Industrial wastewater discharge - refers to the volume of industrial wastewater discharged to the outside of the enterprise from all outlets in the industrial enterprise's plant. It includes production wastewater, direct cooling water discharged to the outside and indirect cooling water with no diversion of clean water and sewage, mine groundwater discharged in excess of the standard and plant domestic sewage mixed with industrial wastewater, excluding plant domestic sewage discharged independently to the outside and indirect cooling water and rainwater with diversion of clean water and sewage.
Industrial wastewater treatment volume - refers to the amount of industrial wastewater actually treated by various water treatment facilities, including the amount of industrial wastewater discharged and reused after treatment.
Industrial wastewater pollutant emissions - refers to the discharge of industrial wastewater contained in chemical oxygen demand, ammonia and nitrogen, volatile phenols, petroleum and other substances.
Centralized Wastewater Treatment Plant Reduction - refers to the amount of pollutants in wastewater reduced by urban wastewater treatment plants, centralized industrial wastewater treatment facilities and other wastewater treatment facilities, excluding the amount of pollutants reduced by in-house wastewater treatment facilities.
The number of wastewater treatment facilities - refers to the actual facilities (including structures) used for the prevention of water pollution and the comprehensive utilization of water resources after treatment, a wastewater treatment system as a unit of statistics, attached to the facilities of water treatment equipment and supporting equipment are not calculated separately.
Industrial exhaust emissions - refers to the total amount of various gases containing pollutants emitted into the air generated during the combustion of fuels and production processes in the enterprise, measured in the standard state (273K, 101325 Pa).
Industrial sulfur dioxide emissions - refers to the amount of sulfur dioxide emitted into the air from various emissions generated during the combustion of fuels and production processes in an enterprise.
Industrial Soot Emissions - The amount of particulate matter entrained in the flue gases produced by fuel combustion in an enterprise's plant.
Industrial dust emissions - refers to the weight of particulate matter emitted by the enterprise during the production process. Excludes soot from combustion processes.
Number of waste gas treatment facilities - refers to the enterprise to reduce the combustion of fuels and production processes in the emission of pollutants into the atmosphere or recycling of pollutants in the physical facilities (including structures). Attached to the facilities within the water treatment equipment and ancillary equipment are not counted separately.
Industrial solid waste generation - refers to the enterprise in the production process of solid, semi-solid and high-concentration liquid waste in general, including hazardous waste, smelting slag, fly ash, slag, gangue, tailings, radioactive waste and other wastes, excluding the stripping of mining waste rock and excavation waste rock (except acidic or alkaline waste rock). ). Acidic or alkaline waste rock refers to the extracted waste rock runoff water, rainwater pH value of less than 4 or greater than 10.5.
Hazardous waste - means waste that is listed on the national hazardous waste list or recognized according to the national criteria and methods for identifying hazardous waste, and that has one of the hazardous characteristics of explosiveness, flammability, oxidizability, toxicity, corrosiveness, and susceptibility to infectious diseases.
Comprehensive utilization of industrial solid waste - refers to the amount of solid waste extracted from solid waste through recovery, processing, recycling, exchange, etc., or make it into resources, energy and other raw materials that can be used.
Industrial solid waste storage - refers to the comprehensive utilization or disposal for the purpose of temporary storage or storage of solid waste in dedicated storage facilities and dedicated centralized storage places. Dedicated solid waste storage sites and storage facilities must have anti-proliferation, anti-loss, anti-leakage, to prevent pollution of the atmosphere, to prevent the pollution of water measures.
Industrial solid waste disposal - refers to the amount of solid waste incineration or finally placed in compliance with environmental protection regulations and no longer take back the amount of industrial solid waste.
Industrial Solid Waste Dumping Disposal - refers to the amount of industrial solid waste discharged outside of solid waste control facilities and sites. Excludes mine stripping waste rock and excavation waste rock (except gangue, acidic or alkaline waste rock).
Electromagnetic radiation equipment - refers to equipment that generates electromagnetic radiation for medical and scientific research.
Radiation source-means a radioactive material, other than material in the nuclear fuel cycle category of research and power reactors, that is permanently sealed in a container or tightly encapsulated and in a solid state.
Radiographic device-means an X-ray machine, gas pedal, neutron generator.
Total Phosphorus and Nitrogen Loss from Cultivation-means the amount of total phosphorus and nitrogen lost through leaching and surface runoff during the cultivation and production of food crops, cash crops and vegetable crops.
Surface runoff and subsurface leaching loss - farmland nitrogen, phosphorus and pesticides are migrated with the loss of water flow, the direction of farmland water flow can be divided into horizontal flow along the surface and underground vertical flow of two cases. In this census, the amount of nitrogen, phosphorus and pesticides lost along the horizontal water flow pathway on the surface is defined as the surface runoff loss, and the amount of nitrogen, phosphorus and pesticides lost along the underground longitudinal water flow pathway is defined as the subsurface leaching loss.
Basic loss-i.e., the amount of nitrogen, phosphorus and pesticides lost from the background of farmland soil-is relative to the loss of the current year's applied amount. In this census, the loss of nitrogen, phosphorus and pesticides accumulated in farmland soil in previous years (not the current year's application) is uniformly defined as the base loss.
Land film residue-refers to the amount of land film that remains in the soil or on the surface of the land that is not recovered or cannot be recovered after the use of land film in the production process of planting.
Pollutant Emissions from Aquaculture - refers to the amount of pollutants discharged into water bodies outside the aquaculture area during aquaculture production.
Urban Residential Source Units - refers to districts, county towns (county-level cities), and formed towns (excluding farms and market towns) in cities with districts.
Medical Waste Generation - refers to the total amount of directly or indirectly infectious, toxic, and other hazardous wastes generated in the course of engaging in medical treatment, prevention, health care, medical teaching and research, and other related activities. Including infectious, pathological, injurious, pharmaceutical, chemical and other hazardous wastes.
Innocuous disposal of medical waste - refers to the use of medical waste in accordance with environmental protection and medical waste management regulations, such as incineration, high-temperature steaming, microwave disinfection and chemical disinfection of medical waste and ultimately to achieve the disfigurement of medical waste, reduce the volume and eliminate the hazardous nature of medical waste, as well as the residue of its disposal process for safe landfill.
