Description
Technical field
The utility model relates to waste water control equipment, and landscape water purifying processing device more precisely can be widely used in the purifying treatment of the landscape water body of leisure, public place of entertainment.
Background technology
The view water system is that people lie fallow, one of the important place of amusement.The water source of landscape water body mainly comprises rainwater, river, underground water, tap water, middle water etc.The general less natural water design of press of landscape water body, so all be the very weak closed system of self-purification capacity mostly, and because the input of the unreasonable and foreign matter of its internal structure is easy to produce eutrophication, final water body is polluted, and the function of landscape water body also is affected.
Summary of the invention
At present, treatment processs such as chemical dosing, increase filter plant are adopted in the improvement of landscape water body mostly.Though these methods have been improved water quality at short notice, also environment has been caused secondary pollution simultaneously, and had the handling problem of later stage operation.
Recently, people begin to seek the ecological management measure of landscape water body, as application number is 200710037851.3, and the patent that name is called " polymer fibre high speed filtering device of landscape water body, river course water and former water treatment " provides a kind of speed filtering device based on macromolecular fibre.The main out of order synergetic mode of particulate state macromolecular fibre that adopts of this device produces the cross flow filter effect, and by membrane separation technique landscape water body is purified.Though this device filtration velocity is fast, effective, needs additionaling power that landscape water is transported to device, and in the process of life-time service, also have problems such as the obstruction of filler and replacing.In addition, this filtration unit also need be established the clear water water source in addition when backwash regularly, uses for operation and makes troubles.
The utility model content
The utility model uses vertical diafiltration principle, adopts the bionical processing mode that comes from nature, simulating nature, constructs compound lakebed, has fundamentally solved the non-ecological property of present water body treating mode, and the water quality that is caused can't satisfy the present situation of user demand.
This device is made of impervious barrier, filter layer, water-permeable pipe and collection tube.Be provided with many perforation water-permeable pipes around the bottommost macrobead layer of filter layer, collection tube is terminal to communicate with water-permeable pipe, collects the water that oozes down.Collection tube is laid to the bank below ground, and on underground collection tube flow control valve is set, with the size and the adjusting water level of the control diafiltration water yield.
The utility model distinguishing feature: 1, low-cost, low investment; 2, operation maintenance cost is low, does not need electromechanical equipment; 3, water body purification is effective, simulates natural wet land system, and improves water body purification ability, non-secondary pollution in conjunction with physics and biological dual function; 4, grating layer macrobead has bigger specific surface area, helps microbial growth, increased the effect of microorganism to contaminant degradation, improved the landscape water treatment effect; 5, treatment effect is not subjected to the influence of external environment factors such as temperature, season; 6, can be in conjunction with view physical features flexible design, vertical diafiltration zone, natural purification are infiltrated in pending muddy landscape water gravity flow; 7, need not to change filler, need not regular recoil, run duration does not need personnel on duty.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
The technical solution of the utility model is an example with view lake water.This device is made of impervious barrier 6, filter layer 1, water-permeable pipe 2 and collection tube 3, the device shape can be set in conjunction with landscape water bottom lakebed, be provided with impervious barrier 6 in filter layer 1 bottom, many perforation water-permeable pipes 2 distribute on the impervious barrier 6, collection tube 3 ends communicate with water-permeable pipe 2, are furnished with flow control valve 4 on the collection tube 3.
The lakebed regional area of view lake water is dug deeply, the lakebed bottom is provided with impervious barrier 6, from bottom to top fill 400mm-500mm graded sand and stone 7,600-1000mm fine sand 8,300mm planting soil 9(growing area from impervious barrier 6 then) or the non-growing area of cobble 10() etc., constitute vertical filter layer 1.The fine sand layer 8 of particle diameter≤4mm can be sneaked into a certain proportion of diatomite in right amount, to increase the effect of removing the graininess suspended substance.
Graded sand and stone 7 is pressed the descending layer of cloth successively from bottom to top of particle diameter:
Thickness is that 100mm-200mm, particle diameter are the macrobead layer 7-a of 30-120mm;
Thickness is about 100mm, particle diameter is the middle granular layer 7-b of 20-30mm;
Thickness is about 100mm, particle diameter is the small-particle layer 7-c of 10-20mm;
Thickness is about 100mm, particle diameter is the fine particle layer 7-d of 4-10mm.
The macrobead layer can adopt pebbles, speed to divide materials such as biochemistry ball (patent No. ZL 200820108330.2) or big stone.Because speed divides biochemical ball that bigger specific surface area is arranged, and helps microbial growth, has increased the effect of microorganism to contaminant degradation, can further improve the landscape water treatment effect.
This device is covered with many parallel perforation water-permeable pipes 2 that spacing is 1.5-2.0m around the macrobead layer 7-a of graded sand and stone, water-permeable pipe 2 ends link to each other with collection tube 3, are used to collect down the water that oozes.Have the aperture that diameter is 10mm in the both sides of water-permeable pipe 2 tube hubs, interval 200mm between every group of aperture.The outside surface of water-permeable pipe 2 surrounds with macrobead layer 7-a, in case its aperture is blocked.
Because action of gravity during successively by fine sand layer 8, grating layer 7, the fine suspension in the water body will be owing to deposition, the filteration in lakebed diafiltration district when landscape water body, is trapped and finally by microbiological degradation, water body further is purified.Landscape water body is collected by the water-permeable pipe 2 that is embedded among the macrobead layer 7-a of lakebed bottom through behind the filtration, purification, converges to vertical diafiltration district 1 outer collection tube 3.Collection tube 3 needs to lay to the bank below ground, and on underground collection tube 3 valve 4 is set, with the size and the adjusting water level of the control diafiltration water yield.If there is the ground potential difference in landscape lake, the lake water in the collection tube 3 can utilize its terrain, flows into the landscape water body in low district 5, downstream certainly.If there is not the ground potential difference in landscape lake, collection tube 3 shops are provided with winding shaft to the below ground of bank, lake water is promoted to lake surface cloth water spot.
Non-growing area at the lakebed center, lay pebbles 10 is to reach the effect of beautification of landscape; In Vlei zone, fill 300mm planting soil 9 near loke shore.In conjunction with landscape design, emergents such as growing area plantation cattail, Scirpus tabernaemontani, Spiked Loosestrife, reeds, to increase the natural degradation ability of water body.
In order to keep the landscape water life-time service, in operational process, annual winter, lake water was generally understood emptying, can remove the mud on lakebed and top, vertical diafiltration district during emptying.Or look practical operation situation, if obstruction is more serious, but the granular layer partial update in vertical diafiltration district.
