Aquatic plants have great potentials for simultaneous sewage treatment and nutrients recovery. Herein, six aquatic plants (Alternanthera philoxeroides [A. philoxeroides], Pistia stratiotes, Eichhornia crassipe, Salvinia natans, Ludwigia adscendens and Myriophyllum aquaticum) were comprehensive evaluated through 15 qualitative and quantitative indicators. According to the evaluation system established using the Analytic Hierarchy Process, A. philoxeroides exhibited the best comprehensive performance. Further analyses revealed that A. philoxeroides showed good growth status and sewage treatment ...

The potential of microalgae in wastewater treatment and resource utilization has received considerable interest. For better outcomes in large-scale cultivations, it is usually essential to optimize the microalgal culture parameters in a sub-pilot cultivation system. Herein, a series of experiments were carried out to investigate the effects of photoperiod, CO2 concentration and aeration intensity on nutrients removal and biomass production of Tetradesmus dimorphus under the 50 L culture scale. The results showed that the removal rates of chemical oxygen demand (CODcr), NH4+-N and total phospho...
