【摘要】：分析水廠生物活性炭工藝和膜工藝各工藝段的出水水質(zhì),發(fā)現(xiàn)兩種飲用水處理工藝均能對濁度達到99%以上的去除率,對UV254總?cè)コ史謩e為29%和26%,對總有機碳的總?cè)コ史謩e為49%和42%,高錳酸鹽指數(shù)總?cè)コ蕿?8%和26%,對氨氮和總氮去除效果較差。不同分子量范圍占峰面積也不相同,把所測結(jié)果分為10KDa、1K-10KDa和1KDa三種范圍。對比兩種工藝各工藝段出水中有機物分子量分布特性和有機物種類變化可知,兩種工藝對1K-10KDa分子量有機物均能有效去除,去除率分別為26%和34%,且膜工藝對1KDa分子量有機物控制效果較好。兩種工藝中原水含有一定程度的氯代有機物、不同種類的芳香烴和烷烴,種類較多。生物活性炭工藝中砂濾工藝段,膜工藝中混凝沉淀與膜1、膜2、膜、膜4工藝段均能有效控制有機物種類,消毒后出水中有機物種類有一定增加。兩種工藝除消毒后出水外各工藝段氯代消毒副產(chǎn)物濃度較低,兩種工藝中原水中鹵乙酸和氯仿濃度分別為8.5μg/L和1.5μg/L,經(jīng)消毒后出水氯代消毒副產(chǎn)物濃度增加,生物活性炭工藝消毒后出水鹵乙酸和氯仿濃度分別為15.5μg/L和2.9μg/L,膜工藝分別為10.4μg/L和2.8μg/L,氯消毒對消毒副產(chǎn)物的生成有重要影響。另外,膜工藝對鹵乙酸和氯仿的控制作用優(yōu)于生物活性炭工藝。生物活性炭工藝和膜工藝中原水生成潛勢最高,鹵乙酸生成潛勢分別為194.8μg/L和1931μg/L,氯仿生成潛勢濃度分別為105.2μg/L和107.3μg/L,其它工藝段出水生成潛勢變化不大,生物活性炭工藝段微生物的代謝生長也對生成潛勢有一定的影響。
[Abstract]:The effluent quality of biological activated carbon (BAC) process and membrane process were analyzed. It was found that the turbidity could be removed more than 99% by the two drinking water treatment processes. The total removal rate of UV254 was 29% and 26, the total removal rate of total organic carbon was 49% and 42, the total removal rate of permanganate index was 28% and 26, and the removal efficiency of ammonia nitrogen and total nitrogen was poor. The measured results were divided into three ranges: 10K Dawei 1K-10KDa and 1KDa. By comparing the molecular weight distribution characteristics of organic matter and the variety of organic compounds in the effluent of each process, it can be seen that the two processes can effectively remove 1K-10KDa molecular weight organic matter. The removal rates were 26% and 34, respectively, and the membrane process had better control effect on 1KDa molecular weight organic compounds. The raw water of the two processes contained a certain degree of chlorinated organic compounds, different kinds of aromatic hydrocarbons and alkanes. In the biological activated carbon process, sand filtration process, coagulation sedimentation and membrane 1, membrane 2, membrane 4 process can effectively control the kinds of organic matter. After disinfection, the kinds of organic compounds in the effluent increased to a certain extent, and the concentration of chlorinated disinfection by-products in the two processes was lower than that in the effluent after disinfection. The concentrations of haloacetic acid and chloroform in raw water were 8.5 渭 g / L and 1.5 渭 g / L, respectively. The concentrations of haloacetic acid and chloroform were 15.5 渭 g / L and 2.9 渭 g / L, respectively, and those of membrane process were 10.4 渭 g / L and 2.8 渭 g / L, respectively. Chlorine disinfection had an important effect on the formation of disinfection by-products. The control effect of membrane process on haloacetic acid and chloroform is superior to that of biological activated carbon process. The potential of raw water formation is the highest in biological activated carbon process and membrane process. Halogenoacetic acid formation potential was 194.8 渭 g / L and 1931 渭 g / L, chloroform formation potential concentration was 105.2 渭 g / L and 107.3 渭 g / L, respectively.
