Description

A kind of compound baffling artificial swamp
Technical field
The utility model relates to sewage treatment area, is specifically related to a kind of compound baffling artificial swamp for sewage disposal.
Background technology
Artificial swamp utilizes matrix, microorganism and plant three's synergy to dispose of sewage, and can reach and purify waste water and the dual purpose that strengthens view, has simple to operately, the advantage such as safeguards and working cost is low, is a kind of cost-effective ecological reestablishment.The at present application of Artificial Wetland Techniques in sewage disposal is increasingly extensive, has broad application prospects.In actual engineering design, this three classes wetland of surface current artificial wetland, horizontal drowned flow artificial wet land and vertical current constructed wetland is the most basic type of reactor.There is more problem in actual applications in traditional artificial swamp, and is out of condition such as wetland waterpower, easily forms the dead band, and filler easily stops up, and wetland denitrification effect is undesirable, and the total nitrogen removal effect is relatively poor etc., is difficult to satisfy different pollutant removal demands.Therefore, the novel wetland that the exploitation hydraulics is good, nitric efficiency is high has larger pushing effect and more practical value for the widespread use of artificial swamp.

The purpose of this utility model is to provide a kind of compound baffling artificial swamp, to improve the defective that exists in the known technology.
For achieving the above object, the compound baffling artificial swamp that the utility model provides, wherein, a side roof part of bed body is equipped with water-distributing device, and the bottom of bed body the same side is equipped with lower water-distributing device; The opposite side of bed body is equipped with captation;
Be provided with staggered up and down Multi-level deflector plate in the bed body;
Be filled with filler in the bed body, lower floor's filler is large particle diameter gravel, and the middle level is middle particle diameter gravel, and the upper strata is the small particle size gravel.
Described compound baffling artificial swamp, wherein, the water distributor of upper water-distributing device and lower water-distributing device is H type perforated pipe.
Described compound baffling artificial swamp, wherein, upper water-distributing device and lower water-distributing device are the multiple spot water distribution.
Described compound baffling artificial swamp, wherein, captation is T-shaped perforated pipe.
Described compound baffling artificial swamp, wherein, the surface grafting of bed body has the strong macrophytes of Radial Oxygen Loss from Root ability such as reed.
Described compound baffling artificial swamp, wherein, the bed body is brick mix structure.
Described compound baffling artificial swamp, wherein, the traverse baffle in the bed body is concrete structure.
The beneficial effects of the utility model are:
1) the utility model hydraulic flow state is complicated, and the actual hydraulic detention time of sewage prolongs.Top and bottom simultaneously water distribution have been improved the carbon source distribution situation effectively, and the removal effect of total nitrogen is outstanding.
2) water distribution is even, is difficult for stopping up.

Embodiment
The utility model provides the compound baffling artificial swamp that a kind of hydraulic flow state is complicated, the total nitrogen removal effect is good.
See also Fig. 1 and Fig. 2, the technical solution of the utility model is:
Compound baffling artificial swamp of the present utility model is comprised of the plant 5 of the filler 4 of filling in bed body 1, upper water-distributing device 2, lower water-distributing device 3, the bed body, artificial swamp surface grafting, traverse baffle 6, captation 7 and the rising pipe 8 in the bed body.
Bed body 1 is brick mix structure, and effluent seepage is processed to prevent through antiseepage around reaching in the bottom.The inner traverse baffle 6 that arranges of bed body is the Multi-level deflector plate of concrete structure, by upper and lower being staggered (as shown in Figure 2), to increase the complicacy of the inner hydraulic flow state of artificial swamp.
Be filled with three layers of filler 4 in the bed body 1, the orlop filler in the bed body is that (particle diameter is 20~30mm) to large particle diameter gravel, and the middle layer is that (particle diameter is 10~20mm) to middle particle diameter gravel, and the superiors are that (particle diameter is 5~10mm) to the small particle size gravel.
One side roof part of bed body is equipped with water-distributing device 2 (seeing also shown in Figure 3), one side bottom of bed body is equipped with lower water-distributing device 3, the multiple spot water distribution manner that adopts top and bottom to intake simultaneously, the water distribution ratio can be adjusted as required up and down, and water distributor all adopts " H " type perforated pipe (seeing also Fig. 4).Water outlet one side of bed body is provided with captation 7 (seeing also shown in Figure 5), adopts T-shape perforation header 8.
During the artificial swamp operation, sewage enters the packing layer of a body from top and the bottom of artificial swamp respectively simultaneously through upper water-distributing device 2 and lower water-distributing device 3, because bed body top dissolved oxygen levels is higher, and bed body bottom dissolved oxygen levels is lower, and the bed body is inner to form the different dominant bacteria aggregation zones such as nitrifying bacteria community and denitrification flora easily.The water-distributing device of top and bottom simultaneously water distribution has then been avoided conventional single-point water distribution to produce easily the carbon source deficiency causing anti-nitration reaction problem hard to carry on, for providing of anti-nitration reaction sufficient carbon source, can significantly improve the total nitrogen removal effect.Under the barrier effect of current at traverse baffle, turning back flows has prolonged the actual hydraulic detention time of sewage in filler, and hydraulic load and surging force also can keep certain stablizing in whole process, has reduced the possibility of packing layer obstruction and the area of slough.When sewage passed through the different zones of a body in turn, nitration reaction and anti-nitration reaction can hocket, and filler is purified sewage by the pollution substance in the effect removal sewage such as absorption, filtration, ion-exchange, complex reaction.
The plant 5 of artificial swamp is selected the strong macrophytes of Radial Oxygen Loss from Root ability such as reed, forms aerobic microenvironment around the root system of waterplant, and root exudates also provides nutritive substance for microbial growth and breeding, is conducive to removal of pollutants.Root system of plant also can absorb a part of pollutent that transforms in the sewage in addition.The pollutents such as the nitrogen phosphorus in the sewage are removed through the comprehensive action of Root of Wetland Plants, microorganism and filler, and the water after the purification is discharged system by rising pipe again after collect the catchment area.
