Abstract
The invention discloses a diversion-type horizontal subsurface flow constructed wetland reactor, belonging to the field of sewage treatment. The diversion-type horizontal subsurface flow constructed wetland reactor comprises a box body (1), a water distribution pipe (2), a water collecting pipe (3), a guide plate (4), a perforating baffle (5) and a perforating water distribution inclined plate (6). As the rear of a treatment area of the reactor is provided with the guide plate, the flow state distribution of sewage inside the reactor can be optimized, and the phenomena of flow break and short flow of the reactor can be reduced. As a water distribution of the reactor is provided with the perforating inclined plate, the water distribution uniformity of the sewage can be improved, the suspended matters of the sewage entering into the treatment area of the reactor are reduced, the blocking phenomenon of the reactor can be avoided and weaken, and the removing effect of the sewage is improved.
Description
Technical field
The present invention relates to technical field of sewage, specifically is a kind of diversion-type horizontal subsurface flow constructed wetland reactor that is used for WWT, belongs to green technology.
Background technology
The proposition of artificial wet land sewage treating process and technology and develop into comprehensive solution water pollution problem a kind of new selection is provided.Artificial wet land system can be divided into subsurface flow constructed wetland system and surface current artificial wetland system according to the different of water flow mode and structure; Subsurface flow constructed wetland system can be divided into vertical current constructed wetland system and horizontal flow artificial wetland system again.Artificial swamp has obtained application more and more widely as secondary or three grades of Sewage treatment systemss in sewage treatment area.Artificial swamp has advantages such as investment low with working cost (be merely traditional B-grade sewage factory 1/10～1/2), anti-shock loading, treatment effect are stablized, effluent quality is good.In addition, artificial wet land system also has nearly nature and landscape effect concurrently.
Make progress from present domestic and international research; Artificial wet land system is after being provided with and constructing well, along with the prolongation of working time, because the heterogeneous body conductivity of wetland inner stuffing; Moreover the microbial film thickness that adheres on the filler is different; Finally cause sewage at the artificial swamp rear portion fluidised form skewness, usually cutout or short flow phenomenon can appear at the rear portion of horizontal drowned flow artificial wet land, this will weaken the removal efficient of artificial wet land system to pollutent in the sewage greatly.In addition, it is inhomogeneous water distribution to occur usually at horizontal drowned flow artificial wet land forward water distributing area, and causes sewage in water distributing area, to flow with the orifice flow fluidised form, and does not reach the homogeneity to the water distribution of sewage, and the pollutant removal of dewing ground treatment zone impacts.Therefore, need a kind of horizontal drowned flow artificial wet land reactor drum that can solve and overcome above-mentioned defective of invention.
Summary of the invention
The present invention provides a kind of diversion-type horizontal subsurface flow constructed wetland reactor, be intended to solve constructed wetland reactor water distribution inhomogeneous with cutout, short flow phenomenon on the problem and shortage that occurs, a kind of novel artificial wetland reactor drum is provided.
Technical scheme provided by the invention is following:
A kind of diversion-type horizontal subsurface flow constructed wetland reactor mainly comprises reactor drum casing (1), reactor water distribution pipe (2), reactor drum header (3), flow deflector (4), perforated retainer (5), perforation water distribution swash plate (6).Wherein casing (1) is a cuboidal configuration, and concrete size: length * wide * height is 1400mm * 500mm * 1000mm; Reactor drum is joined, to adopt diameter be that the pvc pipe of 32mm is made for header (2), (3); The perforation of perforated retainer (5) is arranged as penetration hole diameter 10mm, hole back gauge 10mm; The perforation of perforation water distribution swash plate (6) is arranged as penetration hole diameter 8mm, and that hole back gauge 10mm flow deflector is of a size of is long * and high in 400mm * 600mm; Reactor drum is separated into water distributing area, treatment zone and catchment area three parts by perforated retainer (5), and every partial-length is respectively 200mm, 1000mm and 200mm.The fluidised form distribution of sewage in reactor drum optimized in being provided with of reactor for treatment district rear portion flow deflector, reduced the appearance that reactor drum cutout occurs, lacks flow phenomenon.In the reactor drum water distributing area middle punch swash plate the water distribution uniformity that has improved sewage is set, reduce the suspended substance that gets into sewage in the reactor for treatment district, can avoid and weaken the latch up phenomenon of reactor drum, improved the removal effect of sewage.Reactor material adopts the hard polyethylene board of thick 15mm to make.
Innovative point of the present invention is:
1, the diversion-type horizontal subsurface flow constructed wetland reactor of the present invention fluidised form that can optimize reactor for treatment district water flow inside distributes, reduce and avoid occurring stopping, the appearance of latch up phenomenons such as short stream, for the long-term continuous service of reactor drum provides assurance.
2, the setting of diversion-type horizontal subsurface flow reactor water distribution district uniform water distribution swash plate has improved sewage at the inner water distribution uniformity of water distributing area, has weakened the pollution load of artificial swamp treatment zone.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
A kind of diversion-type horizontal subsurface flow constructed wetland reactor system mainly comprises reactor drum casing (1), reactor water distribution pipe (2), reactor drum header (3), flow deflector (4), perforated retainer (5), perforation water distribution swash plate (6).Wherein casing (1) is a cuboidal configuration, and concrete size: length * wide * height is 1400mm * 500mm * 1000mm; Reactor drum is joined, to adopt diameter be that the pvc pipe of 32mm is made for header (2), (3); The perforation of perforated retainer (5) is arranged as penetration hole diameter 10mm, hole back gauge 10mm; The perforation of perforation water distribution swash plate (6) is arranged as penetration hole diameter 8mm, hole back gauge 10mm; That flow deflector is of a size of is long * and high in 400mm * 600mm; Reactor drum is separated into water distributing area, treatment zone and catchment area three parts by perforated retainer (5), and every partial-length is respectively 200mm, 1000mm and 200mm.The fluidised form distribution of sewage in reactor drum optimized in being provided with of reactor for treatment district rear portion flow deflector, reduced the appearance that reactor drum cutout occurs, lacks flow phenomenon.In the reactor drum water distributing area middle punch swash plate the water distribution uniformity that has improved sewage is set, reduce the suspended substance that gets into sewage in the reactor for treatment district, can avoid and weaken the latch up phenomenon of reactor drum, improved the removal effect of sewage.Reactor material adopts the hard polyethylene board of thick 15mm to make.
Sewage at first passes through water distributing pipe (2) and gets into reactor water distribution district (I), by perforation water distribution swash plate (6) uniform water distribution, makes sewage obtain the flow velocity in consistent entering reactor for treatment district (II) then, thereby reaches the purpose of uniform water distribution.The sewage that gets into wetland treatment zone (II) through plant, filler and the mikrobe of over-wet land treatment zone act synergistically jointly handle after; Under the guide functions of the flow deflector (4) of wetland set inside; Make the inner flow-shape of treatment zone be more evenly distributed, thereby reduced the generation of latch up phenomenons such as treatment zone appearance cutout and short stream.Sewage is handled the back through treatment zone and is collected eliminating by the interior header in catchment area (III) (3), finally reaches the purpose of WWT.
