Description

Technical Field

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

[0002] Urban wastewater reuse typically uses secondary treated effluent from urban wastewater treatment plants as raw water. After these two stages of treatment, suspended solids (SS) and boron oxidant (BOD5) in urban wastewater can generally be reduced by more than 90%, resulting in a significant improvement in water quality. However, directly recycling urban wastewater after two stages still fails to meet requirements for many important water quality indicators. Therefore, further treatment of the secondary treated urban wastewater, namely reuse treatment (also known as advanced treatment or tertiary treatment), is a necessary prerequisite for reuse.
