摘要
污泥是污水处理净化过程中的必然产物,具有量大、恶臭、易腐败、不稳定等共性,一些工业污泥还含有有毒有害物质,对污泥进行减量化、稳定化、无害化和资源化的处理成为当务之急。目前,污泥资源化利用技术主要有污泥硝化、污泥堆肥、建材利用等,它们的研究和应用有效解决了污泥处理不当造成的环境二次污染问题,促进了污泥处理的规范化、合规化。
Sludge is an inevitable product in the process of sewage treatment and purification,which has the common characteristics of large amount,foul smell,easy corruption and instability,some industrial sludges also contain toxic and harmful substances,and it is urgent to reduce,stabilize,harmless and recycle sludge.At present,sludge resource utilization technologies mainly include sludge nitrification,sludge composting,and utilization of building materials,their research and application have effectively solved the problem of secondary environmental pollution caused by improper sludge treatment,and promoted the standardization and compliance of sludge treatment.
