Background technique
Air floating water purification technology be mainly used for removing density and water phase it is close, can not natural subsidence be difficult to the suspension that nature floats again
Impurity has many advantages, such as that separative efficiency is high, equipment is simple.Just development is more slow for the technique functions, until the microbubble seventies produces
The raising of raw technology is just rapidly developed, be widely used in the processing of oily waste water and dyeing waste water, paper pulp deinking,
Soil improvement, algae and removal of heavy metal ion etc..
Flotation waste water treatment process can simply be summarized are as follows: hydrophobic contaminants in water and the hydrophobicity interspersed among in water are small
Bubble collides under certain hydraulics, is adhered to each other by intermolecular Van der Waals force, in buoyancy float downward to water
Face and remove；In addition, it also include in water biggish hydrophily floccule body caught by net, build bridge and the effects of winding capture it is micro-
Minute bubbles, virtue of buoyancy act on the process for floating to the water surface and being removed.
Airfloat equipment is the required unit of flotation waste water treatment process, and performance directly affects the treatment effect and expense of waste water.
According to bubble producing method, airfloat equipment be broadly divided into air-dissolving air-float equipment, air-dispersing airfloat equipment, electrical floating apparatus, biology and
Chemical floatation equipment.Every kind of airfloat equipment can be subdivided into a variety of patterns again, and it will not go into details, only briefly introduce several typical air bearings and set
Standby and its applicable cases.
Pressurized dissolved air flotation equipment is dissolved in air under the action of certain pressure in processing water, pressure general 0.2
~0.6MPa, then reduces to normal pressure suddenly, be dissolved in the air of water just in the form of micro-bubble bubble (diameter is generally 20~
100 μm) it is escaped from water, dross is formed floating to the water surface together with the suspended matter adherency in water, then scum trough is discharged by Slag Scraping Device
It is removed, clear water is then flowed out by flotation tank lower part, realizes solid- liquid separation.Pressurized dissolved air flotation equipment mainly by air dissolving system,
The three parts such as gas releasing system and separation system composition.According to the type of suspended matter contained in waste water, property and degree for the treatment of
Difference, and whole pressurized dissolved air flotations, part pressurized dissolved air flotation and three kinds of partial reflux pressurized dissolved air flotation can be divided into.Pressurization
The bubble of air-dissolving air-float equipment is subtle, epigranular, closeness are big, air-flotation process significant effect, stabilization, and entire technique mistake
Journey and equipment are fairly simple, and convenient for management, maintenance, therefore application is relatively broad, can be used for various wastewater processing, are particularly suitable for
The processing of oily waste water.
Utility model content
