摘要
应用复合塘-湿地生态系统对草浆造纸中段废水进行强化处理,处理能力3万m3/d。最终处理单元出水的CODCr、BOD5、TSS浓度的全年平均值分别可达到105.8、102.1、39.8mg/L。系统夏季的运行效果优于冬季,但是系统设计包含了总容量270万m3的净化存储塘,可实现冬季3个月系统废水全部存储不外排,保证全年出水达到排放标准。
Advanced combined pond-wetland eco-system with treatment capacity of 30000m^3/d was applied to treat the washing and bleaching effluent from the straw pulping line and the good treatment efficiency was recognized. The annual average values of CODCr, BOD5, TSS of the effluent from the last wetland could reach 105.8, 102.1, 39.8 mg/L respectively. The system pollutants removal efficiency in summer was better than in winter. The storage pond with 27Mm^3 was adopted which could guarantee the treatment efficiency all the year around.
