Wasted water teatment method at the food waste recycling facilities connected with a communitysewage disposal plant

摘要

Food waste and waste water treatment method (referred to as negative waste water) is linked to the recycling plant and sewage treatment plant of the present invention is a solid-liquid separation treatment process for removing about 45% or more of the solids in the waste water through a solid-liquid separator; Solid-liquid separator washing and salt dilution process to wash the solid-liquid separator after the solid-liquid separation process using distilled water from the sewage treatment plant and to dilute the salts of the wastewater; and adding catalytic oxidation water to the solid-liquid treated water. Primary oxidative decomposition process to break the bound state to facilitate precipitation; The first oxidatively treated water is separated into the upper water through the sedimentation is transferred to the secondary oxidative decomposition reaction tank, the lower sedimentation sludge is sent to the concentration tank Sedimentation separation process; the lower sedimentation sludge transferred to the concentration tank is agglomerated by adding a chemical and then centrifugal Can be dewatered cake is discharged to landfill and dewatering the filtrate is transferred to the secondary oxidative decomposition tank mixing step is mixed with the upper layer can; secondary oxidative decomposition process; Chemical flocculation separation process; And a discharging step.;Ceramic Catalyst, Catalytic Oxidation, Sodium Hypochlorite, Negative Wastewater, Solid-Liquid Separation, Sewage Treatment Plant, Denitrification, Carbon Source, Recycled Water, Effluent, Ocean Emission
