Description

  The present invention relates to a grease trap device for removing oily components from wastewater containing oily components, such as wastewater from restaurants and the like, and a supply mechanism for supplying oil adsorbing powder.

  Drainage from kitchens where food and beverages are cooked like restaurants (dining room drainage) usually contains cooking oil in addition to raw garbage, and can be used directly to sewers and rivers. If drainage is performed, the oily component may solidify and adhere to and accumulate in the drainage pipe and sewer pipe, which may cause clogging and contaminate the river. For this reason, the cafeteria drainage containing oily components has been once passed through a grease trap device provided under the floor of the kitchen, etc., and the oily components in the drainage are separated in the grease trap device and then discharged.

  The grease trap device basically stores the wastewater once, and periodically removes the oily component collected on the surface by machine or manual operation. However, the removal operation is troublesome and the oily component is removed. Adheres to the wall of the storage tank, and bad odor due to oxidation of the oily component becomes a problem. Therefore, various proposals have been made to treat oily components in a grease trap apparatus.

  For example, Patent Documents 1, 2, and 3 disclose means for disposing an oily component from a drainage by disposing an oily component adsorbent in a storage tank of a grease trap device and adsorbing the oily component to the adsorbent. ing. Patent Document 4 discloses means for removing oily components by using oil-degrading bacteria and performing biodegradation of oily components in a decomposition tank (storage treatment tank), and Patent Document 5 further discloses saponification. Means for adding an agent to waste water and soaping out oily components is disclosed.

  As described above, various means for removing oily components have been proposed, but since biodegradation of oily components requires a certain amount of time, a wastewater decomposition tank (storage tank) requires a large volume, In the case where a simple and small-capacity grease trap device such as a general canteen or restaurant is adopted, the decomposition treatment cannot catch up with the amount of waste water.

  Moreover, in the means which employs an adsorbent, as disclosed in the above-mentioned Patent Document 2, the oil-degrading bacterium is included in the adsorbent and the adsorbed oil is biodegraded. Takes time, and the amount of oily component adsorbed is limited until all of the adsorbed amount is decomposed, or the oily component not adsorbed on the adsorbent is discharged due to the placement of the adsorbent, etc. Certain oil removal is not done.

  In addition, soaping requires a saponification substance, and the direct outflow of soapy water into rivers and the like has a problem of affecting aquatic organisms and increases the treatment burden during sewage treatment.

  Furthermore, as means for supplying the treatment agent to the storage treatment tank, Patent Document 3 is a cloth cut article, and no special supply mechanism is disclosed. Patent Documents 4 and 5 do not describe the detailed structure, but are liquid supply devices from the configuration diagram.

The grease trap apparatus according to the first embodiment shown in FIG. 1 includes an oil adsorbing powder spraying mechanism 1 and a processing tank 2. The processing tank 2 includes a water inlet 3 and a stirring mechanism (aeration mechanism: fuming air). Part 21), a net container 4 for taking out a solid content separation function, and a water discharge part 5 are provided.

  The oil adsorbing powder spraying mechanism 1 is connected to a container-shaped powder storage unit 11, a quantitative supply unit 12 that operates by rotational driving at the bottom of the powder storage unit, and the quantitative supply unit 12, and also processes the front end port. It is comprised with the conveyance part 13 which faced the predetermined position of the tank.

  The powder storage unit 11 includes a cylindrical container body 111 and a lid body 112 having an appropriate capacity, and forms a discharge port 114 at a predetermined position (a position corresponding to a supply port 123 described later) on the bottom surface 113 of the container body 111. Further, a barrier 115 is provided in the vicinity of the discharge port 114.

  The quantitative supply unit 12 includes a rotating plate 121, a rotation driving unit (motor) 122, and a control unit (not shown) of the rotation driving unit, and the rotating plate 121 rotates on the inner bottom surface of the container body 111. In this way, the outer peripheral portion is formed in a step that is one step lower than the rotation center portion, and the supply port 123 is formed in the low step portion.

  The barrier 115 is provided immediately above the rotating plate 121 so as not to hinder the rotation of the rotating plate 121, and is particularly provided in a shape corresponding to the step and on the rotational direction side of the position of the discharge port 114. is there.

  The transport unit 13 includes a supply pipe 131 and a blower 132. The supply pipe 131 is connected to the discharge port 114, and a front end port 133 is disposed at a predetermined position (a net for taking out precipitates or the like) of the processing tank 2 described later. The horizontal pipe 134 is connected in the middle, and the horizontal pipe 134 is connected to the blower 132 so as to realize blown conveyance.

  The processing tank 2 is a tank body having a volume similar to that of a normal grease trap device, and aeration unit (stirring mechanism unit) 21 disposed on the bottom surface of the air pump 6 and the processing tank 2 performs air aeration to discharge waste water B in the processing tank. Is agitated.

  The water inlet 3 is the same as the previous device, and has a mesh bag body (contaminant remover) 32 detachably attached to the outlet of the water inlet pipe 31 of the canteen drainage A, and further holds the mesh bag body 32. A portion (perforated cylinder) 33 is disposed in the processing tank 2.

