Abstract: A great deal of sludge and spent activated carbon from the petrochemical wastewater which was treated by the PACT(powdered activated carbon biochemical treatment) process has been regenerated by the WAR(wet air regeneration) unit built by the wastewater treatment plant of Anqing Petrochemical Branch Co., SINOPEC. The results show that the adsorption capacity of activated carbon regenerated by WAR unit can meet the requirements of wastewater biochemical treatment. The oxidation waste gas from WAR unit and the regenerated activated carbon can be back to PACT system and used, so as to reduce the discharge of oxidation waste gas and the consumption of fresh activated carbon. The regenerated activated carbon amounts to 9010 kg/d, which is 90.5% of the daily amount of powdered activated carbon for biochemical treatment. Since the cost has been reduced, the recycling of wastewater, waste carbon and waste gas are realized and the environment pollution caused by the “three wastes” is avoided.

Key words: spent activated carbon, wet air regeneration, recycling, installation and debugging

摘要： 利用中国石化安庆分公司污水处理场建设的湿式空气再生（WAR）装置，对粉末活性炭生化技术（PACT）处理石化污水产生的大量污泥和废活性炭进行再生。结果表明，经WAR装置再生的活性炭的吸附性能满足污水生化处理要求，再生活性炭和WAR装置产生的氧化废气可重返PACT系统使用，减少了氧化废气外排及新鲜活性炭用量。再生活性炭回用量达9010 kg/d，占生化处理粉末活性炭日用量的90.5%，降低了成本，实现了废水、废炭、废气的回收利用，避免了“三废”排放造成的环境污染。
