摘要: 运用自行设计的人工湿地模拟装置处理人工污水,研究了污水在系统中的净化动态和最佳停留时间,并初步探讨了pH、Eh和气温对净化效率的影响。试验结果表明,有树系统5天内的净化率分别为:BOD594.8%,总氮93.0%,总磷95.0%,氨氮99.5%。当Pb、Cd浓度分别在2500mg/L和250mg/L以内时,系统对Pb、Cd的净化率为99.9%以上,并可在3小时内基本完成。即使在“土壤”含Pb量达2.86g/kg和含Cd量达0.29g/kg的情况下,系统对Pb、Cd的净化率仍可达96.2—98.5%。

Abstract: Using simulated artificial wetlands for wastewater treatment, the purification dynamic and optimum detention time in the system were studied, and the effects of pH, Eh and temperature on purification were discussed. The mean removal efficiencies in5 days were BOD5 94.8%, TN 93.0%, TP95.0% and NH3-N 99.5%. When the Pb and Cd concentrations were under 2500mg/Land 250mg/Lrespectively, the removal efficiencies of Pb and Cd were more than99.9%, and the process was basically completed in3 hours. Even if the Pb content is 2.86g/kg and Cd 0.29g/kg in substrate, the removal efficiencies of Pb and Cd were still 96.2—98.5%.
