Abstract

The invention discloses a purifying agent for leather manufacturing wastewater. The purifying agent is characterized by comprising components in parts by weight as follows: 35-45 parts of modified diatomite, 25-30 parts of sulfuric acid, 20-25 parts of lime powder, 5-15 parts of tannin, 5-15 parts of ferrous sulfate and 10-15 parts of lignin. The treatment agent for the wastewater is prepared according to characteristics of the leather manufacturing wastewater, can effectively decompose harmful substances in the leather manufacturing wastewater, cannot cause secondary pollution and has a good purification effect on the leather manufacturing wastewater, and the water treatment standard is met.

Description

technical field [0001] The invention relates to the field of purifying agents, in particular to a purifying agent for tanning wastewater. Background technique [0002] Wastewater will be produced in the leather manufacturing process, which contains a large amount of heavy metals and toxic organic solvents. If it is not treated in time and discharged randomly, it will cause serious pollution to the soil and groundwater at the discharge site, endangering human health. There is no special purifier for waste water, and the existing purifiers are not very effective in purifying tannery wastewater. [0003] Therefore, prior art also needs further development and improvement. Contents of the invention [0004] The object of the present invention is to provide a purifying agent for tannery wastewater, aiming at solving the problem of unsatisfactory treatment effect of tannery wastewater at present. [0005] Technical scheme of the present invention is as follows: [0006] A pur...
