To provide a waste water treatment apparatus for solving a problem that waste water discharged from a dental chair unit at any time during medical treatment is danger of being contaminated with patient's pathogens, thereby, in the case the waste water is discharged to the outside directly through a drain pipe, causing an environmental pollution problem.
Waste water discharged from the terminal discharge opening of individual dental chair units is stored in a sterilizing chamber. The chamber is equipped with an acidic water-generating electrode and generates acidic water directly by electrolysis to sterilize the waste water, which is discharged outside. For this purpose, this apparatus is arranged with a controller that controls the processes based on water level signals, pH values, the quantity of current applied to the electrode and the like. As a system, a system having a storage tank for temporarily storing waste water, a system for directly introducing waste water, or an overflow system is employed.
