1 Scope

This standard specifies the terms and definitions special metal phosphate phosphorus in waste water recycling technology to produce metal phosphate wastewater, wastewater metal phosphide Of metal phosphate phosphorus in waste water recycling and safety. This standard applies to chemical treatment - precipitation recycling metal phosphate phosphorus in waste water.

2 Terms and definitions

The following terms and definitions for use in the present document. 2.1 Phosphide phosphorization Phosphate is a process of chemical and electrochemical reaction to form a phosphate chemical conversion coating film. 2.2 Phosphate conversion coating phosphateconversioncoatings Metal (mainly steel) after containing zinc (Zn), manganese (Mn), chromium (Cr), was treated with iron (Fe) and other phosphate in the base metal sheet Surface forming an insoluble phosphate film. 2.3 Phosphating phosphating The metal materials and parts placed in a phosphate solution containing manganese, iron, zinc in chemical treatment of the metal material and workpiece surface Generate a phosphate process protection film is insoluble in water. 2.4 Metal phosphate waste metalphosphidewastewater Metal phosphate waste water is wastewater, wastewater phosphorus metal surface by degreasing, degreasing, surface conditioning, phosphating and other major processes generated.

3 metal phosphide generate wastewater

Metal phosphating process typically includes caustic degreasing, rinsing water, cold water rinsing, pickling rust, and phosphate, and other secondary cold rinse step. in Its process, mainly produce caustic emulsified wastewater, rinsing water, acid phosphate waste and other waste water.

4 metal phosphate wastewater characteristics

Mainly in the form of inorganic salts such as zinc dihydrogen phosphate presence, in addition to acid, alkali substances, oil and suspended solids and other pollutants. due to Different phosphating process may also contain a certain amount of nickel ions (Ni2), copper ion (Cu2) or lead ions (Pb2) and other heavy metal ions and tables Surface active agent.

5 metal phosphate phosphorus in waste water recycling
