Abstract
The invention discloses a vertical mixed flow type constructed wetland structure which comprises a pool body of which the cross section is rectangular, a water inlet pipe arranged at one end of the pool body, and a drainage pipe arranged at the other end of the pool body, wherein multiple lower brick masonry walls which are perpendicular to the bottom of the pool body and are in watertight arrangement with the bottom are arranged in the pool body; multiple suspended brick masonry walls of which the bottoms are suspended are arranged among the various lower brick masonry walls at intervals; and the height of the top of each lower brick masonry wall is smaller than the height of each suspended brick masonry wall and the pool body. According to the vertical mixed flow type constructed wetland structure, the lower brick masonry walls and the suspended brick masonry walls are arranged in the pool body so as to block the water flow, so that the retention time of the water flow in the pool body is prolonged, the time of absorbing sewage by plants microbes in the pool body is prolonged, and the aim of improving the denitrification and phosphorous removal efficiency is further achieved by virtue of a simple pool body structure. The vertical mixed flow type constructed wetland structure disclosed by the invention is applied to the field of constructed wetland structures.
Description
Technical field
The present invention relates to the body structure field, pond of artificial swamp, particularly relate to a kind of artificial swamp structure of vertical mixing streaming.
Background technology
At present, vertical current constructed wetland is widely used in process town domestic sewage and part industrial sewage.This kind wetland refers to sewage, and after pre-treatment, intermittent water distribution is to filter bed surface, and then downward longitudinal flow by gravity, the biochemical reaction of the physical filtering of binding matrix and plant and microorganism effectively processes all kinds of sewage.
Traditional vertical current constructed wetland is the single flow direction, be divided into upflowing and downflow system, usual vertical current constructed wetland is made by grouted brick, general height is 1.0-1.5m, sewage is by the downward longitudinal flow by gravity in filter bed surface, distance face, pond 5-10cm generally laid by water distributor, and water pipe is drilled with aperture and is uniformly distributed.In addition, the elevation of water surface of pond body is determined by the height of water outlet, generally arranges matrix top layer 5-10 cm.
But, the hydraulic detention time of traditional vertical current constructed wetland is short, the time that biochemical reaction needs is long, fail complete reaction, sewage flows away rapidly, thus wetland only plays the adsorption of physics, if extend hydraulic detention time, need the floor space increasing pond body, violate artificial swamp and take up an area little principle.Prove in practice, adopt the removal effect of single vertical current constructed wetland to total nitrogen in sewage and total phosphorus poor, clearance, on average 40% ~ 50%, if add other techniques to carry out auxiliary treatment, will strengthen engineering cost, and effect may not reach desirable.
