Problems solved by technology

However, this technology requires a large water flow rate (generally above 30m/h), so it needs to consume a large amount of power, which increases the operating cost of the system
Moreover, with the long-term operation of the system, the generated iron sludge is constantly wrapped on the surface of the carrier particles, which makes the particle size of the carrier continue to increase. If it is

Abstract

The invention relates to a semi-fluidized bed type Fenton oxidation wastewater treatment device. The device is sequentially provided with a stirring-mixing region, a semi-fluidized bed reaction region, a radiation-flow settlement region, a filler reaction region and a baffling semi-range settlement region. According to the device, the semi-fluidized bed reaction region and the filler reaction region are arranged, and a Fenton catalyst and an iron-carrying 3A molecular sieve catalyst are respectively utilized as fillers; a semi-fluidized bed has high transmission efficiency, and the problem ofloss of the catalyst can be effectively avoided; and a 3A-molecular sieve filler is wide in pH application range and has efficient catalytic efficiency to degradation-resistant organic matters. The device has the advantages of simple structure, easiness in operation, good treatment effect and the like and can be conveniently arranged in each stage of the water treatment flow.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a novel Fenton reaction device for pretreatment of industrial sewage and advanced treatment of biochemical tail water. Background technique [0002] Fenton oxidation is an effective oxidation water treatment process, which is widely used in the field of sewage treatment. The main principle is that under acidic conditions, ferrous iron is used as a catalyst to oxidize organic matter in water by the strong oxidative hydroxyl generated when it interacts with hydrogen peroxide. Fenton oxidation has the characteristics of rapidity, high efficiency, simple and flexible operation, and mild reaction conditions. In the field of advanced wastewater treatment, it is mainly used to treat biochemical effluent and remove residual refractory organic matter in the water. Therefore, Fenton oxidation has become one of the important methods to achieve standard discharge or reuse of wastewater. ...
