Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a photocatalytic wastewater treatment tank. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Wastewater treatment often involves photocatalysis, and the principle of photocatalysis is based on the oxidation-reduction ability of photocatalysts under light conditions, which can achieve the purpose of purifying pollutants, synthesizing and transforming substances.

[0003] Existing photocatalytic wastewater treatment ponds suffer from poor light transmittance, resulting in limited light irradiation area within the wastewater. Since light is a prerequisite for photocatalytic oxidation reactions, this leads to decreased wastewater treatment efficiency. Therefore, a new photocatalytic wastewater treatment pond is proposed.
