Abstract

The utility model provides a quasi-aerobic subsurface drainage artificial wet land, which comprises a main body and punched pipes. The main body is equipped with a water inlet and a water outlet; a water baffle is provided at the water inlet; a quarry stone layer, a pea gravel layer and a soil layer are filled in sequence from the top to the bottom of the main body; between the pea gravel layer and the soil layer, punched pipes are arranged in parallel horizontally; both ends of the punched pipes are opened to atmosphere through the main body; radial air outlets are provided on the punched pipes, in which macadams are provided. The utility model can effectively lower COD and such nutrient substances as nitrogen, phosphorus and etc in sewage water, so as to remove some untrient substances from the system through harvesting aquatic plants. The utility model is characterized in simple structure, small occupied area, low cost, stable operation, not easy to block, perfect treatment effects and high impact strength.

Description

Accurate aerobic drowned flow artificial wet land
Technical field
The utility model relates to drowned flow artificial wet land, belongs to the biologic treating technique field of dirty river sewage and sanitary sewage received.
Background technology
Artificial swamp is the emerging sewage treatment process that grows up the seventies in last century, because its construction and working cost is low, safeguard characteristics such as simple, effective, widely applicable has obtained using widely.According to the feature of current, artificial swamp can be divided into surface current wetland and current wetland.The surface current wetland easily grows mosquitos and flies summer, distributes foul smell, and floor space is big because the water surface is exposed in the air, and easily freeze winter, therefore less employing.Therefore the undercurrent type wetland has been because current in the wetland internal flow, have been avoided the shortcoming of surface current, and sewage abundant contacting substrate surface when flowing between the matrix slit, its adsorb and ion-exchange capacity much larger than surface current.Simultaneously, matrix granule provides a large amount of surfaces to supply microorganic adhesion, and the inner microorganism of wetland is abundant, and therefore load is bigger, and floor space is little, the sewage treating efficiency height.But because oxygen content is less in the matrix, form anoxic condition easily, influence normal growth of plant and the nitrification effect of microorganism.Drowned flow artificial wet land also exists blocking problem simultaneously, forms surperficial backwater easily.
Summary of the invention
The utility model is for remedying above-mentioned the deficiencies in the prior art, and a kind of simple in structure, with low cost, easy to operate, processing efficiency is high, floor space the is less accurate aerobic drowned flow artificial wet land of sewage disposal pond is provided.
The utility model adopts with following technical solution:
Accurate aerobic drowned flow artificial wet land comprises main body and perforated pipe, main body is provided with water-in and water outlet, the water inlet is provided with water eliminator, be filled with rubble layer, microlith layer and pedosphere in the main body from bottom to top successively, horizontal positioned has the perforated pipe that is arranged in parallel between microlith layer and pedosphere, the two ends of perforated pipe are passed main body and are communicated with atmosphere, and perforated pipe is provided with radially production well, are placed with rubble in the pipe.
Rubble and microlith adopt one of Wingdale and gravel.The particle diameter of rubble is 3-4cm, and the microlith particle diameter is 1-2cm.
Rubble layer, microlith layer and pedosphere three's height ratio is 6: 5: 3.
Perforated pipe adopts earthen-ware pipe or PVC plastics tubing.
During use, planting aquatic plants in the pedosphere.Select that durability against pollution is strong, well developed root system, diseases and insect pests resistance is strong, biomass is big advantage waterplant---giantreed, cattail and wild rice grass etc.
During operation, sewage is entered by the main body water-in, flows downward under the effect of water eliminator, through the rubble layer.Condition has been created in the biomembranous formation that exists for of rubble, helps filtration, absorption and the degraded of pollutent.Air enters treatment zone by perforated pipe, to replenish the deficiency of dissolved oxygen in the pond, promotes the nitrification of microorganism, has improved the nitric efficiency of sewage, and because plant obtains competent oxygen, well-grown; Because the feeding of air reduces the organism amount, impels miniature metazoan to produce simultaneously, can engulf more microorganism, has solved blocking problem.The root system of plant can absorb, assimilate nutritive substance and the hazardous and noxious substances in the sewage in the pedosphere.Sewage is discharged by water outlet behind the treatment zone of flowing through.
The utility model can effectively reduce nutritive substances such as the COD of sewage and nitrogen phosphorus, by the harvesting waterplant part nutritive substance of its absorption is removed from system.Have simple in structure, floor space is less, with low cost, stable, be difficult for to stop up, treatment effect is good, the characteristics of strong shock resistance

Among the figure: 1, main body, 2, rubble lime stone (or coarse gravel) layer, 3, microlith lime stone (or bird's-eye gravel) layer, 4, pedosphere, 5, water eliminator, 6, water-in, 7, water outlet, 8, perforated pipe, 9, plant.
Embodiment
Embodiment:
As shown in drawings, the accurate aerobic drowned flow artificial wet land of sewage disposal pond comprises main body 1 and perforated pipe 8.Main body 1 is rectangle, and is provided with water-in 6 and water outlet 7, and water-in 6 places are provided with water eliminator 5, and its effect is that matrix and water inlet are separated, and sewage is flowed downward.Be provided with rubble lime stone (or coarse gravel) layer 2, microlith lime stone (or bird's-eye gravel) layer 3 and pedosphere 4 in the main body 1 from bottom to top successively.The particle diameter of rubble lime stone (or coarse gravel) is about 3-4cm, and microlith lime stone (or bird's-eye gravel) particle diameter is about 1-2cm.Rubble lime stone (or coarse gravel) layer 2, microlith lime stone (or bird's-eye gravel) layer 3 and pedosphere 4 threes' height ratio is about 6: 5: 3.Horizontal positioned has the perforated pipe 8 that is arranged in parallel between microlith lime stone (or bird's-eye gravel) layer 3 and pedosphere 4.The two ends of perforated pipe 8 are passed main body 1 and are communicated with atmosphere.Perforated pipe 8 is provided with radially production well, is placed with rubble in the pipe.Perforated pipe 8 can adopt earthen-ware pipe or PVC plastics tubing.Sewage is entered by water-in 6, enters treatment zone by the bottom under the effect of water eliminator 5, and air is entered by perforated pipe 8, and sewage is finally discharged by water outlet 7.Plant in the pedosphere 4 and be implanted with plant 9.Plant 9 selects that durability against pollutions are strong, well developed root system, increment is big, diseases and insect pests resistance is strong aquatic dominant plant, as giantreed, cattail and wild rice grass etc.
The utlity model has following advantage:
1, simple in structure, with low cost, stable, treatment effect is good, strong shock resistance;
