In July 2020, Nanjing, Jiangsu purchased a sludge fermentation tank

Introduction to sludge fermentation tank:

Raw materials for sludge fermentation tank: As a solid waste, sludge has become a leading source of solid waste pollution.

. The main disposal methods for traditional sludge include landfill, incineration, discharge to the sea, and agriculture. However, traditional treatment methods also have some drawbacks, such as inability to resource utilize sludge and inability to meet the current technical requirements for sludge treatment. Therefore, the research and development of resource utilization for sludge treatment is of great practical significance. The treatment and disposal of sludge should be comprehensively considered from various aspects such as environmental pollution, health, and economic benefits. New technologies for sludge treatment with energy recovery and utilization will play a role in sludge treatment and disposal. The newly developed sludge fermentation tank by Wanfeng Environmental Protection Machinery can transform the troublesome domestic sludge of environmental protection departments and sewage treatment plants into organic fertilizer after treatment. It can not only reduce urban pollution and achieve waste recycling, but also fertilize soil fertility and improve the quality of agricultural products when applied to farmland

The sludge fermentation tank treatment process includes four processes: loading, high-temperature fermentation and maturation, discharging, and stable stacking.

Loading: Use a shovel truck to add the material to the hopper, and automatically load it into the fermentation tank with just one click.

High temperature fermentation and maturation: The sludge fermentation tank has a vortex air pump that delivers oxygen through the aeration holes on the stirring shaft. At the same time, the stirring shaft is stirred and gradually heats up to 50-65 degrees Celsius under the action of aerobic bacterial agents. After more than 7 days of high-temperature fermentation and maturation. Effectively kill insect eggs, pathogens, and weed seeds to achieve harmless and reduced treatment standards

Material discharge: The materials in the fermentation chamber fall layer by layer under the action of the main spindle and gravity. After fermentation is completed, the finished materials are discharged from the discharge port.

Composition of sludge fermentation tank equipment: The sludge fermentation tank equipment mainly consists of a fermentation chamber, a feeding lifting system, a high-pressure air supply system, a spindle transmission system, a hydraulic power system, an automatic discharge system, a deodorization system, and an automatic control system.
