ADVANCED WASTEWATER TREATMENT USING MAGNETIC FORCE AND BIOMEMBRANE

PURPOSE: Provided is an advanced wastewater treatment system using magnetic force and biomembrane. The system can remove efficiently organic matters, phosphorous and other pollutants by using magnetic coagulants, chemical coagulants and magnetic force and also remove nitrogen through denitrification process by cultivation of bacteria. CONSTITUTION: The treatment system is composed of the following main parts: a grit chamber (2) ; a supply facility (7) for magnetic coagulants and chemical coagulants; magnetic flocculation tanks (4,11) to form magnetic flocks after mixing magnetic coagulants with wastewater containing suspended solids; magnetic adsorption tanks (5,12,20) to separate magnetic flocks from treated water; a nitrification tank (15); a denitrification tank (16); a chemical injection tank (9) for mixing rapidly denitrified water with chemical coagulants; a chemical flocculation tank (10) for mixing slowly mixed water to form chemical flocks; and a sterilization tank (17).
