Construction mode


The overall treatment process fully considers the composition and characteristics of kitchen waste materials, and adopts the collaborative treatment process of "Pretreatment and Full material pulping and Three-phase separation and solid phase aerobic fermentation/liquid phase anaerobic fermentation", including mechanical reception, storage and transportation, crushing and pulping technology, wet and hot oil-water separation and treatment technology, anaerobic digestion, aerobic fermentation and other resource-based treatment technologies, to make a breakthrough in solving the problems of low resource utilization rate and limited reduction in the industry. The waste gas in the production process shall be discharged in an organized way and comprehensively deodorized. It shall be discharged after reaching the standard to reduce the secondary pollution to the environment.


A kitchen waste resource disposal plant using solid aerobic fermentation and liquid anaerobic fermentation to achieve energy self-sufficiency

Production facilities include kitchen waste comprehensive treatment workshop, anaerobic digestion system, sewage treatment system, process waste gas treatment, and supporting production and living auxiliary facilities to realize harmless treatment and resource utilization of kitchen waste. Specific process description: Food waste → Pretreatment → Crushing and pulping → Damp heat and oil-water separation system, Solid phase aerobic fermentation and liquid phase anaerobic fermentation → auxiliary system. The whole process is closed and automatic, so as to scientifically and rationally realize the harmless, reduced and resourceful treatment of kitchen waste.

With the innovative idea of "aerobic+anaerobic" collaborative treatment of kitchen waste, the organic matter is divided and used in different grades. The conversion rate of organic matter is more than 75%, and the reduction rate and recycling rate of solid waste are more than 80%. It is a good recycling solution in the industry at present.

Compared with other processes, this technology has the following significant advantages:

1. Match with the collection and transportation rhythm, and the waste will be dispose immediately when it arrive.

The parallel connection mode of large oxygen control biochemical treatment equipment is adopted, and the single treatment unit is matched with the collection and transportation vehicle, which means that it can be immediately arrived, immediately disposed and cleared, without stagnation in the unloading area, and the environment is excellent.

2. Classification of organic matter to achieve full utilization

The organic matter is classified and used in different grades. The relatively active and water-soluble organic matter is anaerobic fermented to form biogas, which is used as energy for aerobic fermentation of inert organic matter to maximize the value of resources and increase the project income.

3. High reduction level, supporting waste classification

Benefited from refuse classification, the residue rate of the project is stable between 13-18%, and the reduction rate is about 85%, both at a high level in China, providing necessary terminal disposal support for the "new fashion" of refuse classification.

4. Serve soil improvement and promote carbon reduction and fixation

The resource-based products have been applied to soil improvement and construction of high standard farmland, playing the role of fertilizer and water conservation, quality improvement and efficiency enhancement, promoting agricultural supply side reform and poverty alleviation, and have dual effects of emission reduction and carbon sequestration.

5. Practice promotes standards and standardizes industry development

Taking the project resource product standard as the indicator, the agricultural department was assisted to issue the kitchen waste agricultural product standard, which changed the "theory of the bloodline" of kitchen waste products and standardized them into the correct channel of the standard theory.


By the end of 2022, the kitchen waste treatment scale will reach 3310 tons/day, covering major cities in China, serving about 40 million people. The project investment and operation scale will rank fifth in the country and first in private enterprises.
