Description
Technical field
The invention belongs to the multistep treatment fields of a kind of water, waste water or sewage, and in particular to a kind of sewage treatment process.
Background technique
Sanitary sewage and various industrial wastewaters are the principal elements for causing water pollution at present, are contained in sewage a large amount of organic
Pollutant and nitrogen etc. lead to water hypoxia because oxygenolysis consumes a large amount of dissolved oxygens, make water after being discharged into surface water body
Body environment is destroyed.A large amount of sewage discharge also results in the waste of water resource in addition to leading to water pollution, so using suitable
Water treatment technology processing sewage and by treated reusing sewage in life or production be very necessary.
Currently, sewage water treatment method is more, used filter is also varied.Wherein, floating living bed technique is
Biofilm and activated sludge process are organically combined, to promote the organic pollutant removals rate such as COD, BOD in activated Sludge System
With increase denitrification effect.This technology can effectively promote 2~4 times of the volumetric loading of activated sludge tank, and by nitrification and instead
Nitrification carrys out degradable organic pollutant and realizes effective denitrogenation.Its filter generally uses the mistake of top water inlet bottom water outlet
Filter mode, sewage are entered by filter top, and after filter layer filters, clear water is discharged by filter bottom.Water-treated
Cheng Zhong, biological bed thickness constantly thicken, and cause pressure transient in filter, and water resistance is big, and energy consumption is high, in filter operation
Easily blocking, needs frequent progress to backwash, and not only water consumption is big, but also effluent quality is unstable after backwash, influences water process
Effect, and filler service life is short, and cost of water treatment is high.
A kind of sewage treatment process and its equipment are disclosed in the patent document that patent publication No. is CN101580327, it should
The device of sewage treatment process uses float bed filter, is equipped with the floating bed being made of suspension media from the bottom to top in filter
Filter layer, sandstone filter layer, water inlet pipe pass through each filter layer from top to bottom and are passed through floating bed filter layer or less.Sewage is by aeration
Afterwards, it is passed through by water inlet pipe self-relocation bed filter layer lower part, the microorganism in water is attached to suspension media surface and forms life of floating
Object filter bed, sewage pass sequentially through from the bottom to top floating living filter bed, sandstone filter layer filtering, clear water by filter top
Overflow discharge, sludge are discharged by the discharge outlet for being located at filter lower part.Although being had using the sewage treatment process and its equipment
Filter bed resistance is small, and consume energy low advantage, but after filtering a period of time, pollutant can be gradually adhered to the table of filter bed
Face causes the rate of filtration slack-off, or even blocking filter bed, influences subsequent filter effect.
Summary of the invention
The purpose of the present invention is to provide a kind of sewage treatment process, can be avoided pollutant using the process filtration sewage
It is persistently attached to filter bed surface, to guarantee filter effect.
In order to achieve the above objectives, base case of the invention is as follows:
A kind of sewage treatment process, is filtered using float bed filter, and the float bed filter includes shell, floats
The water inlet pipe of cavity is equipped in dynamic bed filter layer and tube wall, shell is divided into upper cavity and cavity of resorption by the floating bed filter layer

The gas distribution head connect, gas distribution head are equipped with the solarization air cap being connected to the cavity, are additionally provided with and are connected by pipeline and cavity
Logical aerator；The technique specifically includes following processing step,
(1) directly the sewage of processing is added in the lower chamber of shell by water inlet pipe, then starts aerator；
(2) control the aeration quantity of aerator as follows: a. presses 5m3The throughput of/s drum into the cavity of water inlet pipe
Enter air, continues 2-3 hours；B. after step a terminates, the throughput of aerator is increased as 20m in 1-2s3/ s,
Floating bed filter layer is lifted by moment at this time, stops aeration 2-3min after being aerated 5-10min, and floating bed filter layer falls at this time,
Circulation step a and step b later；
(3) when aerator works, Air Exposure is carried out in the lower chamber of shell, while to sewage to be processed, it is dirty
Water and air filters through floating bed filter layer and enters upper cavity；
(4) enter the intracorporal water of epicoele and handle completion.
The advantages of this programme, is:
1, in the present solution, being filtered and Air Exposure simultaneously in float bed filter, what aerator generated has
Cavity of the air of pressure through water inlet pipe is simultaneously discharged from the solarization air cap in gas distribution head, carries out at aeration while filtering
Reason can preferably support microorganism and provide oxygen, thus by the more complete of sewage treatment；Meanwhile air passes through floating bed filter layer, it will
Pollutant in floating bed filtering lamellar spacing is taken out of, can prevent floating bed filter layer from blocking；
2, when being aerated using the aeration mode of this programme circulation step a and step b, when by 5m3The throughput of/s is to water inlet
Air is blasted in the cavity of pipe, is now in the stage of normal processing sewage；After step a terminates, aeration is set in 1-2s
It is 20m that standby throughput, which increases,3Floating bed filter layer can be lifted moment by/s at this time, and aeration process generates a large amount of air, empty
Gas ruptures after touching floating bed filter layer, and the pollutant shake being attached in floating bed filtering layer surface is fallen；Then stop exposing
Gas, floating bed filter layer can fall at this time, and stronger relative motion occurs for floating bed filter layer and the intracorporal water of cavity of resorption, will be attached
Floating bed filtering layer surface pollutant take away, thus avoid floating bed filter layer block.
Prioritization scheme 1, advanced optimizes base case, connects between floating bed filter layer upper end and case top
It is connected to spring.It is 20m when the throughput of aerator increases3Floating bed filter layer can be lifted moment by/s at this time, and spring is pressed
Contracting, after step a and step b, under the elastic force of spring and the collective effect of floating bed filter layer, floating bed filter layer is fast
Speed moves down, and reinforces the degree of the relative motion of sewage and floating bed filter layer, is conducive to improve the effect for removing attachment pollutant.
Prioritization scheme 2, advanced optimizes base case, is equipped with air storing cavity in the floating bed filter layer, it is described into
The side wall of water pipe is equipped with connection cavity, and the gas vent that can be connected to air storing cavity；Further include following processing step: chamber is intracorporal
Air enters air storing cavity by gas vent, and the air in air storing cavity is upward, flows downward, and will be blocked in floating bed filter layer
Contaminant exclusion.During processing, floating bed filter layer can be slided up and down along water inlet pipe, when sliding into gas vent and gas storage
When chamber is connected to, air enters air storing cavity, and the air in air storing cavity is upward, flows downward, and will come into floating bed filtering interlayer
Pollutant in gap is discharged by gas, and extend floating bed filter layer uses the time.
Prioritization scheme 3 advanced optimizes base case, prioritization scheme 1,2 any one, and the water inlet pipe lower part is equipped with
Elastic plate identical with floating bed filter layer bottom surface size, the elastic plate can be contacted with floating bed filter layer, further include following step
It is rapid: to be collided when floating bed filter layer moves down with elastic plate, elastic plate shakes off the pollutant for being attached to floating bed filter layer.
