Bean products wastewater treatment project
Release time:
2024-06-25
Sichuan Food Co., Ltd. is a large-scale agricultural product deep processing base integrating food research and development, production and sales. Its main products include soy milk powder and oatmeal. The production wastewater mainly comes from the soybean milk powder production process of soaking bean hot bean wastewater, syrup workshop generated cleaning wastewater, etc., its characteristics are organic matter (protein, starch, sugar) content is high, easy to corrupt, but not harmful substances, easy to degrade, etc., the wastewater is weakly acidic. The UASB reactor has the characteristics of more biomass in the sludge bed, high volume load, high removal rate and stable water quality.

Effect after treatment
THE EFFECT AFTER TREATMENT
The effluent quality of the sewage treatment system designed for the bean products processing enterprise is good, the main water quality index can reach the discharge standard, which can well adapt to the unstable water quality of the influent, and the effluent of the system can reach the first-class standard of comprehensive sewage discharge, which effectively solves the reality of high COD in this kind of wastewater. According to the actual requirements and design process, UASB two-stage contact oxidation coagulation sedimentation treatment process is used to improve water quality and meet the requirements of effluent standards. The well ensures the long-term stable operation of the sewage treatment system.
