摘要
采用生物接触氧化/温室结构潜流人工湿地工艺处理牡丹江市某农场生活污水,对该工程冬季在高寒地区的运行效果进行了考察,重点分析了其对COD、NH4+-N和TP的去除效果。结果表明,组合工艺对冬季生活污水中COD、NH4+-N、TP等有稳定的去除效果,出水COD、NH4+-N和TP的平均浓度分别为24.49、10.79和2.31 mg/L。潜流人工湿地在使用覆盖物进行隔离保温后可以正常运行,该组合工艺的应用可以弥补冬季单级人工湿地去除率不高的缺点,提高对污染物的去除率。
The combined process of biological contact oxidation and greenhouse structure subsurface-flow constructed wetland was used to treat domestic sewage from a farm of Mudanjiang City. The operation efficiency of the combined process in cold area in winter was investigated. The removal efficiencies of COD, NH4＋ - N and TP were analyzed. The results show that the combined process has stable removal effieiencies of COD, NH4 - N and TP in winter. The average concentrations of COD, NH4 - N and TP in the effluent are 24.49 mg/L, 10.79 mg/L and 2.31 mg/L respectively. After being insulated with covers, the subsurface-flow constructed wetland can normally operate. The combined process can overcome the disadvantage of the single subsurface wetland and improve the pollutant removal efficiency in winter.
