Description

A kind of processing system using water in biological aerated filter system
Technical field
The utility model is related to sewage-treatment plants, and in particular to a kind of system by based on biological aerated filter is handled Sewage is to obtain the processing system of middle water.
Background technology
Biological aerated filter becomes in the industry BAF, is a kind of Novel sewage bio membrane treatment, has fabulous denitrogenation With organic matter degradation effect, with the water standard that the level-one A standards and municipal sewage that reach sewage discharge recycle, aeration is given birth to Object filter tank technology is to grow microorganism in its surface and clearance gap by a kind of biofilter material of novel ball lightweight via Film, flows into upwards or from top to bottom filter material layer, and filter material layer lower part provides aeration.Sewage flows through the filtrate that surface covers with biomembrane When, organic matter and nitrogen therein are degraded, while SS in biological filter bed of material retention sewage and the aging biomembrane that falls off are gone forward side by side Row is separated by solid-liquid separation.Periodically using treated, water outlet backwashes filter tank.It excludes the SS that is trapped and aging falls off biology Film promotes falling off for filter material surface mouse biomembrane, so that the fresh bio film of high activity is in direct contact with sewage, improve degradation Rate and efficiency ensure standard water discharge.
The working method of water, whole mistake during the aerating biological filter sewage processing system of municipal administration composite wastewater obtains at present Filtering velocity degree is slow, can not handle big load technique, and the especially big impurity of kitchen sewage viscosity is not readily separated filtering, and working efficiency is low.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of processing system using water in biological aerated filter system System, carbon nitrogen aeration and nitrogen are aerated to form two level aeration filtration, while design scheme improves filter efficiency and middle water quality, save Equipment place.
The technical solution adopted in the utility model is as follows:
A kind of processing system using water in biological aerated filter system, including pass sequentially through the elevator pump of sewage conduct connection Room, preposition settling tank, level-one biological aerated filter, two level biological aerated filter, sand filter, middle pond and backwash buffer pool;It waits for The sewage of processing is delivered to after grid is handled in the lift pump room, the preposition settling tank bottom be equipped with it is several it is vertical every Plate is deposited in the sludge of bottom of pond to be isolated,
It is provided with right motor-driven blade wheel in the strainer of the sand filter, chemical feed pipe is installed on the blade wheel, The chemical feed pipe is equipped with several nozzles;
The middle pond is respectively that the level-one biological aerated filter, two level biological aerated filter and sand filter provide backwash With water, is drained after the backwash of the level-one biological aerated filter, two level biological aerated filter and sand filter to backwash and buffered respectively Chi Zhong, the backwash buffer pool are connected to the input terminal of preposition settling tank by water pump and pipeline.
The rotating speed of the processing system of water in above-mentioned biological aerated filter system, the blade wheel is 20-30r/min.
The processing system of water in above-mentioned biological aerated filter system, the preposition settling tank are conventional precipitation pond or hydrolysis acidification Pond, the level-one biological aerated filter are that decarburization nitrifies filter tank, and the two level biological aerated filter is nitrification filter tank.
The beneficial effects of the utility model are:Dosing is to stir dosing by blade wheel, ensures that liquid is uniform, infiltration is good It is good, water quality in raising.Meanwhile by backwash water pump, the water during scene utilizes in pond provides backwash for three filter tanks, saves A large amount of places occupy, and reduce the use of back-washing equipment, save cost.
Description of the drawings
Fig. 1 is the system structure diagram of the utility model embodiment;
Fig. 2 is the structural schematic diagram of the filtering ponds of the utility model embodiment;
In figure:1 be grid, 2 be lift pump room, 3 be preposition processing pond, 4 be level-one biological aerated filter, 5 be two level expose Gas biofilter, 6 be sand filter, 7 be middle pond, 8 be backwash buffer pool, 31 be partition board, 61 be blade wheel, 62 be chemical feed pipe, 63 be nozzle.
Specific implementation mode
The utility model is further explained below in conjunction with the accompanying drawings.
In diagram, water pump is used when P1, P2 and P3 are water deliverys in pipeline, B1 and B3 are Aeration fan, and B2, B4 and B5 are equal For backwash wind turbine.
Kind utilizes the processing system of water in biological aerated filter system, it is characterised in that:Connect including passing sequentially through sewage conduct The lift pump room 2 that connects, preposition settling tank 3, level-one biological aerated filter 4, two level biological aerated filter 5, sand filter 6, middle pond 7 With backwash buffer pool 8;Pending sewage is delivered to after the processing of grid 1 in the lift pump room 2, the preposition settling tank 3 Bottom is equipped with the sludge that several vertical partition boards 31 are deposited in bottom of pond with isolation,
It is provided with right motor-driven blade wheel 61 in the strainer of the sand filter 6, is equipped with and adds on the blade wheel 61 Pencil 62, the chemical feed pipe 62 are equipped with several nozzles 63;
The middle pond 7 is respectively that the level-one biological aerated filter 4, two level biological aerated filter 5 and sand filter 6 provide Anti- scouring water is drained respectively after the backwash of the level-one biological aerated filter 4, two level biological aerated filter 5 and sand filter 6 to anti- It washes in buffer pool 8, the backwash buffer pool 8 is connected to the input terminal of preposition settling tank 3 by water pump and pipeline.
