Abstract
본 발명은 난분해성 고농도 폐수의 처리효율을 증진시키는 공정에 관한 것이다.The present invention relates to a process for enhancing the treatment efficiency of highly degradable high concentration wastewater.
고농도 나분해성 폐수를 기존의 활성 슬러지공법과 같이 반송슬러지를 폭기조에만 공급하여 미생물에 의한 분해가 폭기조에서만 대부분 이루어지는 공법에서는 좋은 처리효율을 기대하기 어렵다. 이러한 고농도, 난분해성 폐수의 분해효율을 높이고자 기존의 집수조에 반송슬러지를 반집수조에서 생물학적 처리가 가능하게 한 공정이다.It is difficult to expect good treatment efficiency in a method where the high concentration of degradable wastewater is supplied only to the aeration tank, as in the conventional activated sludge method, so that decomposition by microorganisms is mostly performed in the aeration tank. In order to increase the decomposition efficiency of such a high concentration, hardly degradable wastewater, it is a process that enables the biological treatment of the return sludge in the semi-collecting tank.
본 발명의 가장 큰 특징은 미생물에 의한 분해가 기존의 공법에서는 폭기조 한 곳에서만 이루어지는 것에 반하여 본 발명에서는 집수조와 유동충 생물막법의 두 곳에서 이루어지므로 고농도 난분해성 폐수의 처리효율을 증대시킬 수 있으며, 또한 기존의 설비인 집수조를 사용하므로 별도의 부지나 비용이 소요하지 않으면서 처리효율을 증대시킬 수 있다는 점이다.The biggest feature of the present invention is that the decomposition by microorganisms is performed in only one place of aeration tank in the conventional method, and in the present invention, since it is made in two places of the sump tank and the fluidized bed biofilm method, it is possible to increase the treatment efficiency of high concentration hardly degradable wastewater. In addition, it is possible to increase the treatment efficiency without using a separate site or cost because it uses the existing collection tank.

본 발명은 난분해성 고농도 폐수의 처리효율을 증진시키는 공정에 관한 것이다. 고농도 난분해성 폐수를 기존의 활성슬러지공법과 같이 반송슬러지를 폭기조에만 공급하여 미생물에 의한 분해가 폭기조에서만 대부분 이루어지는 공법에서는 좋은 처리효율을 기대하기 어렵다. 이러한 고농도, 난분해성 폐수의 분해효율을 높이고자 기존의 집수조에 반송슬러지를 반송시켜 주며 적정한 양의 영양제(요소, 인산)를 투여함으로써 전처리 설비인 집수조에서 생물학적 처리가 가능하게 한 공정이다.The present invention relates to a process for enhancing the treatment efficiency of highly degradable high concentration wastewater. It is difficult to expect good treatment efficiency in a method in which a high concentration of hardly degradable wastewater is supplied only to the aeration tank by supplying the return sludge to the aeration tank as in the conventional activated sludge method. In order to increase the decomposition efficiency of the high concentration and hardly degradable wastewater, the return sludge is returned to the existing water collection tank and biological treatment is possible in the water collection tank, which is a pretreatment facility, by administering an appropriate amount of nutrients (urea and phosphoric acid).
본 발명의 가장 큰 특징은 미생물에 의한 분해가 기존의 공법에서는 폭기조 한 곳에서만 이루어지는 것에 반하여 본 발명에서는 집수조와 유동층 생물막법의 두 곳에서 이루어지므로 고농도 난분해성 폐수의 처리효율을 증대시킬 수 있으며, 또한 기존의 설비인 집수조를 사용하므로 별도의 부지나 비용이 소요하지 않으면서처리효율을 증대시킬 수 있다는 점이다.The biggest feature of the present invention is that the decomposition by the microorganism is performed only in one place of aeration tank in the conventional method, and in the present invention, since it is made in two places of the collection tank and the fluidized bed biofilm method, it is possible to increase the treatment efficiency of high concentration hardly degradable wastewater. In addition, since the existing water tank is used, treatment efficiency can be increased without requiring a separate site or cost.
이하, 본 발명의 구체적인 실시예를 도시하여 첨부된 도면에 의하여 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[실시예]EXAMPLE
백상지 제지 폐수의 경우 생물학적 처리시 난분해성 물질인 LATEX성분을 함유하고 있다. 이러한 폐수의 처리효율을 높이고자 제1도에 나타난 바와 같은 과정을 통하여 처리하였다.Woodfree paper wastewater contains LATEX, a biodegradable substance during biological treatment. In order to improve the treatment efficiency of such wastewater was treated through the process shown in FIG.
집수조(1)에 LATEX를 함유한 폐수가 유입되며(1-a); 요소, 인산으로 이루어진 미생물의 성장에 필요한 영양제가 유입되고(1-b); 폭기(aeration)를 위한 공기가 유입되고(1-c); 침전조(4)에서 반송된 반송슬러지가 유입된다(4-a); 이러한 공정을 통하여 집수조(1)에 형성된 미생물에 의해 LATEX를 함유한 폐수의 1차적 분해가 이루어지며 FLOC이 형성되어; 유동층 생물막법 유동조(2)에 유입된다.Wastewater containing LATEX is introduced into the sump (1) (1-a); Nutrients required for the growth of microorganisms consisting of urea and phosphoric acid are introduced (1-b); Air for aeration is introduced (1-c); Conveying sludge conveyed from the settling tank 4 flows in (4-a); Through this process, primary decomposition of wastewater containing LATEX is made by the microorganisms formed in the sump 1 and FLOC is formed; It flows into the fluidized-bed biofilm flow tank (2).
집수조에서 처리되지 않은 LATEX와 유기물, 무기물은 본 공정에 9의해 최종 분해가 이루어지며; 화학반응 응집조(3)에서 화학적 응집처리에 의하여 FLOC이 형성되고; 다음 공정인 침전조(4)로 유입되어 처리수(4-c)는 상등수로 유출되며 여기서 발생된 슬러지(sludge)는 일부는 폐슬러지(4-b)로 방출되고 일부는 집수조(4-a) 및 유동층 생물막법 유동조(2)로 반송되어 진다.Untreated LATEX, organics and inorganics in the sump are final decomposed by this process; FLOC is formed by chemical flocculation in the chemical reaction flocculation tank 3; The next process is introduced into the settling tank 4, and the treated water 4-c is discharged to the supernatant, and the sludge generated therein is partially discharged into the waste sludge 4-b and some is collected in the sump tank 4-a. And the fluidized bed biofilm method flow tank 2.
이상과 같이 본 발명은 백상지 제지공정의 도피(coater)공정에 투입되는 LATEX성분을 함유한 폐수의 유동층 생물막법 처리시 별도의 부지나 시설없이 그 효율을 현격히 증대시킬 수 있다.As described above, the present invention can significantly increase the efficiency of the wastewater containing LATEX component which is put into the coater process of the white paper making process without any additional site or facility.
