Abstract

The invention discloses a tanning wastewater diversion device, which comprises a liquid collection device arranged below a tanning drum. The liquid collection device comprises a shell and a liquid collection tank, wherein the liquid collection tank is arranged in the shell and is used for collecting wastewater. A liquid drain pipe I and a liquid drain pipe II are arranged on the shell. The liquid inlet of the liquid drain pipe I and the liquid inlet of the liquid drain pipe II are respectively communicated with the liquid collection tank. A diversion ditch I and a diversion ditch II are correspondingly arranged below the liquid outlet of the liquid drain pipe I and the liquid outlet of the liquid drain pipe II. A valve for controlling the make-and-break of the pipe is respectively arranged in the body of the liquid drain pipe I and the body of the liquid drain pipe II. Since chrome tanning wastewater is separated from other tanning wastewater during processing, the invention has the advantages that the treatment of the chrome tanning wastewater is facilitated and the treatment difficulty is reduced.

Description

technical field [0001] The invention relates to a sewage diversion device, in particular to a diversion device for separately separating chromium-containing waste water produced during leather tanning and retanning. Background technique [0002] Tanning is an important process in leather processing. Among the many tanning methods at present, chrome tanning has the best tanning performance. After the raw leather is chrome tanned, the leather body is soft and plump, the inside is fine and elastic, so it is widely used in the industry. recognized. Drums are used in leather tanning, retanning, dyeing, softening and other processes. Since the absorption rate of leather to chrome tanning agent in the chrome tanning process is only about 70%, the remaining chrome tanning agent is discharged with the processing wastewater and mixed with other The mixed sewage produced in the tanning process, chromium-containing wastewater will cause serious pollution to the environment, and must be...
