摘要
Abstract
Aiming at the treatment of petrochemical RO concentrated water,the technique of O3-photodegradation-carbon fiber was used to treat the wastewater from a petrochemical corporation in Tianjin and a pilot-scale experiment was carried out.The results show that the optimum pH value is 8 ～9 and the optimum concentration of O3 is 10.0 ～ 13.3 mg/L.COD concentration of the final effluent is less than 40 mg/L,the maximum NH3-N removal rate is 44.6％,and the SS reaches the first grade discharge standard.The operating cost of RO concentrated water is 2.1 CNY per ton.The removal rate of NH3-N can be increased by increasing the internal reflux ratio.When the pH value of the intake water of the carbon fiber device is 8,the adsorption efficiency is the highest.关键词
