The invention relates to the technical field of
sewage treatment, in particular to a
sewage treatment artificial
wetland system which has a simple structure and high
pollutant removal efficiency. The
system comprises an underflow water distribution belt, a shallow ground surface underflow artificial
wetland and a first-stage pretreatment device, wherein a
filter material is filled in the underflow water distribution belt; at least one part of the shallow ground surface underflow artificial
wetland is covered by the underflow water distribution belt; the shallow ground surface underflow artificial wetland is a
plant planting soil layer and is inclined downwards along a
water flow direction; and the extension direction of the underflow water distribution belt is vertical to the
water flow direction of the shallow ground surface underflow artificial wetland. By the
sewage treatment artificial wetland
system, sewage can be pretreated and precisely treated; and on the premise of small floor area, low construction input, low maintenance cost, high
greening land utilization rates, high rain water closure rates and low
energy consumption, the system can be widely applied to
zero emission treatment of source sewage in an ecological cycle mode in mountain and plain regions, and the highest quality of
treated water can reach a first (A)-level standard.
