Abstract:

The main indexes, methods and concerned international standards of organic compound biodegradability evaluation are introduced and the differences are analyzed and compared. The biodegradability of polyaspartic acid(PASP), polyepoxysuccinic acid(PESA)and polyacrylic acid(PAA)are evaluated according to OECD 301B (ISO 9439).The results show that using PCD as the determination method of water treatment chemicals biodegradability is feasible and credible.

Key words: biodegradability, evaluation, water treatment chemicals

摘要:

介绍了有机物生物降解性能评价的主要指标、方法和国际标准, 分析比较了不同的评价方法和国际标准, 并采用OECD 301B(ISO 9439)标准评价了聚天冬氨酸、聚环氧琥珀酸、聚丙烯酸钠的生物降解性能, 指出利用二氧化碳生成量(PCD)法测定水处理剂的生物降解性是可行和可靠的。
