摘要：采用催化臭氧氧化—生物活性炭吸附组合工艺处理反渗透(RO)浓水,比较了4种催化剂催化臭氧氧化的性能,优化了初始RO浓水pH、臭氧氧化时间、生物活性炭柱空床停留时间(EBRT)等工艺条件。实验结果表明:以WP-01为催化剂催化臭氧氧化RO浓水时无需调节废水pH;臭氧氧化反应5 min时RO浓水的BOD5/COD达0.28,可生化性得到显著改善;WP-01催化剂重复使用30次其催化活性没有明显下降;生物活性炭吸附单元的EBRT控制在30 min左右,可确保出水COD稳定在50 mg/L以下,符合GB 18918—2002《城镇污水处理厂污染物排放标准》的一级A标准;催化臭氧单元处理每吨RO浓水的电费约为1.22元。
The reverse osmosis （RO） concentrated water was treated by the combination process of catalytic ozonation- biological activated carbon （BAC）adsorption. The catalytic capabilities of 4 catalysts on ozonation were compared. The process conditions were optimized. The experimental results showed that： When WP-01was used as catalyst, the wastewater pH needn＇t to adjust; After ozonation for 5 min, the biodegradability of the RO concentrated water was improved significantly with 0.28 of BODs/COD value; The activity of WP-01 catalyst didn＇t obviously decrease after 30 times of reuse; When the empty bed residence time （EBRT）of BAC adsorption unit was controlled at 30 min, the final effluent COD could be stabilized below 50 mg/L, which met the first grade （class A） of national discharge standard GB 18918-2002; The electric charge of the catalytic ozonation unit was about RMB 1.22 yuan per ton.
