摘    要:以吉林省四平市郊区的两级潜流人工湿地生活污水处理系统为例,考察了隔离保温、特殊活性人工介质等加强化措施后的两级湿地系统在东北高寒地区运行的适应性及其效能与特征,分析了潜流人工湿地的两级组合工艺在污染物去除方面的优势.结果表明,通过特殊活性人工介质的选用和一定的隔离保温措施,两级潜流人工湿地系统能在高寒地区高效运行,其对COD、BOD5、SS、NH+4-N、TP具有稳定的去除效果,整个运行期间,出水COD、BOD5和SS平均浓度分别为16 .01、4 .27和4 .01 mg·L-1,并且可以使出水NH+4-N和TP浓度分别在9 .72和0 .45 mg·L-1以下,均达到中水水质标准;潜流人工湿地的两级组合系统,可以弥补单级人工湿地NH+4-N去除效率不高的缺点,提高污染物的去除效率.

关 键 词:两级潜流人工湿地  生物降解  污水处理  去除效果

Abstract:Base on the two stage subsurface constructed wetland system running at the suburb of Siping city in Jilin province, the applicability and characteristics of the two stage system which had especial active media and measurements of isolation for temperature protection were studied and the advantages of the two stage system in the pollution removal were analyzed. The results showed that, the choice of especial active media and the measurements of isolation for temperature protection of the system made the two stage subsurface constructed wetland run efficiently in cold area and the system had very stable effects of the COD, BOD5, SS, NH+4-N and TP removal. In the whole process, the concentration of COD, BOD5 and SS in the outflow was about 16 .01, 4 .27 and 4 .01 mg/L respectively and the concentration of NH+4-N and TP in the outflow was below 9 .72 and 0 .45 mg/L respectively. The subsurface wetland with two stages can overcome the disadvantage of the single system and improve the pollution removal efficiency.
Keywords:two stage subsurface constructed wetland  biodegradation  wastewater treatment  removal efficiency
