Abstract
The present invention relates to a kind of making use of rain and flood bio-decontamination cycle wet land system, including being sequentially provided with impervious barrier, collector pipe channel layer, filtrate packed layer, the foundation ditch of plantation soil layer from top to bottom, precipitation defecator and integrated pump station is buried underground in filtrate packed layer, biological aggregate is filled in filtrate packed layer, biological aggregate includes building waste aggregate and adheres to the biomembrane formed by microbial bacterial agent outside it, some collecting conduit being connected with integrated pump station in collector pipe channel layer, the top of integrated pump station connects circulating water pipe.The effluent quality of the present invention can stably reach surface water IV class standard, do not limited by season and plant growing, use the micro-aeration of bottom and double oxygen supply patterns of top layer biology root system natural reaeration, have energy-conservation, ecological, the advantage that ambient adaptability is good, nothing is permanent takes up an area, and greenery patches, forest land, swag all can utilize, and can monitor with long-range by unmanned, substantially without operational and administrative expenses, construction investment is extremely low, constructs simple and convenient, and the duration is short.
Description
Technical field
The present invention relates to wet land system field, be specifically related to a kind of making use of rain and flood bio-decontamination cycle wet land system.
Background technology
Artificial swamp is by the ground similar with marshland manually built with control operation, and sewage has the dosing of control
To on the artificial wetland built, sewage and mud, during flowing in a certain direction, mainly utilize soil, are manually situated between
Matter, plant, the physics of microorganism, chemistry, biological triple synergism, a kind of technology that sewage, mud are processed.It is made
With mechanism include adsorbing, be detained, filter, oxidoreduction, precipitation, microbial decomposition, conversion, plant are covered, residue accumulated, steaming
Rise moisture and Nutrient Absorption and the effect of all kinds of animal.
One, Traditional Man wetland with the following drawback that and not enough:
1. floor space is big, it is desirable to have enough land areas.
2. easily being affected by pest and disease damage, summer, the water surface easily grew a large amount of mosquitos and flies.
3. longtime running easily blocks.
4. typically there is hydrops on surface, can only planting aquatic plants.
5. function singleness, only purification of water quality and water plant landscape function.
Two, tradition making use of rain and flood system with the following drawback that and not enough:
1. xoncrete structure or modular organization investment are huge.
2. plastic modular structural strength is poor, and earth's surface bearing capacity is limited, easily subsides.
3. longtime running easily blocks.
4. construction requirement is high, and engineering is long.
5. water quality purification function is weak, and early-stage rainwater needs abandoned stream.
Summary of the invention
It is an object of the invention to provide a kind of making use of rain and flood bio-decontamination cycle wet land system, having effluent quality can be steady
Surely reach surface water IV class standard, not by being limited in season and plant growing, construction investment extremely low, construct simple and convenient, the duration
The making use of rain and flood bio-decontamination cycle wet land system of the advantage such as short.
