    Foreword


    In order to implement the laws and regulations of the Environmental Protection Law of the People's Republic of China, the Law of the People's Republic of China on Water Pollution Control, and the Regulations on the Prevention and Control of Water Pollution in Henan Province, strengthen the supervision and management of water pollutant discharge in the Jialu River Basin and further improve the Jialu River Basin Quality of water environment, formulate Henan Province sewage discharge standards.
    This standard specifies water pollutant discharge limits, monitoring and monitoring requirements in the Jialu River Basin.
    The discharge management of water pollutants from the livestock and poultry breeding industry in the Jialu River Basin implements the regulations of GB18596.
    After the implementation of this standard, water pollutant discharge standards in other river basins in the Jialu River Basin will no longer be implemented.
    This standard was proposed by the Henan Provincial Department of Environmental Protection.
    This standard was drafted: Henan Academy of Environmental Protection Science, Zhengzhou Research Institute of Environmental Protection, Henan Environmental Monitoring Center.
    The main drafters of this standard: Lu Dongxia, Li Jie, Sun Xiangqun, Yu Li, Liu Baotang, Chen Jing, Zhang Xuehua, Shi Lieyan.
    The drafters of this standard: Huang Qun, Ren Yake, Zhou Xiaoli, Li Qiaoxia, Lu Dan, Liu Chi.
    This standard was approved by the People's Government of Henan Province on June 18, 2014.
    This standard is issued for the first time and will be implemented from June 26, 2014.
    This standard is explained by the Henan Province Environmental Protection Department.


    Discharge Standards of Water Pollutants in the Jialu River Basin

    Jialu River pollution control


    1 Scope This standard specifies the water pollutant discharge limits, monitoring and monitoring requirements of the Jialu River Basin, as well as relevant provisions for the implementation and supervision of the standard.
    This standard applies to the discharge management of water pollutants in the Jialu River Basin, as well as the environmental impact assessment of construction projects, the design of environmental protection facilities, the completion acceptance, and the sewage discharge management after its commissioning.
