Abstract

Abstract:

Using low substrate simulated wastewater(NH₄⁺-N and NO₂^--N are(25±0.4)mg/L and(33±0.6)mg/L respectively),at temperature(23±0.5)℃,the rapid start-up of anaerobic ammonium oxidation(Anammox) process anaerobic sequencing batch reactor(ASBR) has been studied. In Stage Ⅰ,HRT is 24 h and pH uncontrolled,in thalli autolysis phase effluent NH₄⁺-N is 69 mg/L,in activity stagnate phase the effluent and influent NH₄⁺-N are almost the same. In Stage Ⅱ-Ⅲ,the thalli is in up-going period,their HRT are 12 h and 8 h,respectively,and pH is controlled at 8.0-8.2,the effluent NH₄⁺-N decreases to 1.6 mg/L,while NO₂^--N increases first,then decreases. In StageⅣ,HRT is 4 h,and pH controlled at 8.0-8.2,the effluent NH₄⁺-N and NO₂^--N both are lower than 1 mg/L, and the TN removing load is 352.3 mg/(L·d),△m(NH₄⁺-N):△m(NO₂^--N):△m(NO₃^--N)=1:(1.33 ± 0.02):(0.26±0.02),indicating that the Anammox ASBR reactor is successfully started up.

Key words: low substrate, Anammox, anaerobic sequencing batch reactor(ASBR), quick start-up

摘要：

采用低基质模拟废水[NH₄⁺-N、NO₂^--N分别为（25±0.4）、（33±0.6）mg/L]，在温度为（23±0.5）℃的条件下，研究了厌氧氨氧化ASBR反应器的快速启动。第Ⅰ阶段HRT为24 h，pH不控制，菌体自溶期出水NH₄⁺-N为69 mg/L，活性停滞期出水NH₄⁺-N与进水几乎相等；第Ⅱ~Ⅲ阶段，菌体处于活性提高期，HRT分别为12、8 h，pH控制为8.0~8.2，出水NH₄⁺-N降低到1.6 mg/L，NO₂^--N均先升高后降低；第Ⅳ阶段HRT为4 h，pH控制为8.0~8.2，出水NH₄⁺-N和NO₂^--N均低于1 mg/L，TN去除负荷为352.3 mg/（L·d），△m（NH₄⁺-N）：△m（NO₂^--N）：△m（NO₃^--N）=1：（1.33±0.02）：（0.26±0.02），反应器启动成功。
