(Embodiment 1-2) The present invention relates to a device for removing foreign substances and oil from sewage, and in Embodiment 1-1, the housing 100 is disposed at an upper end of one side and has a hollow part communicating with the outside Formed in a structure, the inlet 110 receiving sewage from the outside; includes

(Example 1-3) The present invention relates to a device for removing foreign substances and oil from sewage. In Example 1-2, the housing 100 is disposed at the lower end of the other side and has a hollow part communicating with the outside. Formed in a structure, the outlet 120 for discharging moisture to the outside; includes

Sewage refers to household sewage, such as toilets, sinks, bathtubs and drains, as well as sewage and polluted rainwater used in factories, schools, and restaurants. Therefore, sewage treatment, which purifies sewage pollutants and discharges them into nature, is one of the processes that must be necessarily accompanied in order to protect water resources. In a facility that performs the sewage treatment process, sand and various wastes contained in sewage are physically removed, and aerobic microorganisms decompose and adsorb organic substances and pollutants included in the sewage to remove them.

As the above-described sewage treatment facility has limitations in the flow rate and efficiency of treating sewage, a filtration tank that removes foreign substances by itself before discharging the sewage to the septic tank is installed at the destination where the sewage is generated. However, as the general filtration tank installed at the drainage site is formed to filter only substances having a relatively large diameter from among foreign substances mixed in the sewage, a phenomenon in which oil remains in the sewage passing through the filtration tank may occur. can The remaining oil may adhere to the pipe forming the flow path between the filtration tank and the septic tank or act as a factor inducing overload of the sewage treatment facility.

In order to solve the above problems, the present invention is formed in a structure including the oil filtering unit 300 in the housing 100 in which a space recessed to a predetermined depth is formed therein. At this time, the housing 100 is formed in a structure including an inlet 110 of one upper end and an outlet 120 of the other lower end formed in the shape of a steel pipe having a hollow portion.
