Desen Integrated River Sludge Treatment Equipment

The siltation of river channels is a persistent problem in urban water environment management, which not only affects flood safety but also becomes a potential source of pollution due to the presence of heavy metals, organic matter, and other pollutants. DeSen Environmental Research and DevelopmentDesen Integrated River Sludge Treatment EquipmentWith "convenient mobility, efficient processing, and resource recycling" as the core, it provides an integrated solution for river dredging.

This device adopts a modular integrated design, consisting of four modules: sludge conveying, dewatering and drying, sludge water separation, and resource recovery. It can be quickly transported to the riverbank by truck without the need for large-scale infrastructure construction, and installation and commissioning only take 24 hours. During operation, the suction dredger transports the sludge to the equipment, where impurities such as tree branches and stones are first removed through vibration screening. Then, it enters the plate and frame pressure filtration module for water and sludge separation, reducing the moisture content of the sludge from over 95% to below 30% and reducing its volume to 1/5 of the original, greatly reducing subsequent transportation and disposal costs.

More importantly, in the resource recovery process, the dehydrated mud cake can be used as landscaping soil or roadbed filling material if its heavy metal content meets the standard after testing; The separated clean water is purified by sedimentation tank and membrane filtration system, reducing the suspended solids content to below 10mg/L. It is directly reused for river water replenishment or equipment cleaning, with a water recycling utilization rate of over 90%. In a black and odorous river treatment project in a city in Jiangsu Province, this equipment can process 200 tons of silt in a single day and complete 5 kilometers of river dredging within 3 months. The treated mud cake is used to shape the surrounding park terrain, achieving a three-level leap of "silt reduction harmless resource utilization".

Desen Integrated River Sludge Treatment EquipmentThe advantage lies in the combination of "dredging" and "resource recycling", which not only solves the problem of pollution caused by silt accumulation, but also provides recycled materials for urban construction, shifting the long-term mode of river treatment from "dredging as the end point" to "recycling and reuse".
