The "GB 25461-2010 Starch Industry Water Pollutant Discharge Standard" stipulates the emission limits, monitoring and monitoring requirements of water pollutants in starch industrial enterprises, and is applicable to the management of water pollutant discharge in existing and new starch enterprises. The pollutant discharge concentration in the standard is mass concentration, covering environmental impact assessment, design of environmental protection facilities, environmental protection acceptance after completion and discharge management after commissioning. Since the date of implementation, it has replaced the relevant provisions of the starch industry in the "Comprehensive Sewage Discharge Standard" (GB 8978-1996), which plays an important role in controlling the discharge of water pollutants in starch production and protecting the water environment.
