Modular system for storm water and/or waste water treatment

摘要

The waste water/storm water treatment system includes a plurality of treatment modules, each of which includes upper and lower tank members. Each tank includes an inlet with a spray bar at the upper end thereof, and a drainage member at the lower end thereof. Treated water moves from the drainage member in the upper tank through an inlet at the top of the lower tank. The outlet member of the lower tank is connected to a pump which is controlled by a switch, to move water to the next module in the system or to the drainage system. The tanks have metal-adsorbing inorganic media or agricultural media positioned therein, such as activated rice hulls, corn cobs and the like for adsorbing metals in the storm water/waste water.

主权项

1. A system for treatment of storm water and/or waste water to remove metals therein, comprising:
at least one vertically oriented treatment module which includes at least two tank members, comprising an upper tank member positioned on top of a lower tank member, wherein each module includes a connecting line assembly from an outlet of a upper tank to an inlet of the lower tank therebeneath, wherein each tank member has an inlet near a top thereof, and an inlet member connected to the inlet positioned interiorly of the tank member for releasing storm water and/or waste water into the tank members, a drainage member at the bottom of the lower tank member, and pump actuated by a switch to move treated water from the drainage member of the lower tank member in accordance with the level of water in the lower tank member; and treatment media material present in the upper and lower tank members for adsorbing metals from the storm water and/or waste water which passes through the tank members by gravity or pump action.
