Fully Automatic Intelligent Sludge Ingredient Mixing Production Line

Fully Automatic Intelligent Sludge Ingredient Mixing Production Line

The fully automated intelligent sludge batching and mixing production line is a modern, eco-friendly equipment that integrates mechanical automation, sensor technology, IoT, and AI algorithms. It is primarily designed for the precise, efficient, and uniform blending of dewatered sludge with other auxiliary materials—such as straw, wood chips, return materials, microbial strains, and conditioning agents—providing a crucial pre-treatment step for subsequent sludge resource utilization processes, including aerobic fermentation/composting, incineration, brick-making, landfilling, and more.

High-temperature aerobic fermentation tank for livestock and poultry manure

High-temperature aerobic fermentation tank for livestock and poultry manure

The intelligent multi-layer aerobic fermentation tank for sludge—also known as the intelligent three-dimensional aerobic fermentation chamber or tower-type fermentation reactor—is a modern, high-efficiency sludge treatment device that integrates mechanical automation, IoT sensing technology, and microbial fermentation processes. It represents an advanced upgrade to traditional composting techniques, designed to safely, efficiently, and environmentally transform municipal sludge, organic waste, and other materials into stable humus (a raw material for organic fertilizers), thereby enabling the resourceful utilization of waste.

Ultra-High-Pressure Sludge Belt Dewatering Machine

Ultra-High-Pressure Sludge Belt Dewatering Machine

The Ultra-High-Pressure Sludge Belt Dewaterer is a revolutionary upgrade to traditional belt dewaterers, delivering significantly enhanced sludge dewatering and treatment efficiency by markedly increasing pressing force and optimizing its structural design. Its defining feature lies in its "ultra-high-pressure" capability—typically, the pressure in the final squeezing zone can reach 20–30 kN/cm (approximately 200–300 kg/cm) or even higher, far surpassing the 6–15 kN/cm commonly seen in conventional belt machines.

High-Temperature Aerobic Fermentation Technology for Sludge

The high-temperature aerobic fermentation process for sludge involves mixing deeply dewatered sludge—now containing 40–50% moisture—with our specially activated, thermophilic microorganisms, and then transferring the mixture into an intelligent, high-temperature aerobic fermentation tank for controlled aeration. During fermentation, the temperature rapidly rises to over 70°C, effectively eliminating various microorganisms, pathogens, and weed seeds while simultaneously breaking down most of the organic matter in the sludge. This process ensures the sludge is safely treated, significantly reduced in volume, and transformed into a resource that can be reused. After fermentation, the final product achieves a moisture content of below 40%, exhibiting excellent maturation, with loose, crumbly particles ideal for landscaping, greenery projects, and land reclamation applications.

The waste heat recovery system utilizes the residual heat from fermentation exhaust gases to preheat fresh air entering the high-temperature fermentation chamber, effectively harnessing the heat generated during the fermentation process. This prevents significant energy waste, enabling resource recycling while also maintaining the high-temperature environment required in the fermentation chamber, thereby enhancing the fermentation rate.
A layered, intelligent high-temperature aerobic fermentation tank is employed, with the tank walls featuring a double-layer insulation technology that significantly boosts the fermentation rate, reducing the fermentation time to just 1–2 days (compared to the traditional 10–15-day cycle for aerobic sludge fermentation). This innovative approach also effectively addresses challenges such as low winter temperatures, slow initial warming, and extended fermentation periods.
