Method and Apparatus for Advanced Treatment of Sewage and Industrial Wastewater Using Magnetic Force and Biological Film

摘要

In the present invention, organic matter, phosphorus and other contaminants use magnetic flocculant, chemical flocculant, and magnetic force, and nitrogen is treated by using nitrogen removal process by cultivation, so that sewage and wastewater are treated much better than the discharge limit of treated water. It is an object of the present invention to provide an advanced sewage treatment system that enables not only discharge into natural rivers but also reuse.;According to the present invention for achieving the above object, stirring the sedimentation facility for removing contaminants, etc. contained in the inflow sewage, a supply facility for supplying a magnetic flocculant and a chemical coagulant, and a sewage containing the magnetic flocculant and suspended solids After mixing, the magnetic flocculant forms a magnetic floc attached to the surface of the suspended solids, and the magnetic flocculation tank and the adsorption tank separating the magnetic flocs and the treated water, and the treated water separated from the magnetic adsorption tank are nitrified by ion exchange and nitrification. Chemical nitrification and denitrification tanks which are denitrified by denitrification bacteria, and chemical aggregating tanks which are rapidly stirred by adding a chemical flocculant to the denitrified water in the denitrification tanks, and mixed water of the treated water and the chemical coagulant rapidly stirred in the chemical injection tanks. And the effluent discharged from the chemical agglomeration tank to stabilize the agglomeration floc by slow stirring The poison is provided with an advanced treatment system for sewage, including a disinfection tank.
