Abstract

The invention relates to an oily sewage purifying device based on photocatalysis and electrolysis technologies. The device comprises a water inlet, a water outlet, a sewage purifying tank, a fluid pipeline, a gas pipeline, a drain pipeline, a heat exchanger, a water tank and a power supply facility, wherein the sewage purifying tank adopts a cylindrical casing; and a front cover and a rear cover are respectively arranged in front and rear of the sewage purifying tank, which are easy to mounted, dismount and move. A circular photocatalysis plate with a porous structure on the surface, an annular ultraviolet tube and an electrode are arranged inside the device. The device combines a photocatalysis technology and an electrolysis technology, can effectively purify organic substances in sewage and inactivate microorganisms, such as bacteria and virus, in the sewage, and is good in oily sewage purification effect and high in efficiency.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an oily sewage purification device based on photocatalysis and electrolysis technology. Background technique [0002] With the development of industry, petroleum, petrochemical, steel, coking, gas generation stations, mechanical processing and other industrial sectors discharge a large amount of oily sewage, which endangers the ecological environment and has a negative impact on humans, animals, plants and even the entire ecosystem. The oily substances in the sewage will form an oil film on the water surface after being discharged into the water, which will reduce the dissolved oxygen content in the water, make the water body smelly, and affect the photosynthesis of algae and the growth of other aquatic organisms in the water. For organisms in the water body such as fish, the oil stain attached to the gills will cause the fish to suffocate and die. If it is directly discharged in...
