A rotary drum type photo-catalytic reactor for treating sewage is composed of a water bath with water inlet and outlet, a rotary drum arranged horizontally in said water bath by a supporting frame and with coated TiO2 photo-catalyst layer on its inner surface, a speed adjustable motor for driving said rotary drum via gear set, and an ultraviolet lamp able to irradiate the inner surface of rotary drum by a certain angle.
Description
technical field [0001] The invention relates to a photocatalytic water treatment reaction device. Background technique [0002] Photocatalytic water treatment technology is moving from laboratory to practical application due to its wide applicability and high efficiency. At this time, reactor design has become an important link in whether this technology can be industrialized. The photocatalytic water treatment reactor integrates the light source, catalyst and treatment liquid, and can make it a place to maximize the photocatalytic reaction to treat sewage. Therefore, it should have the ability to fully contact the catalyst, treatment liquid, and photons. basic features. High treatment intensity, low treatment cost and wide adaptability are the basic requirements for photocatalytic water treatment reactors. [0003] At present, there are two main types of photocatalytic water treatment reactors: one is a fixed-bed reactor (including a membrane reactor) that loads a cataly...
