GB/T 27857-2011 Chemicals—Anaerobic biodegradability of organic compounds in digested sludge—By measurement of gas production
Abstract
This standard specifies the test item information, method overview, test preparation, test procedure, data processing, quality assurance and quality control, and test report for the determination of the anaerobic biodegradability of organic chemicals in digested sludge.
This standard is applicable to known water-soluble chemical substances. When using the standard provided in ISO 10634 [13] for precise dosage preparation, it is also applicable to poorly water-soluble and non-water-soluble chemical substances. When using this standard for volatile substances, specific operational steps need to be taken to verify them step by step, such as determining the airtightness of the test system during the test process.
