In Support of Rio+20 Future We Want
This initiative is in support of paragraph 127 of the Rio+20 outcome document, the Future We Want

Description/achievement of initiative

Until 2015, the following emission reduction objects will be acheived:
Reduce chemical oxygen demand (COD) emission in waste water by 55 tons per year
Reduce paint slag emission by 120 tons per year.
Reduce SO2 and oxynitride emission by 20 tons per year and 30 tons per year respectively.
In electroplating procedure, achieve zero emission of waste water and reduce emission of chromium electroplating sludge by 80%, i.e. 40 tons per year.

Implementation methodologies

Use waste water treatment station to reuse waste water for production and greening.
Apply new coating technology “powder painting”
Remold the established coal-fired boiler and replace coal by sawdust.
Introduce wastewater reclamation technology: collating-ultrafiltration-sterilization three level combination technologies. The waste water is reused to the production process after the treatment.
Introduce new equipment and chromium electroplating wastewater treatment technology: use electrochemical methods-ultrafiltration-reverse osmosis combination technology. The waste water is reuse to the production process without emission.
