Wastewater treatment system and method

摘要

Disclosed is a system and method for treating municipal and sanitary wastewater. The system includes a three-output axial-flow type separator that separates wastewater into at least three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant combination capable of being mechanically dewatered without intermediary biological-process systems. The system advantageously simplifies municipal and sanitary wastewater treatment by potentially eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.

1. A system for treating sanitary wastewater, comprising:
a three-output axial-flow type separator including a first outlet port discharging a lighter-than-water solids stream, a second outlet port discharging a heavier-than-water solids stream, and a third outlet port discharging a partially clarified water stream; a mechanical sludge-dewatering device; the lighter-than-water solids stream and the heavier-than-water solids stream in combination creates a combined stream that feeds the mechanical sludge-dewatering device; and the combined stream having a solids concentration capable of feeding the mechanical sludge-dewatering device without intermediary biological-process systems.
