摘要： A method for treatment of wastewater includes passing influent wastewater through an anaerobic, anoxic, or bioelectrochemical bioreactor to produce an effluent. The membrane bioreactor includes a membrane with pores having a nominal pore size less than the smallest measured biopolymers and organic nanoparticles in the influent wastewater, thereby preventing them from entering and blocking membrane pores, and further comprising degrading dissolved organics smaller than 20 nm in the influent wastewater within the membrane bioreactor before entering membrane pores.

摘要： A microbial battery is provided. At the anode, microbial activity provides electrons to an external circuit. The cathode is a solid state composition capable of receiving the electrons from the external circuit and changing from an oxidized cathode composition to a reduced cathode composition. Thus, no external source of oxygen is needed at the cathode, unlike conventional microbial fuel cells. The cathode can be removed from the microbial battery, re-oxidized in a separate oxidation process, and then replaced in the microbial battery. This regeneration of the cathode amounts to recharging the microbial battery.

摘要： New multifunctional synthetic nanoparticles are adapted for water treatment, with environmentally-functional layers, optional capping layers, and synthetic antiferromagnetic cores. With high surface-to-volume ratio, these nanoparticles are very efficient in water treatment, including but not restricted to water disinfection, photo-catalytic degradation, contaminant adsorption, etc., in the context of drinking water or waste water treatment. Meanwhile, their magnetic cores are highly magnetically responsive and can be separated by 99% within 10 min using simply a permanent magnet. Moreover, once some non-degradable chemicals (like perfluorinated compounds) are absorbed to the particle surface, these chemicals can be further degraded by introducing hyperthermia or eddy current heating. These particles can be redispersed after the external magnetic field is removed, and can therefore be used in a regenerative treatment process, substantially reducing the cost while eliminating contaminated byproducts.
摘要翻译： 新的多功能合成纳米颗粒适用于水处理，具有环境功能层，可选的封盖层和合成的反铁磁芯。 具有高的表面体积比，这些纳米颗粒在水处理中是非常有效的，包括但不限于在饮用水或废水处理的情况下的水消毒，光催化降解，污染物吸附等。 同时，它们的磁芯具有高度的磁响应能力，可以在10分钟内使用简单的永久磁铁分离99％。 此外，一旦将一些不可降解的化学物质（如全氟化合物）吸收到颗粒表面，则通过引入热疗或涡流加热可以进一步降解这些化学物质。 这些颗粒在除去外部磁场后可以再分散，因此可以用于再生处理过程中，大大降低成本，同时消除被污染的副产物。
