The ' action plan for preventing and treating water pollution ' issued by the state government definitely provides a controllability target of ' controlling black and odorous water bodies in the built-up areas of the cities to be within 10% at grade and above in 2020, and eliminating the black and odorous water bodies in the built-up areas of the cities in 2030. The bottom mud is used as an important component of a river and lake ecological system, is not only a central link of nutrient substance circulation of a water body, but also a main gathering reservoir of nutrients, persistent organic pollutants and heavy metals, and is the most important source for causing water body pollution and ecological system damage. As an important component of a comprehensive treatment system for pollution of water bodies in river and lake ponds, the bottom mud treatment is receiving more and more attention.
The sediment dredging can thoroughly remove pollutants from a water body system, so that the water quality of the water body is improved to a greater extent, the safety of the water body is improved, the ecological system restoration is promoted, the release of endogenous pollutants to an overlying water body is avoided, and the sediment dredging is more and more widely applied in recent years. However, the traditional dredging sediment treatment technology is biased to be extensive, and adopts an undifferentiated treatment means for sediment particles with different particle sizes and organic matter contents, so that the single outlet of sediment products is caused, the yield is huge, meanwhile, the closure of the operation process is poor, and finally, a large amount of land resources are occupied, the ineffective energy consumption of the process is increased, renewable resources are wasted, secondary pollution is increased, and other problems are caused. Research has shown that organic pollutants are mainly concentrated in fine bottom mud particles, but are lower in coarse particles with relatively dense structures, so that bottom mud particles with different particle sizes correspond to different optimal treatment modes.
In summary, the current treatment mode of dredged sediment has obvious blindness and environmental risk, does not meet the essential requirements of green low-carbon technology, and needs to be improved. Under the new background that China vigorously advances the construction of 'waste-free cities' and 'waste-free society', according to the environmental management requirements of solid wastes and by taking organic matter content as a main index, a quantitative reduction and classification treatment device for dredged sediment is developed, so that the device not only can provide necessary technical support for realizing the differential utilization of different beneficial components of the sediment, eliminating the environmental risk hidden danger of the sediment and relieving the supervision pressure of related departments, but also has outstanding practical significance for advancing the ecological civilization construction of China, promoting the high-quality development and realizing the inevitable requirements of comprehensive resource conservation.
