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 "," State Council on Strengthening Key Environmental Protection Tasks "and other laws and regulations," State Homes for the preparation of the national main functional area planning advice "to protect the environment, prevent pollution and promote hemp production processes and pollution Treatment advances in technology, the development of this standard. This standard specifies the industrial hemp production process water pollutant discharge limits, and monitoring requirements. To promote the region Domain economic and environmental development, promoting the adjustment and economic growth mode transformation of economic structure, industrial production workers guide linen Development Direction and pollution control technologies, this standard specifies the particular water pollutant discharge limits. The standard emission concentrations of pollutants are mass concentration. Hemp National Pollutant emissions of industrial enterprises air pollutants (including odor pollutants), apply appropriate environmental noise emissions Standard, solid waste to produce identification, treatment and disposal of solid waste pollution control applicable national standards. This standard is the first release. Since the implementation of this standard, linen industrial enterprises degumming water pollutant emission control implementation of the provisions of this standard, no longer The implementation of "Integrated Wastewater Discharge Standard" (GB 8978-1996), linen dyeing wastewater of industrial enterprises to perform "textile industrial water Pollutant emission standards "(GB 4287-92). Local people's governments at the provincial level are not specified in this standard pollutants may establish their local emission standards; for This standard has been provided for projects of contaminants, may establish more stringent standards in this local emission standards. This standard is developed by the Ministry of Environmental Protection Science, Technology organization. This standard drafting units. China Light Industry Cleaner Production Center, Ministry of Environmental Protection Standards Institute, Hunan Ma Yuanjiang City Star Co., Ltd. This standard MEP September 11, 2012 for approval. This standard since January 1, 2013 implementation. The standard explanation by the Ministry of Environmental Protection. GB 28937-2012 Hemp industrial water pollutant discharge standards

1 Scope
