Against the backdrop of rapid urbanization, the ditch sludge accumulated in the drainage network has become a chronic problem in environmental governance. The composition of these sludges is staggeringly complex: gravel and construction waste account for most of it, rotten organic matter carries the pungent smell of hydrogen sulfide, and heavy metals and microplastics are like invisible killers, quietly infiltrating into the soil and water. What's more difficult is that the physical properties of sludge make its treatment cost high - the initial moisture content is as high as 95%, and even after natural sedimentation, it remains above 60%, and the energy consumption for transportation and disposal far exceeds that of ordinary garbage.
Faced with the problem of ditch sludge treatment, the modular ditch sludge treatment equipment developed by Desen Environment is like a precise "scalpel", dissecting the complex mixture layer by layer and transforming it by category. The core logic of this equipment lies in "grading and disassembling, making the best use of everything":
The first step is to select the universe with intelligent classification
Through the combination of hydraulic washing and cyclone screening, the gravel, organic matter, heavy metals and microplastics in the sludge are accurately separated. After cleaning, the purity of construction aggregates with a particle size greater than 5 mm reaches 98%, and they can be directly used in municipal projects; the fiber-rich organic matter is dehydrated and dried, and the calorific value is increased to 2000 kcal/kg, making it the preferred alternative fuel for cement plants; heavy metal pollutants are locked through magnetic separation and chemical stabilization technology, and the leaching toxicity is reduced to a safe threshold; even the most difficult to handle microplastics are converted into carbon-based materials during high-temperature pyrolysis, achieving more than 90% resource conversion.
The second step is data-driven efficiency improvement
The "smart brain" of modular sludge treatment equipment is even more commendable. The 5G Internet of Things system monitors the fluctuation of sludge composition in real time, automatically adjusts the sorting intensity and dehydration time, and improves the processing efficiency by 30%; the AR remote operation and maintenance system "brings" experts to the site, shortening the fault repair time to 2 hours; the processing data is directly connected to the government supervision platform, and the flow and transformation results of each ton of sludge are clearly traceable. In a pilot project in Foshan, this system helped the company reduce its comprehensive energy consumption by 40%, and the resource benefits exceeded 300 yuan/ton.
The history of ditch sludge treatment is a mirror of the evolution of urban civilization. From extensive landfill to precise resource utilization, from passive pollution control to active value creation, modular technology has not only solved environmental problems, but also reshaped the relationship between humans and waste. When sand and gravel return to the construction site, organic matter is converted into energy, and heavy metals stop wandering, the "blood vessels" of the city are being reborn in the baptism of science and technology.
