Description

FIELD OF THE INVENTION [0001] The present invention relates to a grease trap,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a purifier, and more particularly, to a purifier for collecting sewage collected in a grease trap for collecting odd water generated after cooking or washing dishes in a kitchen of a large- The present invention relates to a grease trap sewage purifying apparatus for purifying organic waste matter such as milk fat, waste paper and sludge contained in wastewater by centrifugal separation and radical reaction through a photocatalyst, and discharging the grease trap to clean purified water.

Generally, grease traps installed in large foodservice facilities such as schools and companies are designed to allow sewage to stay for a while so that grease is not discharged during drainage.

Since sewage discharged mainly from restaurants contains a large amount of oil, if it is discharged as it is, it causes serious water pollution.

Especially, as the sewage is regulated legally, the grease trap is also obligatory in general restaurants.

Generally, grease traps are made up of a plurality of blocks, in which wastewater flows sequentially through these blocks and is configured to filter dirt and oil particles having a relatively large particle size by a filter net or various structures.

However, as described above, oil fractions filtered by the grease trap have an unsanitary problem such as a bad odor, and there has been a problem that a great cost is incurred for treating such oil.

Further, as described above, there has been a very troublesome problem in that, in order to process the oil at a large cost,

In order to solve such a problem, "Grip Strap and Grip Strap Cleaning Apparatus" registered as Korean Patent Registration No. 0687698 on Feb. 22, 2007 has been disclosed.

A first stepping net is installed on the inner wall of the housing to form an inlet port and an outlet port and to remove debris of the wastewater flowing into the housing buried in the basement and to discharge the wastewater flowing into the first stepping network through the outlet port And a first drainage collection plate is installed so as to be positioned below the outlet.

Further, only the wastewater, which is provided on the bottom surface of the housing and is suspended by the specific gravity, is pumped to the first drainage collection plate through the sewage pump.

However, although the water and the fat can be separated substantially by the specific gravity difference, the oil separated by the pumping power of the sewage pump is pumped at the same time, causing a serious problem that dirty domestic wastewater flows out to the sewer.

In addition, even if water and a fat are separated, there is a problem that the odor and bacteria leak out from the water and become a fundamental cause of environmental pollution.

It is an object of the present invention to provide a grease trap purifying apparatus for purifying grease trap by sucking various kinds of wastes including food waste scattered in a grease trap, .
