Yangzhou City sludge disposal and resource utilisation phase II project officially started construction on 25 December 2020, with a total investment of 125 million yuan, and two new sludge drying production lines with a treatment capacity of 100 tonnes/day, which are scheduled to achieve continuous trial operation by the end of April this year. After the completion of the project, the sludge treatment capacity will reach 500 tonnes/day, and the annual wet sludge treatment capacity will reach 170,000 tonnes. According to the calculation of resource utilisation, it can save 11,000 tonnes of standard coal per year, and the dry sludge can be mixed with power generation up to 33 million degrees/year, reduce carbon dioxide emission by 29,000 tonnes, and reduce solid waste by 14,000 tonnes, which can really make theSludge Filter PressResourceful use of waste into treasure to achieve green cycle sustainable development.

At the same time, in order to meet the new requirements of the national environmental protection, the second phase of the project on the production process of the tail water system has also been improved to ensure that the sludge internal cycle digestion, to achieve the reception of municipal sludge, environmental protection and safe disposal and discharge of the three "100 per cent".
