Description
Technical field
The utility model relates to a kind of waste disposal plant, and specifically a kind of efficient micro-bubble oil removal by air bubbling is except the COD device.
Background technology
At present when sewage is processed, most enterprises all selects the air-flotation type water treating equipment that sewage is processed, the principle of work of air-flotation type water treating equipment is that gas is passed in sewage, make the bubble of γ-ray emission as the carrier of suspended substance, oils and part COD pollutent in sewage, make its buoyancy greater than gravity and resistance, thereby make pollutent float up to the water surface, form foam, be convenient to cleaning.But existing air-flotation type water treating equipment are only gas to be passed into form the effect that bubble realizes making the pollutent floating in air flotation pool, the most applications bubble not yet fully contacts with pollutent in air flotation pool and has just floated up to the water surface, so the sewage disposal time is longer, and the pollutants removal rate in sewage is lower.
The utility model content
The purpose of this utility model is to provide a kind of efficient micro-bubble oil removal by air bubbling except the COD device, the pollutants removal rate it can significantly improve sewage on the basis of effectively shortening the sewage disposal time in.
the utility model for achieving the above object, be achieved through the following technical solutions: comprise air flotation pool, weir divider is set in air flotation pool, weir divider is separated into soil chamber and water-purifying cavity with air flotation pool, soil chamber and water-purifying cavity top connection, slag scraper is installed at the air flotation pool top, the water-purifying cavity sidewall sets out the mouth of a river, the water-purifying cavity bottom is connected with return line one end, the return line the other end is connected with the fluid inlet of gas-liquid mixing pump, flow control valve is installed on return line, the relief outlet of gas-liquid mixing pump is connected with the import of microbubble generator by pipeline, the outlet of microbubble generator is connected with an import of T-shaped mixing tank by pipeline, another import of T-shaped mixing tank is connected with sewer line, bubble output tube in the outlet of T-shaped mixing tank and air flotation pool soil chamber is connected, set out pore on the bubble output tube.Install in the air flotation pool of slag scraper one end and deposit slag chute.Deposit worm conveyor is installed in slag chute.The bubble diffusion disc is installed on the production well on the bubble output tube.On pipeline between microbubble generator and T-shaped mixing tank, reducing valve is installed.Installing gas under meter on the inlet mouth of gas-liquid mixing pump.
The utility model has the advantage of: can guarantee that micro-bubble fully contacts with pollutent in sewage, pollutants removal rate significantly improve sewage on the basis of effectively shortening the sewage disposal time in, dirt can be concentrated rear continuous wave output, and during bubble floating, range of scatter is large etc.

Embodiment
a kind of efficient micro-bubble oil removal by air bubbling described in the utility model is except the COD device, comprise air flotation pool 1, the interior weir divider 2 that arranges of air flotation pool 1, weir divider 2 is separated into soil chamber 3 and water-purifying cavity 4 with air flotation pool 1, soil chamber 3 and water-purifying cavity 4 tops connections, slag scraper 13 is installed at air flotation pool 1 top, water-purifying cavity 4 sidewalls set out the mouth of a river 5, water-purifying cavity 4 bottoms are connected with return line 6 one ends, return line 6 the other ends are connected with the fluid inlet of gas-liquid mixing pump 7, flow control valve 16 is installed on return line 6, the relief outlet of gas-liquid mixing pump 7 is connected by the import of pipeline with microbubble generator 8, the outlet of microbubble generator 8 is connected with an import of T-shaped mixing tank 18 by pipeline, another import of T-shaped mixing tank 18 is connected with sewer line 10, bubble output tube 11 in the outlet of T-shaped mixing tank 18 and air flotation pool 1 soil chamber 3 is connected, set out pore on bubble output tube 11.During use, gas-liquid mixing pump 7 pumps into empty G﹠W in microbubble generator 8 simultaneously, microbubble generator 8 makes air produce a large amount of micro-bubbles in liquid, the micro-bubble that microbubble generator 8 produces fully mixes with the sewage that sewer line 10 passes into by T-shaped mixing tank 18, then together enter air flotation pool 1, suspended substance, oils and part COD pollutent that micro-bubble carries in sewage float up to the water surface, are convenient to slag scraper 13 cleanings.Weir divider 2 is separated into soil chamber 3 and water-purifying cavity 4 with air flotation pool 1, water outlet 5 is arranged on water-purifying cavity 4 one sides, said structure can guarantee that water and the micro-bubble in air flotation pool 1 has enough duration of contact, preventing that sewage from entering not yet just fully to contact with micro-bubble after air flotation pool 1 discharges from water outlet 5, is conducive to improve contaminant removal efficiency.The water that gas-liquid mixing pump 7 uses can be directly passes into from the water-purifying cavity 4 of air flotation pool 1, in order to control the flooding quantity of gas-liquid mixing pump 7, flow control valve 16 can be installed on the return line 6 between air flotation pool 1 and gas-liquid mixing pump 7.The utility model can guarantee that micro-bubble fully contacts with pollutent in sewage, the pollutants removal rate significantly improve sewage on the basis of effectively shortening the sewage disposal time in.
The utility model is cleared up for the ease of the dirt that slag scraper is struck off, and can deposit slag chute 14 in the interior installation of air flotation pool 1 of slag scraper 13 1 ends.But dirt periodic cleaning or adopt handling equipment outwards to carry after depositing that slag chute 14 is interior and concentrating.
The utility model can deposited the interior installation worm conveyor 15 of slag chute 14 for the ease of the dirt of depositing in slag chute 14 is carried out Automatic clearance.Worm conveyor 15 can outwards be carried the dirt of slag scraper 13 cleanings continuously.Certainly the utility model also can be made the scarp with depositing slag chute 14 bottom surfaces, dirt is outwards flowed by deadweight, but the transfer rate of this dirt mode of movement is slower, and easily blocks.
The utility model increases the contact probability of micro-bubble and sewage in order to increase the range of scatter of micro-bubble, and bubble diffusion disc 12 can be installed on the production well on bubble output tube 11.
