摘要

裂化催化剂生产过程中产生的高盐度、高浊度、高氨氮、低C/N比废水难以处理。构建了电絮凝-半短程硝化-厌氧氨氧化组合工艺

考察了该组合工艺对实际裂化催化剂废水的处理效果以及处理稳定性。结果表明组合工艺处理裂化催化剂废水具有较好的稳定性

出水水质稳定在以下水平:浊度< 30 NTU

NH4+-N< 10 mg·L-1

NO2--N< 3 mg·L-1

NO3-< 40 mg·L-1

COD< 100 mg·L-1;通过进水氨氮浓度确定曝气时间的方式可以保证长期稳定的半短程硝化过程

出水NO2-/NH4+-N比值维持在0.9～1.4之间

满足厌氧氨氧化反应器的进水要求;同时在裂化催化剂废水的高盐度胁迫下厌氧氨氧化工艺能够表现出显著的厌氧氨氧化效果。

Abstract

Wastewater from cracking catalyst production line of petroleum refining industry is difficult to be treated with high density of salinity

high concentration of SS and ammonia

and low C/N. The research focused on the construction of electrocoagulation-partial nitritatiom-Anammox process

the performance and stability of the process towards cracking catalyst wastewater. The results showed that the system got strong stability to treat cracking catalyst wastewater. The effluent quality remained: turbidity< 30 NTU

NH4+-N< 10 mg·L-1

NO2--N< 3 mg·L-1

NO3-< 40 mg·L-1 and COD< 100 mg·L-1. By the control of aeration time according to the concentration of ammonium nitrogen

the partial nitritation can be achieved stably and theNO2-/NH4+-Nof effluent kept in 0.9 to 1.4 which can satisfied the need of the Anammox. The Anammox process can still show the Anammox effect markedly in the cracking catalyst wastewater with high salinity.
