Abstract

The invention provides a device for photocatalytic treatment of heavy metal-containing wastewater. The device for photocatalytic treatment of the heavy metal-containing wastewater comprises a reactiontank, a box cover arranged at the top of the reaction tank, and a first water pump, wherein the bottom of the first water pump is fixed to the top of the box cover. The device for photocatalytic treatment of the heavy metal-containing wastewater has the following advantages: the oxygen content in the wastewater is increased, and sufficient oxygen content in the wastewater is guaranteed, so that the oxygen demand in a photocatalytic reaction is guaranteed, and reaction efficiency and purification quality are improved; uniformity of ultraviolet light irradiation and uniformity of the photocatalytic reaction are guaranteed, the reaction rate of the photocatalytic reaction is increased, uniformity of the reaction is guaranteed, the purification quality and the purification effect are improved, the content of heavy metals in the wastewater is reduced to the maximum extent, purification quality of heavy metal sewage is guaranteed, and the standard of safe emission is reached; and impuritiescan be easily collected and cleaned, so that a guarantee is provided for normal operation of equipment.

Description

technical field [0001] The invention relates to the technical field of heavy metal wastewater treatment equipment, in particular to a device for photocatalytically treating wastewater containing heavy metals. Background technique [0002] With the continuous development of society and the continuous development of industry, heavy metal pollution is becoming more and more serious. Not only rivers are polluted and affected, but even people's living and living water are seriously affected. Heavy metal wastewater refers to mining, machinery manufacturing, chemical industry, electronics, Heavy metal-containing wastewater discharged from industrial production processes such as instruments. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans. Process-related, heavy metals in wastewater generally cannot be decomposed and destroyed, but can only be transfer...
