Abstract:
PURPOSE: A bad odor removing device due to physical collection in a rain gutter and a sewerage manhole is provided to construct pleasant environment by removing the discharge of bad odor and removing displeasure due to the bad odor. CONSTITUTION: A bad odor removing device due to physical collection in a rain gutter and a sewerage manhole comprises a bad odor blocking member(200), a magnetism member(310), a one direction rotating member(320), and a suction member(330). The bad odor blocking member is installed in a connection unit inlet(121) connected to a drain pipe(120). The half of the upper part of the bad odor blocking member is formed as a fixing unit, and the half of the lower part is formed as a rotating unit capable of rotating in a swage flow direction. The magnetism member is installed on a bottom unit of the connection unit inlet. When the flow rate of rainwater or the sewage is small, the suction member is attached to the magnetism member in order to suppress the discharge of the bad odor.

Abstract:
PURPOSE: A bad odor disposal device of a river box section of sewerage and bad odor disposal method are provided to include a contamination purification effect of a river and to suppress the discharge of bad odor. CONSTITUTION: A bad odor disposal device of a river box section of sewerage comprises a river box(100) and an air injection device. The air injection device comprises a blower(210), a guide pipe(220), an air injection unit(230), an air purification device(300), and a discharge unit(400). The blower sucks gas in the river box. The guide pipe guides the sucked gas to the bottom surface of the river box. The air injection device supplies the guided gas to the inside of the river box. The air purification device purifies the gas supplied from the blower. The purified air is discharged in the air by the discharge unit.

본 발명은 하수도 설비의 하수관거 등에서 발생하는 악취발생원에 따른 악취발생량을 하수도 GIS(하수도관리대장 지리정보시스템)과 연계하여 생성한 악취지도를 활용하여 악취저감 시설의 설치 비율을 예측함으로써 경제성·효율성을 분석할 수 있고, 나아가 악취를 미연에 방지하고 쾌적한 도시환경을 조성하며 악취로 인한 주민의 불편을 해소할 수 있는 악취발생량 예측을 통한 악취지도를 활용한 하수도 설비의 경제성·효율성 분석 방법을 제공하는데 그 목적이 있다. 상기 목적을 달성하기 위한 본 발명은, 악취발생량 예측을 통해 악취지도를 작성하고, 이 악취지도를 활용하여 하수도 설비의 경제성·효율성을 분석하는 방법으로서, 적용대상지를 구획하여 단지를 구분하는 단지 구분 단계; 상기 적용대상지 내의 정화조의 악취발생량을 산정하는 정화조 악취발생량 산정 단계; 상기 적용대상지의 하수관내 퇴적물에서 발생하는 악취발생량을 산정하는 관내퇴적물 악취발생량 산정 단계; 상기 적용대상지의 하수관의 관벽 생물막에서 발생하는 악취발생량을 산정하는 관벽생물막 악취발생량 산정 단계; 및 상기 악취발생량 산정 단계들에서 산정된 악취발생량을 분석하고 평가하는 분석 및 평가 단계를 포함하는 악취발생량 예측을 통한 악취지도를 활용한 하수도 설비의 경제성·효율성 분석 방법을 제공한다.
Abstract:
The present invention relates to a bad smell reduction apparatus and a bad smell reduction method in a bad smell generating area of a sewage facility, and more specifically, to a bad smell reduction apparatus and a bad smell reduction method which reduce bad smells in a reliable manner by using an iron salt filter capable of removing a main causative material of bad odors generated in a bad smell generating area; are capable of recycling removal media; facilitate maintenance as the iron salt filter is able to link to underwater SOB media; and minimize the electricity rate. In order to achieve the purpose, the present invention provides a bad smell reduction apparatus in a bad smell generating area of a sewage facility, comprising: a bad smell gas treatment bath; an air injection apparatus installed to inject air from the bottom of the water in the bad smell generating area; a bad smell gas reduction unit installed in the bad smell gas treatment bath and reacting with hydrogen sulfide to reduce bad smells; and an iron salt filter including a gas supply/discharge line for guiding bad smell gas in the bad smell gas generating area to the bad smell gas reduction unit, and discharging the deodorized gas.
