不同菌丝球的生长、理化特性及污泥负载性能研究
Study on the growth,physicochemical properties and sludge loading performance of different mycelium pellets
摘要
Abstract
Under the same conditions,five strains of Aspergillus Niger 557,Aspergillus Niger Y3,P.chrysospora 507,Aspergillus Niger XX and Aspergillus oryzae F93 spore suspensions were used to culture mycelium pellets.And the growth characteristics,apparent morphology,EPS content,three-dimensional fluorescence spectrum and other physicochemical properties of different kinds of mycelium pellets were investigated.The results showed that the optimal growth time for different kinds of mycelium pellets was 84h,while there were significant differences in the growth amount,particle size,length and internal structure of different kinds of mycelium pellets under the same culture conditions.The total size of mycelium pellets of Aspergillus Niger type was better.Although Aspergillus Niger 557 and XX mycelium pellets had larger particle sizes(about 4mm and 5mm,respectively),and their surface mycelia were 2000～3000μm long,Aspergillus Niger 557 and Y3 mycelium pellets showed better performance as biomass carriers of activated sludge system based on the biomass,structure,characteristics of external mycelia,EPS content and sludge loading performance.关键词
