Description

하수 및 오·폐수 처리장치{Sewage and wastewater treatment equipment}Sewage and wastewater treatment equipment

본 발명은 하수 및 오폐수 처리장치에 관한 것으로 보다 구체적으로는 슬러지의 처리가 용이하고, 유지 관리에 따른 비용을 절감할 수 있게 한 하수 및 오폐수 처리장치에 관한 것이다.
The present invention relates to a sewage and wastewater treatment apparatus, and more particularly, to a sewage and wastewater treatment apparatus which makes it easier to treat sludge and reduces the cost of maintenance.

일반적으로 하수나 오·폐수(이하 유입수라 한다)에 존재하는 오염물질은 물리적, 화학적 또는 생물학적 방법에 의해 처리되고 있는데 그 중 폐수에 용해되어 있는 유기물질을 미생물세포의 먹이로 흡수시켜 미생물의 성장에너지로 사용함으로써 유기물질의 농도를 감소시키고 미생물의 농도를 증가시킨 후 증가한 미생물은 침전지에서 고액 분리 후 처리하는 생물학적 처리 방법은 미생물 성장 방식에 따라 부유식과 부착식으로 구분할 수 있으며 산소이용 여부에 따라 호기성처리, 혐기성 처리로 구분할 수 있다.
In general, pollutants present in sewage or wastewater (hereinafter referred to as influent) are treated by physical, chemical or biological methods. Among them, organic matter dissolved in wastewater is absorbed into the food of microbial cells to grow microorganisms. The biological treatment method that reduces the concentration of organic substances by using energy and increases the concentration of microorganisms and then increases the concentration of microorganisms after solid-liquid separation from the sedimentation basin can be classified into floating and adhesive types according to the growth method of microorganisms. It can be divided into aerobic treatment and anaerobic treatment.

한편, 생물학적 방법에 의한 종래의 하수나 오·폐수 처리 장치는 유입수에 포함되어 있는 큰 입자의 부유물질을 제거하는 비중분리조와, 오염물질의 농도와 유량을 조정하는 유량조정조와, 오염물질의 침전을 유도하는 1차침전조와, 공기를 폭기시켜 미생물 접촉여재에 미생물을 접촉시킴으로써 미생물로 하여금 유입수에 함유되어 있는 유기성 오염물질을 영양성분으로 하여 증식하면서 자기 소화작용으로 분해되게 하는 호기조와, 증식된 미생물덩어리는 침전시키고 상등액에 해당되는 처리수는 처리수조에 보내고 2차적으로 침전된 활성오니의 일부는 호기조에 반송하는 2차침전조와, 처리수를 일정 시간 동안 저장하였다가 최종적으로 소독한 다음 방류하는 방류조로 구성된다.
On the other hand, conventional sewage and wastewater treatment apparatuses by biological methods include specific gravity separation tanks for removing large particles of suspended solids contained in influent, flow rate adjustment tanks for adjusting the concentration and flow rate of pollutants, and precipitation of pollutants. A first settling tank which induces aeration, and an aerobic tank which causes the microorganisms to decompose by self-extinguishing while proliferating organic contaminants contained in the influent as nutrients by contacting the microorganisms with the microorganism contact medium by aeration of air. The microbial mass is precipitated and the supernatant is sent to the treatment tank, and the secondary sludge is returned to the aerobic tank. It consists of a discharge tank.

그러나 상기와 같은 종래의 처리 장치는 모든 공정이 독립적으로 설치된 처리조 내부에서 개별적으로 이루어지기 때문에 각 공정에 해당하는 처리조가 차지하는 면적이 커서 처리 장치의 설치를 위한 부지 매입 비용이 증가하는 문제점이 있을뿐만 아니라, 각 처리조의 건설에 따른 시간과 비용도 증가하는 문제점이 있었다.However, the conventional treatment apparatus as described above has a problem in that the land purchase cost for the installation of the treatment apparatus is increased because the area occupied by the treatment tank corresponding to each process is large because all the processes are made separately in the treatment tank installed independently. In addition, there was a problem that increases the time and cost according to the construction of each treatment tank.

또한, 각 공정을 수행하기 위한 각각의 처리조가 독립적으로 설치되어 운전되기 때문에 각 처리조의 운전에 따른 유지 및 보수관리비가 증가하여 경제성이 떨어지는 문제점이 있었다.
In addition, since each treatment tank for performing each process is installed and operated independently, there is a problem that the economical efficiency is lowered by increasing the maintenance and maintenance management costs according to the operation of each treatment tank.

본 발명은 위와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로서, 본 발명의 목적은 연속되는 공정의 처리조를 일체화하고, 침전조의 효율성을 향상시킴과 동시에 호기조의 전후에 별도의 여재실을 형성하여 미생물에 의한 처리 능력을 향상시킴과 동시에 호기조의 용량을 감소시켜 호기조의 유지 관리에 따른 비용을 절감할 수 있게 한 하수 및 오·폐수 처리장치를 제공하는 데 있다.
