Description
본 발명은 피조개 양식장의 생산성 향상 방법에 관한 것이며, 더욱 상세하게 5mm이하의 입자 크기를 가진 제강슬래그와 피조개 양식장의 오염된 저질이 형망선에 의해 상호 간에 섞여, 오염된 저질 및 저층 수질을 개선함으로써 피조개의 생산성을 향상시키는 피조개 양식장의 생산성 향상 방법에 관한 것이다.The present invention relates to a method for improving productivity of a shellfish farm, and more specifically, contaminated soil quality of a steelmaking slag having a particle size of 5 mm or less and the shellfish farm are mixed with each other by a reticle, thereby improving the polluted water quality and the bottom water quality. The present invention relates to a method for improving productivity of a shellfish farm.
피조개 양식의 경우, 우리나라에서는 1970년대 중반 이후 천연 채묘에 의한 종묘 생산이 개시되면서 진해만을 중심으로 시작되었다. 그리고, 1980년대 들어서는 수출대상 품종으로 각광을 받기 시작하였으며, 1980년대 이후 양식의 확대에 따라 피조개의 생산 물량이 급증하여 수산물 수출에 있어서, 단일 품종으로는 최대치를 나타내었다.In the case of shellfish farming, the production of seedlings by natural seedlings began in the mid-1970s in China. And in the 1980s, it began to gain attention as an exportable breed, and since the 1980s, the production volume of seashells increased rapidly with the expansion of aquaculture.
그러나, 1987년부터는 서서히 양식 어장의 생산력이 떨어지기 시작하여 1995년 이후에는 1986년의 최대치 대비 1/10 수준까지 피조개의 생산량이 현저히 감소하였다. 이와 같은 생산성 부진의 근본적인 원인은 전반적으로 양식장의 노후화 및 황폐화에 따른 생산성 저하로 간주되며, 이러한 현상을 계속될 것으로 전망된다.However, since 1987, the production capacity of aquaculture farms began to drop gradually, and since 1995, the production of shellfish has decreased markedly to 1/10 of the maximum in 1986. The root cause of such productivity deterioration is generally regarded as a decrease in productivity due to aging and deterioration of the farm, and it is expected to continue.
일반적으로, 피조개의 장기 양식에 따른 저질오염 현상을 막기 위해 가장 널리 시행되고 있는 방법으로는 황토 살포를 통한 경운 및 객토법을 들 수 있다. 객토는 일찍부터 농업분야에서 토질을 개량하기 위하여 적용되어 왔다. 수산분야에서 객토법은 특히 피조개 양식장을 중심으로 수년 전부터 시도되어 왔으며, 객토법의 재료로 황토를 사용하여 왔다. 또한, 일본의 경우 오염된 저질개선을 위하여 패류 양식장에 점토를 살포한 후 그 결과를 살펴보면, 저질에 의한 용존산소 소비는 약 40%, 인산염의 용출은 50~90%가 억제되는 것으로 보고된 바도 있다. In general, the most widely used methods to prevent low pollution caused by the long-term culture of the shellfish include tillage and landscaping through the use of loess. Land has been applied early to improve soil quality in agriculture. In the field of fisheries, landscaping has been tried for many years, especially in the shellfish farms, and has been used ocher as a material for landscaping. In addition, in Japan, after spraying clay on shellfish farms to improve polluted water quality, it was reported that about 40% of dissolved oxygen consumption and 50 ~ 90% of phosphate were suppressed due to low quality. have.
