厌氧氨氧化菌固定化技术及其研究进展

Gongye shui chuli
厌氧氨氧化因其低能耗和高效脱氮而受到广泛关注，该技术在处理高氨氮、低碳氮比废水方面具有极大的应用价值。然而，自养型厌氧氨氧化菌倍增速度缓慢，污泥容易流失，且对生长环境的要求非常严格，导致厌氧氨氧化脱氮技术的应用受到限制。笔者总结了目前主要的4种厌氧氨氧化菌固定化技术的原理、优缺点以及适用场景，阐述了厌氧氨氧化菌固定化技术的最新研究进展，介绍了厌氧氨氧化菌的不同载体材料，并对厌氧氨氧化菌固定化技术的关键影响因素和最佳应用条件进行了总结 ...

磷酸盐矿物固铀法处理含铀废水研究现状与进展

Gongye shui chuli
铀矿及铀-多金属矿采冶过程产生的含铀废水的无害化与资源化是核资源与环境领域的研究热点。综述了磷酸盐矿物固铀法处理含铀废水的研究现状与进展，介绍了可溶磷酸盐固铀、含磷天然矿物固铀、人工合成磷酸盐吸附材料固铀、生物介导有机磷固铀的固化原理及效果。相较于其他矿物固铀工艺，磷酸盐矿物固铀具有效率高、成本低、产物稳定性强的优点。磷酸盐固铀过程中，金属阳离子种类决定着固铀成矿过程及产物种类，在众多金属磷酸盐固铀矿物中，变钙铀云母的溶解稳定性最高，这为磷酸盐矿物固铀法在低浓度含铀溶液中铀的脱除与回收提供了新的思路。
