Abstract:
PURPOSE: A system for evaluating ecological construction value using a geographical information system and a method using the same are provided to perform accurate ecology construction value evaluation by an ecological construction value prediction processor and a geographical information processor. CONSTITUTION: An ecology construction value prediction process part(30) evaluates the ecology construction value by the multiple criterion decision making method based on the data inputted to the database unit(20). A geographic information processing unit(10) expresses the evaluated result in the geographical information system. An input-output unit(40) inputs the information from the ecology construction value prediction process unit and geographic information processing unit. The input-output part indicates results of being calculated by the ecology construction value prediction process unit and the geographic information processing unit.
Abstract:
The present invention has the purpose of providing an odor reduction apparatus and an odor reduction method, which basically supply air; oxidize hydrogen sulfide, which is a main cause material of odor, in the air of an odor generating area; and at the same time, oxidize odor substances selectively under water, so as to reduce the odor in a reliable manner; block odor generated in a sewage facility; and facilitate maintenance due to recyclable removal media. In order to achieve the purpose, the present invention provides an odor reduction apparatus in the odor generating area of a sewage facility, which comprises: an air injection apparatus installed to inject air from the bottom of the water in the odor generating area; and an odor gas reduction unit for oxidizing hydrogen sulfide generated in the odor generating area.

치어 복원용 침수형 인공섬은 중공이 형성된 상판과, 연결부재에 의해 상판과 연결되는 하판과, 연결부재에 의해 상판과 하판 사이에 연결되는 삽입판과, 연결부재의 상단에 연결되는 부유부재와, 연결부재의 하단에 연결되는 하중부재를 포함하고, 상판, 삽입판, 및 하판 사이의 간격은 치어들이 이동할 수 있는 높이로 형성된다. 이와 같이 구성되는 치어 복원용 침수형 인공섬에 의하면, 담수 생태에서 전이대 공간 확보로서 생물 서식처 확보를 통한 수생태 건강성을 회복하고, 치어를 중심으로 한 생태복원으로 근본적인 복원이 가능하며, 진광대층을 활용함으로써 먹이사슬 조성을 촉진할 수 있고, 바이오필름 조성으로 인한 치어 먹이 공급과 수질정화능력을 향상시킬 수 있는 이점이 있다.
Abstract:
PURPOSE: A manufacturing method of nitrate for deodorization using shells is provided to present an effective treatment by reusing the disposed oyster shell at the seashore. CONSTITUTION: The manufacturing method of nitrate using shells is to remove bad smell of the sewer pipe. The manufacturing method of nitrate using shells comprises preconditioning progress which removes impurity by washing the shell and processing plasticity with the shell; a generating process of nitrate aqueous solution that reacts the shell which removed the impurity by the preconditioning progress; a generating progress of nitrate crystalline powder which collects nitrate crystalline powder by cooling after concentrating the nitrate aqueous solution.
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.