그러나, 이러한 황토 살포법은 살포시 발생하는 수일 내지 일주일 정도의 부유물의 부유시간 과다에 의해 기초생태계인 플랑크톤에 단기적으로 영향을 미칠 수 있다. 이로 인하여, 장기적인 관점에서는 육상에서 황토를 채취하여 공급하는데 한계가 있을 뿐만 아니라, 환경친화적인 관점에서도 육상환경의 파괴라는 문제점이 존재한다. 아울러, 최근에는 황토 살포에 따른 2차적인 유기물 오염 및 저질산성화 문제도 대두되고 있는 실정이다.However, this method of loess spreading may affect the basic ecosystem plankton in the short term due to excessive floating time of suspended solids of several days to a week. Therefore, in the long term, not only is there a limit to extracting and supplying soil from the land, but also there is a problem of destruction of the land environment from an environmentally friendly point of view. In addition, in recent years, secondary organic contamination and low nitric acidization problems caused by the spread of ocher are also emerging.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명은 5mm 이하의 입자 크기를 가진 제강슬래그를 사용하여 황폐화되거나 노후화된 패류 양식장의 환경을 향상시킴으로써, 피조개와 같은 저서성 양식 패류의 생존율 및 생산성을 향상시키는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, the present invention improves the environment of the desolated or aging shellfish farm using a steelmaking slag having a particle size of 5mm or less, so that benthic cultures such as clams It aims at improving the survival rate and productivity of shellfish.
또한, 본 발명은 제철 공정에서 발생한 부산물인 제강슬래그를 재활용하여 경제적인 피조개 양식장의 생산성 향상 방법을 제공함을 목적으로 한다.In addition, an object of the present invention is to provide a method for improving productivity of shellfish farms by recycling steelmaking slag which is a by-product generated in a steelmaking process.
아울러, 본 발명은 황토 입자 크기보다 큰 입자 크기를 가진 제강슬래그를 사용함으로써 부유물에 의한 2차 오염을 방지하여, 친환경적인 피조개 양식장의 생산성 향상 방법을 제공함을 목적으로 한다.In addition, an object of the present invention is to provide a method for improving productivity of an ecologically-sealed farm by preventing secondary pollution by suspended matter by using steelmaking slag having a particle size larger than that of ocher particles.

이하, 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, the sea area to which the present invention is applied to the method of improving productivity of the shellfish farm is referred to as a "guest land area", and the sea area to which the present invention is not applied to the productivity enhancement method to the shellfish farm is referred to as a "unvisited land area".
일반적으로, 저서성 양식 패류 양식장(이하, 피조개 양식장이라 한다)의 저질(bottom material) 및 저층 수질은 저서성 양식 패류(예컨대, 피조개)의 생육에 있어 중요한 인자로 작용한다. 따라서, 피조개의 생산성을 향상시키기 위해서는 저질 및 저층 수질이 향상되어야 한다. 이는, 저질 및 저층의 수질이 양호해질수록 식물 플랑크톤의 개체수가 많아지게 되고, 식물 플랑크톤의 개체수가 많아질수록 식물 플랑크톤을 섭식하는 피조개의 생존율이 증가하기 때문이다. In general, the bottom and bottom water quality of benthic aquaculture shellfish farms (hereinafter referred to as clam farms) serves as an important factor in the growth of benthic aquaculture shellfish (eg clams). Therefore, in order to improve the productivity of the shellfish, the low quality and the low water quality should be improved. This is because, as the water quality of the low and low layers becomes better, the population of phytoplankton increases, and as the population of phytoplankton increases, the survival rate of the clams that feed on phytoplankton increases.
피조개 양식장의 저질 및 저층 수질을 향상시키기 위한 방법은 다음과 같다.The methods for improving the quality and water quality of shellfish farms are as follows.
우선, 제철 공정에서 발생된 제강슬래그 중에서 5mm이하의 입자 크기를 가진 제강슬래그가 분별된다. First, steelmaking slag having a particle size of 5 mm or less is discriminated among steelmaking slags generated in the steelmaking process.
