GB/T 21795-2008 Chemicals—Simulation test—Aerobic sewage treatment—Biofilms
Abstract
This standard specifies the method overview, test preparation, test procedures, quality assurance and quality control, data and reporting for the aerobic treatment of wastewater by biofilm method using chemical simulation tests. This standard applies to chemicals that are inherently biodegradable but not rapidly biodegradable, and also to substances requiring more information, especially high-registration-tonnage chemicals. Substances that are poorly soluble in water and volatile substances need to undergo special pretreatment before testing.
