Abstract:
The present invention relates to a water treatment method using a water treatment apparatus having a four-staged removing equipment with at least one cyclone which enables final treated water to be discharged to upper parts wherein raw water including solids and floating materials is moved from the lower part of the equipment. The water treatment method of the present invention, by using micro nanobubbles and cyclone technology, not only treats waste water including solid with high precipitate, but has high efficiency in removing fine particles with high floating. Also, the method does not use chemicals like cohesive agents, thereby having no problems of secondary water pollution; and increases the preprocessing efficiency which increases ultrafiltration (UF) membrane processing and operation efficiency. Accordingly, the present invention is very useful for processing wastewater and re-use processing of wastewater discharge.

본 발명은 공업용수 및 음용수 공급장치에 관한 것으로, 보다 상세하게는, 외부에는 원수를 저장할 수 있는 원수저장탱크가 있고, 내부에는 상기 원수저장탱크에서 원수를 공급받아 정수처리하는 다수의 정수유닛과 상기 다수의 정수유닛에서 정수된 원수를 저장할 수 있는 다수의 수조가 구비된 정수시스템을 포함하는 공업용수 및 음용수 공급장치에 관한 것이다. 본 발명에 따른 공업용수 및 음용수 공급장치는 최초 공급되는 원수를 각각의 용도에 맞게 다양하게 정수하여 제공하므로 버려지는 배수가 없으므로 수자원 보호차원에서도 뛰어난 기여를 할 수 있고, 한 대의 수처리 장비에 의하여 각각의 용도에 맞는 다양한 수질의 정수가 가능하므로 경제적이라는 장점이 있으며, 용도에 맞게 다양한 수질로 처리된 정수가 각각의 수조에 저장됨에 따라 대용량으로 신속하게 공급될 수 있다는 효과가 있다.
Abstract:
An agricultural water treatment apparatus is provided to utilize the irrigation water or river water as clean agricultural water by removing suspended solids and microorganisms contained in irrigation water or river water, and a method for converting irrigation water or river water into agricultural reusing water using the apparatus is provided. An agricultural water treatment apparatus comprises: an inflow pump(7) for flowing agricultural water into the apparatus; a filter unit(20) for removing suspended solids contained in the agricultural water that has been flown in by the inflow pump; a storage tank(1) including a ultraviolet module(2) for sterilizing the agricultural water from which the suspended solids have been removed by the filter unit and a level switch(3) for sensing a level of agricultural water; a feed pump(12) connected to the storage tank to feed the agricultural water that has been treated in the storage tank to farmland; a cleaning valve(5) connected to the storage tank to supply the agricultural water that has been treated in the storage tank as cleaning water; a cleaning stand(6) for collecting the agricultural water that has been used as the cleaning water; a zero discharge tank(25) including a carbon filter(11) for removing alien substances from agricultural water that has been collected in the cleaning stand; a strainer(10) for filtering agricultural water that has been treated in the zero discharge tank to discharge the filtered agricultural water; and a control box(4) for controlling operations of the inflow pump, storage tank, feed pump, and zero discharge tank.
Abstract:
PURPOSE: An apparatus for generating ultrafine bubble water is provided to generate bubbles of micro-nano sizes in water based on various kinds of gas by using a simple structure. CONSTITUTION: An apparatus for generating ultrafine bubble water includes a liquid supplying part(21), a gas injecting part(22), a venturi injector(27), a compression rotating part(28), a spraying unit(29), and a controlling part. The liquid supplying part injects liquid into the apparatus. The gas injecting part injects gas into the liquid. The venturi injector pressurizes and emits gas containing liquid generated from the gas injecting part. The compression rotating part rotates and impacts the gas containing liquid to induce an afferent spiral motion. The spraying unit sprays the gas containing liquid through a porous plate to generating ultrafine bubble water.
Abstract:
A reservoir decision support system using a GIS and an operation method thereof are provided to rationally and promptly make a decision for developing, redeveloping, and reinforcing a reservoir by automatically selecting the new reservoir, and redevelopment priority and a scale of the reservoirs based on data stored in the GIS. A topology database(171) stores topology information. A property database(172) stores environmental/topological development constraint factors, development possibility factors, and common factors. A system operation unit(120) inputs a predetermined weight coefficient to the development constraint factors, the common factors, and the development possibility factors, and sums and outputs the factors in descending order. A GUI(Graphic User Interface)(130) outputs a calculation result and geographic information at the same time. A CPU(110) controls each component.
