摘  要：本文对规模为800 m3/d，进水COD浓度为≤16 000 mg/L，NH4+-N浓度为≤300 mg/L，SS浓度为≤760 mg/L，BOD5浓度为≤9000 mg/L倍，pH为5.5-9的高蛋白质含量废水废水进行处理工程的设计。针对该项目污水有机物浓度高，COD浓度高的特点，本设计主要采用“中和/混凝沉淀”的组合工艺处理废水，出水COD浓度为300 mg/L，NH4+-N浓度为50 mg/L，SS浓度为200 mg/L，BOD5浓度为60 mg/L倍，pH为6-9，满足要求。本设计根据含蛋白质浓度较高的废水的特性，初步设计了一个处理方案，该方案具有去除率高，污水处理成本低，运行维护简单等特点。

Abstract：Abstract: In the present thesis, we make a project designing for the treatment of highly concentrated protein wastewater, the inflow of which is 800 m3 per day, and the concentration of COD, NH4+-N, SS, BOD5 and pH from inflow is ≤16 000 mg/L, ≤300 mg/L, ≤760 mg/L, ≤9000 mg/L and 5.5-9, respectively. Since the wastewater of the project is of high organic matter concentration, and high COD concentration, combination of neutralization and coagulation sedimentation was adopted, so that the concentration of COD, NH4+-N, SS, BOD5 and pH from outflow is 300 mg/L, 50 mg/L, 200 mg/L, 60 mg/L and 6-9, respectively. Combining with the characteristics of highly concentrated protein wastewater, a project designing with good treatment effect, low operating costs, and simple to manage and maintain was designed.
