Description
Technical field
The invention belongs to field of sewage treatment equipment, and in particular to a kind of air floatation machine.
Technical background
Air floatation machine is usually used in the intermediate treatment unit of sewage treatment project, and the particulate matter of the relatively lightweight in sewage is floated into removing with air supporting principle, reaches the purpose processed sewage.However, sewage is the mixture of a complicated component, there is large, medium and small in particulate matter, also there is weighing, heavier, lighter and light.It is big, in, it is lighter and light can preferably carry out air-flotation process, it is small, weight and heavier to be difficult to be processed, but also unnecessarily consuming part gas explosion declines the air-flotation process ability of air floatation machine.
The content of the invention
The technical problems to be solved by the invention are：For small, weight the and heavier impurity reluctant problem of common air floatation machine mentioned in technical background, the present invention provides a kind of air floatation machine that can remove small, weight and heavier impurity.
The technical solution used in the present invention is：
A kind of air floatation machine, including coagulating sedimentation system, air-flotation system, filtration system；Coagulating sedimentation system is made up of chemicals dosing plant, dosing pump, loading pipeline, stillpot, downflow weir, water inlet, water inlet is arranged on the top of stillpot, flocculant in chemicals dosing plant etc. is input in stillpot by dosing pump through loading pipeline, and downflow weir is set between stillpot and air flotation slot；Air-flotation system includes slag-draining device, deslagging pipeline, dissolving, reflux pump, aeration distribution lines and slag notch, reflux pump one end is connected in air flotation slot draws water, the other end is connected with dissolving, reflux pump in dissolving to being input into pressure-air simultaneously, high pressure in dissolving enters air flotation slot bottom rich in air water through being aerated distribution lines, is aerated, and slag-draining device is arranged on the top of air flotation slot, scum silica frost is entered into deslagging pipeline, is most discharged after slag notch；Filtration system includes corresponding pipeline and filter core, and last filter water is discharged by delivery port.
Further, the air floatation machine can install centralized control system, including switch board, display and control component etc..
Further, the slag-draining device is a kind of automatic slag discharge device.
The beneficial effects of the invention are as follows：Using flocculation sedimentation system except the impurity of duplicate removal, so as to alleviate the load of air-flotation system, air-flotation system removes lighter impurity, and filtration system removes less impurity, so as to reach the purpose of removal impurities in water comprehensively.
