摘要:針對(duì)垃圾滲濾液厭氧氨氧化出水中有機(jī)物殘留的問題,提出了“混凝—氣浮—高級(jí)氧化”的無膜法工藝改造路線,并對(duì)混凝過程進(jìn)行了深入研究;考察了混凝劑種類和投加量、pH等對(duì)有機(jī)物去除的影響,并進(jìn)行中型正交試驗(yàn);另外還分析了混凝前后有機(jī)物的變化以及壓濾脫水后混凝污泥中有機(jī)物的釋放規(guī)律;炷に嚨淖罴褩l件如下:pH=5.75、聚合硫酸鐵(PFS)投加量為1 500 mg/L、聚丙烯酰胺(PAM)投加量為2 mg/L,在此條件下TOC、COD、UV254和色度的去除率分別可達(dá)到79.84%、67.57%、88.55%和95.00%;中型正交試驗(yàn)結(jié)果表明,對(duì)混凝工藝影響最大的因素是pH,混凝工藝最佳條件與小試結(jié)果一致,證明該試驗(yàn)結(jié)果放大可信;三維熒光數(shù)據(jù)分析表明,混凝幾乎去除了全部的腐殖酸;凝膠滲透層析(GPC)結(jié)果表明,處理后有機(jī)物的分子質(zhì)量整體變小;另外,混凝污泥的有機(jī)物釋放量較小且釋放速率逐漸趨于穩(wěn)定,污染物二次釋放的風(fēng)險(xiǎn)較小。
Abstract:This paper proposed a non-membrane process consisting of coagulation, air floatation and advanced oxidation, and investigated the coagulation process, so as to solve the problem of organic residues in the effluent from anaerobic ammonia oxidation for treating landfill leachate. The effects of factors such as coagulant type, coagulant dosage and pH on the removal of organic matter were investigated, and an pilot-scale orthogonal test was carried out. In addition, the change of organic matter before and after coagulation and the release characteristics of organic matter in coagulated sludge after pressure filtration dehydration were also analyzed. The optimal coagulation process were as follows: the pH was 5.75, the dosage of polymerized ferric sulfate (PFS) was 1 500 mg/L and the dosage of polyacrylamide (PAM) was 2 mg/L. Under these conditions, the removal rates of TOC, COD, UV254 and chroma reached 79.84%, 67.57%, 88.55% and 95.00%, respectively. The pilot-scale orthogonal test results showed that pH was the most important factor affecting the coagulation process, and the optimal operating conditions were consistent with the bench-scale test results, which proved that the experimental results were reliable. The three-dimensional fluorescence data showed that coagulation removed almost all of the humic acid. The results of gel permeation chromatography (GPC) showed that the molecular weight of organic matter decreased after coagulation treatment. In addition, the amount of organic matter released from the coagulated sludge was small and the release rate gradually tended to be stable, indicating that the risk of pollutants secondary release was small.
