    Abstract In this study, calcined water treatment plant sludge (C-WTPS) was used as a catalyst for peroxymonosulfate (PMS) activation to simultaneously remove Disperse Blue 56 (DB56) and phosphates. Firstly, the performance of the C-WTPS/PMS system was examined for the degradation of DB56. The results showed that 96.7% of DB56 (400 mg L⁻¹) was removed within 60 min in the presence of 4.8 g L⁻¹ PMS and 0.8 g L⁻¹ C-WTPS at pH 3 and 50 °C. Hydroxyl radicals (·OH), sulfate radicals (SO₄·⁻), and singlet oxygen (¹O₂) were generated during the oxidation process, and ¹O₂ was the main active species. The relatively high surface area, proper Fe content, and abundant ketone groups on the catalyst surface were responsible for PMS activation. Furthermore, the possible degradation pathways of DB56 were proposed based on the gas chromatography–mass spectrometry (GC–MS) results. Secondly, the simultaneous removal of DB56 and phosphates by the C-WTPS/PMS system was investigated. Due to the different removal mechanisms, the effects of the initial phosphate concentration and water matrix species on the removal of DB56 and phosphates showed different trends. Reusability tests results showed that C-WTPS had relatively high stability. In addition, the C-WTPS/PMS system exhibited a high decolorization ratio and phosphate removal efficiency in real wastewater tests. This article offers a value-added approach for reusing WTPS as a catalyst for treating organic contaminants and phosphates.

    Abstract In this study, aluminum-based P-inactivation agent (Al-PIA) was used as a high-efficiency microbial carrier, and the biological Al-PIA (BA-PIA) was prepared by artificial aeration. Laboratory static experiments were conducted to study the effect of BA-PIA on reducing nitrogen and phosphorus contents in water. Physicochemical characterization and isotope tracing method were applied to analyze the removal mechanism of nitrogen and phosphorus. High-throughput techniques were used to analyze the characteristic bacterial genus in the BA-PIA system. The nitrogen and phosphorus removal experiment was conducted for 30 days, and the removal rates of NH₄⁺-N, TN and TP by BA-PIA were 81.87%, 66.08% and 87.97%, respectively. The nitrogen removal pathways of BA-PIA were as follows: the nitrification reaction accounted for 59.0% (of which denitrification reaction accounted for 56.4%), microbial assimilation accounted for 18.1%, and the unreacted part accounted for 22.9%. The characteristic bacteria in the BA-PIA system were Streptomyces, Nocardioides, Saccharopolyspora, Nitrosomonas, and Marinobacter. The loading of microorganisms only changed the surface physical properties of Al-PIA (such as specific surface area, pore volume and pore size), without changing its surface chemical properties. The removal mechanism of nitrogen by BA-PIA is the conversion of NH₄⁺-N into NO₂⁻-N and NO₃⁻-N by nitrifying bacteria, which are then reduced to nitrogen-containing gas by aerobic denitrifying bacteria. The phosphorus removal mechanism is that metal compounds (such as Al) on the surface of BA-PIA fix phosphorus through chemisorption processes, such as ligand exchange. Therefore, BA-PIA overcomes the deficiency of Al-PIA with only phosphorus removal ability, and has better application prospects.

    Abstract In this article, dynamic simulation experiments have studied the effects of three capping materials, quartz sand (QS), aluminum-based phosphorus-locking agent (Al-PIA), and lanthanum-modified bentonite (LMB) in reducing phosphorus load in eutrophic water bodies. The changes of various forms of phosphorus in Al-PIA and sediment before and after the test were analyzed, and the mechanism of phosphorus migration and transformation in different capping systems was described. The dynamic simulation test lasted 95 days. The results showed that when the initial concentration of total phosphorus (TP) was 3.55 mg/L, the capping strength was 2 kg/m² and the hydraulic retention time of water circulation was 0.5 days, indicating that the average reduction rates of TP by LMB, Al-PIA and QS systems were 74.66%, 69.54%, and 3.64%, respectively, compared with the control system. The analysis of variance showed that there were significant differences (P < 0.05) in the TP concentration of the overlying water between the LMB, Al-PIA capping system, and the control system. Lanthanum ions in LMB can fix phosphorus. Al-PIA reduces the phosphorus concentration in water by means of ion exchange, adsorption, complexation, etc. LMB and Al-PIA promoted the migration of phosphorus in sediment. Among them, the phosphorus fixed by Al-PIA was mainly in the form of non-apatite inorganic phosphorus (NAIP) in inorganic phosphorus (IP), which can be seen; Al-PIA can effectively reduce the phosphorus load of eutrophic water.

