따라서, 본 고안은 이러한 국내의 방류수 처리 현황을 감안하여 안출된 것으로서 하수처리장의 폐수처리 방류수를 적절히 이용한 소수력의 발전구조를 제공하는 것이다.Therefore, the present invention has been devised in view of the present condition of domestic effluent treatment, and provides a power generation structure of hydrophobic power using wastewater treatment effluent in a sewage treatment plant.
종래에는 하수처리장의 폐수방류수를 재활용할 아무런 방안이 마련되어 있지 못하여 귀중한 자원이 그대로 유실되었음으로 이와 같은 폐수 및 하수 처리장에서 처리된 물을 다시 효율적으로 처리할 방안이 매우 절실하였다.In the related art, since there is no way to recycle the wastewater discharged from the sewage treatment plant, valuable resources are lost. Therefore, there is a great need for a method for efficiently treating the wastewater and the treated water in the sewage treatment plant again.
따라서, 상기의 제반 문제점을 해결하기 위해 안출된 본 고안은 유실되고 있는 에너지 자원을 적절하게 회수ㆍ재활용함으로서 자원의 재생효과의 더불어 부족한 전력의 수급에 기여하기 위함에 그 목적이 있다.Therefore, the present invention devised to solve the above problems has the purpose to contribute to the supply and demand of insufficient power as well as the regeneration effect of resources by appropriately recovering and recycling lost energy resources.
상기의 목적을 달성하기 위해 본 고안은 낙차 높이가 적어도 4m이상을 유지하면서 방류수가 안내되도록 하수처리장의 낙하지점에 설치된 경사진 연결수로와; 상기 연결수로의 내 공간부에 맞도록 외경의 크기가 설계되어 연결수로의 끝단부 지점에 설치된 채 방류수의 흐름에 의해 가동되도록 한 수력 터어빈; 및 상기 수력 터어빈의 가동에 따른 발전과 전력수급을 위해 마련되는 소정의 발전설비가 구비되어 이루어짐을 그 특징으로 한다.In order to achieve the above object, the present invention has an inclined connection channel installed at the drop point of the sewage treatment plant to guide the discharge water while maintaining the drop height at least 4 m; A hydraulic turbine designed to fit the inner space of the coupling channel and operated by the flow of discharged water while being installed at an end point of the coupling channel; And a predetermined power generation facility provided for power generation and power supply according to the operation of the hydraulic turbine.

이하, 본 고안의 바람직한 일실시예를 통해 그 양호한 재현성을 확인하여 볼 수 있다.Hereinafter, it can be seen to check the good reproducibility through a preferred embodiment of the present invention.
본 실시예에 따른 소수력 발전구조는 첨부된 도 1에서와 같이 통상의 하수처 리장 방류지점에서 낙차 높이가 적어도 4m이상을 유지하도록 하수처리장의 낙하지 점에 경사지게 연장된 연결수로(1)를 설치토록 하여 방류수가 통과되도록 하며, 이후 상기 연결수로(1)의 내 공간부에 맞도록 외경의 크기가 설계됨으로 상기 공간부에 밀착지게 연결수로(1)의 끝단부 지점에 설치되어진 동력발생수단의 수력 터어빈(2)이 상기 방류수에 의하여 가동되도록 하는데, 이때 상기 수력 터어빈(2)의 가동에 따른 발전과 전력 수급을 위해 소정의 발전설비가 외부로부터 제어되도록 마련되는 것이다.The hydrophobic power generation structure according to the present embodiment has a connection channel 1 which is inclined to the drop point of the sewage treatment plant so as to maintain the drop height at least 4 m at a conventional sewage treatment discharge point as shown in FIG. 1. It is installed to allow the discharge water to pass through, and since the size of the outer diameter is designed to fit in the inner space of the connection channel 1, the power installed in the end point of the connection channel 1 in close contact with the space The hydraulic turbine 2 of the generating means is operated by the discharged water, in which a predetermined power generation facility is provided to be controlled from the outside for power generation and power supply according to the operation of the hydraulic turbine 2.
상기의 구조적 특성에 의해 경사지게 연장된 연결수로(1)를 통해 낙하되는 방류수가 연결수로(1)의 내 공간부에서 수력 터어빈(2)을 강력 회전시키게 되고 이에 따라 소정의 전력수급을 위한 발전을 충분히 예견하여 볼 수 있는데, 이를 국내 경기도 안양의 하수처리장에 적용하여 본 결과 다음과 같은 결과치와 가능성이 입증되었다.Due to the above structural characteristics, the discharged water falling through the connection channel 1 extending inclined strongly rotates the hydraulic turbine 2 in the inner space of the connection channel 1, and accordingly, a predetermined power supply It is possible to anticipate the development sufficiently, and applying it to the sewage treatment plant in Anyang, Gyeonggi-do, Korea proved the following results and possibilities.

통상, 하수처리장에서 배출되는 방류수는 계획된 량과 일정조건이 충분하게 갖추어진 에너지 자원으로서 여름, 겨울, 갈수기 등에도 거의 일정한 방류량을 유지하여 본 고안을 적용할 경우 그 시설 효용성이 높고 방류량이 유지되는 한 거의 무한 기간동안 사용될 수 있다는 경제적 유용성을 갖는다.In general, the discharged water from the sewage treatment plant is an energy resource with sufficient planned quantity and certain conditions, and maintains a constant discharge amount even during summer, winter, and dry season, so that the utility of the present invention is high and the discharge rate is maintained. It has the economic utility of being able to be used for almost infinite time periods.
따라서, 본 고안은 연중 무휴로 폐수의 량이 일정하므로 시설용량에 맞는 발전설비만 구비하면 되는 것으로, 결국 본 고안의 하수처리장 폐수처리 방류수를 이용한 소수력발전은 댐 조성에 따른 공사비를 현저히 절약할 수 있음과 동시에 소정의 발전설비만 갖추면 됨으로 그 경제적인 파급효과가 매우 크게 된다.Therefore, the present invention is a year-round year-round waste water quantity is only required to be equipped with a power generation equipment according to the capacity of the facility, after all, the hydropower generation using wastewater treatment effluent in the sewage treatment plant of the present invention can significantly reduce the construction cost according to the dam composition At the same time, since only a predetermined power generation facility is provided, the economic ripple effect becomes very large.
또한, 본 고안의 수력 터어빈(2) 수치에 있어서 폐수처리 방류수가 B O D 20ppm 정도로만 방류되므로 저수댐에 의한 수력발전에 비하여 수차를 부식시킬 수는 있으나 조력발전의 경우보다는 훨씬 양호한 내구성을 유지할 수 있으므로 결국일반 스텐레스 스틸제의 수차로도 충분히 가능한 것이어서 그 실시적 가치가 매우 높다.In addition, in the hydro turbine (2) value of the present design, since the wastewater treatment effluent is discharged only about 20 ppm of BOD, it can corrode aberrations compared to hydropower generation by low-water dams, but it can maintain much better durability than tidal power generation. Since the aberration made of ordinary stainless steel is sufficiently possible, its practical value is very high.
