【摘要】：目前國內(nèi)對含汞廢水的處理主要采用硫化法-絮凝法,不但造成藥劑的浪費及處理不達標,產(chǎn)生的含汞污泥也難以處理,造成二次污染;而且對汞離子去除效果較好。但新疆氣田水經(jīng)分析主要為懸浮汞和單質(zhì)汞,存在少量離子汞和有機汞。吸附過濾除氣田污水中汞的技術是目前最具有應用前景的。以多孔聚酰胺、改性殼聚糖和聚合硅酸鋁為原料,制備出具有單質(zhì)汞優(yōu)異吸附性能和吸附選擇性的納米復合型材料;并配合適當?shù)难b置和工藝處理后氣田污水中汞濃度能夠穩(wěn)定在5×10~(-9)(ppb)以下;而且操作簡便、處理成本低。
[Abstract]:At present, the main treatment of mercury-containing wastewater in China is vulcanization-flocculation process, which not only results in waste of medicament and substandard treatment, but also makes it difficult to treat mercury-containing sludge, resulting in secondary pollution. But the water of Xinjiang gas field is mainly suspended mercury and elemental mercury. There are a small amount of ionic mercury and organic mercury. The technology of adsorption and filtration of mercury in gas field wastewater is the most promising. Porous polyamide, modified chitosan and polymeric aluminum silicate are used as raw materials. Nano-composite materials with excellent adsorption performance and adsorption selectivity of mercury were prepared. The mercury concentration in the waste water of the gas field can be stabilized below 5 脳 10 ~ (-9) (ppb) after the gas field wastewater is treated with appropriate equipment and process. Moreover, the operation is simple and the processing cost is low.

【正文快照】： 隨著含汞天然氣的開發(fā),含汞氣田水可能破壞生態(tài)環(huán)境,危害操作人員健康并影響正常生產(chǎn)[1]。目前國內(nèi)含汞污水脫汞技術使用最多的是硫化物沉淀法,并輔以絮凝劑增加沉淀物的脫除效果,進而提高汞的去除率[2,3]。但這種方法主要是脫除水中的無機和有機離子汞[1],不適用于單體汞;而，
