摘要:
为使采用臭氧-活性炭深度处理工艺的水厂更好应对2-甲基异莰醇（2-MIB）问题，进行了一系列2-MIB去除规律的生产性试验和探索分析。结果表明，仅有活性炭滤池对2-MIB去除率为50%~70%，主加氯后2-MIB出现明显释放，出厂水2-MIB>10 ng/L。原水2-MIB为10~30 ng/L时，宜采用主臭氧/活性炭滤池工艺组合，对2-MIB去除率为62%~75%，臭氧投加总量为0.7~0.8 mg/L，出厂水2-MIB低于10 ng/L；原水2-MIB为30~100 ng/L时，宜采用预臭氧/主臭氧/活性炭滤池工艺组合，对2-MIB去除率为92%~97%，臭氧投加总量约1.0~1.1 mg/L，出厂水2-MIB低于10 ng/L。活性炭滤池内藻类浓度增加约33.4%，可采取遮光措施予以缓解。臭氧投加总量低于1.4 mg/L时，混凝沉淀池与活性炭滤池对溴酸盐的去除效果优异，臭氧两级投加相对于单级投加，出厂水溴酸盐超标风险更低。
Abstract:
In order to put forward a solution to 2-methylisoborneol (2-MIB) problem in waterworks using ozone-activated carbon filtration process, a series of production tests and exploration of 2-MIB removal rules were carried out. The results showed that the removal rate of 2-MIB in activated carbon filtration was 50%-70%, the 2-MIB was obviously released after the main chlorination, and the effluent 2-MIB was greater than 10 ng/L. When the 2-MIB in raw water was 10-30 ng/L, the combination of post-ozonation/activated carbon filtration should be adopted. The removal rate of 2-MIB was 62%-75%, the total amount of ozone dosage was approximately 0.7-0.8 mg/L, and the effluent 2-MIB was lower than 10 ng/L. When the 2-MIB in raw water was 30-100 ng/L, the combination of pre-ozonation/post-ozonation/activated carbon filtration should be adopted. The removal rate of 2-MIB was 92%-97%, the total amount of ozone dosage was approximately 1.0-1.1 mg/L, and the effluent 2-MIB was less than 10 ng/L. The algae concentration in activated carbon filtration increased by 33.4%, which could be alleviated by shading measures. When the total amount of ozone dosage was lower than 1.4 mg/L, the coagulation sedimentation tank and activated carbon filtration had excellent effect on bromate removal, and the two?stage dosage of ozone had lower risk of exceeding the standard of bromate than that of single stage dosage.
