The invention discloses a fur
processing wastewater treatment device, which comprises a grid well, a
dyeing water collection well, a
dyeing reaction tank, a primary
sedimentation tank, a
hydrolysis tank, an oxidation tank, a secondary
sedimentation tank, a secondary reaction tank, a final
sedimentation tank, and a
discharge well , a
sludge thickening tank, a chrome liquid collection well, a chrome liquid reaction tank and a chrome mud concentration tank, the
dyeing water collection well is connected to the
dyeing wastewater output end, the
chromium liquid water collection well is connected to the
chromium-containing
wastewater output end, and at the
dyeing wastewater output end Grille wells are arranged between the dyeing
water collection well, between the
chromium waste water output end and the chromium
liquid water collection well, the output end of the dyeing water collection well is connected to the input end of the dyeing reaction
pool, and the output end of the dyeing reaction
pool is connected to The input end of the primary sedimentation tank and the output end of the chromium liquid collection well are connected with the input end of the chromium liquid reaction tank. Through the combination of various treatment processes, the present invention can ensure that the
effluent is discharged up to the standard, and the present invention has simple process, convenient operation, thorough treatment, energy saving and low cost.
