Wastewater Treatment System

摘要

A dual tank wastewater treatment system for performing an extended aeration process to provide a natural, biological breakdown of the organic matter in wastewater using, for example, but not limited to, a continuously operating air pump and diffuser bar system for aeration purposes and a flexible media filter. The air pump used is stronger than conventional air pumps and the diffuser bar is designed to provide more efficient oxygen transfer than conventional diffuser systems by mixing air against the system flow to provide better mixing and longer retention time in the aeration process. The flexible media filter provides a final filtration and polishing of the effluent before it passes through a flow equalization apparatus and exits the system.

主权项

1. A wastewater treatment apparatus comprising:
a first chamber including an inlet opening defined in an inlet wall and a lower chamber portion; a second chamber including an outlet opening defined in an outlet wall and a lower chamber portion; a common wall between said first and second chambers, the common wall having a bottom opening in a lowermost portion and the common wall bottom opening providing immediate and direct fluid communication between the lower chamber portion of the first chamber and the lower chamber portion of the second chamber; a diffuser bar assembly having a substantially rectangular shape with a length about 4 times a width of the assembly and being oriented with the length extending from the inlet wall of the first chamber toward the common wall and the diffuser bar assembly including a plurality of holes spaced substantially evenly around opposite sides of the diffuser bar assembly; a continuously operating air pump being connected to a proximal end of an air line and the air line being in gaseous communication with the diffuser bar assembly; and an outlet filter assembly connected to and in fluid communication with the outlet opening, the outlet filter assembly comprising:
a brush filter assembly including a substantially cylindrical frame element made of two substantially circular plastic end portions being rigidly connected to each other by a plurality of plastic rods and an outlet face side portion having formed therein an outlet line access port, and a plurality of brush rope elements attached to and substantially covering an outer side surface and a bottom of the substantially cylindrical frame element, anda flow equalization apparatus including an upright cylindrical tube having a closed bottom end, an open top end, an outlet tube connected to and extending substantially perpendicularly away from and in fluid communication with the upright cylindrical tube, the outlet tube extending through an outlet line cap attached to an end of an outlet line inside the brush filter assembly and into and in fluid communication with the outlet line, a standard flow port formed in the upright cylindrical tube between the closed bottom end of the upright cylindrical tube and the outlet tube, an elevated flow port formed in the upright cylindrical tube adjacent an open top end of the upright cylindrical tube and above the outlet tube, and a peak flow port being defined by the open top end of the upright cylindrical tube.
