Abstract
The utility model relates to a pressure dissolved air float sewage treatment device. The pressure dissolved air float sewage treatment device comprises a float contact chamber and a separating chamber communicated with the upper part of the float contact chamber, wherein the lower part of the separating chamber is communicated with a fresh water outlet and a return water outlet, the return water outlet is positioned under the fresh water outlet, a sewage inlet is arranged under the float contact chamber, a sediment scraping device is arranged at the upper part of the float contact chamber and the separating chamber, the upper part of the separating chamber is communicated with a sediment discharge opening, an air dissolved water releasing head is connected with a pressure dissolved air tank, the pressure dissolved air tank is respectively connected with an air compressor and a water booster pump, and the water booster pump is connected with the return water outlet through a pipeline. The pressure dissolved air float sewage treatment device can effectively remove the waste residues after flocculation, and has the advantages of simple operation and convenient manipulation.
Description
Technical field
The utility model relates to a kind of waste disposal plant, is specifically related to a kind of pressure air-dissolving air-float waste disposal plant.
Background technology
Sewage disposal, according to the proportion size of its pollutent that contains, can selective precipitation or pneumatically supported mode remove pollutent.
The ultimate principle of air flotation technology is the logical people's air of Xiang Shuizhong, makes a large amount of micro bubble of generations in the water, by with the magazine particle adhesion to bubble, can form the buoyancy aid of proportion, last floatation surface, thereby a kind of process for purifying water of acquisition separating impurity less than water.The water inlet of air-float technology generally will be added flocculation agent and form flocs unit, in water, form the network-like structures of an inner filling water, its sedimentation speed is slower, and adhered to the flocs unit of a certain amount of microbubble, its proportion will be less than the proportion of water, the ascent rate of flocs unit is more faster than the sinking velocity of former flocs unit, and this just makes the air supporting method shorten dramatically than the solid-liquid separation time of the precipitator method.
The utility model content
The utility model provides a kind of improved pressure air-dissolving air-float waste disposal plant.
The utility model is achieved in that
A kind of pressure air-dissolving air-float waste disposal plant, comprise contact chamber, separate chamber with contact chamber top UNICOM, bottom, separate chamber and clear water output and recirculation water outlet UNICOM, the recirculation water outlet is positioned at the clear water output below, there is a sewage import contact chamber below, on contact chamber and top, separate chamber, be provided with a slag scraper, top, separate chamber and slag-drip opening UNICOM is characterized in that: be provided with a dissolved air water in the middle of the described contact chamber and discharge head, dissolved air water discharges head and is connected with pressure air-dissolving tank, pressure air-dissolving tank also is connected with an air compressor machine and pressure pump respectively, and pressure pump is connected with the recirculation water outlet by pipeline.
Further scheme is: the filter that also is provided with a level between described separate chamber and the slag-drip opening.
In the utility model, sewage through flocculation enters contact chamber from the sewage import, the bubble that discharges head release with dissolved air water meets, wadding grain and bubble adhesion, and slowly rise in the exposure chamber, enter the separate chamber with current then and carry out the pulp water separation, scum silica frost floats on the water surface and is removed by slag scraper, and waste residue is discharged by slag-drip opening.Being provided with of filter can avoid waste residue to enter into water once more.The generation of dissolved air water is to get the part clear water by the recirculation water outlet, pressurize through pressure pump, advance people's pressure air-dissolving tank, air compressor machine also blasts high-pressure air in pressure air-dissolving tank simultaneously, makes to be full of saturated air in the water, formed the high pressure dissolved air water, and come out to flow to from the bottom of dissolving and discharge head and discharge, because dissolved air water is through after discharging head and discharging, pressure drop is to normal pressure, the dissolved saturated air will discharge in the water, forms the floating use of micro bubble air feed.The utility model can effectively be removed the waste residue after the flocculation, and the device operation is simple, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of pressure air-dissolving air-float waste disposal plant, comprise contact chamber 2, separate chamber 4 with contact chamber top UNICOM, bottom, separate chamber and clear water output 7 and recirculation water export 8 UNICOMs, recirculation water outlet 8 is positioned at clear water output 7 belows, there is a sewage import 1 contact chamber 2 belows, on contact chamber 2 and 4 tops, separate chamber, be provided with a slag scraper 3, top, separate chamber and slag-drip opening 6 UNICOMs, also be provided with the filter 5 of a level between separate chamber and the slag-drip opening, be provided with a dissolved air water in the middle of the contact chamber and discharge 12, dissolved air water discharges 12 and is connected with pressure air-dissolving tank 11, pressure volume pot 11 also is connected with an air compressor machine 10 and pressure pump 9 respectively, and pressure pump 9 is connected with recirculation water outlet 8 by pipeline.
