(3) utility model content
The purpose of this utility model provides a kind of Net box pollutant control device, solve existing permeable reactive wall pollution treatment poor effect, cost height, the not easily changeable technical problem of filler.
For achieving the above object, the utility model adopts following technical scheme:
This Net box pollutant control device, comprise the intravital active reaction filler of body of wall and wall, it is characterized in that: its body of wall is the cage structure of layering combination shape, net cage with current wall forward be that boxboard by the rigid dense board making surrounds and forms, the net cage inherence is fixed with at least four layers of permeable separate mesh perpendicular to upstream face, the permeable separate mesh of each floor is separated at least three lattice chambers with net cage inside, the indoor mineral filler that is equipped with of feed-water end lattice chamber and water side lattice, the middle indoor active reaction filler that is equipped with of layout, net cage is extended with the filtrate flow deflector to the direction that meets water.
Can there be two lattice chambers, three lattice chambers in the layout chamber or more than the three lattice chambers in above-mentioned.
Above-mentioned rigid dense sheet material can be stainless steel plate, concrete slab, plastic plate or glass epoxy.
Above-mentioned permeable separate mesh can be plastic wire or chemical fiber web.
Above-mentioned mineral filler can be the mixing material of quartz sand, slag, wilkinite, above two or three material.
Above-mentioned active reaction filler can be one or more a mixing material of reductive agent, complexing agent or the sorbent material of zero-valent metal powder, gac, ion exchange resin, phosphoric acid salt, chitin, zeolite, Wingdale, organic clay, degradable volatile organic matter.
Above-mentioned filtrate flow deflector can be the hood-shaped or toroidal of canopy.
The utlity model has following beneficial effect: than known PRB wall water treatment better effects if, can continue in-situ treatment, but process element is many, processing power is strong, price is relatively cheap, the active reaction filler is changed convenient, can effectively remove the pollution substances such as heavy metal, inorganic anion, organism, nitrate, vitriol and phosphoric acid salt in the underground water.The utility model is provided with perpendicular to the groundwater flow direction, adopts the cage type structure, and permeable separate mesh makes whole net cage be divided into several compartments, makes each filler in the net cage conveniently replaced.Required medium and the layering of active reaction filler is filled in the ready-formed net cage in the net cage; mineral filler is loaded in the first lattice chamber of each net cage and last lattice chamber; mineral filler plays filtration, buffering and supports provide protection in treating processes; the active reaction filler is loaded in middle layout chamber, and the active reaction filler can play the effect that strengthens organic biodegradability, adsorb organic compound, removal ammonia nitrogen in sewage treatment process.The kind of active reaction filler and ratio can be set in advance according to the pollutent of locality, when polluted underground water passes through, pollutent transmits with pre-designed packing medium by nature waterpower and contacts, pollutents such as dissolved organism, metal, nucleic are degraded, adsorb, precipitate, react or remove, and underground water is purified.
In addition, also be connected with the filtrate flow deflector on the net cage, this filtrate flow deflector can play the effect of collecting sewage.Even there is the bigger situation of pollutent area, also can effectively collect sewage.Need not to improve cost, increase reaction wall size.
The utility model is a kind of groundwater pollution in-situ treatment method, is generally perpendicular to the groundwater flow direction, is installed in pollutent easily from the soil body of underground water the evolving path.
(4) description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is a plan structure synoptic diagram of the present utility model;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Reference numeral: 1-feed-water end lattice chamber, 2-middle layout chamber, lattice chamber, 3-water side, 4-permeable separate mesh, 5-net cage, 6-filtrate flow deflector.
(5) embodiment
Embodiment is referring to shown in Fig. 1-3, and this Net box pollutant control device comprises body of wall and the intravital active reaction filler of wall, is provided with in the groundwater flow position that meets water, and opening direction is towards the direction that meets water.Its body of wall is the cage structure of layering combination shape, net cage 5 with current wall forward be that boxboard by the rigid dense board making surrounds and forms, above-mentioned rigid dense sheet material can be stainless steel plate, concrete slab, plastic plate or glass epoxy.The net cage inherence is fixed with at least four layers of permeable separate mesh 4 perpendicular to upstream face, and above-mentioned permeable separate mesh 4 can be plastic wire or chemical fiber web.Permeable separate mesh 4 is separated into five lattice chambers with net cage 5 inside.
