摘要
根据生物除磷试验和非稳态生物处理工艺研究，提出了厌氧快速吸收污水处理新工艺，并对生活污水处理进行了初步研究。结果表明，在以萄萄糖为主要基质的配制污水试验中，停留时间３０ ～６０ ｍｉｎ，几种不同运行方式ＣＯＤ 去除率均达到８０ ％ 以上，有的甚至达到９０ ％ 以上，短期的实际生活污水试验ＣＯＤ去除率也达６０ ％ 以上；反应器内污泥能在高ＭＬＳＳ 下保持良好沉降性能，已发现有较成熟的颗粒污泥。
A new anaerobic fast absorption wastewater treatment process based on the study of biological phosphorus removal and non -steady state condition is described in this paper and the test on this process used in treating domestic wastewater is presented . The experimental results showed that the COD removal was above 80% even reached 90% at the retention time of 30 ～ 60 min under different running patterns when the influent was artificial wastewater containing glucose as the main organic substrate . In addition, COD removal was above 60% when the influent was raw domestic wastewater. Sludge in the reactor was kept good settlement characteristics in high MLSS and mature gramuar sludge was found . It is clear that the process is efficient and power saving with less excess sludge production.
