NOVELTY - A sewage treatment method of integrated constructed wetland comprises firstly treating sewage by pre-treating pool, and introducing into constructed wetland pool with vertical flow and constructed wetland pool with horizontal undercurrent; and secondarily treating sewage by refluxing in water collecting pool (12) after being treated by constructed wetland pool (30) with horizontal undercurrent, where water collecting pool is provided with sewage pump (13) which is communicated with water distribution pipe (6) arranged on constructed wetland pool (29) with vertical flow by a valve.    USE - Sewage treatment method of integrated constructed wetland.    ADVANTAGE - The method exhibits high sewage treatment efficiency, has high sewage purifying efficiency in unit area, and provides good quality of discharged water.    DETAILED DESCRIPTION - Sewage treatment method of integrated constructed wetland comprises firstly treating sewage by pre-treating pool, and introducing into constructed wetland pool with vertical flow and constructed wetland pool with horizontal undercurrent; and secondarily treating sewage by refluxing in water collecting pool (12) after being treated by constructed wetland pool (30) with horizontal undercurrent, where water collecting pool is provided with sewage pump (13) which is communicated with water distribution pipe (6) arranged on constructed wetland pool (29) with vertical flow by a valve. The water collecting pool is communicated with water outlet of constructed wetland pool with horizontal undercurrent by pipeline. The water after being treated secondarily is divided into 2 branches, water of one branch is recycled, and water of other branch is flowed into feeding pool of water purifying agent for tail water for treating in ecological recovering manner. The water is discharged after reaching standard, feeding pool of water purifying agent for tail water is provided with ecological environmental friendly composite water treating agent.
