Description

Isolated heterogeneous balanced air-floating apparatus
Technical field
The invention belongs to the physical method for separation field, relate in particular to a kind of isolated heterogeneous balanced air-floating apparatus.
Background technology
Air supporting is to utilize the micro-bubble of high dispersing for carrier goes to adhere to pollutants in waste water, makes its density float to the water surface on less than water, thereby divides dried up and water treatment method suspended substance.Make also that tensio-active agent floats attached to bubble surface in the water, thereby and water sepn, foam air supporting method be called.The equipment that the air supporting method is used comprises the air flotation pool of accomplishing sepn process and the auxiliary facility that produces bubble.In the water treatment, the air supporting method can be used for the inapplicable occasion of the precipitator method, approaches water and is difficult to sedimentary suspended substance to separate proportion, and for example grease, fiber, algae etc. also can be in order to concentrate active sludge.
Principle: the suspended substance surface has hydrophilic and branch hydrophobic.The hydrophobic nature particle surface adheres to bubble easily, thereby available air supporting method.Hydrophilic particle can transfer hydrophobic nature to after handling with suitable pharmaceutical chemicals.Air supporting method in the water treatment, coagulating agent commonly used are formed colloidal solid to be flco, and flco has network structure, voids easily, thus improve daf efficiency.Moreover, can form foam if any tensio-active agent (like washing composition) in the water, the effect that suspended particle rises together of adhering to is also arranged.
The bubble production method: produce the method for microbubble, commonly used have two kinds of aeration air supporting method and dissolved air flotations.Also have electrolytic process in addition, but be of little use.
Electrolytic process: electrolytic process is the direct current that in sewage, feeds 5 ~ 10V, thereby produces micro-bubble, but because power consumption large electrode plate is prone to fouling, so be mainly used in the Industrial Wastewater Treatment of middle and small scale.
Aeration air supporting method: aeration air supporting method is claimed the dispersion air method again, is in the bottom of air flotation pool micropore diffuser plate or diffuser tube to be set, and pressurized air slave plate face or pipe face are overflowed in water with the micro-bubble form.The mounted impeller in the bottom, pond is also arranged, and wheel shaft is perpendicular to the water surface, and pressurized air leads to the impeller below, and the stirring action when borrowing the impeller high speed rotating is cut into small bubbles with air pocket.
Dissolved air flotation: be dissolved in the gas in the water, when water surface air pressure reduces, just can from water, overflow.Two kinds of methods are arranged: space on the air flotation pool is is vacuum state, be in and promptly disengage microbubble after current under the normal pressure enter the pond, claim the vacuum air soluble method; 2. air pressurized is dissolved in the water and is reached capacity, and the decompression of dissolved air water stream disengages microbubble when getting into air flotation pool, claims the pressure air-dissolving method.The latter is comparatively commonly used.Pressure air-dissolving water can be all or part of of institute's treating water, also can be the recirculation water of air flotation pool water outlet, and the backflow water yield accounts for the per-cent of the water yield of handling and claims reflux ratio, is the important factor that influences daf efficiency, must be confirmed by test.The equipment of pressure air-dissolving method has force (forcing) pump, dissolving and air etc.Dissolving is the pressure-bearing steel cylinder, inner standing flow deflector or the placement filler put.The dissolving water outlet gets into air flotation pool through reducing valve or reliever.
Separate no matter above-mentioned each prior art is solid-liquid separation or liquid liquid, all can produce tail gas, but but can not accomplish the tail gas after separating is isolated, more can not toxic and harmful in the tail gas after separating effectively be absorbed; On the contrary, tail gas can spill into air, especially works as the workman near air-floating apparatus, and when perhaps air-floating apparatus being overhauled, the toxic and harmful in the tail gas will endanger health of human body.
