Description

공장폐수의 용수처리 시스템{A disposal system to water for industrial use of trade water}A disposal system to water for industrial use of trade water}

본 발명은 공장폐수의 용수처리 시스템에 관한 것으로, 더욱 상세하게는 공장에서 발생되어 기존의 폐수처리설비에 의해 수처리된 폐수처리수를 재차 정화처리하여 공업용수로 재사용할 수 있도록 함으로서 상수도를 통해 공급되는 용수량을 최소화시켜 용수비용을 크게 절감할 수 있으면서도, 하수를 통해 방류되는 폐수처리수가 었어 환경오염도 방지할 수 있는 구조를 갖도록 한 공장폐수의 용수처리 시스템에 관한 것이다.The present invention relates to a water treatment system for plant wastewater, and more particularly, to supply the wastewater treated water generated in the plant and treated by the existing wastewater treatment facility to be purified again and reused as industrial water. The present invention relates to a water treatment system of a plant wastewater, which has a structure capable of minimizing the amount of water to be used, and greatly reducing the cost of water, while preventing wastewater from being discharged through the sewage.

일반적으로, 종래의 공장폐수처리 시스템은 공장에서 발생된 폐수를 저정하는 폐수원수저장조와, 상기 폐수원수로부터 공급되는 폐수원수를 침전시켜 폐수원수 중에 포함된 침전 슬러지를 제거하는 침전조와, 상기 침전조를 거쳐 공급되는 폐수원수에 응집제를 첨가하여 폐수내에 포함된 폐유를 응집시켜 수면에 부상시키고, 이러한 부상슬러지를 제거하는 부상조와, 상기 부상조로부터 공급되는 폐수처리수를 일시저장하고 저장된 처리수를 방류하는 처리수조(처리원수조)로 구성되어 있다.In general, the conventional plant wastewater treatment system is a wastewater source storage tank for storing the wastewater generated in the factory, a sedimentation tank for sedimentation sludge contained in the wastewater source by sedimenting the wastewater source water supplied from the wastewater source water, and the settling tank A flocculant is added to the wastewater supplied through the flocculant to flocculate the waste oil contained in the wastewater and float it on the surface, and temporarily store the flotation tank for removing such sludge and the wastewater treatment water supplied from the flotation tank and discharge the stored treated water. It consists of a treatment water tank (process water tank).

그러나 이러한 종래의 공장폐수처리 시스템은 처리수조내에 저장된 페수처리수를 하수구를 통하여 방류하는데 이러한 폐수처리수는 완전 정수처리된 것이 아니라 폐수 중에 포함된 이물질 중 폐유와 무거운 침전슬러지만을 제거시킨 것으로서, 미세 중금속 및 각종 유해 물질이 다량 포함되어 있기 때문에 하천의 오염이 불가피할 뿐만 아니라 공장공정에 사용되는 용수을 상수도를 통해 지속적으로 공급받아 사용하기 때문에 용수사용량이 많아 용수비용이 높음은 물론 폐수처리방류량도 매우 크다는 문제점이 있었다.However, the conventional plant wastewater treatment system discharges the wastewater treated in the treatment tank through the sewer. The wastewater treatment water is not completely purified but removes only waste oil and heavy sedimentation sludge from the foreign matter contained in the wastewater. Because it contains heavy metals and various harmful substances, pollution of rivers is inevitable, and the water used in the factory process is continuously supplied through tap water, so the water usage is high and the waste water treatment discharge is very high. There was a big problem.

본 발명은 상기와 같은 종래의 문제점을 고려하여 안출한 것으로서, 그 목적은 공장에서 발생되어 기존의 폐수처리설비에 의해 수처리된 폐수처리수를 재차 정화처리하여 공업용수로 재사용할 수 있도록 함으로서 상수도를 통해 공급되는 용수량을 최소화시켜 용수비용을 크게 절감할 수 있으면서도, 하수를 통해 방류되는 폐수처리수가 었어 환경오염도 방지할 수 있는 공장폐수의 용수처리 시스템을 제공하는 것이이다.The present invention has been made in view of the conventional problems as described above, the object of the water is to be purified from the wastewater treatment water generated in the factory and treated by the existing wastewater treatment facility to be purified again and reused as industrial water.
