Abstract
Description
Technical Field
[0001] This utility model relates to the field of reclaimed water treatment technology, and specifically to a reclaimed water process system. Background Technology
[0002] Selection of Reclaimed Water Treatment Processes. Different water quality requirements necessitate different treatment processes. The optimal reclaimed water reuse treatment process can only be determined by comprehensively considering economic and technical parameters, based on the wastewater quality and quantity requirements, as well as the reuse water quality and quantity requirements. It is understood that when high-quality mixed wastewater or wastewater is used as the raw water for reclaimed water, the concentration of organic matter in the water is low, and the treatment objective is mainly to remove suspended solids and small amounts of organic matter from the raw water. A process primarily based on physiochemical treatment, or a process combining biological and physiochemical treatment, can be adopted. When the reclaimed water contains fecal wastewater, the concentration of organic matter or suspended solids in the raw water is high, and the treatment objective is to remove both organic matter and suspended solids simultaneously. A process combining two-stage biological treatment and physiochemical treatment is recommended. When using secondary treated effluent from urban wastewater treatment plants as the source of reclaimed water, a deep treatment process combining physiochemical treatment and biological treatment is preferable.

[0005] Furthermore, a stirring and aeration device is also installed in the domestic sewage regulating tank.
[0006] Furthermore, a hair collector is connected in series on the pipeline from the booster pump to the MBR reactor.
