污泥造粒颗粒好氧培养特性研究
Study on Aerobic Culture Characteristics of Sludge Granulation Particles
摘要
Abstract
In order to explore the change ofmorphology,particle size,water content,sludge settling ra-tio in aeration in(SV),sludge volume index(SVI),the solid content of suspended solids(MLSS) of the sludge granule in the aeration process,the activated sludge in the sewage treatment plant was used as ma-terial to carry out artificial granulation and aerobic culture for granulation particles.The results showed that:in 20 days of incubation,the size of sludge particle increased from 450.21 μm to 598.60 μm and MLSS from 5 373.01 mg/L to 5 576.02 mg/L,SV decreased from 24.31% to 19.31%,SVI from 45.23 mg/L to 37.41 mg/L,and moisture content from 96.10% to 95.19%.It shows that the stability of sludge granulation particles in the aeration process is enhanced.关键词
