摘要： A wetland bioreactor treatment cell for use in a waste water treatment process for reducing stated water quality indicators of the waste water is provided. The wetland bioreactor treatment cell comprises a vegetated containment area containing porous media for receiving an influent comprising water and organic waste material with the containment area having a front end and a rear end. A manifold distributor structure for receiving and distributing the influent into the containment area is provided with the manifold distributor structure being positioned entirely within the front end of the containment area and the manifold distributor structure having a port for allowing cleaning or maintenance of the manifold distributor structure. A hydraulic upflow structure is positioned nearingly adjacent and downstream from the manifold distributor structure with the hydraulic upflow structure maintaining a substantial amount of suspended solids in the front end of the containment area. At least one small hydraulic upflow structure is positioned between the manifold distributor structure and the rear end of the containment area. A hydraulic level control structure is positioned entirely within the rear end of the containment area.

摘要： A method for the step-wise reduction of biological oxygen demand of a waste material having a high concentration of organic waste is provided. The method comprises the steps of providing waste material having a biological oxygen demand and allowing the waste material to separate into a liquid fraction comprising water and suspended organic waste, and allowing at least a portion of the organic waste to be anaerobically digested by microorganisms naturally occurring in the organic waste. Next, at least a portion of the liquid fraction having a reduced biological oxygen demand in relation to the biological oxygen demand of the waste material is removed and mixed with aerobic microorganisms and an aerating gas and allowing at least a portion of the organic waste in the aerobic mixture to be aerobically digested by the aerobic microorganisms to form a liquor comprising water and suspended solids. The liquor has a reduced biological oxygen demand relative to the biological oxygen demand of the liquid fraction. Then, at least a portion of the suspended solids in the liquor is allowed to settle, forming a clarified liquor having a reduced biological oxygen demand relative to the biological oxygen demand of the liquor. The clarified liquor is subjected to microzone treatment to remove at least a portion of the aerobic microorganisms from the clarified liquor to form a permeate having a reduced biological oxygen demand relative to the clarified liquid. Finally, at least a portion of the permeate is discharged or reused.
