Referring to accompanying drawing 10, the present invention works like this: first water outlet chamber 23 is injected into clear water, and swill enters water inlet chamber 11 by water inlet pipe 38, and the oily water after filter residue frame 2 intercepts larger particles and floats such as vegetable leaves by inlet The water overflow weir 17 flows into the water inlet level control chamber 12, and the water inlet overflow weir 17 ensures that the slick oil in the water inlet chamber 11 enters the water inlet level control chamber 12 preferentially, preventing the slick oil from accumulating in the water inlet chamber 11, The water inlet level control chamber 12 sends oil and water to the dissolved air contactor 4 in the three-phase separation chamber 21 through the water inlet mixing pipe 3 to perform three-phase separation of oil, water and slag. At this time, the dissolved air pump 26 sucks the air Fully mixed with the inhaled water outlet chamber 23 clear water to become dissolved air water, which is sent to the dissolved air contactor 4 together with oil and water through the dissolved air pipe 9 and the water inlet mixing pipe 3 for air flotation separation. After the dissolved air water and oil water are mixed, the fine oil droplets are wrapped by the microbubbles released by the fine dissolved air water to form a gas-oil complex, the density becomes lighter, and the upward flow rate is accelerated, and the gas-oil complex rises to the top of the dissolved air contactor 4 The gathering of reflectors 5 becomes larger, accelerating its ascending flow velocity. In the three-phase separation chamber 21, the fine slag settles in the slag collection hopper 20, and the oil droplets brought out by the gas-oil combination enter the upper oil collection area through the central through hole 16 of the oil collection and discharge cover 6. After being collected on 6, it enters the oil storage chamber 24 through the oil outlet hole 31, and then is discharged from the oil discharge pipe 29, and the separated water enters the water outlet ring pipe 7 through the water inlet hole 32 and enters the outlet water level control chamber 22 through the outlet pipe 37. Then enter the water outlet chamber 23 through the water outlet overflow weir 27 and be discharged by the drain pipe 28, and the fine slag settled in the slag collecting bucket 20 is discharged by the slag discharge pipe 8, and the water inlet hole 32 on the water outlet ring pipe 7 keeps the surrounding water evenly, At the same time, it reduces the fluctuation of water and creates a relatively stable environment for the separation of oil, water and slag. After the dissolved air water and raw water are mixed, the fine oil droplets are wrapped by the microbubbles released by the dissolved air water, the density becomes lighter, the rising flow rate is accelerated, and the separation effect of oil and water is improved. The reflection plate 5 utilizes the inclined plate principle and the shallow layer theory to accelerate the accumulation of small oil droplets into larger oil droplets, which facilitates the air flotation separation of oil and water, and at the same time, due to its separation effect, it avoids contact with the water flow under the oil collection and drainage cover 6 Fluctuation affects the stability of oil discharge. The dissolved air pump 26 is automatically controlled. It starts when water enters and stops for one minute after the water flow stops, so as to ensure the full separation of oil, water and slag, and save electric energy at the same time.
