Description
Technical field
The utility model is related to wastewater treatment manufacture field, more particularly to a kind of pickling waste waters processing equipment.
Background technology
Stainless cast steel part surface during production can all be stained with the materials such as oxide skin, crator, slag point, molding sand,
Generally the method for pickling is all taken to be removed.And some products are high for surface smoothness, before warehouse entry generally
The mode of passivation is taken to improve the surface quality of casting.
Above-mentioned pickling, passivating process can use substantial amounts of inorganic acid (hydrochloric acid, nitric acid, hydrofluoric acid, sulfuric acid etc.) and few
These spent acid for steeping product are generally directly discharged into sewer or river by the organic acid (oxalic acid etc.) of amount, some individual workships
In, the environment of severe contamination.And some small enterprises are generally also simply diluted with water or add alkali to neutralize, but to the mud of generation
Any processing is not done, due to containing substantial amounts of iron, chromium and nickel in stainless steel, so containing substantial amounts of Cr6 in acid solution and mud
+, Ni2+ and Fe3+, especially Cr6+ are very big to human injury, due to easily being accumulated in human body, once it is mixed into underground water, well
