Guidelines for Best Available Techniques for Electroplating Pollution Prevention and Control Released

The Ministry of Environmental Protection recently issued the “Guidelines for the Best Available Techniques for Electroplating Pollution Prevention and Control (Trial)”, which provides technical basis and guidance for the industry to improve its technological level, carry out pollution control and related environmental supervision.

The technical guide first analyzes the treatment technology of process pollution prevention, wastewater treatment, spray tower electroplating waste gas, dust removal, wastewater sludge treatment and disposal, and points out the advantages and disadvantages of various main treatment technologies and their scope of application. On this basis, various best available technology combinations were put forward, and its process parameters, pollutant reduction and emission, economic applicability, etc. were clarified around the technology, and as many as 44 technical application considerations were also proposed, which has strong Guidance.

The pollution produced by the electroplating process includes water pollution, air pollution, solid waste pollution and noise pollution, including water pollution (mainly containing heavy metal ions, cyanide, acid and alkali and organic pollutants), air pollution (mainly containing various acid mist and dust ) And electroplating wastewater treatment sludge pollution (mainly containing heavy metals and cyanide) are the main environmental problems.
