Abstract

The present invention relates to a device for efficiently removing oil, and more particularly, to filter sludge from the collection tank of sludge and sewage, including food waste containing a large amount of oil components introduced through the sewage inlet. The sewage flows into the first chamber, and the oil from the sludge separated primary treatment water floats on the water. It is discharged to the outside after being flowed into the second chamber and the discharge tank step by the drainage pipe, and the floating oil near the surface of the oil that contains a lot of oil component in the primary treated water and the secondary treated water increases the suction force of the air. It is used to enter the oil suction pipe and send to the oil removal microorganism storage tank, and even in the oil removal microorganism storage tank, )) Is sent back to the first chamber through the circulation drain pipe connected to the first chamber in the lower part to be separated again, so that only oil components are collected in the oil removal microorganism storage tank to be decomposed and removed by microorganisms. Aeration in the first and second chambers and the oil removal microorganism storage tank increases dissolved oxygen, and the defoaming device recirculates the water of the discharge tank in the first and second chambers, and sprinkles it again. Since the oil in the upper part of the second chamber is transferred to the oil removal microorganism storage tank through the suction suction pipe, most of the oil in the first chamber and the second chamber is transferred to the oil removal microorganism storage tank in the process of repeating this process. Since microorganisms are also circulated in this process, the microorganisms are spread throughout the oil removal apparatus, and the microorganisms efficiently disassemble and remove oil components.

Description

High efficiency oil remover

The present invention filters the sewage of sewage, which is discharged from homes and restaurants, especially group meal facilities or restaurants, and contains a large amount of greasy and food waste by physical devices. The present invention relates to a high-efficiency oil removal device for decomposing and removing oil to send sewage without oil to a septic tank.

Household sewage discharged from group meal facilities or restaurants contains a large amount of sludge and food wastes containing oil components, so the pipes of facilities are clogged or bad odors are generated. ,

Conventional tools used were physical devices such as gristlabs, but the standard was not uniform, and in group meal facilities that temporarily discharge a large amount of sewage, these devices tend to overflow, making it difficult to obtain the effects and collecting them secondarily. There was a problem that it was expensive and difficult to collect.

The present invention is to solve such a problem, the management cost is low, and it is easy to recover the sludge such as food waste by the basket-type collection in the device, while decomposing and removing a large amount of oil components by microorganisms. It is an object of the present invention to provide a high-efficiency oil removing device for preventing the purification function from falling sharply when oil is introduced into the septic tank.

In order to achieve this purpose, the present invention separates sludge, such as food waste, from the collection bin and flows it into the first chamber.In the first treatment water from which the sludge is separated, the oil-rich oil water stays on the water surface and the oil-water oil water is lower It enters the second room through the 'H' drainage pipe with the entrance and exit to the second room. In the second room, the oil stays on the surface, and only the lower treated water with less oil content flows into the discharge tank through the 'H' drainage pipe. After being discharged to the outside through the outflow pipe, trapped floating oil near the surface of the surface containing a lot of oil in the primary and secondary treatment water is used as a funnel-shaped oil suction tube using the suction force of air. It enters into the oil removal microorganism storage tank, and the oil level of the oil removal microorganism storage tank is raised. Even in the tank, light oil is present on the water, and the treated water in the lower part is sent back to the first room through the circulation drain pipe connected to the first room to be separated again, so that only the oil is decomposed and removed by microorganisms. Aeration in the first and second chambers and oil removal microorganism storage tanks during the period of no inflow increases the dissolved oxygen to activate microorganisms, and by re-spraying the water in the discharge chambers in the first and second chambers with a defoaming device. As the water level in Room 1 and Room 2 rises, the residual amount of oil in the surface area is transferred back to the oil removal microorganism storage tank through the oil suction pipe, and the sewage of Room 1 is transferred to the 'H' drainage pipe by the pressure difference. As it flows into the discharge tank in stages, most of the oil in the first chamber and the second chamber is removed, and the oil component is decomposed by the microorganisms manually added to the oil removal microorganism storage tank. The microorganisms are spread throughout the apparatus to decompose and remove oil, and the next day, the oil is decomposed and removed.
