High concentration sugar wastewater treatment device and wastewater treatment method using the same

摘要

The present invention separates the high concentration of sugar wastewater from the general wastewater and treats it separately, and then treats the high concentration of the sugar wastewater using the aerobic biological treatment process of two stages, which is mixed with the general wastewater for subsequent treatment, and the wastewater treatment using the same. It is about a method. Wastewater treatment apparatus of the present invention comprises: (i) a batch high-speed aeration tank (2) for biologically primary treatment of sugar wastewater using aerobic microorganisms; (Ii) a sump (5) for gathering together the supernatant and general wastewater not precipitated in the electric batch aeration tank (2); (Iii) a chemical treatment tank 7 for chemically treating the wastewater collected in the electric collection tank 5; (Iii) a secondary biological aeration tank (9) connected to an agglomeration sedimentation tank (8) for agglomeration of sludge produced in the electrochemical treatment tank (7) and for biologically secondary treatment of the agglomerated supernatant with an aerobic microorganism (9). ); (v) discharge tanks (12) for the discharge of unprecipitated supernatant water during the secondary biological treatment, (i) recycling the precipitated activated sludge into a batch rapid aeration tank (2) or return to a secondary biological aeration tank (9). Recirculation lines 13, 13 'for recharging; And (iii) a sludge dehydrator 14 for removing and solidifying water from the sludge formed in the electricity. By treating the high concentration of sugar wastewater using the wastewater treatment apparatus of the present invention, it is possible to effectively remove the organic matter contained in the sugar wastewater.
