96.82% and 82.6%, respectively,and the effluent pH is 7.2-7.6,which conforms to the national standard for farmland irrigation water.
