Abstract

본 발명은 다량의 미세한 기포(공기방울)를 인위적으로 발생시키고 이 기포를 폐수처리장치로 공급하여 이 기포가 불순물 표면에 포집하게 하여 이 기포의 부력으로 포집된 불순물을 폐수수면으로 부상시켜 적치된 불순물 포말을 제거하므로서 폐수처리를 하도록 하는 폐수처리방법 및 장치에 대한 것으로서, 종래에도 용존 공기부상(DAF)에 의한 폐수처리장치가 있었으나 이 장치는 처리하려는 폐수에 약품을 첨가하는 혼합조를 거쳐 공기와 폐수를 가압펌프로 약 5-7㎏/㎠의 압력으로 가입탱크에 저장하고 이 가압된 폐수를 대기압 상태에 있는 폐수 처리조로 공급하면 대기압 상태의 폐수에서 기포가 발생되고 이 기포가 폐수속의 불순물을 포집하여 기포의 부력으로 불순물을 부상시켜 스키머로 제거하는 장치로 되어있어 가압탱크에서 가압하여 기포를 발생시키기 위해서는 5-7㎏/㎠의 높은 압력이 필요하므로서 용량이 큰 공기 압축장치가 필요하고 부상에 필요한 공기가 폐수속에서의 용해도의 제한 때문에 필요한 공기를 얻기 위하여 부상조에는 많은 폐수가 필요하므로 부상조의 용량이 커야하고 따라서 설치면적이 넓어야 하며 가동비용의 증가, 부대설비의 설치등의 문제점이 있었으나 본 발명은 상기와 같은 문제점을 해결할 수 있도록 표면활성제와 포수제를 혼합한 혼합물로 인위적으로 미세한 기포를 기포발생기에서 임의로 발생시키고 이 미세기포를 폐수처리장치에 지속적으로 공급하여 폐수속의 불순물과 기포가 물리화학적으로 이온결합하게 하여 폐수수면으로 강제부상시키도록 하므로서 비교적 단순한 구조로서 폐수처리 효율을 극대화시킨 미세한 기포를 이용한 폐수처리장법 및 장치에 대한 발명이다.In the present invention, a large amount of fine bubbles (air bubbles) are artificially generated, the bubbles are supplied to a wastewater treatment apparatus, and the bubbles are collected on the surface of the impurities, so that the impurities captured by the buoyancy of the bubbles float up to the surface of the wastewater The present invention relates to a wastewater treatment apparatus and method for treating wastewater by removing impurity foam and conventionally includes a wastewater treatment apparatus using dissolved air floating (DAF) And wastewater are stored in a sub tank at a pressure of about 5-7 kg / cm 2 by a pressurizing pump, and the pressurized wastewater is supplied to a wastewater treatment tank at atmospheric pressure, air bubbles are generated in the atmospheric pressure wastewater, And the impurities are lifted by the buoyancy force of the bubbles and removed by the skimmer, It is necessary to have a high capacity air compressor so that a high pressure of 5-7 kg / cm 2 is required. In order to obtain necessary air due to limitation of solubility in the wastewater, a large amount of wastewater is required in the float tank However, in order to solve the above problems, the present invention has been made to solve the above-mentioned problems by artificially introducing a mixture of a surfactant and a catching agent The microbubbles are randomly generated in the bubbler and the fine bubbles are continuously supplied to the wastewater treatment device to impregnate impurities and bubbles in the wastewater physically and chemically to the surface of the wastewater so that the wastewater treatment efficiency is relatively simple Wastewater treatment using maximized bubbles The invention for the device.