다음으로, 분별된 제강슬래그가 오염된 저질이 포함된 피조개 양식장에 복토된다. 황토 대신에 제강슬래그를 피조개 양식장에 복토하는 이유는 다음과 같다. 제강슬래그의 입자의 크기는 황토 입자 크기보다 크고, 밀도(2.5×103㎏/㎥)도 황토의 밀도(1.960×103㎏/㎥)보다 크다. 제강슬래그는 황토보다 입자의 크기 및 밀도가 크기 때문에, 황토의 침강 속도보다 침강 속도가 빠르며, 미세 입자의 부유시간도 또한 단축된다. 일반적으로, 황토 입자의 부유시간은 수일 내지 일주일 정도의 시간이 소요된다. 반면, 제강슬래그의 부유시간은 2시간 정도 소요되어, 부유시간의 단축으로 적용 면적 이외에 외부로 부유로 인한 미세 입자의 유출이 거의 없다. 따라서, 부유물에 의한 양식장의 2차 오염이 방지된다. 아울러, 복토 작업과정 중 오탁방지막 등의 추가 시설이 필요치 않아 경제적이다.The fractionated steelmaking slag is then covered in a shellfish farm containing contaminated sediment. The reason for applying the steel slag in the shellfish farm instead of the loess is as follows. The size of the steelmaking slag is larger than that of the ocher particles, and the density (2.5 × 10 3 kg / m 3 ) is also greater than the density of the loess (1.960 × 10 3 kg / m 3 ). Since steelmaking slag has a larger particle size and density than ocher, the sedimentation rate is faster than that of ocher, and the suspension time of the fine particles is also shortened. In general, the residence time of the ocher particles takes several days to a week or so. On the other hand, the floating time of the steelmaking slag is about 2 hours, the flow of the fine particles due to the floating out of the outside in addition to the application area due to the shortening of the floating time. Therefore, secondary contamination of the farm by the float is prevented. In addition, it is economical because no additional facilities such as antifouling film are needed during the cover work process.
마지막으로, 복토된 제강슬래그가 형망선에 의해서 경운 및 객토되어, 오염된 저질과 섞인다. 형망선은 갈코리 형상의 형망이 장착된 어선을 말한다.Finally, the covered steelmaking slag is tilled and covered by a mesh network, mixed with contaminated sediments. A fishing net is a fishing boat equipped with a galley-shaped shape net.
오염된 저질과 섞인 제강슬래그의 객토 두께는 2㎝ 이하가 바람직하다. 이는, 오염된 저질과 섞인 제강슬래그의 두께가 2㎝ 이상에서는 피조개의 퇴적층으로의 잠입률이 다소 떨어지기 때문이다. 객토 두께란 제강슬래그 또는 황토 등의 입자가 피조개 양식장의 오염된 저질과 섞여 피조개 양식장의 상부에 적층되는 두께를 말한다. 한편, 제강슬래그의 객토량은 제강슬래그의 밀도(2.5×103㎏/㎥), 객토 면적, 및 객토 두께에 의해 결정된다. 예를 들어, 2cm 이하의 객토 두께를 가진 피조개 양식장의 1㏊당 제강슬래그의 객토량은 500톤(=2.5×103㎏/㎥×10000㎡×0.02m) 이하가 바람직하다.It is preferable that the thickness of the landfill of the steelmaking slag mixed with the contaminated sediment is 2 cm or less. This is because when the thickness of the steelmaking slag mixed with the contaminated sediment is 2 cm or more, the penetration rate into the sedimentary layer of the clam decreases slightly. The grain thickness refers to a thickness in which particles such as steelmaking slag or loess are mixed with contaminated soil of the shellfish farm and stacked on top of the shellfish farm. On the other hand, the volume of the steelmaking slag is determined by the density of the steelmaking slag (2.5 × 10 3 kg / m 3 ), the area of the clay, and the thickness of the clay. For example, the volume of the steel slag per square kilometer of the shellfish farm with a thickness of less than 2 cm is preferably 500 ton (= 2.5 × 10 3 kg / m 3 × 10000
이하에서는, 표 1을 참조하여 피조개 양식장에 객토되는 입자의 크기 및 입자의 종류에 따른 피조개의 생존율 및 피조개의 퇴적층으로의 잠입률을 살펴본다. Hereinafter, with reference to Table 1 looks at the survival rate of the shellfish according to the size and particle type of the shelled in the shellfish farm and the penetration rate into the deposited layer of the shellfish.
2cm 이하의 객토 두께를 가진 피조개 양식장에서, 입자 종류에 따른 피조개의 퇴적층으로의 잠입률 및 생존율은 다음과 같다. 퇴적층 잠입률이란 피조개가 저질의 퇴적층으로 들락날락하는 비율을 말한다. In shellfish farms with a thickness of less than 2 cm, the infiltration rate and survival rate of the shellfish according to the particle types are as follows. Sediment infiltration rate refers to the rate at which the clam enters and falls into a low quality sediment.
