The sewage from the bathhouse is a high-quality reclaimed water source with a large amount of water, low pollution level, and convenient for recycling. In order to better utilize water resources and based on geographical environment considerations, bathing wastewater can be treated by simple and economical methods as greening water.

The process flow is as follows:

Bathing wastewater - grid - regulating tank - coagulation reaction tank - coagulation sedimentation tank - intermediate tank - quartz sand filtration - disinfection tank - effluent discharge

Brief description of process flow

The incoming sewage is removed from the large particles through the grid, and then enters the regulating tank for homogenization regulation of water quantity and quality. The sewage is lifted to the coagulation reaction tank by a lift pump, fully mixed with the coagulant and reacted before entering the coagulation sedimentation tank, which adopts a vertical flow sedimentation structure. Because vertical flow sedimentation tanks have the advantages of short settling time, good separation efficiency, and small floor space. The supernatant from the coagulation sedimentation tank overflows to the intermediate tank through an overflow weir, and then the sewage is lifted into a quartz sand filter by a high-pressure water pump. Through the interception, filtration, and adsorption of the filter, most of the SS and other substances are removed. The water from the quartz sand filter enters the disinfection tank and is disinfected using efficient, residue free ozone.

The sludge from the coagulation and sedimentation tank is regularly discharged into the sludge digestion tank through a sludge pump. After a long period of sludge digestion, the final concentrated sludge is transported outward by sanitation vehicles for treatment.