  The solid content separation function is realized by a net container 4 for taking out precipitates and the like, and the net container 4 for taking out is an appropriate net container body and is installed in the processing tank 2 so as to be removable. The position of the fusible portion 21 is avoided as much as possible.

  The drainage section 5 discharges the oil separation drainage C from which the solid (oil) has been removed from the tank drainage B in the treatment tank 2 to the outside, and is connected to the treatment tank 2 to the opening of the drain pipe 51. A suitable filter 52 is provided.

  The grease trap device having the above-described configuration is used while being drained from the kitchen (dining room drainage) A from the kitchen where food and drink are being cooked as in a restaurant, etc. Oil adsorbed powder in the container body 111 (commercially available one-component type oil treating agent, bioremediation accelerator with oil adsorbing ability: for example, granules of several tens of μm, dispersed when stirred in water, A trade name “Utras Ace α” (sold by Mitsubishi Gas Chemical Co., Ltd.) that adsorbs and precipitates oil is stored in the container body 111. The operation control of the rotation drive unit 122 is set in advance.

  Thus, the cafeteria drainage A flows into the treatment tank 2 from the water inlet pipe 31, and the contaminants in the cafeteria drainage A are removed by passing through the contaminant removal unit 32 during the inflow. This canal drainage A contains oily components in addition to contaminants, but the oily components are not removed by the contaminant removal unit 32 and are scattered in the wastewater stored in the treatment tank 2 (tank drainage B). Will do.

  Therefore, when the rotation driving unit 122 and the blower 132 are operated simultaneously, the rotating plate 121 rotates, and the oil adsorbed powder (powder) in the powder storage unit 11 at a place where the supply port 123 and the discharge port 114 of the rotating plate 121 overlap. a falls downward. In particular, the powder a carried in the rotation direction by the rotating plate 121 collides with the barrier 115, and the powder a is surely dropped.

  The fallen powder a is conveyed through the horizontal tube 134 by the air b, discharged from the front end port 133, and supplied and dispersed toward the extraction net container 4.

  The tank drainage B is stirred while being aerated by the operation of the air pump 6, so that the dispersed powder a is mixed with the tank drainage B to adsorb the oily component contained in the tank drainage B, The oily component separates from the turbid state and becomes a precipitate or suspended matter.

  In particular, since the supply and dispersion of the powder a is directed toward the extraction net container 4, the powder that has adsorbed oil mainly in the container 4 is deposited in the container 4 as a precipitate / floating matter (separated oily component) D. Will remain.

  The treated in-tank waste water B from which the oily component has been removed is discharged from the drain pipe 51 into sewage or the like. Further, the sediment / floating matter (separated oil component) D accumulated in the extraction net container 4 is taken out of the processing tank 2 and discarded.

  Therefore, for example, when the restaurant is opened and the operation switch of the oil adsorbing powder spraying mechanism 1 is turned on at that time, and the drive interval time of the rotating plate 121 and the blower 132 is set in advance, the amount of powder a supplied into the processing tank 2 is reduced. Since it can be determined, the optimum powder supply can be realized on the basis of the drainage amount of the canteen drainage A at the use location, the mixing ratio of oil, the capacity of the treatment tank 2, and the like.

  Moreover, you may employ | adopt another structure as shown in FIG. The oil adsorbing powder spreading mechanism 1a illustrated in FIG. 4 has a powder storage part 11a formed in a hopper shape, an opening 116 is provided on the inner bottom surface of the powder storage part 11a, and a quantitative supply part 12a is provided below the opening 116. They are connected.

  The fixed amount supply unit 12a is a so-called rotary valve, and incorporates a columnar valve body 125 that rotates in a cylindrical valve box 124, and has a housing recess 126 formed on the outer peripheral surface of the valve body 125. Is connected to the supply pipe 131. Other configurations are the same as those of the oil adsorbing powder spreading mechanism 1 of the first embodiment described above.

  In the oil adsorbing powder spreading mechanism 1a, when the valve body 125 is rotated 180 degrees, the powder a existing in the storage recess 126 falls into the supply pipe 131 and is blown by the blower 132 that is operated simultaneously. The inside is conveyed, discharged from the front end port 133, and supplied and dispersed toward a predetermined position of the processing tank 2.

  Therefore, a desired amount of powder can be dispersed by controlling the rotation of the valve body 125 based on the timely interval and the detection result of the water level sensor attached to the treatment tank 2. .

  FIG. 5 shows a second embodiment of the present invention. This embodiment employs a pumping mechanism 4a in order to realize reliable removal of the precipitate / float (separated oil component) D. It is what.

  The pumping mechanism 4a has a pumping port 41 in the vicinity of the bottom surface of the processing tank 2 or at an appropriate water level, and discharges air from the air pump 6 to a pumping pipe 43 provided with a discharge port 42 in the upper part of the processing tank 2. Thus, an air lift pump is configured, and a filter 44 and a filter tray 45 that can filter the sediment / floating matter D adsorbing oil to the discharge port 42 are provided.

