Description

다공질 여과체와 초음파를 이용한 오,폐수 처리장치Wastewater treatment device using porous filter medium and ultrasonic wave

본 발명은 다공질 여과체와 초음파를 이용하여 오수와 폐수를 여과, 정화하는 오,폐수 처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus for filtering and purifying sewage and wastewater using a porous filter medium and ultrasonic waves.

지금까지의 오,폐수 처리장치는 여과체만을 이용한 여과방법과 원심력과 화공약품 등을 이용한 정화 처리방법 등 여러가지 방법이 있었으나 여과체를 이용한 경우 여러차례 여과로 인한 장시간 소요와 여과체를 자주 교체시켜야 하고 원심력을 이용한 경우 설치 및 처리비용이 많이 들고 화공약품을 사용하는 경우 처리비용증가와 함께 또 다른 환경오염의 원인이 되었다.Until now, there have been various methods of wastewater treatment equipment such as filtration method using only filter medium and purification method using centrifugal force and chemicals.However, when using filter medium, it takes long time due to filtration several times and frequent replacement of filter medium. The use of centrifugal force is expensive to install and treat, and the use of chemicals increases the cost of treatment and is another source of environmental pollution.

본래 산업적으로 이용하는 초음파는 10㎑ 이상의 진동수를 가진 음파로서 진동으로 액체입자를 분산시켜 미세화시키고 공동현상을 이르켜 공동의 표면에 입자들이 붙어서 팽창하여 공동이 폭발할 때 발생하는 폭발에너지로 수중의 입자들을 분쇄시키고 세균의 세포막도 파괴시키는 것으로 본 발명에서는 이러한 초음파를 이용하여 오,폐수를 원통형 다공질 여과체로 고형물질을 걸러낸후 초음파로서 물분자를 미세화 시키므로서 물의 응집력 및 표면장력을 약화시키고 오염물의 결정구조 파괴와 박테리아 등의 세균 세포막을 파괴시켜 여과된 물을 정화시키고 특히 오,폐수를 여과시켜주는 다공질 여과체 내주연에 여과시마다 쌓이는 고형물질을 벤츄리식 역세척수 흡입노즐로 흡입하여 외부로 배출시켜 다공질 여과체를 교환하지 않고 반영구적으로 사용할 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.Originally, industrial ultrasonic waves are sound waves with a frequency of 10 Hz or more, which disperse liquid particles by vibration and make them finer, and reach the cavitation phenomenon. In the present invention, the wastewater is filtered through a cylindrical porous filter using ultrasonic waves, and then the water molecules are refined by ultrasonic waves to reduce water cohesion and surface tension and to determine contaminants. Purify the filtered water by destroying the structure and destroying bacterial cell membranes such as bacteria.In particular, the solid material accumulated every time in the inner circumference of the porous filter medium that filters the wastewater and the wastewater is sucked with a venturi backwash water suction nozzle and discharged to the outside. Semi-permanently without replacing the porous filter medium If it described in detail based on the drawings that can be used as follows.
