Laundry Wastewater Treatment Method Based on Photocatalytic Reaction

Washing machines, as common household appliances, consume a lot of domestic water. The working process of the traditional washing machine mainly includes washing, rinsing and dehydration. The rinsing water has low pollution level, but the consumption is large, accounting for more than 70% of the total water consumption, and the water resource utilization rate is low. Aiming at this problem, combined with water purification technology, a new carrier structure was designed by using 3D modeling software and the optical path design of the structure was optimized by COMSOL software. A ceramic wastewater based on photocatalytic reaction was fabricated by ceramic 3D printing technology. Processing device. Combining photocatalysis with ceramic 3D printing technology, design a photocatalytic reactor to improve water treatment efficiency, safe and no secondary pollution. Through the standard cloth washing water treatment experiment, it is determined that the pollution component in the laundry wastewater treated by the reactor is reduced, and the purification effect is obvious.
