Abstract

Various processing methods currently performed have problems such as lack of space, high cost, secondary disposal, and offensive odor. An object of the present invention is to solve these problems and to develop an apparatus capable of decomposing organic substances. The grease trap itself is used as a reaction tank by the reaction activity of the enzyme / medium in the reaction basket installed in the grease trap, and stirred by a non-blocking type submersible pump.
A heater is set on the suction side of the pump to adjust the temperature of the reaction liquid in the tank to the appropriate temperature for the reaction, and the mixture liquid created by the ejector connected to the discharge side is jetted to the reaction liquid to supply oxygen. In addition, by adjusting the hydrogen ion concentration (PH) by selecting the material of the medium in the reaction basket and adjusting the three conditions of water temperature, oxygen and PH of the reaction solution, the reaction rate (vigor) is increased to decompose oil and organic substances. By taking advantage of the suction action of the ejector, the odor problem was solved.

2. Description of the Related Art Conventional grease wrapping wastewater treatment methods include a method of periodically absorbing and cleaning with a vacuum car, a method of periodically introducing microorganisms for decomposition, and a method of removing fats and oils and scum on the water surface by a pump. Various methods such as suction, separation by an oil-water separator, and treatment are performed.
In any case, there are problems such as high cost, necessity of secondary cleaning, and generation of offensive odor during periodic processing.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the conventional grease trap, and can also eliminate organic substances other than oily substances, thereby saving space, labor, and cost. It is an object of the present invention to provide a disassembly processing device capable of realizing the conversion.

[0004]

SUMMARY OF THE INVENTION A grease trap tank 15 is provided.
The pump 1 is arranged in the water inside, the suction pipe 2 of the pump 1 is extended upward, and the tray 7 opened like a morning glory in the water near the water surface is set. A heater 10 controlled to keep the water temperature constant is penetratingly connected to the vertically rising suction pipe 2. The discharge pipe 3 of the pump 1 also extends vertically upward, connects the ejector 4 near the water surface of the tank 15, refracts it by 180 °, and drops as a jet pipe 5 to the bottom of the tank 15. The jet pipe 5 is horizontally branched in a T-shape near the bottom surface, and a bottom jet port 6 is opened at the tip of the jet pipe 5 to generate a mixed water flow which spreads in the tank 15. An intermediate portion of the jet pipe 5 is branched laterally to open an intermediate jet port 6. The intake port of the ejector 4 is opened on the water surface of the tank 15 to a space with the upper lid of the tank 15,
The air containing the offensive odor is sucked into the jet pipe 5, and the mixed water is jetted from the jet port 6. In a water-permeable and air-permeable reaction basket 11 mainly composed of a perforated plate or an unformed metal mesh, microorganisms for dissolving and eliminating organic substances and a microorganism carrier of a substance such as a porous natural stone suitable for supporting the microorganisms And placed in one corner of the water in the tank 15. Then, the intermediate jet port 6 of the jet pipe 5 is made to face the reaction basket 11, and mixed water is injected into the reaction basket 11, and the organic matter floating body is sent into the reaction basket 11 while supplementing oxygen, thereby decomposing by microorganisms. Prompt.

Embodiments of the present invention will be described with reference to the drawings. In the figure, solid arrows indicate water flows, and broken arrows indicate air flows. Grease trap tank 15
The reaction tank 11 is settled in one corner of the water inside. The pump 1 rotates, and the receiving tray 7 at the upper end of the suction pipe 2 collects oil and floating scum, and is sent to the discharge pipe 3 via the pump 1. In the discharge pipe 3, the stinking air on the water surface is sucked from the intake port 8 by the ejector 4, sent to the jet pipe 5 as mixed water, and injected from the middle and bottom jet ports 6. Then, stirring and oxygen supplementation are performed. At this time, the activity of the microorganisms in the reaction basket 11 spreads throughout the tank 15, and the tank 15 itself becomes a reaction tank. The heater 10 is controlled by the thermistor 9 to universally maintain the optimal temperature for microbial activity.
By selecting the microorganism carrier in the reaction basket 11, the hydrogen ion concentration of the water is adjusted, and in combination with the temperature and oxygen, the activity of decomposing organic substances by microorganisms is promoted. As a result, decomposition of the small-diameter garbage that has passed through the mesh of the garbage collection basket (not shown) provided at the inlet into the tank 15,
It can be extinguished, and the odor sucked from the intake port 8 is injected into the water and decomposes, and the bubbles ruptured on the water surface are absorbed again and returned to the water to be decomposed.
The odor problem is also solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A suction pipe 2 and a discharge pipe 3 of a corrosion-resistant submersible pump 1 are vertically piped, a saucer 7 is joined to the upper end of the suction pipe 2, and a heater 10 is set in the middle. The suction pipe 2 is moved up and down according to the depth of the water in the tank 15 so that the receiving tray 7 is located at an appropriate position below the water surface. A thermistor 9 is set horizontally and an ejector 4 is set downward in the bending portion of the discharge pipe 3. A jet pipe 5 is provided before (below) the ejector 4 and is divided into two in a T-shape near the bottom surface of the tank 15 in the left-right direction. The two branch pipes are bent at a predetermined position by 90 °, and the outlets 6 are respectively opened at the ends thereof. The mixed water jetted from the bottom jet port 6 causes a water flow circulating in the entire tank 15. Further, another jet tube is branched from the middle of the vertical portion of the jet tube 5, and the jet port 6 at the tip thereof is opposed to the reaction basket 11 fixed in the tank 15. The reaction basket 11 is provided with water permeability and air permeability using a punching plate or a wire mesh. The reaction basket 11 contains a microorganism carrier such as a porous natural stone. The capacity is adjusted according to the amount of water in the tank 15. Reaction basket 11
The method of setting is to hang the proper position of the lower surface of the upper pig as a fulcrum, or to fix it to the bottom of the tank 15 by a leg. In the drawings, reference numeral 12 denotes a drain plug, and reference numeral 13 denotes a cap tire.
