Hotel wastewater treatment technology and process

Hotel wastewater must first pass through the grease trap. Then this process is varied.

More common:

Hydrolytic acidification-oxidation ditch or biological contact oxidation or other oxygen-consuming processes-inclined plate sedimentation tank-coagulation filtration (quartz sand)-activated carbon-disinfection-effluent.

Or add dissolved air flotation before hydrolytic acidification process (some do).

If the effluent is not strict with ammonia nitrogen and phosphorus indicators, the above will do.

Otherwise, ammonia nitrogen needs to be removed by reflux, or anaerobic phosphorus removal, or chemical phosphorus removal with coagulant.
