摘要：本文对西南某大型竹材制浆废水处理工程进行了研究。该废水工程采用常规的"预处理-生化-气浮"三级处理工艺,竹材制浆废水的污染物特征(COD、色度、TP和NH3-N)波动性比较大,竹浆综合废水的COD、色度和TP平均值为1 256 mg/L、315倍和5.98 mg/L,曝气池中氨氮平均值为3.73 mg/L。该竹材制浆废水工程具有良好的抗冲击和缓冲性能,COD、色度、TP和NH3-N去除率平均值为94.35%、94.60%、97.83%和63.81%,出水均满足国家排放标准。此外,对竹材原料质量管理亟待加强,确保废水水质稳定;同时面对日益严峻的环保形势,亟需开发高效氧化混凝剂,保证废水稳定达标排放,减低竹浆废水工程运行成本。
In this paper,a large-scale bamboo pulping wastewater treatment project located in the southwest region of China is studied,in which a common three-stage treatment process including'pretreatment-biochemical-floatation'is adopted.The characteristics of pollutants(COD,color,TP and NH3-N)in bamboo pulping wastewater often fluctuate greatly,with average values of COD,chromaticity and TP in influent wastewater being 1,256 mg·L-1,315 times and 5.98 mg·L-1,respectively.The average concentration of nitrogen(in the form of ammonia)in the aeration tank is 3.73 mg·L-1.This bamboo pulping wastewater treatment system has very good impact resistance and buffering performance.Through treatment by this system,the average removal rates of COD,color,TP and N(NH3)in bamboo pulping wastewater can reach 94.35%,94.60%,97.83%and 63.81%,respectively,satisfying China’s national discharge standards.Furthermore,the quality management of bamboo raw materials shall be strengthened in China so that the wastewater composition remains stable.High-efficiency oxidizing coagulant shall also be developed to reduce the operating cost of bamboo pulp wastewater treatment and ensure the stable and qualified discharge of wastewater.
