Abstract
This paper analyzed the related methodsto removethe biological indicatorEscherichia coli K12 (E. coli K12) in the constructed wetland system (CWs), which included filtration and absorption of filling, effect of the plant root system and microorganism phagocytosis and so on. It indicated that E. coli K12 was mainly removed through filtration and absorption of filling, about 80% was removed by this process. Plants and microorganisms alsocontributed to the removal of E. coli K12. The removal load of E. coli K12 increased with the addition ofpollution load. When hydraulic retention time (HRT) was 4d, there was a better linear relation (R2 = 0.9998) between the removal load of E. coli K12 and pollution load. Meanwhile, it had a close relation between inactivation ratio of E. coli K12 and hydraulic load, the lower hydraulic load was, the higher inactivation ratio was.
