Abstract

The invention relates to a pollution control structure of a tanning water yard and a pollution control method for the tanning water yard. According to the pollution control structure, a preparation stage and a tanning stage are respectively both provided with four washing liquor pools; a washing liquor is divided into eight parts and respectively stored, a primary washing liquor, a secondary washing liquor, a tertiary washing liquor and a quaternary washing liquor are sequentially used for washing in the preparation stage according to the sequence of dirty water first and then purified water; and in the tanning stage, a primary tanning washing liquor, a secondary tanning washing liquor, a tertiary tanning washing liquor and a quaternary tanning washing liquor are sequentially used for washing, and a vulcanization alkali liquor pool of the preparation stage, a saline water pool, an acid water pool, a chromium liquor pool, a heating liquor pool, an alkali extraction liquor pool and a concentrated ammonia liquor pool of the tanning stage as well as a water washing pool, a retanning liquor pool, a color liquor pool and a color oil liquor pool of a dying stage are utilized; and the liquors generated in various working procedures are classified and orderly stored. Due to the adoption of the pollution control structure of the tanning water yard, the purposes of recycling the washing liquors and singly and purposefully purifying sewage can be better achieved so as to improve the water saving effect and relieve the sewage treatment stress.

Description

technical field [0001] The invention relates to the technical field of pollution control in a tannery water field, in particular to a pollution control structure and a pollution control method for a tannery water field. Background technique [0002] In the tanning process, a large amount of water resources are needed for cleaning, resulting in waste of water resources and wastewater pollution, making the tanning industry a high water consumption and heavy pollution industry second only to the paper industry in light industry. At present, the treatment of tannery sewage is mainly pure treatment, rather than recycling water and recovering useful substances. [0003] The invention patent with the application number 200720110004.0 discloses a tannery sewage diversion conduit, which is divided into three types: the degreasing mixture diversion conduit, the cleaning water diversion conduit and the chemical pollutant diversion conduit. Several shunt gates are installed and are fre...
