Introduction to the Multi-layer Sludge Ultra-High-Temperature Aerobic Fermentation Tank
The multi-layered sludge ultra-high-temperature aerobic fermentation tank, 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—precisely the raw material for organic fertilizers—thereby enabling the resourceful utilization of waste.
I. Core Design: Multi-layered Three-Dimensional Structure
· Top Layer (Feed Layer): After pre-treated sludge is mixed with a conditioning agent, it undergoes advanced dewatering through an ultra-high-pressure belt sludge dewatering machine and is then conveyed by a scraper conveyor to the topmost layer.
· Intermediate Fermentation Layer (Main Reaction Zone): Under the influence of gravity, the material moves downward layer by layer via tiered flip plates or a pushing mechanism. Each layer is equipped with independent aeration, mixing, and temperature/humidity monitoring systems, providing microorganisms with an optimal aerobic fermentation environment.
· Bottom layer (discharge layer): After several days of complete fermentation, the fully matured material is discharged from the lowest layer and moves on to subsequent screening and packaging processes.
II. Working Principle: Intelligent Aerobic Fermentation
At its core, it involves using aerobic microorganisms to break down organic matter, with the entire process carried out under the precise control of an intelligent system.
1. Intelligent Feeding and Mixing: The system automatically calculates and adds the appropriate amounts of conditioner and recycled matured material based on parameters such as sludge moisture content and organic matter levels, ensuring the carbon-to-nitrogen ratio of the initial mixture is optimized. C/N )、porosity and moisture content are within the optimal range.
2. Precise Environmental Control:
· Ventilation and aeration: Each layer is equipped with an air-distribution system, powered by a central unit. PLC Based on real-time monitoring of oxygen concentration and temperature data, the system intelligently adjusts the fan airflow to ensure the fermentation process remains consistently in a highly efficient aerobic state, preventing the generation of odors.
· Temperature Control: Sensors continuously monitor the temperature of each layer. The system adjusts ventilation and mixing to ensure the material undergoes heating ( >55 ℃), high temperature (continuous 55–70 The process consists of four stages—elevating the temperature to kill pathogens and weed seeds, cooling down, and completing composting—which fully meet the requirements for harmless treatment.
· Humidity Control: By monitoring humidity, the system can automatically detect the moisture level of the material and maintain the optimal humidity required for microbial activity.
3. Automatic Mixing and Conveying: Periodically or according to programmed settings, the mixing devices on each layer agitate the material, breaking up temperature stratification, replenishing oxygen, and ensuring more uniform fermentation. Once completed, the flipping plates open, allowing the material to drop onto the next layer, thus enabling continuous production.
4. Full-process monitoring and the Internet of Things IoT ): All data—including system-wide temperature, humidity, oxygen levels, pressure, and material positions—are uploaded to the central control room. Operators can access this information via computer or mobile phone. APP Remote monitoring and adjustment of process parameters enable unmanned operation and intelligent management.
III. Core Advantages and Features
Compared to traditional methods, intelligent multi-layer fermentation tanks offer overwhelming advantages:
· Small footprint: The compact, three-dimensional design significantly conserves land resources, occupying only a fraction of the space required by traditional trough fermentation. 1/5 To 1/10 。
· High efficiency and energy savings: The fermentation cycle is short, and thermal energy is fully utilized through a heat exchange system (heating the low-temperature layer with the high-temperature one). Intelligent ventilation also prevents unnecessary power consumption.
· Environmentally friendly, with no secondary pollution:
· The entire process is fully enclosed, with exhaust gases collected centrally and routed to a bio-deodorization or chemical scrubbing tower for treatment, effectively addressing the issue of uncontrolled emission of odorous gases.
· The leachate can be collected and returned to the front-end conditioning process, enabling in-plant recycling with no wastewater discharged externally.
· Stable product quality: Intelligent control ensures that fermentation conditions are always optimized, resulting in organic fertilizer raw materials that are thoroughly decomposed, stable and harmless, and uniformly high in quality.
· High degree of automation, low labor costs: The entire process—from feeding, stirring, transferring materials to discharging—is fully automated, significantly reducing reliance on manual labor and easing the physical workload.
· Unaffected by weather: The equipment is fully enclosed, enabling year-round operation. 365 The system operates continuously and reliably, unaffected by adverse weather conditions such as rain, snow, or freezing temperatures.
4. Application Areas
· Municipal wastewater treatment plant: Treats municipal sludge to achieve volume reduction, stabilization, harmlessness, and resource recovery.
· Food processing plants and breweries: Handling sludge and waste generated from high-concentration organic wastewater.
· Livestock and poultry farms: Treat livestock and poultry manure to produce organic fertilizer.
· Landscape Waste Treatment Center: Co-treatment with green waste.
V. Summary and Outlook
The intelligent multi-layer fermentation tank for sludge is a prime example of the deep integration between environmental protection technology and smart manufacturing. It has successfully transformed what was once a traditionally "dirty, chaotic, and odorous" industry into a clean, efficient, and intelligent modern production process—perfectly aligning with the current policy directions of building "zero-waste cities" and achieving the "dual carbon" goals.
