摘要
采用臭氧活性炭联合工艺(O3+BAC)对以长江为水源的某水厂砂滤水进行深度处理。试验结果表明,该工艺对水中有机物有稳定的去除效果,在臭氧投加量为1mg/L,活性炭空床接触时间为8.6min时,对CODMn,UV254,DOC,THMEP(三氯甲烷生成势)和AOC(可同化有机碳)的平均去除率分别为32%,40%,22%,19%,7%。在DOC较低的情况下,三氯甲烷生成势与UV254有较好的正相关性。
An ozone-active carbon (O3 + BAC) combined process was used in the deep treatment of the sand-filtered water in a water plant using Yangtze River as its water source. The result of the test shows that this process has a stable removing effect on the organic matters in the water. When the dosage of ozone was 1 mg/L and the empty bed contact time(EBCT) of active carbon was 8.6 min, the average removal rates of CODMn, UV254, DOC(dissoluble organic carbon), THMEP(generation potential of chloroform)and AOC(assimilable organic carbon)were 32%, 40%, 22%, 19% and 7% respectively. It is also showed that when DOC is relatively low, a good positive correlativity exists between the generation potential of chloroform and the UV254.
