Description

친환경적 재활용 오니를 이용한 조경토 제조방법{Landscape Soil Manufacturing Method using environment-friendly sludge}Landscape Soil Manufacturing Method using environment-friendly sludge}

본 발명은 조경토 제조방법에 관한 것으로, 상세하게는 제조비용이 절감되고, 환경오염의 우려가 없으며, 수목에 적합하고, 품질이 균일한 친환경적 재활용 오니를 이용한 조경토 제조방법에 관한 것이다. The present invention relates to a method for manufacturing landscaping soil, and more particularly, to a method for manufacturing landscaping soil using environmentally friendly recycling sludge suitable for trees and having no fear of environmental pollution, and suitable for trees.

최근 들어 대도시를 중심으로 친환경 생태도시 구축을 위한 도시녹화사업을 적극적으로 전개하여 도시녹지를 보전하는 데에 역점을 두고 있으나, 대도시의 경우 녹화가 가능한 토지를 확보하기가 사실상 어려운 것이 현실이다.Recently, the city has focused on preserving urban green space by actively carrying out urban greening projects to build eco-friendly ecological cities, but it is difficult to secure land that can be greened in large cities.

특히 녹지가 절대적으로 부족한 도심부의 경우 거의 모든 토지에 건물이 들어서 있어서 건물을 해체하지 않으면서 녹지로 조성하는 것은 거의 불가능하다. 또한 도심부의 토지는 가용지가 있다 해도 높은 토지 가격으로 인해 녹지를 조성하는데 막대한 비용이 소요되므로 도시 녹화가 사실상 불가능한 실정이다.Especially in urban areas where there is an absolute shortage of green space, almost all the land contains buildings, so it is almost impossible to create green space without dismantling the building. In addition, urban land is in fact impossible to green the city, even if there is available land, because of the high cost of land, enormous costs are required to create green space.

이에 따라 도심부에서 녹지를 확보하기 위하여 건축물의 상부에 녹화를 시행하는 경우가 증가하고 있다.Accordingly, in order to secure green spaces in urban areas, greening of the upper part of buildings is increasing.

이외에도 삶의 질 향상으로 도시뿐만 아니라 인간이 거주하는 지역에는 점차 조경에 대한 관심이 높아지고 있으며, 이로 인해 조경에 적합한 조경토의 필요성이 꾸준히 제기되고 있다. In addition, due to the improvement of quality of life, interest in landscaping is gradually increasing not only in cities but also in areas where humans live, and this necessitates the need for landscaping land suitable for landscaping.

하지만 현재 조경식재용으로, 퇴비나 유기질비료 또는 검증되지 않은 유해성 폐기물 오니를 흙과 혼합하여 제조된 조경토가 사용되고 있다.However, for landscaping, landscaping soil produced by mixing compost, organic fertilizer or unproven hazardous waste sludge with soil is used.

이러한 조경토의 경우, 퇴비 또는 유기질 비료를 사용하기 때문에 경비가 상승하며, 현장에서 직접 제조하여 사용하기 때문에, 제조시간이 많이 소요된다.In the case of such landscaping, the cost increases because of the use of compost or organic fertilizers, and because it is manufactured and used directly on-site, it takes a lot of manufacturing time.

또한 상기 조경토는 제조시 검증받지 않은 유해성 폐기물 등을 원료로 사용하기 때문에 환경오염을 일으킬 가능성이 매우 높다.In addition, the landscaping soil has a high possibility of causing environmental pollution because it uses hazardous wastes, etc., which have not been verified at the time of manufacture.

그리고 상기 조경토는 현장에서 혼합이 이루어지기 때문에, 정확한 혼합비율을 맞추기가 어렵고, 이로 인해 적합한 토양을 수목에 제공하기 어려운 문제점이 있다.And because the landscaping soil is mixed in the field, it is difficult to match the exact mixing ratio, it is difficult to provide a suitable soil to trees because of this.

더불어 상기 조경토는 소포장된 비료를 사용하기 때문에, 폐기물이 다량으로 발생하는 문제점이 있다.In addition, the landscaping soil uses a small packaged fertilizer, there is a problem that a large amount of waste occurs.

상기와 같은 과제를 해결하기 위한 본 발명은, 제조비용이 절감되고, 환경오염의 우려가 없으며, 수목에 적합하고, 품질이 균일한 친환경적 재활용 오니를 이용한 조경토 제조방법을 제공하는 것을 해결하려는 과제로 한다.The present invention for solving the above problems, the manufacturing cost is reduced, there is no fear of environmental pollution, suitable for trees, the problem to be solved to provide a landscaping soil manufacturing method using environmentally friendly recycling sludge with uniform quality. Shall be.

상기 표 1에 해당하는 폐수처리오니에 대한 퇴보원료지정서를 도 1 내지 도 5로 첨부하였다.Degradation raw material specification for the wastewater treatment sludge corresponding to Table 1 is attached to FIGS.

