DB51/ 3204-2024 Standard for Emission Control of Water Pollutants from Non-ferrous Metals Smelting and Silicon Crystal Industry in Sichuan Province

Scope

This document stipulates the control requirements for water pollutant emissions, monitoring requirements, and supervision and management requirements for industrial wastewater discharge units in the non-ferrous metals smelting (aluminum, zinc, copper, nickel, titanium, rare earth) and crystalline silicon industries within the jurisdiction of Sichuan Province. This document applies to the management of water pollutant emissions for existing non-ferrous metals smelting (aluminum, zinc, copper, nickel, titanium, rare earth) and crystalline silicon industrial wastewater discharge units in Sichuan Province, as well as to the environmental impact assessments, environmental protection facility design, acceptance of completed environmental protection facilities, issuance of discharge permits, and post-operation management of water pollutant emissions for new, modified, and expanded non-ferrous metals smelting (aluminum, zinc, copper, nickel, titanium, rare earth) and crystalline silicon industrial wastewater discharge projects. This document does not apply to industries such as non-ferrous metal mining (aluminum, zinc, copper, nickel, titanium, rare earth), non-ferrous metal (aluminum, zinc, copper, nickel, titanium, rare earth) recycling, and rolling processing. For other non-ferrous metals smelting industries and other water pollutants not specified in this document, the provisions of relevant national or Sichuan provincial water pollutant emission standards shall apply.
