Treatment of Slaughter Wastewater by Regulation Pool/Hydrolysis Acidification/Contact Oxidation

Abstract:

Used slaughter wastewater treatment engineering of some food industry group in Liaoning Anshan as example. Introduced process characteristics, design parameters, treatment effect and operation cost of treating slaughter wastewater by regulation pool/ hydrolysis acidification/ contact oxidation process. The project of water treatment capacity is 8000m3/d, the average concentration of COD、BOD、NH3-N and oil respectively was 2000mg/L、1200 mg/L、120mg/L and 200 mg/L respectively. The treated water concentration can reach 44mg/L、8 mg/L、6 mg/L and 5 mg/L respectively. Good treatment effects can be achieved by regulation pool/ hydrolysis acidification/ contact oxidation process, the effluent can meet requirement of Comprehensive Wastewater Discharge Standard (DB21/1627-2008), and the process has the advantages of low operating cost, treatment costs of each ton water is 1.78 Yuan/t.
