Metal materials and product blanks must be pickled before spraying and rolling. For example, cold-rolled plates, steel pipes, hot-dip galvanizing, steel ropes, copper, aluminum, titanium, stainless steel, etc. Metal pickling waste liquid is divided into two types: waste pickling liquid and acid rinse water. The waste pickling liquid is discharged from dozens to hundreds of cubic meters every day, and the acidic wastewater is usually several times that of the waste acid liquid.
