Description

호소정화공법{LAKE PURIFICATION METHOD}LAKE PURIFICATION METHOD}

본 발명은, 호소정화공법에 관한 것으로서, 보다 상세하게는, 호소의 바닥층의 혐기화를 억제시킬 수 있으며 호소수중의 질소를 효과적으로 제거할 수 있도록 한 호소정화공법에 관한 것이다.TECHNICAL FIELD The present invention relates to a method of purifying a lake, and more particularly, to a method of purifying a lake which can suppress the anaerobicization of the bottom layer of a lake and effectively remove nitrogen in the lake water.

호소(Lake)는, 일정한 공간내에 유입된 물이 소정 기간 동안 체류하게 되는 수계시스템을 지칭하는 것으로, 호수, 늪, 소택(沼澤), 습원(濕原)으로 분류된다.Lake refers to an aquatic system in which water introduced into a certain space stays for a predetermined period of time, and is classified into a lake, a swamp, a marsh, and a wetland.

최근에는 생활하수, 초기 우수, 축산폐수 등이 호소로 유입되어 호소가 오염되는 것을 방지할 수 있도록 차집관거를 마련하여 유입수를 하수종말처리장으로 차집하도록 하고 있다.In recent years, sewers have been set up to prevent sewage from being polluted by the inflow of municipal sewage, early stormwater, and livestock wastewater to the lakes, so that the inflows are collected to sewage treatment plants.

한편, 차집관거 등에 기인하여 호소로의 유입 및 유출이 지속적으로 이루어지지 아니하게 되면 호소수는 쉽게 정체되고 유기물질의 퇴적이 진행된다. 더욱이 이미 호소로 유입된 오염물질이 정화되지 아니 한 경우, 바닥층의 혐기화가 촉진되어 금속물질과 화학적 결합되어 있는 인산염이 용출됨으로써 수계의 인성분의 농도는 더욱 높아지게 되어 조류의 발생 및 증식을 촉진시키게 된다. 이에 따라 호소수는 부패하게 되고 탁도가 흐려지고 악취를 유발하게 되어 수계주변의 위생환경을 악화시키게 된다.On the other hand, if the inflow and outflow to the appeal is not made continuously due to the conduit, etc., the appeal water is easily stagnated and the deposition of organic materials proceeds. Furthermore, if the contaminants that have already entered the appeal have not been purified, the anaerobicization of the bottom layer is promoted and the phosphate, which is chemically bound to the metals, is eluted, resulting in higher concentrations of phosphorus in the water system, which promotes the development and growth of algae. do. As a result, the appealing water becomes corrupt, the turbidity is clouded, and the odor is induced, thereby deteriorating the sanitary environment around the water system.

호소의 부영양화를 진행시키는 대표적인 요소로는 질소성분 및 인성분이 있다. 일반적으로 질소성분은 유기질소태 및 무기질소태의 형태로 존재하며, 수중에존재하는 무기질소태는 질산염태보다는 암모니아태의 형태로 존재하게 된다.Representative elements of advancing eutrophication of the lake include nitrogen and phosphorus. In general, the nitrogen component is present in the form of organic nitrogen and inorganic form, the inorganic form present in water is present in the form of ammonia rather than nitrate form.

그런데, 암모니아는 독성을 지니고 있어 수중 생태계를 위협할 뿐만 아니라 질산염화하는 과정에서 수계의 용존산소를 소모하게 되어 수계를 혐기화시키게 된다고 하는 문제점이 있다. 또한, 암모니아는 산도 및 온도 등 환경 여건에 따라 가스형태로 발산되며, 이 때 악취가 유발된다고 하는 문제점이 있다.However, ammonia has a problem in that it is toxic and not only threatens the aquatic ecosystem but also consumes dissolved oxygen in the water in the process of nitrating, thereby causing the water to be anaerobic. In addition, ammonia is emitted in the form of a gas according to environmental conditions such as acidity and temperature, and there is a problem that odor is caused at this time.

따라서, 본 발명의 목적은, 호소의 바닥층의 혐기화를 억제시킬 수 있으며 호소수중의 질소를 효과적으로 제거할 수 있는 호소정화공법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide an appeal purification method which can suppress the anaerobicization of the bottom layer of an appeal and can effectively remove nitrogen in the appeal water.

The plant 15 is planted so that an extended plant band is formed. The bottom layer 11 of the appeal is provided with a circulation device 21 to flow the appeal water 13 in a certain direction, the circulation device 21 is configured in the form of an underwater stirrer or a water pump, and the size and size of the appeal It may also be configured in plural in consideration of the flow rate.

순환장치(21)의 일측에는 호소수(13)의 산소농도를 높일 수 있도록 폭기장치(23)가 구비되어 있으며, 폭기장치(23)에는 호소의 외부로부터 호소수(13)에 공기를 공급할 수 있도록 일단이 블로어(25)에 연결된 공기공급관(27)의 타단이 연결되어 있다.One side of the circulation device 21 is provided with an aeration device 23 to increase the oxygen concentration of the appealing water 13, the aeration device 23 once to supply air to the appealing water 13 from the outside of the appeal The other end of the air supply pipe 27 connected to the blower 25 is connected.