이와 같은 폐수처리오니의 혼합물 중 함량은 화장품 제조업 폐수처리오니 7~12중량%, 유가공 식품제조 폐수처리오니 7~12중량%, 곡물가공 식품제조 폐수처리오니 7~12중량%, 감자가공 식품제조 폐수처리오니 12~17중량%,옥수수 전분류 제조 폐수처리오니 12~17중량%로 조절한 이유는 조경토로 사용할 수 있는 가장 적절한 무기물 및 유기물의 함량이 되도록 하기 위함이며, 그 결과는 하기 표 2를 보면 확인할 수 있다.The content of the mixture of wastewater treatment sludge is 7-12% by weight of wastewater treatment sludge for cosmetic manufacturing, 7-12% by weight of wastewater treatment sludge for dairy foods, 7-12% by weight of wastewater treatment sludge for grain processed foods, food processing for potato processing 12 to 17% by weight of wastewater treatment sludge, corn starch production The reason for adjusting to 12 to 17% by weight of waste sludge is to make the most suitable inorganic and organic contents that can be used as landscape soil, and the results are shown in Table 2 below. You can see this.

또한 본 발명에서 사용되는 미생물제는 숙성퇴비의 제조에 사용되는 많은 미생물 중에서 본 발명에서와 같은 조경토의 제조에 가장 적합한 미생물을 발명자의 시험에 의하여 선정된 것들로서 혼합물 중 포함되는 최적의 함량은 3~7중량%, 더욱 바람직하게는 5중량%이다.In addition, the microorganisms used in the present invention, among the many microorganisms used for the production of mature compost, the most suitable microorganisms selected by the inventors' tests as the most suitable for the preparation of the landscape soil as in the present invention is contained in the mixture is 3 ~ 7% by weight, more preferably 5% by weight.

한편 톱밥 5중량%, 황토 30중량%, 화장품 제조업 폐수처리오니 10중량%, 유가공 식품제조 폐수처리오니 10중량%, 곡물가공 식품제조 폐수처리오니 10중량%, 감자가공 식품제조 폐수처리오니 15중량%, 옥수수 전분류 제조 폐수처리오니 15중량% 및, 미생물제 5중량%로 혼합되는 혼합물을 이용하여 본 발명에 따라 제조되는 조경토를 현재 시판되는 퇴비와의 성분을 비교하여 비교표를 첨부하며, 이와 비교하기 위하여, 퇴비 국가 규격 성분함량을 제시한다.Meanwhile, sawdust 5 wt%, loess 30 wt%, cosmetic manufacturing wastewater treatment sludge 10 wt%, dairy food manufacturing wastewater treatment sludge 10 wt%, grain processing food manufacturing wastewater treatment sludge 10 wt%, potato processing food manufacturing wastewater treatment sludge 15 wt% %, Corn starch production wastewater treatment sludge 15% by weight, and using a mixture mixed with 5% by weight of microbial agent to compare the components of the landscaping soil prepared according to the present invention with the composting commercially available, and attach a comparison table, For comparison, the compost national standard ingredient content is presented.

상기 표 2에서 보는 바와 같이, 유기물의 함량이 25% 이상 되는 시판 퇴비나 유기질 비료를 이용하여 현장에서 조경토를 만들 시, 품질이 균일하도록 혼합이 불가능하며, 원료가 편중되게 모일 수 있어 2차 발효에 의한 가스, 열 등에 의해 조경수목의 생육 저하가 발생하고 심할 때는 고사 되는 등의 우려가 있으며, 또한 검증되지 않은 유해성 폐기물을 사용할 경우 중금속에 의한 환경 및 토양을 오염시키고 수목이 생육 저하 및 고사 등의 위험을 초래할 수 있다.As shown in Table 2, when making the landscaping soil in the field using commercial compost or organic fertilizer having an organic content of more than 25%, it is impossible to mix so that the quality is uniform, and the raw materials can be gathered to be concentrated secondarily. There is a risk of deterioration of landscaping trees due to gas, heat, etc. due to fermentation, and severe deaths.In addition, when unvalidated hazardous wastes are used, the environment and soil caused by heavy metals are contaminated, and trees are degraded and killed. This may cause a danger.

그러나 본 발명의 경우에는 15 내지 20중량%로서 완숙 발효를 하였기 때문에 시판 퇴비에서 발생하는 문제점은 전혀 찾아볼 수 없는 장점이 있다.However, in the case of the present invention, since the mature fermentation is carried out as 15 to 20% by weight, there is no advantage in finding problems in commercial compost.

또한 본 발명의 조경토는, 사용되는 원료가 환경 및 토양에 유해한 중금속(비소, 카드뮴, 수은, 납, 크롬 구리, 니켈, 아연) 성분이 퇴비 비료에 정해진 국가 규격보다 훨씬 적게 함유된 원료로 제품이 생산되므로 환경 및 토양에 무해한 친환경적인 장점이 있다.In addition, the landscaping soil of the present invention is a raw material containing a lot of heavy metals (arsenic, cadmium, mercury, lead, chromium copper, nickel, zinc) components harmful to the environment and soil than the national standards set in the compost fertilizer products Because it is produced there is an environmentally friendly advantage harmless to the environment and soil.

그리고 본 발명의 조경토는 기획된 제조공정을 거쳐 생산되므로 그 품질이 균일하게 우수하다.And the landscaping soil of the present invention is produced through a planned manufacturing process, the quality is uniformly excellent.

더불어 본 발명의 조경토는 미생물을 투입하여 숙성, 발효 공정으로 생산되기 때문에, 토양 미생물 활성화에도 기여하므로 토양을 중화시키며, 우천시 주변에서 흡수되는 물질도 중화시켜 주는 친환경적인 정화능력 역할도 한다.In addition, the landscaping soil of the present invention is produced by the aging, fermentation process by adding microorganisms, thus contributes to the activation of soil microorganisms to neutralize the soil, and also serves as an environmentally friendly purification ability to neutralize the material absorbed in the rain.
