摘要:
利用消毒副产物（DBPs）三卤甲烷生成势（THMsFP）和卤乙酸生成势（HAAsFP），研究了含溴污水在某校园污水处理工艺中沿程DBPs前体物变化及溴离子对DBPs类型的影响规律。结果表明，以A2/O生物工艺为主的二级处理，对污水中DOC、UV254的去除效果十分显著，THMsFP在沿程处理中呈逐渐降低的趋势，HAAsFP与SUVA值经二级处理后呈升高趋势，即芳香性与不饱和度高的溶解性小分子有机物是HAAs的重要前体物，含溴消毒副产物（Br-DBPs）占总DBPs的50%~65%；经A2/O工艺处理后，当Br-浓度由100 μg/L增加到300 μg/L时，THMs中溴结合因子（BIF）由0.5增加到0.8，HAAs中BIF由0.51增加到0.62，溴代为主的THMsFP和HAAsFP呈逐渐增加的趋势，即溴离子浓度的增加使DBPs的种类由氯代向溴代转化。
Abstract:
The changes in disinfection by?products (DBPs) precursors and the effect of bromide ion on DBPs types in bromide?containing wastewater from a campus wastewater treatment process were investigated by using the formation potentials of two DBPs:trihalomethane formation potential (THMsFP) and haloacetic acid formation potential (HAAsFP). The secondary treatment based on A2/O process had a good removal performance of DOC and UV254 in wastewater. Profile of the concentration of THMsFP was a decreasing trend along the treatment process, whereas the profile of the concentrations of HAAsFP and SUVA was an increasing trend after secondary treatment. Therefore, soluble small molecular organics with high aromaticity and desaturation were important precursors of HAAs, and bromide?containing disinfection by?products (Br-DBPs) accounted for 50%-65% of the total DBPs. After A2/O treatment,with the increasing of bromide ion concentration from 100 ?g/L to 300 ?g/L, bromide?binding factor (BIF) of THMs increased from 0.5 to 0.8, and the BIF of HAAs increased from 0.51 to 0.62. The concentration of dominated bromide, THMsFP and HAAsFP, showed a trend of gradual increase, that was, the increase of bromide ion concentration transformed DBPs from chlorides to bromides.
