Industrial wastewater, including production wastewater and polluted industrial wastewater, refers to wastewater and waste liquid generated in the process of industrial production, including materials for industrial production, intermediate products, by-products and pollutants generated in the production process that are all lost with water.

Standard Ecological Environment takes "pollutant source control, internal source treatment and ecological restoration" as the technical route. Mainly using the micro-ecosystem restoration technology, aquatic flora and fauna (ecological floating island of receiving pollution, submerged vegetation, constructed wetland, etc.) aeration and oxygenation technology and other comprehensive treatment to reduce the water pollution load, restore the health of the water ecosystem and water self-purification ability. After the establishment of a complete water ecosystem, it will be operated and maintained in the later period to achieve long-term governance and clear water quality.

Vegetation restoration technology can effectively governance the mine, stabilize the geological environment of the mine and restore the ecological environment.

China adheres to the strictest cultivated land protection system, strengthens the protection of the quantity and quality of cultivated land, strictly abides by the standard 1.8-billion-mu of a minimum arable land area, curbs the "non-agricultural" of cultivated land, prevents the "non-grain production", regulates the balance between the occupation and compensation of cultivated land, strictly prohibits the occupation of superior land to compensate inferior land, and the occupation of paddy land to compensate dry land. Focusing on grain production functional areas and important agricultural product production protection areas, China will build a national food security industrial zone, and implement high standard farmland construction projects to build 1.075 billion mu of concentrated high standard farmland.

In order to effectively prevent the occurrence of environmental risk accidents, quickly and effectively handle possible sudden environmental risk accidents, comprehensively control and eliminate pollution, and ensure environmental safety.
