Embodiment 1

[0028] The four-stage vertical flow compound constructed wetland treatment system of the present invention consists of four parts: "one-stage vertical downflow wetland unit + two-stage vertical upflow wetland unit + three-stage vertical upflow wetland unit + four-stage vertical downflow wetland unit".

[0029] The river sewage is lifted by the pump to the first-level vertical downflow wetland unit, and the sewage is evenly distributed in the first-level vertical downflow artificial wetland through the "king"-shaped water distribution pipe on the top of the first-level vertical downflow artificial wetland, and then passed through the treatment medium The percolation reaches the bottom, and the sewage after the first-level vertical downflow treatment is connected to the bottom water distribution pipe of the second-level vertical upflow constructed wetland unit by the bottom water collection pipe. Utilizing the adsorption properties of the matrix and atmospheric pressure, the sewa...

Embodiment 2

[0041] The composite vertical downflow constructed wetland system consists of two vertical downflow wetland units connected in series, a bed body and a water collection pipe. The bed wall of the bed body is a brick structure with cement plaster, and the bottom is a concrete structure. The length × width × height of the first-stage vertical downflow constructed wetland of the composite vertical downflow constructed wetland treatment system is 8m×8m×1.6m, and the length×width×height of the second-stage vertical downflow artificial wetland is 8m× 8m x 1.4m. The drop between the first and second wetland units is 20cm.

[0042] The sewage from the Dongguan Canal is pumped up into the "king"-shaped water distribution pipe on the top of the first-stage wetland of the composite vertical downflow artificial wetland, and the sewage is evenly distributed in the first-stage vertical downflow artificial wetland, and then reaches the bottom through the percolation of the treatment medium ,...

Abstract

The invention discloses a method for processing sewage of a multilevel vertical-current compound manual wetting ground system and a processing system thereof. The method comprises the steps of addinga vertical downstream and a vertical upstream wetting ground processes based on the compound vertical downstream-upstream manual wetting ground process, and treating the sewage by a four-level serialvertical current manual wetting ground process. The vertical-current manual wetting ground comprises a bed, a water distributing pipe and a treating medium. The sewage is uniformly distributed into the wetting ground by the water distributing pipe through a first-level vertical downstream manual wetting ground and the processed sewage is processed in a fourth-level vertical downstream manual wetting ground by orderly passing through a second and a third-level vertical upstream manual wetting ground units. The invention has low processing cost, occupies small area and can obviously remove nitrogen and phosphor.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a method for treating sewage in a multi-stage vertical flow compound artificial wetland and a treatment system thereof. Background technique [0002] Vertical flow constructed wetlands can be divided into three types: upflow, downflow and tidal flow, and their hydraulic conditions combine the characteristics of surface flow wetlands and horizontal subsurface flow wetlands. The downflow is that sewage flows longitudinally from the surface of the wetland to the bottom of the packing bed, concentrates in the collection pipe and is discharged; the direction of the upflow water flow is opposite to the downflow, because the bed is in an unsaturated state, and oxygen enters the wetland through atmospheric diffusion and plant transmission. This kind of wetland has strong nitrification ability, is suitable for treating sewage with high ammonia nitrogen content, and has a high r...
