Abstract

The utility model relates to an aerobic filtration tank with inflated aeration, which is provided with two box bodies, wherein, one box body is provided with a dissolved air releaser and a water inlet, a water outlet pipe is connected with the bottom of the second box body, and an inflation pipe for backwashing air and inflating oxygen is also arranged in the second box body. In addition, the utility model is also provided with a gravel pad layer and an anthracite layer, the suspended floc particles in water can be removed through air flotation as secondary treatment, and the dissolved matter in water can be further removed through aerobic oxygenation, filtering and backwashing. The utility model has strong purifying capacity and can greatly increase the water quality after filtering.

Description

Aerobic filtration tank with inflated aeration
The utility model belongs to a kind of waste disposal plant, relates to the sewage purification technology field.
At present, sewage second-level treating water deep purifying adopts coagulation basically--precipitation (clarification)---filter, the device that is adopted can remove the suspended matter in anhydrating, thereby has removed most of BOD, COD, has also reduced colourity and turbidity simultaneously, making purifies waste water is bordering on clarification, transparent, but reuse water after treatment also contains the organic substance of suitable concentration, makes its application be subjected to certain limitation, can on refrigerating unit, produce foundry loam, increase the trouble of maintenance management.
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, thereby provides a kind of air supporting to inflate aerobic filter tank, can strengthen the removal ability of suspended substance, improves the level that purifies water.
The purpose of this utility model realizes in the following way:
This device is made up of casing (1) and casing (2), wherein, casing (1) front end has dissolved air release (3) and water-in (4), middle and lower part at casing (1) back segment also has water shoot (6), water shoot (6) is linked the bottom of casing (2), be evenly equipped with through hole on the water shoot in the casing (2), the bottom of casing (2) also has the gas-filled valve (7) that carries out air backwash and oxygenation, the interior bottom of casing (2) is gravel blanket (8), the middle part is anthracite coal measure (9), the top has drainage tray (10), also has through hole on gas-filled valve (7).
During use, secondary treated wastewater is after flocculation reaction, enter water tank (1) from water-in (4), dissolved air water reliever (3) discharges many micro-bubbles, stick on the suspension floc particle, thereby the flocculation particle is risen slowly, and the water surface forms scum silica frost, regularly or is continuously discharged by slag-drip opening, primary water enters casing (2) by water shoot (6), behind aeration aerating, dissolved oxygen water flows into filtering layer again, discharges through drainage tray, owing to brought up an aerobic filter space, promote the breeding and the metabolism of aerobic microbiological, form microbial film at filter material surface, the vital movement of microorganism has just further been removed the dissolved organic matter matter in the secondary water.As guarantee certain biochemical reaction time, also can with NH4-N nitrated be nitrate, also produce denitrification reaction in microbial film inside.
The utility model compared with prior art has following advantage:
This device adopts air-float purification, compare with common settling tank, be easy to remove the suspended sludge fragment in the secondary treated wastewater, improve the transparency of purifying waste water, also in secondary water, carried out aeration aerating, good gas filters biochemical reaction and the crown_interception that can facilitate full filtering layer, and guarantee certain biochemical reaction time, under aerobic condition, full filtering layer all dams and biochemical reaction, increase space and time that machinery cuts dirty and biochemical reaction to greatest extent, can improve filter back water quality significantly.
Below in conjunction with accompanying drawing and practical example the utility model is described in detail:
Fig. 1 is a structure iron of the present utility model, also is an embodiment.
In Fig. 1: (1) casing; (2) casing; (3) dissolved air release; (4) water-in; (5) slag-drip opening; (6) water shoot; (7) gas-filled valve; (8) gravel blanket; (9) hard coal filtering layer; (10) drainage tray.
Embodiment: have small pore on the dissolved air release, can in water tank, produce micro-bubble after connecting air driven pump, casing can be by metal or concrete prefabricated forming, around the turnover pipe, use bituminous seal during installation, adopt the thick ANTHRACITE FILTER MEDIA of particle size in the casing (2), carry out air backwash and oxygenation at this.The hard coal particle diameter is 2-3mm; The gravel particle diameter is 4-8mm.This device is compared with legacy equipment, and BOD, COD clearance improve 30%, and the NH4-N clearance improves 20-30%, and intestinal bacteria and removal of bacteria rate significantly improve.

Claims (2)

1, aerobic filter tank is inflated in a kind of air supporting, form by casing (1) and casing (2), it is characterized in that: casing (1) front end has dissolved air release (3) and water-in (4), middle and lower part at casing (1) back segment also has water shoot (6), water shoot (6) is linked the bottom of casing (2), be evenly equipped with through hole on the water shoot in the casing (2), the bottom of casing (2) also has the gas-filled valve (7) that carries out air backwash and oxygenation, the interior bottom of casing (2) is gravel blanket (8), the middle part is anthracite coal measure (9), and the top has drainage tray (10).
2, aerobic filter tank is inflated in air supporting according to claim 1, it is characterized in that: gas-filled valve also has through hole on (7).
