摘要:針對污水處理廠污泥脫水難度大的問題，采用綠色合成納米鐵(GS-Fe-NPs)/H2O2類芬頓試劑聯(lián)合兩性高分子污泥脫水劑調(diào)理污泥�？疾炝薍2O2投加量、初始pH值、溫度、反應(yīng)時間和GS-Fe-NPs投加量對類芬頓氧化調(diào)理污泥的影響。結(jié)果表明，當(dāng)污泥初始pH值為6.82（未經(jīng)調(diào)節(jié)）、H2O2和GS-Fe--NPs的投加量分別為3.0和1.0 g/L、溫度為20 ℃、反應(yīng)時間為1 h時，離心后污泥含水率可降至70.3%；經(jīng)調(diào)理后污泥上清液中的溶解性化學(xué)需氧量（SCOD）、多糖和蛋白質(zhì)分別增加了8.8、13.2和13.9倍，表明胞外聚合物（EPS）得到了有效破解；相同操作條件下,3個處理系統(tǒng)中羥基自由基(·OH)的相對含量從大到小依次為：GS-Fe-NPs/H2O2>納米零價鐵(nZVI)/H2O2>Fe2+/H2O2，可見GS-Fe-NPs/H2O2體系具有更強的氧化能力。向氧化調(diào)理后的污泥中投加脫水劑PADS,可以進(jìn)一步有效改善污泥的脫水性能。
Abstract:Aiming at the difficult problem of sludge dewatering in wastewater treatment plants, Fenton-like reagent［green synthetic iron nanoparitcles (GS-Fe-NPs)/H2O2］ combined with amphoteric polymer sludge dewatering agent was used to condition the sludge.The influences of?H2O2 dosage, initial pH value, temperature, reaction time and?GS-Fe-NPs dosage on conditioning of sludge by the Fentonlike oxidization were investigated. When sludge initial pH was 6.82 (not adjusted), dosages of?GS-Fe-NPs and?H2O2 were 1.0 g/L and 3.0 g/L, temperature was 20 ℃ and reaction time was 1 hour, the sludge water content could be reduced to 70.3% after centrifugation. At the same time, the soluble COD (SCOD), polysaccharide and protein in the sludge supernatant increased by 8.8, 13.2 and 13.9 times respectively after conditioning, indicating that extracellular polymeric substance (EPS) of the sludge was effectively destroyed. Under the same operational conditions, the relative contents of hydroxyl radical (·OH) in the three treatment systems were measured, and the relative content from large to small wasGS-Fe-NPs/H2O2>nZVI/H2O2>Fe2+/H2O2, suggesting that the system of GS-Fe-NPs/H2O2 had the strongest oxidation capacity. It could further improve the dewatering performance of sludge effectively by adding dewatering agent PADS to the conditioned sludge.
