Description
Technical field
This utility model is related to a kind of high-efficiency fibre filter for strengthening denitrification function by grafting biologic packing material, concrete to belong to
In water-treatment technology field.
Background technology
State Council formally promulgates " ten, water " within 2015.From 2016, endemicity water pollution control preventing and treating is put into effect more
Plan, further refines " ten, water ".From the point of view of policy, generally emphasize that sewage treatment plant carries mark, surface water environment and carries mark and city
The improvement of city's black and odorous water.And sewage treatment plant puies forward mark transformation project and becomes the first step work that each place government makes.
Show according to living to build portion's urban wastewater treatment firm real-time management system, by by the end of June, 2015, national cities and towns add up
Build up sewage treatment plant 3802, wherein one-level A project only 860, the sewage drainage standard of major part sewage treatment plant of China
For one-level B standard, and a sewage treatment plant is from one-level B discharge standard to the additional investment of one-level emission standard A, at this
The 50%-70% of reason factory original capital cost, this pen are invested no matter for enterprise or government, a undoubtedly huge throwing
Money.To reduce cost of investment, it is in-depth two stage treatment and increase depth that most of Sewage Plant is carried and marks the treatment measures for transforming selection
Process.
High-efficiency fibre filter is a kind of brand-new gravity one, is a kind of common deep treatment method, extensively should
Carrying in mark transformation project for sewage treatment plant's one-level A to one-level B.Due to factors such as climate, geographical environment, water quality situations
Affect, the project not up to standard of each sewage treatment plant is not quite similar.For some Sewage Plants, after two stage biological process,
To COD, BOD5、SS、NH3The major pollutants clearance such as-N is higher, water outlet majority parameters value reached one-level A or
The level of one-level A is close to, and now only discharge standard just need to can be reached through high-efficiency fibre filter again by adding flocculant；
And for some Sewage Plants, secondary effluent advanced nitrogen is still difficult point, this causes mainly due to denitrification effect is bad
Nitrate nitrogen too high levels, so as to cause TN not up to standard, this is accomplished by further improving the new processing equipment of handling process or increase,
May result in cost of investment significantly to increase.
In sum, if it is possible to combine water quality characteristicses, increase on the basis of original high-efficiency fibre filter and carry out a biological disposal upon
Technology, strengthens denitrification function so that TN, COD, NH3The pollutant such as-N, TP are obtained into one after processing through two stage biological
Filtered through high-efficiency fibre filter after step degraded again, can not only so ensure standard water discharge, and substantially reduce cost of investment.
The content of the invention
This utility model purpose is to provide a kind of high-efficiency fiber filter for strengthening denitrification function by grafting biologic packing material

It is fixed at the top of lower filter plate 6；The biologic packing material 2 and fiber filtering 4 respectively have some groups, from upper between upper filter plate 1 and lower filter plate 6
And under be divided into microbial reaction area and filtering area, wherein, some groups of biologic packing materials 2 are located in microbial reaction area, and some groups are fine
Dimension filtrate 4 is located in filtering area.
In this utility model, every group of biologic packing material 2 is list structure, the biologic packing material 2 by axial cord and several
Biologic packing material unit is constituted, and axial cord side-by-side mounting has biologic packing material unit, non-cross between each biologic packing material unit.
In this utility model, each biologic packing material unit may be selected the various fillers for being easy to build microbial film, such as thread
In filler, laminal filter or hydrophilic filler etc. any one；The axial cord may be selected plastic ties, cordage, nylon rope or not
In rust steel cable etc. any one.
In this utility model, each biologic packing material unit lower end is connected with 2 groups or more than 2 groups fiber filterings 4, it is ensured that fiber
Filtrate is filled up, and is easy to filter tank backwash to discharge the pollutant being trapped, and
Guarantee that backwash process reaches minimum to the Biofilm formed on biologic packing material.
In this utility model, the upper connector 3 can select plastics with biologic packing material axial cord one, material
In rope, cordage, nylon rope or stainless steel cable etc. any one.
In this utility model, the upper connector 3 and lower connector 5 reserve certain excess length, i.e. upper connector 3,
Fiber filtering 4 and 5 three's length sum of lower connector more than filtering area height, when in high-efficiency fibre filter filter process, fiber
Filtrate 4 is compressed, or when every group of 4 backwash of fiber filtering is stretched, because there is a certain amount of richness with lower connector 5 in upper connector 3
Remaining length, therefore vertical displacement will not occur.
In this utility model, biologic packing material is set up in fiber filtering filter tank front end, biologic packing material can be carried as biomembrane
Body, on the premise of fiber filtering filter is not affected, intensified anti-nitrated can act on, and strengthen the clean-up effect to sewage.
As biologic packing material has huge specific surface area, can be with microorganism intrinsic in absorption effluent, so as to form a kind of microorganism
Mycoderma.Different types of micropopulation is grown on these Microbe membranes, TN that can be unnecessary in fast degradation water body,
COD、BOD5、NH3The pollutant such as-N, TP.
Biologic packing material itself with ductility, water body flow characteristic can be changed, be conducive to showing in biologic packing material
The external environment condition of anaerobic- anoxic- oxic is formed, the removal effect of nitrogen is greatly improved.
In addition, this utility model does not limit biologic packing material material, biologic packing material can be adjusted according to water quality situation
Material, biofilm condition, reaction condition, to reach the enhancement process effect to certain specific pollutants.For example, by increasing micropore
Aeration improves aerobic treatment efficiency, improves to NH3- N, NO2The removal of-N etc.；Improved by using hydrophilic filler and detested
Oxygen biochemical treatment rate, improves the removal to COD etc..
High-efficiency fiber filter material filter pool is combined by this utility model with technology of biological membrane, neither affects fiber filtering filter tank
Filtration, and the removal effect to nitrogen, phosphorus, BOD5, COD etc. can be improved.
