Problems solved by technology

[0005] Secondly, there is no uniform evaluation standard and specification for the catalytic activity of the composite catalytic reaction. The devices designed by different researchers vary greatly, and the evaluation methods are different. The experimental results of different laboratories are not comparable, so many researchers have to do a lot of repetitive work. , thus affecting the development of water treatment technology, therefore, it is urgent to develop a new type of composite catalytic reactor to achieve precise control of the reaction, high-efficiency reaction and instant evaluation

Embodiment Construction

[0025] The present invention is a novel device for the research of photocatalytic and enzyme-catalyzed composite catalytic reactions, including a cylindrical catalytic reactor 1, a magnetic stirrer 2, a tubular ultraviolet light source 3, a cylindrical light-shielding outer cover 4, and a membrane pressure ring Kit 5 and cylindrical perforated light shield 6. The catalytic reactor 1 is a cylinder with a flat bottom and an upper opening, and is placed on a magnetic stirrer 2 to achieve uniform dispersion of the dissolved matter in the reactor. Eight ultraviolet lamp tubes are vertically distributed around the cylinder of the catalytic reactor 1 as the ultraviolet light source 3, and a cylindrical light-proof cover 4 is added outside the ultraviolet light source 3 to prevent short-wave ultraviolet light from harming people. Insert the connected membrane pressure ring set 5 and the porous light shield 6 inside the catalytic reactor 1 . Membrane pressure ring set 5 is inserted ve...

Description

technical field [0001] The device of the invention relates to a device for researching photocatalytic and enzyme-catalyzed composite reactions, and is mainly used for evaluating photocatalytic and enzyme-catalyzed composite activities and studying kinetics of degradation pollutants. Background technique [0002] Chlorophenols are a class of refractory compounds that have been widely used in the production of wood preservation, insecticides, herbicides, pesticides, fuels and plasticizers for a long time. Its production wastewater is very poisonous, has a strong denaturing effect on biological tissues, strongly stimulates the skin and mucous membranes, and is corrosive. The toxicity of chlorophenol increases with the increase of its chlorination degree, and it is difficult to degrade. The United States, China and other countries have included it in the "blacklist" of harmful substances or priority pollutants in water. Therefore, how to eliminate the pollution of chlorophenol...
