摘　　要：参照OECD301B标准,研究了聚环氧琥珀酸(PESA)及工业上常用的两种反渗透阻垢剂PTP-0100、MDC220的可生物降解性.研究表明,PTP-0100及MDC220均可生物降解,但PESA的可生物降解率达到93.5%,远高于PTP-0100和MDC220,属于易降解的绿色环保型反渗透阻垢剂.According to OECD301B standard, the biodegradability of Polyepoxysuccinic acid （ PESA） and two kind of common RO scale inhibitors in industry PTP-0100 and MDC220 are studied. The result indicated that PTP-0100 and MDC220 are biodegradable and the biodegradation rate of PESA could reach 93.5% which is much higher than PTP-0100 and MDC220. This result proves PESA an easily biodegraded and green environmental RO scale inhibitor;
