Description
Technical field
The present invention relates to biological water purification fields, more particularly to a kind of perpendicular stream reinforcing formula biological water purification device and process for purifying water.
Background technology
Biological water purification technology is currently used non-point source pollution control technology, have the unique hydrology, physics, chemistry,
The characteristics such as biology can not only form distinctive biocoene habitat, be provided simultaneously with filtering, sedimentation, remove external source pollution
Ability.In recent years, biological water purification technology derives various devices, technique simple, small investment, quick advantage in its method
It is developed rapidly.
Artificial swamp is Typical Representative therein.Artificial wetland process is broadly divided into two type of surface low formula and undercurrent type
Type.The water level of surface low formula artificial swamp is shallower (being generally no greater than 60cm), relies primarily on the absorption purification of wetland plant
Sewage.In relation to studies have shown that surface low formula artificial swamp is because of the simple absorption for relying on plant, clean-up effect is extremely limited,
And organic nitrogen phosphorus can be released into water body again by Litter with the degradation of microorganism.
The water level of underflow type artificial wet land is relatively deep (generally more than 60cm), does not only rely on the absorption of plant, and
By the filtering of filtrate, suction-operated and be attached to filter material surface microbiological deterioration realize sewage purification, to have
It is standby to compare surface low formula artificial wet land system more preferably purifying property.But traditional underflow type artificial wet land is in actual operation still
In the presence of take up a large area, water reoxygenation is poor, short stream, easily stifled etc. knotty problems.
Underflow type artificial wet land system fights for valuable land resource because taking up a large area, with agricultural land.Therefore logical
The purification efficiency for improving unit area wetland is crossed to save its occupation of land, becomes the important side of biological water purification technology and process modification
To.
Because water level is deeper, filtrate gas permeability after longtime running biofilm weakens underflow type artificial wet land system, causes reoxygenation
Scarce capacity, this becomes common recognition already.When water hypoxia, the aerobic decomposition of nitrification and organic matter of microorganism will be by
Inhibit, therefore there is an urgent need for the dissolved oxygen levels of underflow type artificial wet land water body are promoted using cost-effective mode.
Short stream is that it's showing for water time shortening pasts to underflow type artificial wet land the sewage caused by unsmooth flowing in actual operation
As.The shortening of water time is crossed so that wet land system cannot achieve the complete nitrification of ammonia nitrogen, and then limit the further anti-nitre of nitrogen
Change so that the total nitrogen of water body can not be up to standard after processing.In addition, the suspension particulate matter (SS) in sewage easily blocks wetland filter
Material, causes to stop.Therefore the short stream of underflow type artificial wet land and blockage problem are urgently to be resolved hurrily.
In addition, if the plant of underflow type artificial wet land cannot clear up in time after decaying, the cauline leaf and root system of plant will be rotten
It is rotten, organic pollution materials are released, the organic loading of wet land system is further exacerbated by.Therefore the load carrying of wet land system is improved
Power is also a kind of actual needs.
In order to make up traditional underflow type artificial wet land reoxygenation it is poor, easily block, easily it is short stream, the serious deficiency of secondary pollution, this
Invention proposes a kind of novel biological water purification device.
Invention content
To achieve the purpose of the present invention, the present invention proposes a kind of perpendicular stream reinforcing formula biological water purification device, including：Up-flow
Well, drop stream well, advection pipe and recycle stream water purification medium.
In perpendicular stream reinforcing formula biological water purification device proposed by the present invention, the up-flow well and drop stream well are vertically provided at described
In recycle stream water purification medium；The advection pipe is set between up-flow well top and the tops drop Liu Jing, and the two is connected to；The liter
Stream underground portion and drop stream underground portion are equipped with several through-holes；It is equipped with aeration plate in the up-flow well, is set in the drop stream well
There is biofilm carrier filler；The recycle stream water purification medium is laid on the up-flow well and drops the outside of stream well, between dielectric layer
Lay non-woven fabrics；The recycle stream water purification medium top surface can plant wetland plant.
Preferably, the laying height of recycle stream water purification medium exceeds the perpendicular stream reinforcing formula biological water purification device normal water level
5~10cm of line；
Preferably, the shape of up-flow well and drop stream well is cylinder, is made of reinforcing bar concrete placings or the modes such as brick；
Preferably, a diameter of 5~20cm of well is flowed up, the recycle stream water purification medium 10~20cm of top surface is highly exceeded；
Preferably, a diameter of 15~50cm of drop stream well, highly exceeds the recycle stream water purification medium 10~20cm of top surface.
Aeration plate in the up-flow well uses diaphragm microporous aeration disc, is supplied by the air blower being set on wetland ground
Gas, aeration disk diameter are slightly less than the diameter of up-flow well；
Preferably, the carrier filler in drop stream well uses artificial synthetic fiber or plastics, such as：Polyethylene (PE), polypropylene
(PP), reinforced polypropylene (RPP), chliorinated polyvinyl chloride (CPVC) and poly- inclined alkene (PVDF) etc. are made, the filling rate of carrier filler
It is 65%~95%.
The lower part of the up-flow well and drop stream well is equipped with several through-holes, and through-hole diameter is 1~3cm, and quantity is 10~
It 50, is uniformly distributed within the scope of 5~50cm of shaft bottom or more.
Preferably, advection pipe is set between up-flow well top and the tops drop Liu Jing, and the up-flow well and drop stream well are connected
It is logical；
Preferably, the setting height of advection pipe is flushed with the recycle stream water purification medium top surface；
Preferably, advection pipe uses cast iron or PVC material, a diameter of 5~15cm, tube wall sealing.
The recycle stream water purification medium is laid on the outside of the up-flow well and drop stream well, is from top to bottom followed successively by coarse sand
