摘要
Abstract
Based on the refinery wastewater quality and the existing equipments, the treatment process was improved with focus on the control of bio-nitration conditions. The ammonia nitrogen mass concentration of the effluent is decreased and the effluent quality can meet the discharge standards. The Iiomogenizer is used as pretreatment equipment before the aeration basin, the influent COD of the aeration basin can be decreased from 420 mg/L to 322 mg/L with 23. 3% of average COD removal rate. Adding NaOH solution into the influents of the Iiomogenizer and the contact oxidation pond can keep the system pH alkalescent, the ammonia nitrogen mass concentration of the effluent can be kept below 5.0 mg/L and the average ammonia nitrogen removal rate can be increased from 23.5% to 87.5%.关键词
