Description

Air floating sewage treatment plant
Technical field
The utility model relates to a kind of waste disposal plant, is specifically related to a kind of air floating sewage treatment 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 a bubbling air in water, makes a large amount of micro bubble of generation in the water, by with the magazine particle adhesion to bubble, can form the buoyancy aid of proportion less than water, last floatation surface, thereby obtain a kind of process for purifying water of separating impurity.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 air floating sewage treatment plant.
The utility model is achieved in that
Air floating sewage treatment 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, on contact chamber and top, separate chamber, be provided with a slag scraper, top, separate chamber and slag-drip opening UNICOM, it is characterized in that: described contact chamber bottom and flocculating chamber UNICOM, top, flocculating chamber is provided with a sewage import, inside, flocculating chamber is provided with a whipping appts, is provided with a dissolved air water releasing tube in the middle of the contact chamber, and the dissolved air water releasing tube is connected with knockout drum, knockout drum is connected with air dissolved pump, and air dissolved 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.
Further scheme is: described air dissolved pump is turbulence pump or gas-liquid multiphase pump.
In the utility model, air dissolved pump adopts turbulence pump or gas-liquid multiphase pump, its principle be at the ingress of pump air in water enters pump case, the impeller of high speed rotating repeatedly cuts into small bubbles with inhaled air, be dissolved in the water rapidly under the hyperbaric environment of small bubbles in pump, the formation dissolved air water enters air flotation pool then and finishes the air supporting process.During the utility model work, at first extract the water of recirculation water outlet as recirculation water by air dissolved pump, produce dissolved air water, dissolved air water discharges into by the dissolved air water releasing tube in the water of exposure chamber, and small bubbles slowly rise and adhere on the impurity particle, forms the buoyancy aid of proportion less than water, last floatation surface, form scum silica frost, and move forward with sluggish flow and to enter the separate chamber, by slag scraper scum silica frost is removed then.Clear water is regulated discharging through overflow, thereby finishes pneumatically supported working process.Sewage adds from the top of flocculating chamber, stirs the small bubbles that produce in the dissolved air water that flco and bottom by the flocculating chamber enter the exposure chamber by flocculation and contacts, and float.The utility model technology is simple, and energy consumption is low, and less investment is convenient to promote.
