摘要
为评估双氧水在给水厂深度处理改造中的应用潜力,依托中试装置分析了臭氧/双氧水/活性炭工艺中氧化剂投加量和投加比对工艺处理效能的影响,结果表明:与臭氧/活性炭工艺相比,臭氧/双氧水/活性炭工艺对中试装置进水中的COD_(Mn)、土臭素、2-MIB、甲砜霉素和氟甲砜霉素均有更高的去除率,且对于水中富里酸类物质、溶解性微生物代谢产物及自生源组分的削减幅度更大,试验条件下的最优工况为O_(3)投加量1.0 mg/L,O_(3)/H_(2)O_(2)质量比2∶1。在水厂常规的臭氧投加规模下(0.5~1.5 mg/L),臭氧/双氧水/活性炭工艺出水基本没有双氧水残留的问题。
In order to evaluate the application potential of H_(2)O_(2)in the advanced treatment of water plant,effects of oxidant dosage and mass ratio on the O_(3)/H_(2)O_(2)/Activated carbon treatment efficiency were analyzed by pilot tests.The results show that compared with O_(3)/Activated carbon treatment process,O3/H_(2)O_(2)/Activated carbon treatment process has a higher removal rate of COD_(Mn),Geosmin,2-MIB,Thiamphenicol and Florfenicol,and the reduction of Fulvic Acid-like,soluble microbial by-product-like and endogenous biological DOM is more efficient.When the O_(3)dosage was 1 mg/L and the O_(3)/H_(2)O_(2)mass ratio was 2∶1,The test reached the optimum condition.Under the conventional ozone dosages of water plant(0.5~1.5 mg/L),there is little need to worry about residue of H_(2)O_(2)in the effluent of O3/H_(2)O_(2)/Activated carbon advanced process.
