以氨氮作为SBR处理对甲苯胺废水的控制参数

Using ammonia nitrogen as control parameter for treatment synthetic p-toluidine wastewater in SBR

采用大孔树脂白球固定化微生物强化SBR处理含对甲苯胺废水，考察了降解过程中对甲苯胺与氨氮浓度变化的相关性．结果表明当反应器中氨氮浓度由上升转为下降的时候，对甲苯胺基本完全降解．在进水中蔗糖浓度为0～500mg／L。曝气量为0．6-1．2L/min，温度为10—25℃的实验条件下。氨氮与对甲苯胺浓度变化表现出良好的相关性．

Adopting macropore resin whole ball immobilized microorganisms enhanced sequencing batch reactor （SBR） for treating p-toluidine wastewater, the relationship between the concentrations of ammonia nitrogen （NH3-N） and p-toluidine in the degradation process of p-toluidine was investigated. When the concentration of NH3-N turned from increase to decrease; the p-toluidine degradation was complete basically. Under testing conditions of the range concentration of sucrose in influent was 0-500mg/L, the range of aerated quantity was 0.6-1.2L/min and the range of temperature was 10-25℃, the relationship between NH3-N and the concentrations ofp-toluidine was good.
