This standard was formulated by the Department of Soil Ecology and Environment and the Department of Regulations and Standards of the Ministry of Ecology and Environment. The main drafting organizations of this standard. Chinese Academy of Environmental Sciences, Nanjing Institute of Environmental Sciences, Ministry of Ecology and Environment, Soil and Agricultural and Rural Ecological Environment Supervision Technology Center, Environmental Protection Research and Monitoring Institute of Ministry of Agriculture and Rural Affairs. This standard was approved by the Ministry of Ecology and Environment on January 9, 2021. This standard shall be implemented from July 1, 2021. This standard is interpreted by the Ministry of Ecology and Environment. Irrigation water quality standards for farmland1 Scope of applicationThis standard specifies requirements for irrigation water quality, monitoring and analysis methods, and supervision and management requirements for farmland irrigation. This standard applies to water quality supervision and management that uses surface water and groundwater as irrigation water sources for farmland. Urban sewage (industrial wastewater and medical sewage (Except water) and unutilized livestock and poultry breeding wastewater, agricultural product processing wastewater and rural domestic sewage enter the farmland irrigation channel, and its downstream The water quality of the nearest irrigation point shall be supervised and managed in accordance with this standard.2 Normative referencesThis standard quotes the following documents or their clauses. For dated reference documents, only the dated version applies to this standard. For undated references, the latest version (including all amendments) applies to this standard.
