ABSTRACT:
A subsurface flow constructed wetland treats a variety of flowing wastewater effluents, provides pre-treatment clog-reducing wastewater sludge disintegration, and adds pre-treatment nutrients to wastewater so as to enhance microbial growth therein for improving the effectiveness and efficiency of wastewater treatment. The constructed wetland includes a wastewater treatment system having a flow intake, a pre-treatment nutrient addition chamber, and a wastewater flow divider. The flow divider further has a compressed air aerator in the bottom thereof. The constructed wetland includes one or more treatment cells having a soil, fine stone, organic and/or synthetic material substrate cap covering a further substrate media accommodating the wastewater to be treated. The substrate cap is populated by natural plants having root systems extending within the substrate. The plant root systems extend from the substrate downward into the wastewater being treated, and the roots serve to physically and/or biologically mediate the removal of undesirable components from the wastewater so as to cleanse and thus treat the wastewater. The constructed wetland includes a treated water discharge conduit for discharging the flowing water into a desired after treatment water utilization modality, such as to discharge to the ground or to a body of water.
