Description

Oil decomposing grease trap < RTI ID = 0.0 >

More particularly, the present invention relates to a grease separating apparatus and a grease separating apparatus which are configured to remove a waste disposal room while aerating an animal waste disposal room or a vegetation waste disposal room contained in a wastewater, To a storage decomposition grease strap capable of preventing contamination.

Recently, the intake of meat foods has been increasing with the change of preference of people in Korea.

As a result, the amount of fat used in hotels, department stores, fast food restaurants, supermarkets, restaurant kitchens, fisheries, meat corners, convenience stores, food factories that cook and produce meat products, gas stations, ships, The amount of waste water is increasing, but it is generally discharged in a mixed sewage system without a separate process for removing and treating it.

The discharged waste oil adheres to the surface of the sewer pipe and grows as it forms an oil film, thereby obstructing the sewer pipe, thereby reducing the amount of sewage transported and increasing the water pressure in the pipe.

In addition, the waste oil flowing into the sewage treatment plant forms an oil film on the surface of the water to inhibit the oxygen transfer of the sewage, and also forms an oil film on the surface of the treatment facility, resulting in a decrease in treatment efficiency.

The wastewater discharged from the pollution sources has a considerably high content of animal fats and has a limitation in the treatment by existing treatment facilities. In particular, since the quality of effluent water quality in the clean area is expected to be strengthened to less than 10 ppm BOD, it is urgently required to develop purification treatment technology of wastewater.

Taking this into consideration, a utility model registration application No. 20-2003-0034624 filed with the applicant has been filed for allowing the waste paper separated and floated on the inside of the strap to be adsorbed and recovered on the adsorbent in the sewage purifying trap.

However, such a conventional apparatus has a problem in recovery due to the solidification of the waste paper in the winter season, and inconvenient for the replacement of the adsorbent and the disposal of the adsorbent.

In addition, conventionally developed grease strains and bottom wastewater treatment machines are inconvenient to periodically introduce microorganisms or exchange adsorbents, and are expensive in the case of bilge pump for bottom wastewater. It has become a major cause of marine pollution by dumping the bottom wastewater into the sea in small and medium sized vessels.

Also, in large-scale foodservice facilities such as the present school, the operation regulations of the grip strap are erroneously executed, so that the function of the grip strap is forgotten and only the cleaning state is checked.

For example, in a school foodservice facility, there is no proper way to collect waste disposal rooms floating on the water surface inside the strap. Therefore, after removing the internal separation bulkheads and pit laps, In some gardens and large restaurants, all the waste paper is introduced into the septic tank because there is no grease strap that can even perform such functions, and the passage from the site of the waste disposal to the septic tank is blocked or piled up in the septic tank Since the function of the septic tank is lost, the septic tank installed for the treatment of sewage, sewage and wastewater is useless.

In addition, there has been a problem in that a large scale food poisoning incident occurs due to contamination of various kinds of water-borne infectious diseases through a conduit connected to the septic tank, thereby contaminating the cooking facilities.