한편, 폭기장치(23)의 일측 수중에는 호소수(13)를 여과할 수 있도록 여과장치(31)가 구비되어 있으며, 여과장치(31)는 내부에 여과매질 및 수중의 인성분을 섭취하여 증식되는 미생물담체가 충전된 별도의 여과조(32)를 사용할 수 있다. 여기서, 여과매질은 모래, 세라믹, 자갈 등의 무기질 천연재와 대나무, 참나무, 숯등의 유기질 천연재 및 합성수지류 등을 이용할 수 있다.On the other hand, one side of the aeration device 23 is provided with a filtration device 31 so as to filter the lake water 13, the filtration device 31 is grown by ingesting the filtration medium and phosphorus in the water therein A separate filtration tank 32 filled with a microbial carrier may be used. Here, the filter medium may use inorganic natural materials such as sand, ceramics, gravel, organic natural materials such as bamboo, oak, charcoal, synthetic resins, and the like.

여과조(32)의 일측에는 호소수(13)를 내부로 유입할 수 있는 유입장치(미도시)를 구비한 유입구(33)가 형성되어 있으며, 대향측에는 처리된 여과수를 여과조(32)의 외부로 배출할 수 있도록 배출장치(미도시)를 구비한 배출구(34)가 형성되어 있다. 여과조(32)의 저부에는 인성분 등을 섭취하여 증식된 미생물이 탈리된 슬러지를 수집할 수 있도록 슬러지수집부(35)가 형성되어 있으며, 슬러지수집부(35)에는 호소의 외부로 슬러지를 인출할 수 있도록 일단이 호소의 외부의 인출장치(37)에 연결된 인출배관(38)의 타단이 연결되어 있다.One side of the filtration tank 32 is formed with an inlet 33 having an inlet device (not shown) for introducing the appealing water 13 into the interior, and the treated filtration water is discharged to the outside of the filtration tank 32 on the opposite side. A discharge port 34 having a discharge device (not shown) is formed to allow. The sludge collection part 35 is formed in the bottom part of the filtration tank 32 so that the sludge collected by ingesting a phosphorus component etc. can be removed, and the sludge collection part 35 takes sludge out of the appeal. One end is connected to the other end of the withdrawal pipe 38 connected to the withdrawal device 37 outside of the appeal.

이러한 구성에 의하여, 순환장치(21)가 구동되면 호소수(13)는 호소의 둘레방향을 따라 어느 일 방향으로 일정하게 흐름을 형성하게 되고, 이 때 블로어(25) 및 폭기장치(23)가 구동되면 유동하는 호소수(13)에 미세한 기포형태로 산소를 공급하게 된다.By this configuration, when the circulation device 21 is driven, the appealing water 13 forms a constant flow in one direction along the circumferential direction of the appeal, and at this time, the blower 25 and the aeration device 23 are driven. When oxygen is supplied to the flowing lake water 13 in the form of fine bubbles.

호소수(13)의 흐름이 형성되고 용존산소의 용도가 높아지게 됨에 따라 수중생물에 위해를 가하는 암모니아태로 수중에 존재하는 질소성분은 질산염태로 전환되며, 호소수(13)가 혐기화되어 용출되었던 인성분은 금속염의 형태로 안정화된다. 호소의 물가선을 따라 식재된 정수식물(15)은 수중의 질산염태를 섭취하여 이를 에너지원 및 성장에 필요한 세포의 증식에 사용하게 된다.As the flow of lake water (13) is formed and the use of dissolved oxygen increases, the nitrogen component in the water is converted into nitrate, which causes harm to aquatic organisms, and the toughness of the lake water (13) is anaerobic and eluted. The powder is stabilized in the form of metal salts. The purified water plant (15) planted along the strand of the appeal is to take the nitrate in water and use it for the growth of energy sources and cells necessary for growth.

이렇게 수중의 질소성분을 에너지원으로 정수식물(15)이 성장/증식하게 되면 호소로부터 정수식물(15)을 분리제거함으로써 호소수(13)중의 질소성분의 제거가 이루어지게 된다.When the purified plant 15 is grown / proliferated using the nitrogen component in the water as an energy source, the nitrogen component in the lake water 13 is removed by separating and removing the purified plant 15 from the appeal.

한편, 유입장치에 의해 유입구로 유입된 호소수(13)는 여과매질에 의해 여과되고 수중의 인성분은 미생물의 증식 및 에너지원으로 사용됨으로써 호소수(13)의 인성분의 농도는 감소하게 된다. 인성분을 섭취하여 증식된 미생물은 소정 기간이 경과하게 되면 미생물담체로부터 탈리되어 슬러지수집부(35)에 수집되고, 수집된 슬러지를 인출장치(37) 및 인출배관(38)을 통해 호소의 외부로 인출제거되도록 함으로써 호소의 수계로부터 인성분의 제거가 이루어지게 된다.On the other hand, the lake water 13 introduced into the inlet by the inlet device is filtered by the filter medium and the phosphorus component in the water is used as the growth and energy source of the microorganism, so that the concentration of the phosphorus component of the lake water 13 is reduced. The microorganisms grown by ingesting the phosphorus component are detached from the microbial carrier when a predetermined period has elapsed and collected in the sludge collection unit 35, and the collected sludge outside the appeal through the extraction device 37 and the withdrawal pipe 38. The removal of the phosphorus component is achieved by removing the phosphorus component from the water system of the appeal.
