我國重點流域典型污水廠污泥處理處置方式調(diào)研與分析
- Title:
- Investigation and Analysis on the Treatment and Disposal Methods of Typical Sewage Treatment Plant Sludge in China’s Key River Basins
摘要:- 調(diào)研了我國重點流域11座城市106座典型污水廠的污泥處理方式、處置途徑和技術(shù)路線。結(jié)果表明，我國重點流域污泥處置方式主要包括填埋、焚燒、建材利用和土地利用。填埋所占比例為53.79%，主要與城市生活垃圾進行混合填埋；焚燒所占比例為18.31%，以電廠協(xié)同焚燒為主，單獨焚燒所占比例較低；建材利用所占比例為16.08%，主要方式為制水泥和制磚；土地利用所占比例為11.01%，處置方式主要為園林綠化和土地改良。此外，基于調(diào)研探討了我國污泥處理處置發(fā)展方向。
Abstract:- This work investigated the sludge treatment methods, disposal pathways and technical routes of 106 typical sewage treatment plants in 11 cities located in China’s key river basins. The results show that the disposal pathways of sludge in China’s key river basins included landfill, incineration, building materials utilization and land utilization. The proportion of landfills was 53.79%, mainly mixed landfilling with urban household waste. The proportion of incineration was 18.31%, and coordinated incineration in power plants was the main method, while the proportion of separate incineration was relatively low. The proportion of building materials utilization was 16.08%, and the main ways of sludge utilization were cement making and brick making. And the proportion of land utilization was 11.01%, while the main disposal modes were landscaping and land reclamation. In addition, the development direction of sludge treatment and disposal in China was discussed based on the investigation.
