The invention relates to a fur production wastewater treatment device which comprises a regulating tank, an air floatation oxidation tank, a multi-point influent multi-stage biochemical tank and a sand filter, wherein the air floatation oxidation tank comprises an air floatation area, a stirring area and a settling area, an air floatation oxidation tank water inlet pipe is arranged in the middle of the air floatation area, and an air floatation system is arranged at the bottom of the air floatation area; the multi-point influent multistage biochemical tank comprises a multi-point influent multistage biochemical tank water inlet manifold, a primary reaction area, a secondary reaction area and a tertiary reaction area. The primary reaction area comprises a primary facultative aerobic chamber, a primary anoxic chamber, a primary aerobic chamber and a primary settling chamber. A primary reaction area water inlet pipe used for supplying wastewater is arranged at the head end of the primaryfacultative aerobic chamber and is communicated with the multi-point influent multistage biochemical tank water inlet manifold. The tail end of the primary facultative aerobic chamber is communicatedwith the head end of the primary anoxic chamber, and the primary anoxic chamber is provided with a primary anoxic chamber three-phase separator and a primary anoxic chamber sludge discharge valve; both the primary facultative aerobic chamber and the primary anoxic chamber are respectively provided with a primary reaction area air collecting pipe.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a fur production wastewater treatment device. Background technique [0002] With the emergence of fur processing industrial parks and the rapid development of technology, the wastewater produced by the fur processing industry accounts for an increasing proportion of my country's industrial wastewater pollution sources. The fur production wastewater contains many types of pollutants, including the production process A large amount of residual industrial salt, soda ash, sulfuric acid and other chemical dyes, as well as protein and soluble oil used in the processing process, in addition, a large amount of hexavalent chromium is produced in the chrome tanning process, which is highly toxic. If it is discharged directly without treatment, it will seriously pollute the water body , while affecting human health. [0003] At present, fur production wastewater is usually treat...
