临夏某污水厂污泥处置工艺效能分析

Efficiency Analysis of Sludge Disposal Process in a Sewage Plant in Linxia

污水处理过程中排出大量富含氮磷等营养元素的污泥,该污泥既是污染物又是一种资源。实现污泥的资源化,对环境生态效益有着重要意义。阐述了传统污泥处理工艺的不足之处,并介绍了复合好氧微生物发酵污泥处置工艺的设计特点及效果。这一工艺有利于提升城市污水处理厂剩余污泥处理质量,实现剩余污泥无害化、资源化和生态化。

Sludge rich in nutrients such as nitrogen and phosphorus is discharged during sewage treatment,which is not only a pollutant but also a resource.It is of great significance to realize sludge recycling for environmental and ecological benefit.The disadvantages of traditional sludge treatment technology were described,and the design characteristics and effects of composite aerobic microbial fermentation sludge treatment technology were introduced.This process is beneficial to improve the treatment quality of residual sludge in municipal sewage treatment plants,and realize the harmless,resource and ecological utilization of residual sludge.
