从能量分配和压力水头分布出发,阐述了垂直流人工湿地穿孔管配水系统能量分布及压力水头分布状况.在此基础上,提出了影响垂直流人工湿地配水均匀性的2个关键影响因子-最不利2点流量关系及穿孔管布水系统内部配水间隔时间,得出了垂直流人工湿地配水系统中最不利2点的孔口出流流量关系式及垂直流人工湿地穿孔管布水系统内部配水间隔时间,为采用穿孔管配水的垂直流人工湿地提供了理论研究资料.
Energy distribution and pressure head distribution of porous pipe in the vertical-flow constructed wetland were analyzed. And then two key influencing factors most two disadvantageous points and the distributing water time that affect the uniformity in the vertical-flow constructed wetland were put forward. From pressure head analysis, discharge relationship in the distribution system of porous pipe about most two disadvantageous points (a, c) was got. Finally, the distributing water time has been set up.
