Description
Technical field
The utility model relates to a kind of waste disposal plant, specifically is meant a kind of air-floating apparatus that carries out WWT through air supporting, mechanical subsidence style.
Background technology
Environmental pollution has become a social concern of China, and especially in the rural area, water pollution has reached corresponding serious degree, and to the country of this lack of water of China, the recycling of waste water control and water is the challenge of pendulum in face of us.
To the present pollution condition of China, the method for disposing of sewage is a lot, and domestic a lot of enterprises have done a lot of work in this regard, have also obtained certain effect.Dare not use problem but good multiple enterprises also exists, in fact also with not rising, so many enterprises would rather be punished and be reluctant to start sewage disposal device, major cause is that cost is too high.So solving the cost of the present WWT of China is the important problem that will solve in the environmental improvement process, the while in like manner can not form secondary pollution improvement sewage.
The utility model content
The utility model proposes easy to operate, an economical and practical device to the problem in the present environmental pollution improvement.The utility model is achieved through following proposal:
A kind of air-floating apparatus that is used for WWT; Comprise reaction zone, air flotation zone, sedimentation catchment area, header, porthole, dividing plate; It is characterized in that reaction zone is furnished with dosing mouth, be communicated with through ventpipe between reaction zone and the air flotation zone, separate through the air supporting baffle plate between air flotation zone and the sedimentation catchment area; Header, mud collection bucket are arranged in the sedimentation catchment area, the mud collection bucket be positioned at header below.The collection of mud is that the deadweight according to mud itself drops to the mud collection bucket, then through following opening discharger.
As preferably, above-mentioned a kind of reaction zone that is used for the air-floating apparatus of WWT is divided into equal-sized 3 ~ 7 sub-districts.This mainly is to consider that sewage is convenient to sewage after ingress 1 has added medicine and the medicine adequate time is reacted, and reaches effect preferably, thus through several sub-districts are set, with sewage successively along the channel flow mistake that each sub-district was arranged in, the admission passage mouth.The number that the sub-district is set certainly has a variety of factors to decide, and in the utility model, being arranged to 3 ~ 7 is to decide according to the factors such as reaction times that cost, sewage type, medicament and sewage are set.
As preferably, the above-mentioned a kind of air outlet of ventpipe in device that is used for the air-floating apparatus of WWT is positioned at the device bottom, and its position is lower than the porthole position of sewage from reaction zone entering air flotation zone.
As preferably, the air supporting baffle plate of above-mentioned a kind of air-floating apparatus that is used for WWT and porthole at same horizontal plane, be oppositely arranged, form 30 ~ 60o angle with dividing plate, opening up.The effect of dividing plate is to blur at air flotation zone to be divided into two zones again, is boundary with the air supporting baffle plate basically.One side of air supporting baffle plate has the porthole, is to belong to air supporting, be mixed into the master, and the opposite side of air supporting baffle plate then is sedimentation, catchmenting is separated into the master.As for, the air supporting baffle plate is wanted shape to have a certain degree to be agitated from above by gas to gush out, get into the sedimentation side because help sewage.Through the air supporting baffle plate at a distance from retaining, can guarantee to help steady relatively at sedimentation, the side of catchmenting liquid sedimentation, catchment, otherwise effectively sedimentation and catchmenting.
As preferably, above-mentioned a kind of header that is used for the air-floating apparatus of WWT is positioned at the bottom of device, and the gully-hole on the header communicates with the outside water collecting basin of device.
In the utility model; Such setting is to fully take into account the effect of ventilation in this device just to design, and when sending into air flotation zone to gas through ventpipe, gas can be heaved the sewage that gets into air flotation zone from the porthole; Further thorough mixing; Make foreign material flocculation, conglomeration, the separate easily of sewage, thus have only be arranged on the air outlet below, can play effect preferably.
The beneficial effect of the utility model: this device is simple to operate in the process of disposing of sewage, and is easy for installation, use cost is cheap, and clean effect is very good.

Embodiment
Below in conjunction with accompanying drawing, a specifically statement is done in the enforcement of the utility model:
Embodiment 1
According to accompanying drawing 1, structure shown in Figure 2; Making one is used for the air-floating apparatus of WWT, comprises reaction zone 7, air flotation zone 10, sedimentation catchment area 11, header 2, porthole 5, dividing plate 4, and wherein reaction zone 7 is furnished with dosing mouth 8; Be communicated with through ventpipe 6 between reaction zone 7 and the air flotation zone 10; Separate through air supporting baffle plate 3 between air flotation zone 10 and the sedimentation catchment area 11, header 2, mud collection bucket 1 arranged in sedimentation catchment area 11, mud collection bucket 1 be positioned at header 2 below.Described reaction zone 7 is divided into equal-sized 4 sub-districts.The air outlet of ventpipe 6 in device is positioned at the device bottom, and its position is lower than sewage gets into air flotation zone 10 from reaction zone 5 positions, porthole.Air supporting baffle plate 3 and porthole 5 at same horizontal plane, be oppositely arranged, form 30 ~ 60o angle with dividing plate 4, opening up.Header 2 is positioned at the bottom of device, and the gully-hole on the header 2 communicates with the outside water collecting basin of device.Before sewage being handled at every turn, should do one to the composition of sewage and measure, the kind that helps confirming the add-on of medicament like this and add medicament can fully be handled sewage.
Be transported to reaction zone 7 to sewage from sewage import 9 through the pump housing, when the pump housing is carried sewage, add a certain amount of chemical agent through dosing mouth 8 simultaneously, foul and chemical agent in the sewage are reacted.According to the required time of chemical reaction and the flow of sewage, can be arranged to some reactions sub-district, the order that connects sewage along each sub-district is current, arrives the porthole 5 at dividing plate 4 places then, and reacted sewage 5 enters into air flotation zone 10 through the porthole.When sewage just enters into air flotation zone 10, by below gush the gas that ventpipe 6 bloats that passes through that gets off and be filled with, give thorough mixing once more.And the gas that sewage is filled with bloats from the upper end of air supporting baffle plate 3 and proceeds to sedimentation, catchment area 11.In sedimentation, catchment area 11, less because of the effect that receives external force, sewage is in the natural subsidence state basically; Foul flocculates in settling process gradually, drops to the mud collection bucket 1 of the bottom of device always; And water is drawn by header 2, up to the outside water collecting basin of device, and can recycling.
Certainly, in the utility model, can arrange what of header, and the size of gully-hole that also can be on header is confirmed according to the size of the foul that is flocculated according to the amount of catchmenting.
