摘要
对活性污泥的培养与驯化条件进行了研究。试验表明，采用一次培养法接种，接种量为30％（V）（反应器容积比）的活性污泥和100mL活性炭，将温度控制在37±2℃，进水的pH控制在7．3-8．0，进水流速控制在使活性炭处于流化状态，不需额外添加营养物质，可在25～30天左右成功地完成驯化，在此控制条件下培养出的活性污泥，对废水COD的去除率可达到85％左右．对减轻生物反应器后续处理单元的负荷具有重要意义。
The conditions of culturing and acclimating activated sludge have been researched in this experimentation,it showed that acclimation was finished suecessfully about 25 -30 days in that conditions, throwing the activated sludge （30% cubage of AFB） and 100mL granular activated carbon （GAC） into AFB only one time, culturing and acclimating at 37 ± 2℃, pH7.3- 8.0, the speed of income water just to make GAC fluid, no appeeding nutritive material. After acclimation, the removal efficiency of COD can reach around 85 %. which is great significance to reduce burthen for coming continuous treatment of bio-reactor
