정수장 슬러지를 이용한 토양개량제 제조방법{METHOD OF MANUFACTURING SOIL CONDITIONER}Soil improver manufacturing method using water treatment plant sludge {METHOD OF MANUFACTURING SOIL CONDITIONER}

본 발명은 토양개량제 제조방법에 관한 것으로 특히, 환경오염의 원인이 되는 산업 폐기물을 자원화하기 위하여 재활용할 수 있는 정수장 슬러지를 이용한 토양개량제 제조방법에 관한 것이다.The present invention relates to a method for producing a soil improver, and more particularly, to a method for producing a soil improver using water treatment plant sludge that can be recycled to recycle industrial waste causing environmental pollution.

통상적으로, 정수장 슬러지는 수돗물을 정수하는 과정에서 수중의 오탁물질이 침전되어 있는 진흙상태로서, 원수(原水)에 포함된 부유물 및 중금속과 같은 오염물질을 제거시키기 위해 황산알루미늄과 같은 무기계 응집제 또는 고분자 응집제 등이 사용되며 또한 대장균 및 일반세균의 화학적 살균처리법으로 염소 또는 오존 처리과정을 거치게 됨에 따라 정수장 슬러지는 오염된 상태로서 70∼80%의 높은 함수율과 유기물을 다량 포함하고 있다. 따라서 상기 정수장 슬러지는 농축, 탈수, 건조과정을 거친 다음 대부분 쓰레기 매립장에 매립되거나 수송선으로 운반되어 바다에 투기되고 있는 실정으로 환경오염의 요인이 되고 있으며, 처리에 많은 경비가 소요되고 있는 실정이다.In general, water purification plant sludge is a mud state in which contaminants in water are precipitated in the process of purifying tap water. An inorganic flocculant or a polymer such as aluminum sulfate is used to remove contaminants such as suspended solids and heavy metals contained in raw water. As flocculant is used and the chemical sterilization method of Escherichia coli and general bacteria is treated with chlorine or ozone, water purification plant sludge is contaminated and contains 70 ~ 80% of high moisture content and large amount of organic matter. Therefore, the water purification plant sludge has been concentrated, dehydrated, and dried, and most of them are landfilled in landfills or transported by transport ships, and are being dumped in the sea, causing environmental pollution, and a lot of expenses are required for treatment.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로 본 발명의 목적은 정수장 슬러지를 재활용하여 환경오염을 방지함은 물론, 폐기물을 처리하기 위한 경비소모를 없애고 자원의 소모를 줄일 수 있는 정수장 슬러지를 이용한 토양개량제 제조방법을 제공함에 있다.The present invention is to overcome the above-mentioned problems, the object of the present invention is to recycle the water purification plant sludge to prevent environmental pollution, as well as to eliminate the waste of waste treatment and to reduce the consumption of resources. The present invention provides a method for preparing a soil improving agent.

상기 목적을 달성하기 위해 본 발명은 정수장 슬러지 73∼83 중량%와 석회 15∼25 중량%, 유효인산 0.5∼2 중량%, 그리고 철, 아연, 망간, 구리, 몰리브덴의 금속염, 그리고 붕소 등의 미량 원소를 첨가하여 소정의 장치에서 혼합시킨 다음 분쇄기에서 일정한 크기로 분쇄하는 공정을 통해 완성됨을 특징으로 한다.In order to achieve the above object, the present invention provides 73 to 83% by weight of sludge for water purification plant, 15 to 25% by weight of lime, 0.5 to 2% by weight of effective phosphoric acid, and trace amounts of metal salts of iron, zinc, manganese, copper, molybdenum, and boron. The element is added, mixed in a predetermined apparatus, and then pulverized to a predetermined size in a mill.

이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

먼저, 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 흐트릴 수 있는 경우 그 상세한 설명을 생략한다.First, in describing the present invention, if a detailed description of related known functions or configurations may obscure the gist of the present invention, the detailed description thereof will be omitted.

본 발명은 폐기물로서 주로 매립되는 정수장 슬러지와 석회 및 유효인산 을 혼합하여 양질의 토양개량제를 제조하게 된다.The present invention is to produce a high quality soil improver by mixing the water purification plant sludge and lime and effective phosphoric acid mainly as waste.

위를 더욱 자세하게 설명하면 먼저, 정수장 슬러지를 수거하여 수분이 10% 이하가 되도록 탈수장치 및 건조장치에서 수분을 제거한 후 분쇄장치에서 미세하게 분쇄한다. 그리고 상기 정수장 오니 73∼83 중량%와 석회 15∼25 중량%, 유효인산 0.5∼2 중량%, 그리고 작물의 미량원소 결핍을 보완하기 위하여 철, 아연, 망간,구리, 몰리브덴의 금속염, 그리고 붕소 등을 미량 첨가하여 소정의 장치를 이용하여 혼합시킨 다음 분쇄기에서 일정한 크기로 분쇄하는 공정을 통해 양질의 토양개량제가 완성된다.More detailed description of the above, first, to remove the water from the dehydration apparatus and drying apparatus to collect water sludge to less than 10% water, and then finely pulverize in the crusher. And 73 to 83% by weight of the sludge plant, 15 to 25% by weight of lime, 0.5 to 2% by weight of effective phosphoric acid, and metal salts of iron, zinc, manganese, copper, molybdenum, and boron to compensate for the lack of trace elements in crops. By adding a small amount of mixed by using a predetermined device and then crushed to a constant size in the mill through a good quality of the soil improver is completed.

이상으로 살펴본 바와 같이, 본 발명에 따른 정수장 슬러지를 이용한 토양개량제 제조방법은 매립되는 폐기물을 재활용하게 됨에 따라 환경오염을 방지할 수 있으며 특히 자원의 낭비를 줄일 수 있는 경제적인 효과가 있다.As described above, the method for manufacturing a soil improver using water purification plant sludge according to the present invention can prevent environmental pollution by recycling the landfill waste, and in particular, has an economic effect of reducing waste of resources.

화학비료 남용으로 인하여 산성화된 토양을 개량하여 땅의 산성화를 막고 식물에 유익한 미네랄을 공급하여 지력을 증진시키며, 슬러지 중의 유기물에 의한 토양의 수분흡수와 공기가 잘 통하도록 부드러운 토질로 만들어주어 식물성장이 용이하도록 한다.Improving acidified soil by chemical fertilizer abuse prevents acidification of soil and supplies beneficial minerals to plants to enhance intellect. To facilitate this.