  Moreover, the water discharge part 5a receives the waste_water | drain (processed waste_water | drain) C solid-liquid-separated by the filter 44, and the drain membrane 51 provided between the said water discharge pipe 51 and the processing tank 2 which discharges | emits out of the apparatus. 53.

  As in the first embodiment, the grease trap apparatus having the above-described configuration is provided while draining water (canteen drainage) A from a kitchen where food and drink are being cooked as in a restaurant, etc., as before. The canteen drainage A flows into the treatment tank 2 from the water inlet pipe 31 and passes through the mesh bag 32 during the inflow to remove impurities in the canteen drainage A.

  When the water level of the waste water B in the treatment tank reaches the treatment water level (high water level) H, the oil adsorbing powder spraying mechanism 1 is activated and a predetermined amount (amount corresponding to the volume of the treatment tank 2: treatment tank at the high water level H). The amount of oil adsorbed powder a) corresponding to the amount of internal wastewater is supplied and dispersed in the treatment tank 2.

  At the same time or earlier (accelerating the action of oil-degrading bacteria in the wastewater and suppressing the generation of malodor by aerobic fermentation of the wastewater B in the treatment tank), the air pump 6 is operated to aerate the wastewater B in the treatment tank. And stir. The oil adsorbed powder a sprayed on the waste water B in the treatment tank is stirred together with the waste water B in the treatment tank to adsorb the oily content contained in the waste water B in the treatment tank, and the oily content is separated from the turbid state in a lump state. Precipitate and float.

  Therefore, aeration and agitation are stopped, air is sent out from the air pump 6 into the pumping pipe 43, and the precipitate (separated oil component) D is pumped up on the filter 44 by the air lift action to perform solid-liquid separation.

  The separated solid content (separated oily content) D is accumulated in the filter 44, and the treated wastewater C from which the oily content has been removed is discharged from the outlet pipe 51 into sewage or the like. At the same time, the filtration membrane 53 prevents solids from passing, and only the treated waste water C that does not contain oily components passes through and is discharged from the drain pipe 51.

  Furthermore, the separated oily component D stored in the filter 44 is biodegraded simply by leaving it in the soil as it is, and returns naturally. In particular, since the oil adsorbed powder a is a bioremediation promoter, the above-described biodegradation is also effectively performed.

  FIG. 6 shows a third embodiment in which a receiving tank 7 is provided in addition to the processing tank 2 a and a water discharge part 5 a that does not include the permeable membrane 53 is adopted.

  The receiving tank 7 is connected to the water inlet pipe 71, further provided with a contaminant removing part 72 in the water inlet pipe 71, and provided with an aeration mechanism, and further provided with a sluice part 8 between the processing tank 2a. The sluice part 8 is configured to perform inflow control to the treatment tank according to the water level of the treatment tank 2a.

  The water discharge section 5a is configured such that the discharge port 42 of the pumping pipe 43 of the pumping mechanism 4a, the filter 44, and the filter tray 45 are disposed above, and the water discharge pipe 51 is provided continuously.

  Thus, the third embodiment also removes the oily content of the canteen drainage A in the same manner as the first embodiment, and the canteen drainage A flows into the receiving tank 7 from the inlet pipe 71. By passing through the foreign matter removing section (reticulated bag) 72, the foreign matter in the canteen drainage A is removed and temporarily stays in the receiving tank 7.

  In the treatment tank 2a, when the predetermined low water level L is reached, the sluice part 8 opens, and the contaminant removal waste water E in the receiving tank 7 flows into the treatment tank 2a.

  The sluice unit 8 is closed for a certain time or when a predetermined high water level H is reached, and in the treatment tank 2a, the oil adsorbing powder spraying mechanism 1 is activated to spray a predetermined amount of the oil adsorbing powder a, and at the same time agitated by aeration. Is done.

  Therefore, the waste water B in the treatment tank is separated from the turbid state by the sprayed oil adsorbing powder a, and settles and floats in a lump, so after aeration stirring is stopped, it is sent to the filter 44 through the pumping pipe 43. The treated waste water C that has been subjected to solid-liquid separation at 44 and from which oily components have been removed is discharged from the drain pipe 51 into sewage or the like.

  Therefore, since the third embodiment can be temporarily stored in the receiving tank 7 even if there is a change in the canteen drainage A, it is possible to efficiently disperse the oil adsorbed powder a and separate the precipitate in the processing tank 2a. Is something that can be done.

  The invention is not limited to the above-described embodiment, and the simplest configuration includes an oil adsorbing powder spraying mechanism 1 and a processing tank 2b as in the fourth embodiment illustrated in FIG. The tank 2b is connected to a water inlet 3 having a mesh bag body 32 for removing contaminants, provided with a stirring mechanism 22 and provided with a mesh partition 23 for performing a solid content separation function. It is only necessary to attach the water discharge part 5 to the downstream side of the part 23, and the sediment / floating matter adsorbing the oil may be appropriately pumped up or biodegraded.
