4. when the first ultrasonic level gage 13 indication is during without the position consistency of the water level in profit pond 1 and the water shoot 7 following 50mm of oil slick settling pit, the first magnetic valve 11 (being connected by control circuit) is opened in central control unit (pre-entering the computer of programmed) indication between the two, sewage after oil removing sand setting pumps into lower road sewage disposal operation through drinking-water pipe 10, when the first ultrasonic level gage 13 indication is without the water level in profit pond 1 during the position at above 50mm at the bottom of pond, the first magnetic valve 11 is closed in central control unit (pre-entering the computer of programmed) indication;
5. when the liquid level of the 4th ultrasonic level gage 25 indication oil slick reception tanks 9 arrives the position apart from oil slick district bottom 100mm, central control unit (pre-entering the computer of programmed) indication is opened the 5th magnetic valve 27 (being connected by control circuit) oil slick between the two and is pumped into waste oil collecting barrel through oil pick-up tube 26 and under meter 29, simultaneously under meter by the waste oil quantity that enters waste oil collecting barrel by wireless network transmissions to Surveillance center, Surveillance center just can promptly and accurately grasp the quantity that waste oil produces like this, so that allotment in time.If this application of installation, in diet places such as Large-scale Hotel, restaurants, can be carried out to Long-distance Control and management to the kitchen waste oil of its generation, and then controls the raw material of sewer oil from source, guarantee that common people are able to eat relieved oil.When position at above 50mm at the bottom of pond of the liquid level of the 4th ultrasonic level gage 25 indication oil slick reception tanks 9, the 5th magnetic valve 27 is closed in central control unit (pre-entering the computer of programmed) indication;
6. sealing cover 28 is for preventing that waste oil from arranging without under meter is removed, and its effect is to guarantee that this installs collected waste oil and all by Surveillance center, is monitored;
7. for preventing that indicator dog 18 from departing from the second ultrasonic material level meter 19 in floating, an indicator dog position-limited rack 17 that is fixed on pool wall is set especially, this position-limited rack 17 not only can guarantee that 18 of indicator dogs fluctuate under the second ultrasonic material level meter 19 and not depart from the second ultrasonic material level meter 19, can also be in liquid level during lower than lower end, oil slick district, the crossbeam of indicator dog position-limited rack 17 lower ends is to 18 1 supporting roles of indicator dog, to guarantee that it is suspended from oil slick settling pit top, the height of indicator dog is with regard to unnecessary do too high like this, be its thickness that is highly a bit larger tham oil slick district,
8. for anti-water-stop body fouls, without profit pond and oil slick settling pit, establishing respectively small underwater aeration head 2, summer every central control unit (pre-entering the computer of programmed) on the three indication without the aeration head aeration 5～10min in profit pond and oil slick settling pit;
In addition, in order to increase the collision between liquid particle, some groups of ejectors 15 facing each other have been installed at the middle part of oil removing settling pit especially, ejector 15 laterally between two in opposite directions jet the waste water at oil removing settling pit middle part is flowed (also comprising that other is difficult to the simple complex flow of describing) relatively, increased the collision opportunity between liquid particle, thereby created for making most of dispersed oil and the more short grained oil in water emulsion of part the chance that is more combined into the elaioleucite of larger particles, then these elaioleucites float to the top of liquid level naturally, thereby improve oil removal efficiency 3% left and right, the more important thing is that this part oil of removing is dispersed oil and oil in water emulsion more, conventionally they are difficult to remove, when entering next procedure, bring a very large difficult problem (no matter because be that dispersed oil or oil in water emulsion are all the organism of hard degradation can to operation below, they are difficult to biological degradation).
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
