Industrial Wastewater Microwave Electrodeless UV Photocatalysis-Double Membrane Separation Coupling Treatment Device

Abstract

The present invention is an industrial waste water microwave electrodeless ultraviolet photocatalysis-dual membrane separation coupling treatment device, the device mainly consists of a reactor (1), a membrane separation system (2), a microwave electrodeless ultraviolet light source system (4), an aeration system, and an ozone tail gas decomposition device (7) connected to the reactor, and an inlet and outlet water system, wherein: the upper and lower parts of the reactor are respectively the reaction zone and the aeration zone, which are separated by a water distribution plate (5); the membrane separation system The microwave electrodeless ultraviolet light source system is located in the reaction zone and is separated by a corrugated partition (3); the aeration system is composed of a microporous aeration head (6) and a blower (8), and the microporous aeration head is located in the aeration At the bottom of the zone, the blower sends air to the aeration zone through the air duct. The invention has the characteristics of high reaction rate, complete degradation of organic matter, long-term operation and the like, and has strong operability and high safety. It is suitable for the treatment of refractory organic industrial wastewater, and it is also suitable for sterilization and disinfection in the field of water supply.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to a structural design of a water treatment device coupled with microwave stepless ultraviolet photocatalytic oxidation and membrane separation, which is suitable for advanced treatment and reuse of refractory industrial wastewater such as textile printing and dyeing wastewater. Background technique [0002] With the development of industrial technology, the content of organic pollutants in industrial wastewater is increasing, the types are increasing, and the components are becoming more and more complex, so the treatment is becoming more and more difficult. At the same time, with the increasing environmental pressure in our country, the central and local governments have proposed and formulated more and more stringent discharge standards for industrial discharge. The research and development of advanced treatment technology and equipment for indu...

Problems solved by technology

Generally speaking, there are mainly the following disadvantages: because the light source used is a traditional electrode-based ultraviolet light source, its structural design is more complicated, the life of the light source is short, the spectral radiation is uneven, and a specially designed light source cooling system is required Cooling it consumes more energy; the other is that the previous patents are a simple integration of photocatalysis and membrane separation, which does not reflect the significance of coupling, so it will inevitably affect its economic efficiency
