Water treatment device and method capable of improving ozone utilization rate

Abstract

The invention discloses a water treatment device and method capable of improving the ozone utilization rate. The device is characterized in that: a water inlet tank is connected with a water inlet ofan ozone catalytic oxidation reactor through a pipeline provided with a water inlet pump; the ozone catalytic oxidation reactor is internally provided with catalyst filler; a gas distribution pipe isarranged at the bottom part in the ozone catalytic oxidation reactor below the catalyst filler; the gas distribution pipe is connected with an ozone generator through a gas inlet pipe; a water outletof the ozone catalytic oxidation reactor is connected with an output water collection tank through a pipeline; the output water collection tank is connected with a reflux port of the ozone catalytic oxidation reactor through a reflux pipeline provided with a reflux pump; an exhaust opening of the ozone catalytic oxidation reactor is connected with a waste gas collection tank. According to the device disclosed by the invention, water flow in the ozone catalytic oxidation reactor is adjusted to wave flow type flowing, so that a flowing path of water flow in the reactor is greatly increased, so that ozone, a catalyst and sewage are in more sufficient contact; output water is refluxed to be subjected to circulating treatment, so that the utilization rate of the ozone is effectively improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water treatment device and method for improving the utilization rate of ozone. Background technique [0002] my country's water environment is facing the problem of water resource shortage and serious pollution, especially industrial wastewater due to its complex sewage composition, more refractory organic matter, and large chroma, conventional sewage treatment methods are not effective in treating it. Biological methods and biological methods combined with physical methods are facing more and more challenges, so it is urgent to find an effective method and device for treating industrial wastewater. [0003] Ozone is a highly oxidizing gas. It has the advantages of fast decomposition and strong oxidation selectivity. It has been widely used in advanced sewage treatment. Ozone mainly plays the role of decolorization, sterilization and oxidation in sewage treatment. Ozone passes th...
