Gelatin wastewater is significantly different from common industrial wastewater,as its composition is more complex and the treatment difficulty is greater.Taking a gelatin production enterprise as an example,different wastewater treatment processes are compared and selected based on the design of the wastewater treatment plant's treatment scale and the quality of the inflow and outflow water.After comparison,the wastewater treatment station adopts a combination process of"primary sedimentation tank+air flotation tank+hydrolysis tank+anaerobic oxic biochemical tank+secondary sedimentation tank"to treat gelatin wastewater.After treatment with this process,the main indicators of chemical oxygen demand,biochemical oxygen demand,and ammonia nitrogen in the effluent meet the design requirements and meet the first level standards of the Comprehensive Wastewater Discharge Standard(GB 8978-1996).
