Abstract
A wastewater treatment system is disclosed which can be used to treat high-strength septage, sewage and industrial wastewater. The wastewater treatment system consists of three major components. In the first component, solids are separated from the liquid component of the wastewater being treated. The separated solid portion is removed to a composting component wherein it is turned into a commercially useful compost material. The liquid component is subjected to a two part treatment wherein the first part of the treatment is carried out in a sequencing batch reactor and the second part is carried out in at least one reed bed. In an alternative embodiment of the present invention, the various components of the wastewater treatment system are in modular form.
