With the acceleration of urbanization, the maintenance of urban underground drainage pipelines and the treatment of trench sludge have become important tasks in urban management. Trench sludge contains a large amount of sediment, organic matter, and various pollutants. Improper treatment not only clogs drainage pipelines and affects the normal operation of the urban drainage system but also pollutes the surrounding environment and threatens urban ecological security. As a professional environmental protection equipment, the Desen Washing plant has demonstrated strong capabilities in urban trench sludge treatment, emerging as a new force in safeguarding the urban environment.  

Targeting the complex composition and characteristics of trench sludge, Desen has developed a comprehensive and efficient treatment process for its washing plant. When trench sludge is collected and transported to the washing plant, it first enters the pretreatment stage: high-efficiency screening equipment separates large impurities such as bricks, stones, and branches from the sludge, preventing damage to subsequent treatment equipment.  

Next, the pretreated sludge enters the washing module. During the washing process, the Desen Washing plant accurately adds an appropriate amount of washing agent based on the pollution degree and composition of the sludge. Through sufficient stirring and chemical reactions, pollutants in the sludge are dissolved and separated from the sediment.  

Subsequently, advanced cyclones and dehydration equipment are used to achieve efficient solid-liquid separation: the sediment is dehydrated to form dry sludge cakes, while the washing liquid containing pollutants enters the water treatment module for deep purification. The treated dry sludge cakes can be safely landfilled or recycled for making building materials, and the purified water can be recycled or discharged up to standard—greatly reducing environmental pollution and water resource waste.  

In a drainage pipeline maintenance project in a certain city, the application of the Desen Washing plant achieved remarkable results. The city’s drainage pipelines had accumulated a large amount of trench sludge for a long time, leading to poor drainage and frequent waterlogging during the rainy season, which seriously affected residents’ lives. After the Desen Washing plant was put into use, it quickly cleaned and treated the trench sludge. After a period of continuous operation, the drainage pipelines were unblocked, the trench sludge was effectively treated, and the city’s drainage capacity and environmental quality were significantly improved. The efficient treatment capacity and environmental protection advantages of the Desen Washing plant have won high praise from the local government and residents.  

Relying on its advanced technology, reliable performance, and excellent treatment effects, the Desen Washing plant provides a scientific and effective solution for urban trench sludge treatment. It serves as an important support for urban environmental governance and contributes to building a clean, beautiful, and livable urban environment.
