WASTEWATER TREATMENT METHOD AND SYSTEM FOR REMOVAL OF PHOSPHORUS, NITROGEN AND COLIFORMS

摘要

A novel wastewater treatment method, apparatus and system to treat wastewater from septic tanks, including a tertiary treatment for the passive removal of phosphorus, nitrogen and coliforms from sewage streams, is described. The method, apparatus and systems comprise a septic tank, an enviro-septic system, a dephosphatation system, a denitrification system and a polishing field, including related piping distribution and pumping systems. The invention further comprises an enviro-septic system comprising an advanced enviro-septic pipe, a filtration medium, a collection drain and associated distribution systems; a polishing field comprising an advanced enviro-septic pipe, a collection drain, a filtration medium, a collection drain and associated distribution systems; and a dephosphatation system comprising a filtration medium for the removal of phosphorus and coliforms and a denitrification system comprising a filtration medium for the removal of nitrogen. The wastewater treatment method is used to treat domestic, industrial and commercial sewage effluent.
