The present invention relates to a sewage sludge recycling apparatus and method in which water is separated into water and gas, and gas is released to the atmosphere by removing odors and water is discharged to a sewage treatment plant.

하수처리장에서는 막대한 양의 하수 슬러지가 지속적으로 발생되고 있으며, 이러한 하수 슬러지를 처리함에 있어, 가장 일반적인 처리방식은, 황무지나 매립지에 매립하는 것이다.In sewage treatment plants, huge amounts of sewage sludge are continuously generated, and in treating such sewage sludge, the most common treatment method is landfilling in wasteland or landfill.

그러나 황무지나 매립지는 매립할 수 있는 면적이 한정되어 있기 때문에 매립이 자유롭지 못하고 매립 허가조건도 매우 까다롭다. 또한 다른 분야에서 발생하는 다량의 폐기물이 함께 매립되므로 매립할 수 있는 장소가 급속히 고갈되고 있는 실정에 있으며, 매립지 선정에도 많은 어려움이 있어 지역적 분쟁과 사회적 문제를 야기하고 있다.However, because the waste land and landfills have a limited landfill area, landfilling is not free and the landfill permit conditions are very demanding. In addition, since a large amount of waste from other fields is buried together, the place for landfill is rapidly depleted, and there are many difficulties in selecting landfill sites, causing local conflicts and social problems.

또한 하수 슬러지를 매립하기 전에 어느 정도 탈수 및 건조시키고는 있지만, 그래도 함수율이 높기 때문에, 매립시 악취와 유독가스를 유발하여 공기를 오염시키고 땅으로 스며드는 침출수는 지하수를 오염시키는 원인이 되고 있다.In addition, although the sewage sludge is dewatered and dried to some extent before being landfilled, the water content is still high, so that leachate that contaminates the air by causing odors and toxic gases during landfilling and penetrates to the ground causes contamination of groundwater.

In the rotary impact drying and grinder 20, the scrubber 30 to separate the water separated from the electric shock-type drying and grinder 20 into a gas and a liquid and discharged to the outside, respectively, and in the scrubber 30 It comprises a odor remover 40 for purifying the separated gas to release to the atmosphere.

이러한 하수 슬러지 재활용 처리장치를 이용한 처리방법은, 도 2에 도시된 바와 같이 공급되는 하수 슬러지를 믹서(10)로 균일하게 혼합하는 전처리공정(100)과, 상기 전처리공정(100)에서 공급되는 하수 슬러지를 회전충격식 건조 및 분쇄기(20)로 미립 고형분과 수분으로 분리하는 건조 및 분쇄공정(200)을 수행하여 이루어진다.The treatment method using the sewage sludge recycling treatment apparatus includes a pretreatment step 100 for uniformly mixing the sewage sludge supplied to the mixer 10 as shown in FIG. 2, and the sewage water supplied from the pretreatment step 100. The sludge is made by performing a drying and grinding process 200 for separating the particulate solids and moisture into the rotary impact drying and milling machine 20.

전처리공정(100)에서는 재활용 처리하고자 하는 하수 슬러지를 건조 및 분쇄 공정을 위한 회전충격식 건조 및 분쇄기(20)에 투입하기 전에, 공급되는 하수 슬러지를 믹서(10)로 균일하게 혼합하여 함수율 55~60％가 유지되도록 하기 위한 것으로, 이는 회전충격식 건조 및 분쇄기(20)로 하수 슬러지를 처리함에 있어서 공급되는 하수 슬러지의 함수율이 55~60％일 때, 건조 및 분쇄효율이 가장 높고 함수율이 60％ 이상에서는 건조 및 분쇄공정이 이루어지지 않기 때문이다.In the pre-treatment process 100, the sewage sludge to be recycled is mixed uniformly with the mixer 10 before being introduced into the rotary impact type drying and crusher 20 for drying and crushing, and the water content 55 ~. It is intended to maintain 60%, which is the highest drying and grinding efficiency and the water content is 60, when the moisture content of the sewage sludge supplied in the treatment of sewage sludge with rotary impact drying and mill 20 is 55 ~ 60% It is because a drying and a grinding | pulverization process are not performed at% or more.

