Foreword

To implement the "People's Republic of China Environmental Protection Law", "People's Republic of China Water Pollution Prevention Law," "People's Republic of China And the National Marine Environmental Protection Law "and other laws and regulations to protect the environment, prevent pollution and promote the production of leather and fur processing enterprises Process and pollution control technology advances, the development of this standard. This standard specifies the leather and fur processing enterprises water pollutant discharge limits, and monitoring requirements, focusing on regional regulations Especially given the water pollutant discharge limits. Leather and fur processing enterprises discharge of air pollutants (including odor pollutants), environmental Noise of the corresponding national pollutant discharge standards, resulting in the identification of solid waste, treatment and disposal of solid waste applicable national Pollution control standards. This standard is the first release. Leather and fur processing enterprises in new enterprises since March 1, 2014, existing companies since July 1, 2014 onwards, A water pollutant emission control implementation of the provisions of this standard, no longer perform "Integrated Wastewater Discharge Standard" (GB 8978-1996) The relevant regulations. This standard is the basic requirement tanning industrial water pollutant emission control. Local people's governments at the provincial level are not specified in this standard Contaminants may establish their local emission standards; this standard has been provided for projects pollutants may establish Stricter than the present standard of local emission standards. Environmental impact assessment documentation requirements more stringent than this standard or local standards, in accordance with Environmental impact assessment document approved execution. This standard is developed by the Ministry of Environmental Protection Science, Technology organization. This standard drafting units. China Leather Association, China Light Industry Cleaner Production Center, Ministry of Environmental Protection environmental standards graduate School. The Ministry of Environmental Protection Standards December 16, 2013 for approval. This standard since March 1, 2014 implementation. The standard explanation by the Ministry of Environmental Protection. Leather and fur processing industrial water pollutant discharge standards
