Abstract:Purpose: In order to solve the problem of endogenous pollution mainly caused by sediment, engineering measures such as dredging and dredging have been widely applied in water environment management projects such as rivers, lakes, and reservoirs. At present, the amount of sediment generated by dredging and dredging in China is as high as 70 million tons, and it is still growing at a rate of 4% to 6% annually. At the same time, the dual attributes of "pollution" and "resources" of sediment also bring opportunities and challenges for its resource utilization. Method: Therefore, this article systematically reviews the principles, advantages and disadvantages, costs, and future development directions of current sediment resource utilization technology. Result and Conclusion: It is found that sediment resource utilization has involved multiple fields such as ecological restoration, construction, building material manufacturing, energy recovery, and environmental protection materials. In the future, the resource utilization of sediment should be achieved by establishing a sediment database in different zones to improve the accuracy of dredging engineering. Based on this, sediment should be utilized in different zones, layers, and classifications, and resource utilization technologies should be selected according to local conditions; At the same time, it is necessary to optimize the pre-treatment technology of sediment, improve the quality grade of sediment related products, and focus on toxic and harmful substances and new pollutants in sediment to achieve their safe utilization; Finally, we will improve the standard system for the entire process of sediment resource utilization and gradually standardize the market for sediment resource utilization.