표 1에 도시된 바와 같이, 피조개의 퇴적층으로의 잠입률은, 황토를 객토했을 때는 56%인 반면 제강슬래그를 객토했을 때에는 58~71%이므로, 황토를 피조개 양식장에 객토했을 때보다 제강슬래그를 피조개 양식장에 객토했을 때, 약 2% 내지 15% 정도 높다. 또한, 피조개의 생존율은, 황토를 객토했을 때는 59%인 반면 제강슬래그를 객토했을 때에는 61~64%이므로, 황토를 피조개 양식장에 객토했을 때보다 제강슬래그를 피조개 양식장에 객토했을 때, 약 2% 내지 5% 정도 높다. 따라서, 황토를 피조개 양식장에 객토했을 때보다 제강슬래그를 피조개 양식장에 객토했을 때, 피조개의 생존율 및 피조개의 퇴적층으로의 잠입률이 높다. 다만, 제강슬래그의 입자의 크기에 따라, 퇴적층의 잠입률 및 생존율이 차이가 있으므로, 이하에서는, 제강슬래그의 입자의 크기에 따라 피조개의 생존율, 및 피조개의 퇴적층으로의 잠입률을 살펴보기로 한다.As shown in Table 1, the infiltration rate into the sedimentary layers of the shellfish was 56% when the loess was covered, while 58 to 71% when the steel slag was covered. When visited to the shellfish farm, it is about 2% to 15% higher. In addition, the survival rate of the shellfish is 59% when the ocher is covered, whereas 61-64% is when the steel slag is cast, so about 2% when the steel slag is put in the shellfish farm than when it is put in the shellfish farm To about 5% higher. Therefore, when the steelmaking slag is put in the shelled farms than when the loess is put in the shelled farms, the survival rate of the shelled shells and the infiltration rate into the deposited layers of the shells are higher. However, since the infiltration rate and survival rate of the sediment layer are different depending on the size of the steelmaking slag, the survival rate of the clam and the infiltration rate into the sedimentary layer of the clam shell will be described according to the size of the steelmaking slag. .
표 1에 도시된 바와 같이, 5~10mm의 입자 크기를 가진 제강슬래그가 객토된 영역에서 피조개의 퇴적층으로의 잠입률은 58%, 생존율은 61%이다. 반면, 5mm이하의 입자 크기를 가진 제강슬래그가 객토된 영역에서 피조개의 퇴적층으로의 잠입률은 71%로서, 5~10mm의 입자 크기를 가진 제강슬래그가 객토된 영역에서 피조개의 퇴적층으로의 잠입률보다 13% 높다. 또한, 5mm이하의 입자 크기를 가진 제강슬래그가 객토된 영역에서 피조개의 생존율은 64%로서, 5~10mm의 입자 크기를 가진 제강슬래그가 객토된 영역에서의 피조개 생존율보다 3% 높다. 이는, 피조개가 퇴적층으로 들락날락하기가, 5~10mm의 입자 크기를 가진 제강슬래그가 객토됐을 때보다 5mm 이하의 입자 크기를 가진 제강슬래그가 객토됐을 때, 더욱 용이하기 때문이다. As shown in Table 1, the penetration rate into the sedimentary layers of the shell of the molten steel slag with the particle size of 5 ~ 10mm is 58%, the survival rate is 61%. On the other hand, the infiltration rate of the steel clad with the grain size of 5mm or less into the deposited layer was 71%, and the penetration rate of the steel clad with the grain size of 5 ~ 10mm into the deposited layer 13% higher than. In addition, the survival rate of the shellfish in the region covered with steel slag having a particle size of 5 mm or less is 64%, which is 3% higher than that of the shelled region of the steel slag having a particle size of 5-10 mm. This is because it is easier for the clam to enter and exit the sedimentary layer when the steel slag having a particle size of 5 mm or less is entered than when the steel slag having a particle size of 5 to 10 mm is entered.
