Food Kitchen Waste Utilization and Harmless Biogas Plant


Project Overview

The whole project treatment capacity is 150T/D catering waste, 150T/D kitchen waste and 20T/D waste oil. This treatment system is constructed in the original pre-treatment workshop, along with the construction of a cogeneration workshop, a new 5000m³ anaerobic fermentation tank, a new 200m³/D wastewater treatment system and an odor treatment system.

 

Treatment process

● This project adopts pretreatment+anaerobic fermentation+biogas power generation to treat catering waste, kitchen waste and waste oil.  

● The pre-treatment of catering waste adopts material reception+large material sorting+crushing and pulping+sand and impurities removal+oil-water separation.  

● The pre-treatment of kitchen waste adopts material receiving+tearing and squeezing. 

● The pre-treatment of waste oil adopts material reception+impurity removal+steaming+three-phase separation). 

● The pulp generated from the pre-treatment of catering waste, kitchen waste, and waste oil is mixed and anaerobic digested together. 

● The anaerobic generated biogas is first supplied to biogas boilers after purification, and the remaining biogas is used for power generation.

 

Treatment Capacity

12000Nm³/D biogas and 500KW.H biogas eletric power supplies.
