Application of sludge dewatering screen in sludge treatment

July.23,2024

From the perspective of sludge treatment equipment supply, the equipment supply chain of sludge treatment can be refined and divided into tempering and wall breaking, sludge dewatering machine, conveying equipment, deodorizing equipment, digestion equipment, composting equipment, drying equipment, and incineration equipment according to demand. Among them, the technical content of dewatering machine, conveying equipment, and deodorizing equipment is relatively low, and tends to be general equipment; while the technical content of digestion equipment, composting equipment, drying equipment, and incineration equipment is relatively high, involving the company’s parameter setting for sludge treatment process, engineering experience, etc.; the highest technical barriers are still related technical equipment of tempering and wall breaking.

Harmlessness and stabilization are the basic requirements of various treatment technologies, and the method is incineration and subsequent treatment of fly ash; tempering and wall breaking are the key links to achieve breakthroughs in the requirements of reduction; in energy resource utilization, anaerobic digestion and coordinated incineration are the development direction.

The sludge treatment market is currently in its infancy, and the treatment scale of various companies in the industry is small and highly dispersed, basically at a disposal scale of less than 1,000 tons/day.

From the perspective of the upstream and downstream of the industrial chain, the upstream of sludge treatment is sewage treatment, and the downstream is the sales and utilization of products after sludge resource treatment. The sludge treatment process can be divided into several categories: environmental impact assessment design, equipment supply, engineering construction, and operation services. Listed companies are mainly concentrated in the two sectors of equipment supply and operation services.
