River sludge contains a variety of toxic and harmful substances, which pose a serious threat to the surrounding environment. Among them, toxic and harmful organic matter includes polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins, adsorbable organic halides, etc. At the same time, there are also a large number of parasite eggs, microorganisms, pathogens and heavy metal ions such as cadmium, chromium, copper, zinc, etc.

Due to the presence of these toxic and harmful substances, river sludge can easily cause secondary pollution if it is not properly disposed of. It will cause serious harm to soil and water bodies, resulting in a long time for natural soil purification, affecting the growth of crops and threatening the safety of the human food chain. At the same time, the odorous gas emitted by the sludge pollutes the atmospheric environment and increases greenhouse gas emissions. The problem of river sludge pollution is serious, and it is urgent to pay attention to and do a good job in sludge treatment.

The Desen mud treatment system adopts advanced and unique scrubbing and grading treatment technology to achieve efficient treatment of ditch residual mud, river sludge, shield mud, etc.

First, after the mud enters the system, it will first be processed by the first-level soil hydraulic screen to grade and screen out the solid materials larger than 2mm in the initial material. The slurry with a size less than 2mm will enter the mud leaching module, and specific reagents will be added at this stage to make the mud and the reagent fully react.

The reacted mud is pumped into the high-efficiency immersion classification module, and then into the secondary selection module, so as to achieve efficient classification of 0.15-2mm fine sand materials and minimize the solid content of the mud filter press.

During the entire screening and grading process, an independent high-pressure water spray system is also attached to ensure that the graded aggregates are clean and pollution-free.

The slurry treated by the secondary selection module will be directly pumped into the high-efficiency concentration tank for concentration treatment. At this time, a flocculant will be added to accelerate the flocculation and grading of the mud.

After the mud is flocculated and concentrated in the concentration tank, the returned supernatant directly enters the water treatment system, and the concentrated mud at the bottom enters the mud buffer tank. The concentrated slurry is then pumped into the plate and frame filter press through the plate and frame feed pump for the final separation of mud and water.

Through this series of rigorous and efficient treatment processes, the Desen mud treatment system achieves efficient separation of aggregates, fine sand, and organic impurities, meeting the needs of reducing, harmless, and resource-based treatment of various types of mud.

Through the effective separation and treatment of pollutants, the Desen mud treatment system significantly reduces the emission of pollutants to soil, water bodies, and the atmosphere, and reduces damage to the ecological environment. In the treatment of river sludge, secondary pollution of pollutants such as organic matter and heavy metals is avoided, protecting the balance and stability of the ecosystem. The Desen mud treatment system is expected to continue to lead the industry development in the future and play a greater role in solving sludge treatment problems and protecting the ecological environment.
