“…Compared with other treatment methods, biological treatment has the advantages of low cost and less secondary pollution. At present, most of the research focuses on finding suitable bacteria, exploring combination technologies based on biological treatment and optimizing process (Yang, Lin, et al, 2018). Wang and Wang (2018c) investigated the degradation of six new organic pollutants, including carbamazepine, trimethoprim, diclofenac, sulfamethoxazole, triclosan, and methyl 3,5-dichloro-4-hydroxybenzoate, by acclimated activated sludge (AAS).…”

Recently, emerging pollutants (EPs) have been frequently detected in urban wastewater, surface water, drinking water, and other water bodies. EPs mainly usually include pharmaceuticals and personal care products, endocrine-disrupting chemicals, antibiotic resistance genes, persistent organic pollutants, disinfection by-products, and other industrial chemicals. The potential threat of EPs to ecosystems and human health has attracted worldwide attention. Therefore, how to treat EPs in various water bodies has become one of the research priorities. In this paper, some research results on treatment of EPs published in 2018 were summarized.

“…Acidovorax species has a positive correlation with synchronous nitri cation and denitri cation (SND), with the correlation coe cient r 2 reaching 0.771, and the bacteria has been found to have a certain degree of synchronous nitri cation and denitri cation (Moura et al, 2018). Acinetobacter has a certain negative in uence on the simultaneous nitri cation and denitri cation, with a correlation coe cient of -0.886, although the bacteria has been found to be generally good at denitri cation (Yang et al, 2018), it is also closely related to the degradation of organic matter (Vijayalayan et al, 2014). However, in this experiment, Acinetobacter showed the phenomenon of inhibiting the simultaneous nitri cation and denitri cation.…”

Swine wastewater (SW) poses a great threat to the environment due to its high-nutrient pro les if not properly managed. Advanced biological treatment method is an e cient method to treat SW by screening potent microalgae or bacterial strains. In this study, activated sludge, nine locally isolated heterotrophic nitri cation bacteria and one microalgal strain (Chlorella) were used as inoculums in treating a local SW.Their treatment e ciencies were compared, while the nitrogen removal mechanisms and microbiome pro le were explored in detail. It was found that certain heterotrophic nitri cation strains had a slight advantage in removing chemical oxygen demand and phosphorus from SW, with the highest removal e ciencies of 83.9% and 76.2%, respectively. The removal e ciencies of ammonia nitrogen and total nitrogen in wastewater by microalgae reached 80.9% and 66.0% respectively, which were far higher than all the heterotrophic nitri cation strains. Biological assimilation was the main pathway of nitrogen conversion by microalgae and heterotrophic nitrifying bacteria; especially microalgae showed excellent biological assimilation performance. Correlation analysis showed that Comamonas was highly positively correlated with nitrogen assimilation, while Acidovorax was closely correlated with simultaneous nitri cation and denitri cation. This study gives a comparison of microalgae and heterotrophic nitrifying bacteria on the nitrogen transfer and transformation pathways.

“…High strength wastewaters such as those produced by intensive animal husbandry represent a severe environmental problem that is also limiting the growth of this economic sector in Europe. Piggery wastewater (PWW) is characterized by a high content of particulate and dissolved organic carbon, nitrogen (mainly in the form of NH4 + ) and phosphorous due to the limited use of water during farming [1][2][3], which can severely damage water bodies and soil if not properly managed [4]. In this context, photosynthetic microorganisms have been proposed as cost-effective platforms for the removal of nutrients and carbon from PWW [3,[5][6][7][8][9].…”

Purple phototrophic bacteria (PPB) represent an innovative approach for wastewater treatment with a high metabolic plasticity, able to grow under aerobic and anaerobic conditions. This study comparatively assessed the long-term performance (450 days of operation) of an open and closed PPB-based photobioreactor treating of piggery wastewater (PWW). The influence of wastewater dilution, illuminated area to volume ratio, biomass settling and recirculation, and infrared light intensity on wastewater treatment was evaluated at 7 days of hydraulic retention time. An increase in PWW dilution from 4 to 8 folds did not entail higher TOC removal efficiencies (REs) in the open photobioreactor (87% versus 89%), but a significant increase in the closed photobioreactor (from 73% to 80%). The increase in the illuminated area to volume ratio increased TN-REs up to 99% and 49% in the open and closed photobioreactor, respectively, with a concomitant increase in the temperature of both systems. However, temperature control did not mediate a significant enhancement in PWW treatment.Biomass settling and recirculation resulted in higher TN-REs (80%) and TOC-REs (90%) in the closed photobioreactor. The increase in infrared radiation from 100 to 300 W m -2 fostered PPB growth. High water evaporation losses (deteriorating effluent quality) were recorded in the open photobioreactor, where carbon dioxide and ammonia stripping were identified as the main pathways supporting carbon and nitrogen removal.