    Abstract PURPOSE: Aluminum-based P-inactivation agent (Al-PIA) is a promising water treatment material, which has often been used for eutrophication restoration of water bodies. Numerous studies have shown that Al-PIA can control the release of phosphorus from sediment. However, whether the Al-PIA will destroy the bacterial community structure in sediment when it is used for capping of sediment and controlling the release of phosphorus from the sediment remains unknown. Therefore, this work aimed to study the effect of thin Al-PIA capping on bacterial communities in sediments. METHODS: This study used the surface sediment of a lake as the research object. The bacterial community structure of the sediments before and after the Al-PIA capping was analyzed by Illumina Genome Analyzer IIx. The community succession rule of the sediment bacterial in Al-PIA capping system was studied, and the influence of Al-PIA capping on the bacterial community structure in sediments was analyzed. RESULTS AND DISCUSSION: The test lasted for 45 days. The results showed that the Shannon index, Ace index, and Chao1 index of the capping system were larger than those of the control system. The diversity and abundance of the sediment bacterial community increased significantly. In the Al-PIA capping system, Proteobacteria, Bacteroides, Cyanobacteria, and Nitrospirillum were feature bacterial phyla. Meanwhile, Denitratisoma, Dechloromonas, and Cetobacterium were feature bacterial genus. CONCLUSION: Although Al-PIA capping had a certain impact on the bacterial community structure of sediment, it basically did not destroy the stability of the ecosystem and enhanced the self-purification ability of the water bodies. The results can provide theoretical guidance for the practical use of Al-PIA for sediment restoration.

    Abstract We determined the effects of quartz sand (QS), water treatment plant sludge (WTPS), aluminum-based P-inactivation agent (Al-PIA), and lanthanum-modified bentonite (LMB) thin-layer capping on controlling phosphorus and nitrogen release from the sediment, using a static simulation experiment. The sediment in the experiment was sampled from Yundang Lagoon (Xiamen, Fujian Province, China), which is a eutrophic waterbody. The total phosphorus (TP), ammonium nitrogen (NH ₄⁺ -N), and total organic carbon (TOC) levels in the overlying water were measured at regular intervals, and the changes of different P forms in WTPS, Al-PIA, and sediment of each system were analyzed before and after the test. The average TP reduction rates of LMB, Al-PIA, WTPS, and QS were 94.82, 92.14, 86.88, and 10.68%, respectively, when the release strength of sediment TP was 2.26–9.19 mg/(m²·d) and the capping strength of the materials was 2 kg/m². Thin-layer capping of LMB, WTPS, and Al-PIA could effectively control P release from the sediment (P < 0.05). However, thin-layer capping of LMB, Al-PIA, and QS did not significantly reduce the release of ammonium N and organic matter (P > 0.05). Based on our results, LMB, Al-PIA, and WTPS thin-layer capping promoted the migration and transformation of easily released P in sediment. The P adsorbed by WTPS and Al-PIA mainly occurred in the form of NAIP.

    Abstract PURPOSE: This work aimed to (i) investigate the effect of hydraulic retention time (HRT) on controlling the release of phosphorus from sediment and (ii) interpret the phosphorus migration and transformation mechanism in the Al-PHOSLOCK thin-layer capping system. METHODS: A 35-day laboratory dynamic simulation experiment was conducted by applying the Al-PHOSLOCK thin-layer capping to evaluate the effect of HRT on interrupting the release of phosphorus from contaminated sediments. The total phosphorus (TP), inorganic phosphorus (IP), organic phosphorus (OP), non-apatite inorganic phosphorus (NAIP), and apatite phosphorus (AP) were identified as different phosphorus species and analyzed during the experiment to further elucidate the migration and transformation of phosphorus. RESULTS AND DISCUSSION: The release of phosphorus from contaminated sediment was successfully suppressed by the Al-PHOSLOCK capping layer with an efficiency of higher than 90%. The HRT exerted a dual role on phosphorus controlling: at low HRT, slight water flow facilitated phosphorus migrating out from sediment and diffusing to the overlying water; at high HRT, the migration of phosphorus from overlying water back to sediment was strengthened. It was demonstrated that the phosphorus release was effectively controlled by the Al-PHOSLOCK thin-layer capping under different HRT conditions (static, 0.5 d, 1.0 d, and 3.0 d). The mechanism of phosphorus migration and transformation in the Al-PHOSLOCK thin-layer capping system was elucidated, including three significant stages of physical interception, adsorption, and capture/hold/transform process. CONCLUSION: This study verified the good capacity of the Al-PHOSLOCK capping system for controlling the release of sediment phosphorus under different HRT. Therefore, it was expected to be a promising approach in the handling of water eutrophication.

    Abstract It is well-known that the activated thin-layer capping covering by secondary capping of contaminated sediment poses a threat to the inactivation of activated material. In this study, the static simulation experiment was conducted to study the effect of secondary capping thickness by sediment on the control of TP release from the sediment by aluminum-based P-inactivation agent (Al-PIA), and to propose the phosphorus adsorption pathway of Al-PIA. The results showed that Al-PIA could effectively reduce the release of phosphorus pollutants from the sediment at the capping intensity of 2 kg/m
