Abstract

The invention discloses a sewage treatment device and a sewage treatment method, and relates to the technical field of environmental protection. A primary reaction device comprises a strong rotationalflow area and an ascending area positioned above the strong rotational flow area; the strong rotational flow area is provided with a micro-bubble inlet, and the micro-bubble inlet is used for being connected with a micro-bubble generator; and a first rotational flow cylinder for enabling the micro-bubbles to form rotational flow is arranged in an inner cavity of the strong rotational flow area. The ascending area is provided with a gas-liquid phase input end and a gas-liquid phase output end, and an ascending channel which is used for gas-liquid phase up-down circulation and is catalyticallyoxidized by a filled catalytic filler is formed between the two ends. According to the sewage treatment device, device-based and closed operation of sewage treatment is achieved, the problem of secondary pollution is avoided, the strong rotational flow area adopts a rotational flow microbubble catalytic oxidation technology, the contact area of oxidizing gas and sewage is increased, and a good treatment effect is achieved on the basis that the reaction time is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage treatment device and a method thereof. Background technique [0002] At present, there are huge challenges in sewage treatment, especially in the field of industrial sewage treatment, which has large discharge volume, complex water quality, high toxicity, and difficult COD degradation. The traditional biochemical degradation process is difficult to deal with, and it is difficult to meet the emission standards. In this regard, many enterprises have adopted advanced oxidation technology (such as ozone catalytic oxidation technology) for pretreatment or advanced treatment of sewage. However, the traditional process has the disadvantages of low utilization rate of ozone, uneven contact between ozone and sewage, resulting in high energy consumption and poor technical effect. [0003] Patent application CN104003504A discloses an ozone catalytic oxidation tre...
