Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1, a kind of catering oily wastewater refining plant comprises sewage inlet and sewage outlet on casing 10 and the casing; Be divided into A, B, C, four separations of D in the casing 10, separate relatively between the separation, the bottom of A, B separation communicates; The top of A, B, C separation communicates; A riser, C thrust-augmenting nozzle 5 UNICOMs in riser and the C cabin have been opened in sealing around the dividing plate of C, D separation and the casing outside plate in the middle of C, the D separation; C thrust-augmenting nozzle 5 leads to C bilge portion, force oily(waste)water by the position of thrust-augmenting nozzle 5 to next separation D diffluence; Riser leads to place, D cabin a sealed cabin 7 is installed, and back-purge system 6 and polypropylene fibre filtering net 8 are housed in the sealed cabin 7, and oily(waste)water flows into the D chamber through polypropylene fibre filtering net 8 after coarse is handled;
As shown in Figure 1; In the bottom in A cabin aeration plate 1 is installed respectively in the casing 10; The bottom in D cabin also is equipped with aeration plate 11; Casing 10 outer active oxygen generator 13 and the high pressure positive blowers 14 of being provided with, active oxygen generator utilizes wavelength to send into the intravital aeration plate aeration of case for the active oxygen that the ultraviolet source between the 184.9-253.7nm produces through high pressure positive blower 14.
As shown in Figure 1, be provided with an A thrust-augmenting nozzle 2 in the said A cabin, A thrust-augmenting nozzle 2 one ends stretch out sewage inlet, and the other end extends to A bilge portion, forces oily(waste)water to enter into A bilge portion from the A thrust-augmenting nozzle, makes sewage pass through the aeration plate aeration; Be provided with a D thrust-augmenting nozzle 9 in the described D cabin, D thrust-augmenting nozzle 9 one ends stretch out sewage outlet, and the other end leads to D bilge portion, force sewage from the water inlet D of D bilge portion thrust-augmenting nozzle, make sewage accept active oxygen aeration for the second time.
Casing 10 bottoms are inclined-planes, and sedimentary dirt flows to the bottom on inclined-plane, open wash water valve 12, can be clean emissions, and if needed, bottom half can be installed flushing arrangement, is beneficial to blowdown.A, B, gathering room top, C separation top have oil discharge outlet 4, are convenient to the greasy dirt of assembling, floating is discharged.
The manageable waste water of the utility model is like the processing of the oil removal treatment of oily water treatment in kitchen oily(waste)water, community life sewage, service station, the Automobile Service Factory, machinofacture waste water, industrial production such as Steel Mill's emulsion oily(waste)water.
The sewage water treatment method of the utility model is to realize through following step:
(1) catering oily wastewater flow to the oily(waste)water ingress behind the elimination food garbage excessively through being connected in the pipeline of kitchen waste water, gets into casing A cabin and carries out water treatment.
(2) the abundant contact reacts of a large amount of high solubility oily(waste)waters in active oxygen aeration through being installed on A, B bilge portion and the A cabin makes that greasy dirt is assembled, come-up, and floats on A, B, top, C cabin, under the continuous action of active oxygen, and the oxidized degraded of sump oil.And that the sump oil that floats on the water surface becomes after oxidative degradation is cotton-shaped, softness.Form tabular lump easily unlike conventional oil trap top buoyant sump oil.And float on the sump oil at A, B, top, C cabin this moment is to be easy to through the sump oil TFL sump oil introduced the sump oil storage barrel.In case temperature is low excessively oil slick is condensed, can start the electric heater unit in oil slick district, make the dissolving of agglomerative oil slick.Electric heater unit is thermostatically controlled.
(3) liquid level along with oily(waste)water constantly rises, and oily(waste)water gets into the B cabin through the space of A, B separation bottom, and owing to aeration is carried out in A, B cabin simultaneously, sump oil gets into the B cabin through the space, bottom in the effect lower section of air thrust, makes sump oil float on the water surface.
(4) when sewage level surpasses the height of B, C cabin dividing plate, sewage gets into the C cabin, and the C cabin is a static relatively cabin, does not have the shock effect of aeration gas flow, and sump oil floats on the water surface in A, B, C cabin.
Again along with the injection of oily(waste)water; The sewage in C cabin is through being installed on the C thrust-augmenting nozzle between C, D separation; Flow into the combined labyrinth and carbon gland cabin in D cabin, handle through coarse material polypropylene fibre again, in the sewage oil droplet of a little through polypropylene fibre the time by coarse after cohesion rise and filter.
(5) the sewage naked eyes that get into the D cabin can not be seen the buoyant grease; In the D cabin; Sewage is accepted active oxygen aeration for the second time; Making remaining sump oil and organic matter degradation is that CO2+H2O. reduces phosphorus, nitrogen, SS, COD, the BOD in the sewage simultaneously, regulates pH value to normal range, and the sewage after the processing satisfies national urban sewage discharge grade III Standard.
(6) place the back-purge system in the box-like sealed cabin of D cabin upper group regularly coarse material polypropylene fibre to be carried out back flushing, remove the impurity such as sump oil of surface aggregation, guarantee the unobstructed of coarse material.
