Described first gravel bed and water spraying pipe height are basic identical, and most of sewage is distributed in first gravel bed, and sewage horizontal plug-flow in wet land system combines with the vertical current motion, and each layer gravel filling layer of flowing through significantly improves the purification efficiency in the wet land system;
Water gathering system comprises header (identical with the water spraying pipe structure) and braiding channel, and the water shoot of the external adjustment height of header will be discharged by braiding channel behind the sewage collecting after handling.
The combined-flow structure that the utility model has adopted horizontal drowned flow to combine with vertical current has adopted the multilayer gravel filling of different-grain diameter, and has distributed rationally, and the superiors are the bigger gravel filling of particle diameter, assurance system water distribution uniformity in vertical direction.Main treatment facility is positioned at underground, can guarantee the winter operation of system.System's effluent quality reaches the water quality standard of reclaimed water reuse in landscape water body.
The utlity model has following beneficial effect:
1. the utility model wetland is handled and is adopted subsurface flow artificial wetland system, wherein undercurrent type wetland is the combined-flow water distribution manner that horizontal flow combines with vertical current, wastewater purification efficiency can significantly improve (effluent quality to pollutent indexs such as COD, BOD, ammonia nitrogen in the sewage reaches the water quality requirement of reclaimed water reuse in face of land landscape water), and the operation all the year round of the system of assurance.
2. adopted the multilayer gravel filling of different-grain diameter, and distributed rationally, the superiors are the bigger gravel filling of particle diameter, assurance system water distribution uniformity in vertical direction.Main treatment facility is positioned at underground, can guarantee the operation all the year round of system simultaneously at the processing efficiency that improves sewage.
3. floor space is little, handles 1m
3/ d sewage only need take up an area of 2～4m
2
4. adopt the utility model artificial swamp sewage ecological treatment system and urban ecology landscape construction can be realized organically combining, and be specially adapted to the northern area of China.
