Description
Technical field
The utility model belongs to technical field of sewage, is related to BAF.
Background technology
In recent years, with the fast development of industry, industrial wastewater and sanitary sewage are either from discharge capacity, or discharge
Species on, all there occurs huge change.A large amount of rows of wherein high COD, high-ammonia-nitrogen sewage and high ammonia nitrogen, low carbon-nitrogen ratio sewage
Whole sewage disposal system of being rivals in a contest proposes higher challenge.Wherein, BAF is a kind of life for being used to handle sewage
Thing reactor.Due to having the advantages that high treating effect, buffer capacity be big and safety and environmental protection, BAF is in sewage disposal
Had a wide range of applications in field.
Such as Chinese patent【Application number：201510169267.8；Application publication number：CN104817167A】Disclose a kind of use
It is used to solve the problem of filter is blocked in the precipitation position back-flushing method of UBAF technique, wherein on disclosed
Include distributing water room, filter plate, water distribution, gas distribution filter, supporting layer, filter material layer, clear water zone, backwash to stream BAF system
Drainage ditch, normal outlet canal, filter plate are fixed on the bottom in filter tank, and supporting layer and filter material layer are located at the top of filter plate, and filter is fixed
On filter plate, filter plate plays fixed and sealing function, and supporting layer and filter material layer is played a supportive role to water distribution, gas distribution filter.
In the prior art, there is following defect in BAF as disclosed above:Because filter is arranged on filter tank
Bottom and the lower section for being located at supporting layer and filter material layer again, that is to say, that when filter needs repairing replacing, maintenance personal needs to arrive
The bottom in filter tank carries out repair and replacement to filter, causes repair and replacement more troublesome, time-consuming；And due to supporting layer and filter material layer
It is pressed on filter, is unfavorable for filter and carries out maintenance replacing；Meanwhile, when being backwashed to filtrate, it is necessary to using water pump again
The clear water handled well is pumped from the bottom up filtrate is cleaned, energy resource consumption is big, be unfavorable for saving the energy and cost.
The content of the invention
The purpose of this utility model is there is above mentioned problem for existing technology, it is proposed that BAF, this reality
Technical problem with new solution is that the installation, maintenance and cleaning for how making filter tank more facilitate.
The purpose of this utility model can be realized by following technical proposal：BAF, including pond body, water outlet
Pipe, flush discharge pipe, water distribution distribution device, the filter plate in pond body and the filter being fixed on filter plate positioned at pond body bottom
Head, it is characterised in that the filter plate is fixed on the top of pond body and the inner chamber of pond body is separated into upper chamber and lower chambers, described
There is the delivery port communicated with outlet pipe in upper chamber, gravity type is formed between the delivery port and filter plate and rinses hydroecium, institute
Bottom chamber is stated provided with suspended filter material layer, the bottom chamber below suspended filter material layer is provided with the row communicated with flush discharge pipe
The mouth of a river.
It is different from prior art, filter plate is arranged on pond body by this BAF by changing the installation site of filter plate
Top, and filter material layer is arranged on to the lower section of filter plate, such maintenance personal just directly can deploy maintenance and installation from filter tank top
Work so that the installation and repair and replacement of filter plate and filter in pond body more facilitate, also, due under the pond body below filter plate
Suspended filter material layer in chamber can suspend so that installation, debugging and the repair and replacement of filtrate also more facilitate；Meanwhile, when
When filtrate needs to rinse, water distribution distribution device is closed, flush discharge pipe is opened, then using gravitional force, gravity type is rinsed
The water purification by filtering reserved in hydroecium can be backwashed to filter, filter plate and the suspended filter material layer of lower section, when in pond body
Water level fall back on suspended filter material layer, when below just stop rinse, that is to say, that this BAF utilize water gravitional force
Backwashed, it is not necessary to which water pump is set in addition, not only cause the cleaning in filter tank more to facilitate, and save the energy；Therefore, lead to
Designed more than crossing so that the installation, maintenance and cleaning of this BAF more facilitate.
In above-mentioned BAF, the bottom chamber below suspended filter material layer also have successively buffering area and
Water distributing area, the discharge outlet is located in water distributing area and close to the bottom of pond body.In backwash process, above-mentioned buffering area is set
Meter causes suspended filter material layer to be moved during water level decreasing in pond body, now, the extruding force that suspended filter material layer is subject to
Smaller, suspended filter material layer is in more open state, so that each filtering material particle can be mutual in backwash process
Frictional impact so that filtrate can clean it is cleaner, and then the cleaning of filtrate is more facilitated；Meanwhile, it is above-mentioned to set
Water state has been remained in meter buffering area so that suspended filter material layer can remain coherent condition, and discharge outlet is designed
In water distributing area and close to the bottom of pond body, so as to avoid the suspended filter material layer in backwash process from being discharged from discharge outlet.
In above-mentioned BAF, the distance between the delivery port and filter plate are 1.5m~2m.By above-mentioned
Distance design so that gravity type rinses hydroecium and ensure that the water of abundance is once clear to the part progress in the pond body of lower section
Wash, so that the cleaning in filter tank more facilitates.
In above-mentioned BAF, the suspended filter material layer is formed by multiple suspended filter material particle aggregations, is suspended
The density of filtering material particle is less than the density of water.Using above-mentioned design so that the installation, maintenance and cleaning of suspended filter material layer are more
Plus conveniently.
In above-mentioned BAF, the water distribution distribution device is located in the water distributing area, and the filter tank is also wrapped
Water inlet pipe and blast pipe are included, the water inlet of the water distribution distribution device is connected with water inlet pipe, the water distribution distribution device enters
Gas port is connected with blast pipe.By the reasonable Arrangement to above-mentioned water distribution distribution device position, ensureing BAF energy
While enough normal gas distribution and water distribution, cleaning that also will not be to filtrate in backwash process is impacted.
Compared with prior art, this BAF has advantages below：This BAF passes through to filter plate
The mode of installation site, filter material layer and filter back washing makes improvements so that the peace of filter, filter plate and filtrate in this filter tank
Dress, maintenance and cleaning more facilitate, and simple in construction, easily manufactured.
