| 摘 要： | 聚羟基烷酸酯(polyhydroxyalkanoate,PHA)是一种生物可降解塑料,利用活性污泥合成PHA具有操作方便的优点.本研究对长期驯化的厌氧-好氧活性污泥工艺在厌氧条件下及好氧活性污泥工艺在好氧条件下利用乙酸合成PHA进行了比较分析,发现好氧活性污泥可以合成较多的PHA.在此基础上,研究了好氧条件下乙酸加入次数、乙酸浓度及硝化抑制剂(丙烯基硫脲,ATU)对PHA合成的影响,结果表明,将乙酸分3次加入到反应器、乙酸浓度为2 925 mg/L及加入6.74 mg/L ATU时,可以使污泥挥发性悬浮固体物中PHA的含量达到56.3%.

| Abstract: | Polyhydroxyalkanoate(PHA) is a type of biodegradable plastics.The synthesis of PHA by activated sludge has the advantage of easy operation.With acetic acid as the carbon source,the anaerobic synthesis of PHA in the anaerobicaerobic activated sludge system was compared with the aerobic one in the aerobic sludge system.It was observed that the aerobic PHA synthesis was greater than the anaerobic one.The influences of acetic acid addition frequency,acetic acid concentration and allyl thiourea(ATU) on aerobic P... |
