- 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.
