Problems solved by technology
[0004] The traditional suspended phase photocatalytic system commonly used in the laboratory has certain limitations, which are specifically manifested in: (1) It is difficult to recycle and reuse the suspended semiconductor photocatalytic particles, which not only increases the cost of the catalyst, but also easily causes secondary pollution
(2) Suspended semiconductor photocatalyst particles in the solution have the effect of reflecting a large amount of incident light, and the light utilization rate is greatly reduced

An immobilized photocatalytic thin film reactor comprises a circulating device, an ultraviolet lamp tube, a reactor support, a temperature control device, a glass carrier plate and a catalyst carrier.A liquid storage tank, a beaker, a magnetic circulation pump, a rotor flowmeter and a liquid distribution pipe of the circulating device are connected in turn through conduits. The glass carrier plate and the catalyst carrier are placed in the liquid storage tank; a water outlet is arranged on the side face of the liquid storage tank, the water outlet is sleeved with a conduit, and the other endof the conduit is placed in an open port of the beaker; the minimum width of the catalyst carrier is larger than the diameter of the water outlet; the magnetic circulation pump and the temperature control device are located on a same horizontal plane; the ultraviolet lamp tube is arranged on the top of the reactor support, and the liquid storage tank is located at the bottom of the reactor support, and the position of the liquid storage tank is higher than that of the breaker. The catalyst makes full contact with a reaction solution, the photocatalytic efficiency is high and the stability is good; the filtering and recycling steps of the catalyst are omitted, and the operation cost of experiments can be saved. The temperature control device and the rotor flowmeter can be used for investigating the influence of the solution temperature and the solution circulation flow velocity on the photocatalytic effect.
Description
technical field [0001] The invention belongs to the technical field of chemical devices, and relates to a photocatalytic reactor capable of fixing a catalyst and circulating and degrading waste water. Background technique [0002] With the rapid increase of population and the rapid development of industrial scale in our country, tens of thousands of tons of waste water are discharged into rivers without treatment, seriously endangering the ecological environment of people's daily life. Wastewater treatment has become a hot topic in the field of environmental protection. Among them, azo dye wastewater has the characteristics of large water volume, complex water quality and deep color, and has become one of the more difficult industrial wastewater to treat. Due to the toxicity and carcinogenicity of azo dyes, it is difficult to remove them by general biochemical and chemical oxidation methods. [0003] Advanced oxidation technology is a method of using strong oxidative free r...
