Advanced treatment of oil recovery wastewater from polymer flooding by UV/H2O2/O3 and fine filtration

In order to purify oil recovery wastewater from polymer flooding （ORWPF） in tertiary oil recovery in oil fields, advanced treatment of UV/H2O2/O3 and fine filtration were investigated. The experimental results showed that polyacrylamide and oil remaining in ORWPF after the conventional treatment process could be effectively removed by UV/H2O2/O3 process. Fine filtration gave a high performance in eliminating suspended solids. The treated ORWPF can meet the quality requirement of the wastewater-bearing polymer injection in oilfield and be safely re-injected into oil reservoirs for oil recovery.     

Removal of lead from aqueous solutions by condensed tannin gel adsorbent

Lead has caused serious environmental pollution due to its toxicity, accumulation in food chains and persistence in nature.In this paper, lead removal from aqueous solutions was investigated using condensed tannin gel adsorbent synthesized from a natural tannin compound. It is found that the adsorption is strongly affected by pH values of aqueous solutions.Within pH range of 3.5-6,when initial lead concentration is 100 mg/L, removal efficiency is more than 90%.Adsorption equilibrium is reached within 150 minutes.The adsorption isotherm fits well with the Langmuir equation, by which the saturated adsorption uptake of 190 mg Pb^2 /g dry tannin gel adsorbent is obtained.By means of thermodynamics analysis,it is revealed that the process is exothermic and the adsorption heat is up to 38.4kJ/mol.With respect to high efficiency, moderate pH requirement and minimized second pollution, the tannin gel adsorbent exhibits a promising potential in the removal of lead from wastewater.

膜表面污染中凝胶层形成机理及控制的研究

膜污染问题是影响膜生物反应器发展的一项关键技术。文章对膜污染中凝胶层的产生机理进行了研究与分析，认为凝胶层形成首先是由有机物在膜表面的吸附开始．在膜面浓差极化、生物污染及膜孔堵塞影响的共同作用下，使凝胶层迅速增厚，从而导致膜的严重污染；文章还对膜污染的控制进行了研究分析。     

聚合物在沉淀法处理氨氮废水中的助凝作用

在采用化学沉淀法处理氨氮废水时,添加聚合物能提高了悬浮物的效率,从而节约了沉淀剂的使用量降低了处理成本.研究考查在沉淀剂中添加聚丙烯酰胺(PAM)、聚合氯化铝(PAc)对氨氮去除的影响.结果表明:在pH值为9.3,主要离子的物质量之比为1:1:1、聚丙烯酰胺添加量为20mg/L或聚合氯化铝添加量为200mg/L的条件下,处理初始浓度为1000mg/L的氨氮废水,均可使氨氮去除率可达到99%以上,PAM和PAC的助凝作用综合比较,添加20mg/L可以使氨氮率较未加入时提高5.38%.
