- Abstract:
- The outlet of urban sludge treatment products has always been a hot issue in the drainage industry. Based on field survey data of regulations, policies and application cases of sludge products in Denmark and Norway, and comparing the current situation of sludge land use management in China, this paper puts forward some enlightenment and thoughts on the land use of sludge products in China, with a view to providing reference for the development and practice of sludge products land use in China in the future. The result shows that Norway and Denmark had established top-down management regulations for the resource utilization of urban sludge products. As an organic nutrient resource, sludge products that met the national regulations are regularly recycled between producers and customers, which not only reflected the value attribute of resources, but also prevented environmental safety problems caused by improper disposal. However, the land use of sludge products is still in the development stage in China. China should strive for policy support in specific practice, improve practical and effective management laws and regulations from top to bottom, realize closed-loop management, and actively encourage and guarantee land use practices. Firstly, we should strengthen source control, continuously carry out sludge testing and form a top-level product quality management system. Secondly, we should understand the attributes of sludge resources through the principles of soil and fertilizer, and develop land use scientifically. Thirdly, we should innovate cooperation mode and strengthen the promotion of land use of sludge products according to the needs of customers.