결과적으로, 5mm 이하의 입자 크기를 가진 제강슬래그가 객토된 영역에서 피조개의 잠입률 및 생존율이 가장 높다. As a result, the infiltration rate and survival rate of the clam are the highest in the area covered with steelmaking slag having a particle size of 5 mm or less.
이하에서는, 도 1 및 도 2를 참조하여, 5mm이하의 입자 크기를 가진 제강슬래그가 객토된 객토 영역, 및 객토되지 않은 미객토 영역에서, 피조개의 생존율 및 비만도를 비교하여 살펴보기로 한다.Hereinafter, referring to FIG. 1 and FIG. 2, the survival rate and obesity of the shellfish in the unclaimed unclaimed soil region and the unsoiled soil region of the steel slag having a particle size of 5 mm or less will be described.
도 1은 객토 영역과 미객토 영역에서, 경과 기간에 따른 피조개 생존율의 변화를 비교한 그래프이다. 도 1에 도시된 바와 같이, 피조개의 생존율은 경과기간에 반비례한다. 피조개 생존율은 객토 영역 및 미객토 영역에서 0개월 내지 2개월 사이에서 현저히 감소하며, 경과기간이 증가할수록 피조개 생존율은 감소한다. 1 is a graph comparing the change in the survival rate of the shellfish according to the elapsed time in the region and the uncovered region. As shown in FIG. 1, the survival rate of the clam is inversely proportional to the elapsed time. The survival rate of the shellfish is markedly decreased between 0 and 2 months in the cultivated area and the undeveloped area, and as the lapse of time increases, the survival rate of the shellfish decreases.
객토 영역과 미객토 영역에서의 피조개 생존율을 비교하면 다음과 같다. 2개월 경과된 시점에서, 객토 영역에서의 피조개의 생존율은 약 20%인 반면, 미객토 영역에서의 피조개의 생존율은 약 7%에 불과하다. 또한, 12개월이 경과된 시점에서, 객토 영역에서의 피조개의 생존율은 약 10%인 반면, 미객토 영역에서의 피조개의 생존율은 거의 0%에 근접한다. 즉, 객토 영역에서 12개월이 경과된 시점의 피조개 생존율은 약 10%인 반면, 미객토 영역에서 2개월이 경과된 시점의 피조개 생존율이 10%미만인 점에 비추어, 객토 영역에서의 피조개의 생존율은 미객토 영역에서의 피조개 생존율보다 월등히 높다. Comparing the survival rates of clams in the unclaimed and undeveloped areas is as follows. At two months, the survival rate of the clam in the cover region is about 20%, while the survival rate of the clam in the uncovered region is only about 7%. In addition, at the time of 12 months, the survival rate of the clam in the cover region is about 10%, while the survival rate of the clam in the uncovered region is close to 0%. In other words, the survival rate of the shellfish in the uncovered area was about 10%, whereas the survival rate of the shellfish in the undeveloped area was less than 10%. It is much higher than the survival rate of shellfish in the unclaimed territory.
도 2는 객토 영역과 미객토 영역에서 피조개 채취시의 피조개 비만도를 비교한 그래프이다. 도 2에 도시된 바와 같이, 피조개의 비만도는 객토 영역에서 약 47.1%, 미객토 영역에서 약 46.5%로서, 객토 영역에서 생육된 피조개의 비만도가 미객토 영역에서 생육된 피조개의 비만도보다 약 0.6% 높다.2 is a graph comparing the degree of shellfish obesity at the time of collecting shellfish in an open soil region and an unpaved soil region. As shown in FIG. 2, the obesity degree of the clam was about 47.1% in the loam region, and about 46.5% in the unaccompanied region, and the obesity degree of the created loach in the loam region was about 0.6% higher than the obesity of the clam grown in the unacclaimed region. high.
결과적으로, 객토 영역에서 생육된 피조개가 미객토 영역에서 생육된 피조개보다 생존율 및 비만도가 높다. As a result, the survival rate and obesity of the shellfish grown in the uncovered region are higher than those of the shellfish grown in the unsoiled region.
