ABR工艺ANAMMOX耦合短程硝化协同脱氮处理城市污水
|
摘要
厌氧氨氧化技术如能替代市政污水厂的主流工艺,将大幅降低市政污水处理能耗.故采用ABR反应器,构建除碳系统、短程硝化系统和厌氧氨氧化系统,将三者耦合成一体化短程硝化-厌氧氨氧化反应器进行城市污水脱氮.结果表明,ABR除碳系统的HRT为4.5 h时,其出水COD平均浓度为80 mg·L~(-1),不会对后续短程硝化系统产生不利影响,出水TN平均浓度为10mg·L~(-1),厌氧氨氧化系统TN容积负荷为0.36 kg·(m~3·d)~(-1).当控制DO为1~2 mg·L~(-1)时,亚硝化率能长时间维持在90%左右,有利于保证后续厌氧氨氧化系统的稳定运行.当控制温度为30℃左右,好氧区DO为1~2 mg·L~(-1)良时,短程硝化-ANAMMOX一体化ABR工艺可以对城市污水稳定高效地脱氮.
If the technology of anaerobic ammonium oxidation( ANAMMOX) can substitute the mainstream technology of municipal wastewater treatment plant,the energy of municipal wastewater treatment will be decreased significantly. Thus,anaerobic baffled reactor( ABR) was used to build carbon system,shortcut nitrification system and anaerobic ammonia oxidation system. And the three systems were coupled to shortcut nitrification-anaerobic ammonia oxidation reactor to treat municipal wastewater. The results showed that the average effluent COD concentration of carbon removal system was 80 mg·L~(-1) when the hydraulic retention time of carbon removal system was 4. 5 h. And the subsequent shortcut nitrification system would not be adversely affected by the effluent COD.Finally,the average effluent total nitrogen concentration was 10 mg·L~(-1),with total nitrogen volume load of ANAMMOX system of 0. 36kg·( m~3·d)~(-1). When the dissolved oxygen was controlled between 1 to 2 mg·L~(-1),the nitrite accumulation rate could be maintained around 90%,ensuring the stable operation of the subsequent anaerobic ammonia oxidation system. The nitrogen of municipal wastewater could be stable and efficiently removed by the shortcut nitrification-ANAMMOX integration ABR with temperature of 30℃and dissolved oxygen of 1-2 mg·L~(-1).