건조 및 분쇄공정(200)을 위한 회전충격식 건조 및 분쇄기(20)는 고정외통 내에 고속 회전이 가능한 회전내통을 구비하여 회전내통의 고속회전에 의한 원심력 및 충격을 이용한 것으로, 하수 슬러지를 회전내통에 공급하여 고속 회전시키면, 하수 슬러지에 함유된 수분은 원심력에 의해 고정외통으로 분리되어 다음 스크러버공정(300)을 위해 스크러버(30)로 이송되고, 수분제거로 인해 함수율 5％인 하수 슬러지는 회전내통내에서의 회전충격에 의해 미세한 분말로 분쇄된 후 원심력에 의해 비산되어 외부로 배출됨으로써 하수 슬러지를 미립 고형물과 수분으로 분리할 수 있게 된다.The rotary impact drying and pulverizer 20 for the drying and crushing process 200 is equipped with a rotary inner cylinder capable of high-speed rotation in a fixed outer cylinder and uses centrifugal force and impact by high-speed rotation of the rotary inner cylinder, and sewage sludge is rotated in an inner cylinder.

After supplying uniformly and uniformly mixing, 1500 kg / h of sewage sludge having a water content of 55 to 60% is preferably introduced into the rotary impact drying and pulverizer 20 for the drying and crushing process 200.

또한, 상기 함수율 5％의 하수 슬러지는 건조 및 분쇄공정(200)에서 분리된 미립 고형분을 공급하는 것이 보다 효율적인 것으로, 회전충격식 건조 및 분쇄 기(20)에 의해 수행되는 건조 및 분쇄공정(200)에서는 믹서(10)로부터 공급된 1500㎏/h의 하수 슬러지를 처리하여 분리된 750㎏/h의 미립 고형물중 500㎏/h는 믹서(20)로 리턴시키고, 270㎏/h의 미립 고형물은 외부로 반출함으로써 연료로서 사용한다.In addition, the sewage sludge having a water content of 5% is more efficient to supply the particulate solids separated in the drying and grinding process 200, and the drying and grinding process 200 performed by the rotary impact drying and grinding machine 20. ), 500 kg / h of the separated 750 kg / h of the particulate solids treated by 1500 kg / h of sewage sludge supplied from the mixer 10 is returned to the mixer 20, and 270 kg / h of the particulate solids is It is used as fuel by carrying out to the outside.

한편, 상기 회전충격식 건조 및 분쇄기(20)에 의한 건조 및 분쇄공정(200)에서 분리된 수분은 기체, 약간의 미세분말 및 물입자를 포함하고 있으며, 이 수분은 스크러버(30)로 공급되어 스크러버공정(300)을 수행함으로써 기체와 슬러지를 포함하는 물로 분리처리되고, 이때, 스크러버(20)는 15N㎥/min의 처리능력을 가지는 것이 바람직하다. On the other hand, the water separated in the drying and grinding process 200 by the rotary impact drying and mill 20 contains a gas, some fine powder and water particles, this moisture is supplied to the scrubber 30 By performing the scrubber process 300 is separated into water containing gas and sludge, in this case, the scrubber 20 preferably has a processing capacity of 15Nm 3 / min.

이어서 상기 스크러버공정(300)에서 분리된 슬러지를 포함하는 물은 1.5Ton/h의 용량으로 배출되어 하수처리장에서 정화처리되고, 기체는 15N㎥/min으로 악취제거기(40)에 공급되어 악취제거공정(400)을 수행하게 되며, 이 악취제거공정(400)을 통해 정화되어 대기로 방출되는 것으로, 정화처리는 오존 및 플라즈마 처리하여 기체의 방출시 악취를 제거함과 동시에 대기의 오염을 방지할 수 있도록 한다.Subsequently, the water containing the sludge separated in the scrubber process 300 is discharged at a capacity of 1.5Ton / h and purified in a sewage treatment plant, and the gas is supplied to the odor remover 40 at 15 Nm3 / min to remove the odor. 400 to be carried out, and to be purified and discharged to the atmosphere through the odor removal step 400, the purification treatment is ozone and plasma treatment to remove odors during the release of gas and at the same time to prevent pollution of the atmosphere. do.
