基于O_3/H_2O_2处理船舶压载水过程中形成溴酸盐的研究
|
摘要
船舶压载水异地排放会引发外来生物入侵,而在船舶压载水处理过程中,在杀灭有害生物的同时也会产生致癌性有毒化学副产物。文章主要研究利用O_3/H_2O_2处理船舶压载水过程中溴酸盐的生成,并考察了温度、pH、溴离子浓度、H_2O_2/O_3摩尔比对其生成过程的影响。结果表明:溴酸盐含量随温度升高而降低,随溴离子含量的增加而升高,随pH值增加而增加,H_2O_2/O_3摩尔比存在一个最佳范围0.5～1.0。结合研究结果,从工程实际出发,建议处理后的船舶压载水采用中和处理手段以降低对海洋环境的负面影响。
Ballast water discharges lead to nonindigenous species introduced to marine ecosystems. During the ballast water treatment procedure, many harmful chemical by-products are formed while harmful species are killed. The paper mainly studies the bromate formation from ballast water treatment by O_3/H_2O_2 process, along with the influence of temperature, pH, bromide initial concentrations and H_2O_2/O_3 molo ratio on the formation.The results indicate that bromate concentrations decreases with increasing temperature. An increase in bromide concentrations and p H enhances the formation of bromate. The optimal H_2O_2/O_3 molo ratio is 0.5～1.0.Combining with the study result, from the engineering practice, it suggests that treated ballast water should be neutralized prior to discharge to reduce the adverse impact to marine ecosystem.
