【摘要】：通過(guò)在好氧顆粒污泥培養(yǎng)過(guò)程中分別在第1~7天和第8~14天投加聚合氯化鋁(PAC)的方式,分析顆粒的形成過(guò)程,并研究胞外聚合物總量及其各組分的含量變化和空間分布。研究發(fā)現(xiàn):第8~14天投加PAC的反應(yīng)器形成顆粒時(shí)間提前了6天,且形成的顆粒外形規(guī)則,大小均勻,去除污染物性能良好;反應(yīng)器中胞外多聚物和蛋白質(zhì)含量總體較多,且隨顆粒的形成而增加,之后略有下降并在顆粒成熟后維持穩(wěn)定,蛋白質(zhì)/多糖的值在顆粒形成期均增加超過(guò)2.5倍,有利于顆粒污泥的形成;多重?zé)晒馊旧砻?兩個(gè)反應(yīng)器中PAC投加時(shí)間不同,β-D-呋喃葡萄糖、脂類和活細(xì)胞均呈現(xiàn)不同的分布情況,但對(duì)蛋白質(zhì)和α-呋喃葡萄糖、α-甘露糖分布的影響較小。
[Abstract]:The formation process of polyaluminum chloride (PAC) was analyzed by adding PAC on the 1st and 814 days during aerobic granular sludge culture, and the total amount of extracellular polymers and the content and spatial distribution of extracellular polymers were studied. The results showed that the particle formation time of the reactor with PAC was 6 days earlier on the 8th day, and the particle shape was regular, the size was uniform, the pollutant removal performance was good, and the extracellular polymer and protein contents were more in the reactor. The content of protein / polysaccharide increased by more than 2.5 times in the granulation stage, which was beneficial to the formation of granular sludge. The results of multiplex fluorescence staining showed that the distribution of 尾 -Dfuran glucose, lipids and living cells was different in the two reactors with different dosing time of PAC, but had little effect on the distribution of protein, 偽 -furan glucose and 偽 -mannose.
