Autonomous underwater unmanned platforms have become important facilities in the marine field since countries attach importance to maritime rights and interests, and play an important role in both military and civilian use. However, complex underwater marine environmental elements will have a huge impact on the performance of underwater unmanned platforms, and how to ensure the safe and stable operation of underwater unmanned platforms has become an urgent problem to be solved. Based on this practical problem, this paper studies the influence of marine environmental elements on the operation of underwater unmanned platforms with reference to the hydrological data of the South China Sea, and uses Bayesian methods to carry out risk zoning of the impact of the marine environment in the South China Sea on underwater unmanned platforms. © Published under licence by IOP Publishing Ltd.

Recovery of phosphorus from chemical-enhanced phosphorus removal sludge: Influence of sodium sulfide dosage on phosphorus fractionation, sludge dewaterability, and struvite product

Despite the potential of sodium sulfide (Na2S) for phosphorus (P) recovery from iron-phosphate waste, the underlying mechanism regarding its impact on P conversion and product quality has not been well addressed. In this study, the effects of Na2S addition on P release and recovery from a chemical-enhanced phosphorus removal (CEPR) sludge during anaerobic fermentation were systematically investigated. The results revealed that the effective mobilization of P bound to Fe (Fe–P) by Na2S dominated the massive P release from the CEPR sludge, while the organic P (OP) release was not significantly enhanced during anaerobic fermentation. Due to the rapid reaction of Na2S with Fe–P and the prevention of Fe(II)–P precipitation by excess S2−, the Fe–P was decreased by 9.7%, 15.2% and 24.9% at S:Fe molar ratios of 0.3, 0.5 and 1, respectively. After anaerobic fermentation, the released P mainly existed as soluble phosphate (SP), P bound to Ca (Ca–P) and P bound to Al (Al–P). The nitrogen and P contents in the fermentation supernatant significantly increased with higher S:Fe ratios, facilitating the efficient recovery of P as high-purity struvite. However, the increased Na2S dosage deteriorated the sludge dewaterability because of the dissolution of hydrophilic extracellular polymeric substances and the looser secondary structure of proteins. Comprehensively considering the P recovery, sludge dewaterability and economic cost, the optimal Na2S dosage was determined at the S:Fe ratio of 0.3. These findings provide novel insights into the role of Na2S in P recovery as struvite from CEPR sludge. © 2024 Elsevier Ltd

Algal blooms are regarded as a significant source of CH4 emissions. Ultrasound has been gradually employed as a fast and efficient algae removal technology in recent years. However, the changes in water environment and potential ecological effects caused by ultrasonic algae removal are not fully clear. Here, a 40-day microcosm study was performed to simulate the collapse of Microcystis aeruginosa blooms after ultrasonic treatment. The results showed that low-frequency ultrasound at 29.4 kHz for 15 min removed 33.49% of M. aeruginosa and contributed to the destruction of cell structure, but it intensified the leakage of intracellular algal organic matter and microcystins. The accelerated collapse of M. aeruginosa blooms after ultrasonication promoted the rapid formation of anaerobic and reductive methanogenesis conditions, and elevated dissolved organic carbon content. Moreover, the release of labile organics, including tyrosine, tryptophan, protein-like compositions, and aromatic proteins, was facilitated by the collapse of M. aeruginosa blooms after ultrasonic treatment, and they supported the growth of anaerobic fermentation bacteria and hydrogenotrophic Methanobacteriales. This was also demonstrated by the increase in methyl-coenzyme M reductase (mcrA) genes in sonicated algae added treatments at the end of incubation. Finally, the CH4 production in sonicated algae added treatments was 1.43-fold higher than that in non-sonicated algae added treatments. These observations suggested that ultrasound for algal bloom control potentially increased the toxicity of treated water and its greenhouse gas emissions. This study can provide new insights and guidance to evaluate environmental effects of ultrasonic algae removal. © 2023, The Authors. All rights reserved.

Challenging the contamination of per- and polyfluoroalkyl substances in water: advanced oxidation or reduction?

Environmental Functional Materials

Environmental Functional Materials 2022年第3期1卷 325-337页

Nowadays, the increasing discharge of persistent per- and polyfluoroalkyl substances (PFASs) caused serious environmental issues. In addition to advanced oxidation processes (AOPs), advanced reduction processes (ARPs) based on reducing radicals, e.g., hydrated electron and superoxide anions have attracted great attentions as promising methods for remediation of PFASs pollution. This review, based on 128 cited references, provides a critical overview on the performance of different AOPs and ARPs. The unique properties of reactive species, e.g., SO 4 •- and e aq − and their generation mechanisms in different systems were discussed. Moreover, the efficiencies of different systems were further compared from several aspects, e.g., PFASs decomposition rate, reaction time and energy consumption. More specially, for some model compounds of PFASs, such as perfluorooctanoic acid, perfluorooctane sulfonate and perfluoroalkyl ether carboxylic acids, we systematically discussed their degradation and defluorination pathways in both AOPs and ARPs. The reported literatures showed that the degradation pathways of these PFASs are closely related to their head groups in either AOPs or ARPs. Finally, some key conclusions were summarized, and the implications of the state-of-the-art knowledge on practical PFASs remediation in water treatments were summarized and the future priority research directions were proposed.

Characterization and source apportionment of pharmaceuticals in surface water of the Yangtze Estuary and adjacent sea

Pharmaceuticals, which are closely linked to human activities, have attracted global attention. This study investigated the occurrence characteristics of 20 pharmaceuticals in surface water of the Yangtze Estuary and adjacent sea. A total of 14 targeted pharmaceuticals were detected in both spring and summer sampling campaigns. The mean concentrations of sulfonamides and non-sulfonamides were 36.60 ± 19.43 ng·L−1 and 50.02 ± 41.07 ng·L−1, respectively. As for non-antibiotics, their concentrations were in the range of 24.34 ± 916.8 ng·L−1 with caffeine accounting for 6.17 ~ 86.70% (average percentage of 42.22%). Meanwhile, spatial distribution patterns showed similarities between antibiotics and non-antibiotics, with high levels occurring near the upper estuary, aquaculture areas, wastewater treatment plants, and the maximum turbidity zone. This phenomenon could be related to the sources of pharmaceuticals and the physicochemical properties of water bodies. Obviously, the first three areas are highly impacted by human activities or serve as important sources of terrestrial contaminants entering the East China Sea. The last area retains high amounts of suspended particles which may exert strong trapping effects on hydrophobic chemicals. Principal component analysis revealed the presence of three potential sources for pharmaceuticals in the Yangtze Estuary, with a relatively high percentage originating from incompletely treated municipal sewage. As for the temporal trend, pharmaceutical contamination was found to be higher in spring compared to summer, potentially due to variations in pharmaceutical consumption patterns, local rainfalls, and water temperatures. These findings provide fundamental data support for implementing appropriate local management strategies for pharmaceutical usages. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
