Abstract
The invention relates to a composite artificial wetland denitrifying and dephosphorizing device for surface flow-vertical underflow-two level surface flow, which mainly comprises a plastic water distribution bucket, a peristaltic pump, a wetland unit (made of plastic and organic glass), a water inlet tube, a water outlet tube, a valve, stuffing filling and sampling columns and the like, wherein a water distribution device pumps distributed water into the wetland through the peristaltic pump; the outflow water is discharged into a municipal administration water drainage tube network through the water outlet tube; the wetland unit is filled with zeolite which has different grain diameters and thicknesses is used as an adsorption layer; pollutants move and transform under the action of the zeolite and microorganisms when the pollutants flow through a zeolite stuffing layer; the contents of carbon, nitrogen and phosphorus in the inflow water, the outflow water and the water of each processing unit are periodically detected; the stuffing filling and sampling columns are arranged in test grids so as to realize the layering sampling of stuffing, wherein each test grid can be provided with a plurality of sampling columns); and the absorption effect of the stuffing with different depths can be analyzed.
Description
Affiliated technical field
The present invention relates to a kind of surface current-vertical subsurface flow-two-stage surface current combined artificial wetland waste disposal plant, be used to study the removal effect of the composite constructed wetland system of filling different-grain diameter zeolite carbon, nitrogen and phosphorus.
Background technology
Artificial swamp can be divided into 2 types by sewage mobile mode difference in wetland bed: surface current artificial wetland (Surface FlowWetland; SFW) and drowned flow artificial wet land (Subsurface Flow Wetland; SSFW); Current wetland according to water (flow) direction be divided into vertical subsurface flow wetland (Vertical Flow Wetland, VFW) and horizontal drowned flow artificial wet land (Horezental Flow Wetland, HFW).With the drowned flow artificial wet land of homalographic the removal effect of pollutent is better than the surface current artificial wetland usually.Artificial swamp matrix can and provide effect such as attachment point to remove nitrogen, phosphorus in the sewage effectively through absorption for mikrobe.
Summary of the invention
The objective of the invention is: (1) makes full use of surface current-vertical subsurface flow-two-stage surface current combined artificial wetland and handles the major part removal of bed completion to oxygen consumption organic and suspended substance; (2) in artificial swamp, adopt the matrix of high nitrogen adsorptive power, to reach the clearance of higher nitrogen: its clearance situation to phosphorus is investigated in (3) when reaching the requiring of nitrogen removal efficiency.
Primary member of the present invention is filled sampling column by water dispensing apparatus, artificial swamp unit and filler and is formed.Water dispensing apparatus is made up of storage pencil, water distributing pipe, sewage preparation and storing unit, stirring rod and peristaltic pump, and former water gets into artificial swamp through peristaltic pump.Artificial swamp is by being made up of four unit, and artificial wetland effluent is discharged by water shoot, and overall draining is by bottom discharge management and control system.It is the right cylinder of glass reinforced plastic material that filler is filled sampling column; Upper opening, bottom and post jamb are beaten Φ 5mm aperture (evenly densely arranged), and sampling column is put into the test lattice before the test lattice are filled filler; Filler with test lattice filling the same terms; When the device run duration, then can extract sampling column out sampling to filler stratified sampling in the test lattice if need.Regularly collected specimens is analyzed the analysis of filling adsorption analytic properties, filler reproducing characteristic, microbiological property etc.
The beneficial effect of this practical patent of invention is; Can under static conditions, study the real-time absorption situation of zeolite to water pollutant; Characterize also can realize the stratified sampling of filler to the removal and the interdiction capability of nitrogen and phosphorus, can analyze the adsorption effect of different depths filler.
