摘要
调研了我国重点流域11座城市106座典型污水厂的污泥处理方式、处置途径和技术路线。结果表明,我国重点流域污泥处置方式主要包括填埋、焚烧、建材利用和土地利用。填埋所占比例为53.79%,主要与城市生活垃圾进行混合填埋;焚烧所占比例为18.31%,以电厂协同焚烧为主,单独焚烧所占比例较低;建材利用所占比例为16.08%,主要方式为制水泥和制砖;土地利用所占比例为11.01%,处置方式主要为园林绿化和土地改良。此外,基于调研探讨了我国污泥处理处置发展方向。
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.
