A study on the treatment of antifouling paint waste from shipyards, including sandblast waste and ship hull washing wastewater, was performed. The sandblast waste could be effectively detoxified by heat treatment, and the efficiency was affected by the temperature of the heating vessel and treatment time. The removal efficiency of total organotin compounds from the sandblast waste was over 99% at 1000 degrees C and treatment for 1 h. For the treatment of ship hull washing wastewater by the solvent extraction, ship diesel was a good solvent for the tributyltin (TBT) extraction, and the proper amount of solvent was about 10 mL for TBT extraction from 1L of wastewater. The extraction efficiency of TBT was significantly affected by the agitation intensity. The TBT in the wash wastewater was rapidly extracted within 1 h. The level of the TBT residual in the wastewater extracted for 1h was 2.8 microg L(-1), and this was further decreased to 0.8 after 5 h extraction.
开展了一项关于造船厂防污漆废料处理的研究，其中包括喷砂废料和船体清洗废水。喷砂废料可通过热处理有效解毒，其效率受加热容器温度和处理时间的影响。在1000摄氏度下处理1小时，喷砂废料中总有机锡化合物的去除效率超过99%。对于用溶剂萃取法处理船体清洗废水，船用柴油是萃取三丁基锡（TBT）的良好溶剂，从1升废水中萃取TBT的合适溶剂量约为10毫升。TBT的萃取效率受搅拌强度的显著影响。洗涤废水中的TBT在1小时内迅速被萃取。萃取1小时后废水中TBT的残留水平为2.8微克/升，萃取5小时后进一步降至0.8微克/升。
