The use of the utility model device: press shown in the accompanying drawing 1, meal the kitchen personnel open the lid (14) at top, Separation of Solid and Liquid chamber (5) earlier, changing food waste poured in the filter bag (13) of band mesh, then, lid (14) closed; Swill in the changing food waste is subjected to the downward cascade filter bag of the effect of gravity (13) and filter bores dividing plate (15), drop in the housing (11) of water-oil separating chamber (1), solid waste in the changing food waste is collected in the filter bag (13), after the solid waste in the filter bag (13) is filled, meal the kitchen personnel take out filter bag (13), and the sealing sack, lay in or be transported to treatment plant temporarily and implement recycling; With the filter bag (13) of new band mesh replace and in be enclosed within on the filter bores dividing plate (15) of Separation of Solid and Liquid chamber (5), can continue to pour into changing food waste again, according to said method circularly the operation;

In water-oil separating chamber (1), " waste oil " in the liquid is because density is littler than water, the not intersolubility layering of oil and water; Along with meal kitchen swill constantly joins in the water-oil separating chamber (1), " waste oil " in the water-oil separating chamber (1) constantly increases, the oil-water interfaces line constantly moves down, cause the oil-water interfaces line in the housing (11) progressively to shift to the B line downwards from the A line, and air pump (19) sends into air for aerator (111), make aerator (111) produce numerous fine bubble bubble, it is the air supporting effect, make " waste oil " float to the interior liquid level upper strata (A line) of housing (11) all the time, and big " water " of density is in the following and separated of " oil phase " all the time and opens, and constantly is discharged to purification of waste water by overflow pipe (20) with water after " waste oil " separates and handles in (2); In changing food waste constantly is added to Separation of Solid and Liquid chamber (5), when the liquid level that causes entering the liquid (" waste oil " and waste water) in the water-oil separating chamber (1) rises to liquid level ceiling for accumulation (A line), when continuing the liquid of interpolation again, the water that is separated will be discharged to through the overfall (118) of overflow pipe (20) in the purification of waste water chamber (2); During beginning, the liquid in the housing (11) mainly is kitchen waste water, and the probe (16) of the sensor of the oil water interface detector (18) of housing (11) middle and lower part is in the high aqueous phase of electrical conductivity, or oil pump (116) is in closed condition; Along with meal kitchen liquid (" waste oil " and waste water) constantly joins in the water-oil separating chamber (2), the amount of " waste oil " constantly increases in the housing (11), cause " waste oil " and the oil-water interfaces line of water progressively to be moved down into the B line position from the A line, that is, the volume area scope between A line and the B line all is " waste oil "; When the probe (16) of sensor when touching the low oil phase of " oil---water " parting line (B line) or electrical conductivity, induced signal is sent to controller (17), controller (17) starting program, and oil-feed pump (116) sends power supply or starts the operational order of pump; After oil pump (116) is connected power initiation, A line in the housing (11) and " waste oil " liquid between the B line are transported in " waste oil " buffer memory chamber (4) by oil pump (116) and carry out the buffer memory deposit, along with " waste oil " constantly is drawn out of, the oil-water interfaces line constantly down moves to the B line from the A line, when " oil--water " section line arrives the B line, when oil pump (116) is taken out probe (16) less than the sensor of " waste oil " or oil water interface detector (18) and is in the high aqueous phase of electrical conductivity, oil water interface detector (18) sends to controller (17) with induced signal, controller (17) starting program, and oil-feed pump (116) sends outage or the operational order of termination of pumping, and oil pump (116) stops to carry " waste oil ";

Also can show by the liquid level of " waste oil " in the liquid level gauge (118) of observing housing (11) side, manually use oil pump (116) that " waste oil " in the housing (11) is retracted in " waste oil " buffer memory chamber (4); In the above-mentioned oil water separation process, automatically control by the heating of the liquid in electric heater (112), temperature sensor (12) and temperature controller (119) the oil supply water separation chamber (1) and temperature, the control fluid temperature is 20-35 ℃ of scope, to accelerate oil-water separation;

Constantly the waste water that will flow into purification of waste water chamber (2) from the liquid overflow pipe (20) of water-oil separating chamber (1) carries out the purification processing up to standard of waste water in purification of waste water chamber (2), and aerobic biochemical technology routinely (MBR technology) carries out purification of waste water to be handled; Namely, will be under the air supporting effect of aerator (26), aerobic bacteria (as activated sludge) in the housing (27) fully contacts, digests and degrade with waste water, utilize water pump (23) and MBR membrane module (25) that the water in the housing (27) is extracted out by the filtration of MBR film, and be transported in the sterilization pond (3); Adopt liquid level sensor (22), fluid level controller (21) and water pump (23), liquid in purification of waste water chamber (2) is controlled high liquid level (HLL) line--C line and control minimum level line----D line, namely, when metal line arrives the C line, water pump (23) begins to start, and water is retracted in the sterilization pond (3), and liquid level begins constantly to descend, when metal line dropped to the D line, water pump (23) outage automatically cut out or termination of pumping;

In sterilization pond (3), the ozone that utilizes ozonization generator (36) to produce carries out disinfection or sterilizes the water in the sterilization pond (3), makes water quality reach " GB18918-2002 " urban wastewater treatment firm emission standards; Constantly the water up to standard that will sterilize in the pond (3) of water pump (35) is discharged; Adopt liquid level sensor (33), fluid level controller (32) and water pump (35), to the control in the sterilization pool (3) high liquid level (HLL) line--E line and control minimum level line----F line, namely, when metal line arrives the E line, water pump (35) begins to start discharges water, liquid level begins constantly to descend, and when metal line dropped to the F line, water pump (35) outage automatically cut out or termination of pumping;

Charging aperture (41) in " waste oil " buffer memory chamber (4), constantly accept " waste oil " that transport from the oil pump (116) of oil water separator (1), in order to prevent that " waste oil " solidifies because of low temperature, adopt electric heater (48) to heat for " waste oil " in " waste oil " buffer memory chamber (4), keep the flowability of " waste oil "; Automatically control more than 10 ℃ for " waste oil " heating and temperature in " waste oil " buffer memory chamber (4) by electric heater (48), temperature sensor (49) and temperature controller (50), or in case " waste oil " solidify.
