Soil microorganisms play a crucial role in maintaining soil ecosystem health. Their metabolic processes are directly impacted by various environmental stresses caused by the increasing release of chemical pollutants and changes in the physical environment due to rapid societal development. This paper aimed to investigate the mechanisms underlying the changes in soil microbial stress responses under various external environmental stresses. The impact of pollutants on soil ecological structure was analyzed by summarizing the stress response patterns of soil microorganisms to inorganic pollutants, organic pollutants, and extreme physical environmental factors. Additionally, the migration and transformation behaviors of various complex pollutants, facilitated by the involvement of soil microorganisms, were investigated. Moreover, a novel approach was proposed for pollutant control, suggesting that manipulating the external physical field of a certain intensity could guide microbial communities and their functions towards controllable evolution within the soil environment. Therefore, this paper was essential for exploring the diversity of soil microbial stress responses, strategically regulating contaminant transport, mitigating risks associated with soil complexity, and ultimately reshaping soil ecological functions.

Saving Energy in Biological Wastewater Treatment by Using Extremely Low-Frequency Electric Field—Pilot-Scale Study

et al. 2023

The results of a pilot-scale study on the influence of electric field use for stimulating the active sludge in the biological purification tank of a small capacity wastewater treatment plant (up to 600 m3/day) are presented. Through specific comparative chemical tests (DO, COD, N-NH4, and Pt) it was found that, by applying a sinusoidal electric field of 5 Vrms/m at 49.9 Hz on the active sludge suspension, the overall pollutant denitrification process speed is doubled compared with the reference case when no stimulation is used. Also, under identical operating conditions, the residual pollutant content of the biological treatment tank outlet water is reduced approximately three times for COD and approximately two times for N-NH4 and Pt compared to the reference tank. These findings lead to the conclusion that, by stimulating the active sludge microbial activity of the wastewater treatment plants by a sinusoidal electric field of 5 Vrms/m at 49.9 Hz, the time of the biological purification treatment can be reduced by approx. 50%. This leads to a corresponding decrease in energy consumption, which usually represents more than 30% of a wastewater treatment plant’s specific electricity consumption.

More than 50 years have passed since the first studies of microalgae treating effluents were published. Suspended growth of filamentous algae in wastewater ponds has been considered in several publications for over a decade. However, despite all the research efforts and the knowledge generated, the technology is far from being adopted. This review compiles all the publications identified in different databases, which used filamentous algal ponds to remediate varied wastewaters, with the aim of identifying the research needs to allow the technology’s application. The experimental methods and results obtained were extracted and compiled for comparison from 28 relevant studies, in which municipal wastewater and Oedogonium spp. were most used. Most of the studies were performed at a small laboratory scale and for short time periods. There was a remarkable use of effluents with a high degree of pretreatment and more studies focused on the biomass productivity than the treatment performance. It is recommended that future research use wastewater, with minimum intervention, rather than defined nutrient solutions, to assess the potential for wastewater treatment. Transitioning from laboratory to outdoor systems at scale should be a primary aim to further adopt this technology.
