| 摘 要： | 以14d作为目标驯化时间,采用SBR反应器比较了厌氧-缺氧(亚硝酸盐一次投加)、厌氧-缺氧-好氧(亚硝酸盐一次投加)、厌氧-好氧+厌氧-缺氧-好氧(亚硝酸盐一次投加)、厌氧-好氧+厌氧-缺氧-好氧(亚硝酸盐连续投加)4种亚硝酸型反硝化除磷污泥驯化方式的优劣.结果表明,经厌氧-好氧+厌氧-缺氧-好氧(亚硝酸盐连续投加)方法驯化后的污泥,能承受的亚硝酸盐初始浓度最高为80mg/L,吸磷速率最高为14mgP/(gVSS·h),所需要的亚硝酸盐投加量较少,是一种较好的亚硝酸型反硝化除磷污泥快速驯化方法.

| Abstract: | The effects of sludge cultivation were investigated under the conditions of anaerobic-anoxic (instantaneous nitrite dosing), anaerobic-anoxic-aerobic (instantaneous nitrite dosing), anaerobic-aerobic + anaerobic-anoxic-aerobic (instantaneous nitrite dosing), and anaerobic-aerobic + anaerobic-anoxic-aerobic (continuous nitrite dosing) using nitrite as electron acceptor applied a sequencing batch reactor (SBR) for 14 days. Sludge cultivated by the method of anaerobic-aerobic + anaerobic-anoxic-aerobic (continuous nitrite dosing) could tolerate the maximum initial nitrite concentration 80 mg/L and the highest phosphate uptake rate 14 mgP/(gVSS·h). The nitrite dosage under this condition was also needed less than others. Therefore this could be a proper way for fast cultivation of denitrifying phosphorus removal sludge using nitrite as electron acceptor. |
