臭氧对剩余污泥的破解效果研究
A Study on Effect of Ozonation Disintegration for Excess Sludge
摘要
Abstract
Static tests were carried out to study the effect of ozonic disintegration characteristics on waste activated sludge in laboratory.The results showed that ozone improved the effect of sodium hydroxide with increasing oxidizing time at different levels.A substantial increasement in the concentration of protein and UV254 were observed.The concentration of protein increased to 56.3 mg/L and had a largest increase of 40.81% with 30-minute ozonation.Meanwhile,UV254 was 46.21%more than the raw samples.The pH value reduced gradually with the increase of the ozone dose.The microscopic analysis and the particle size assay also showed that ozone favored the destruction of the activated sludge flocculate structures,re-duced and disrupted the crystal size.关键词
