“…The remediation effect of group Ve was due to the porosity and higher the external surface area. These characters of vesuvianite are beneficial to the absorption of contaminants (Li et al 2009;Jiang et al 2019). According to the good immobilization performance of oyster shells and walnut shells, and the large specific surface area of vesuvianite, probiotics immobilized by oyster shells, vesuvianite and walnut shells were applied to aquaculture water and sediment remediation in the follow-up experiment.…”

“…The results of SEM indicated that probiotics were not immobilized by vesuvianite, and group Ve showed lower relative concentrations of NH 4 -N, TN and COD Cr in sediment comparing with group C due to the absorption of vesuvianite. There was study showed that the addition of vesuvianite accelerated organic matter degradation and decreased cumulative CH 4 emissions due to their special porosity microstructures ( Jiang et al 2019). Modified vesuvianite exhibited a high adsorption capacity for phosphate (Li et al 2009).…”

“…The vesuvianite is another promising immobilization carrier. Vesuvianite shows a superior capability to remove pollutants, such as nitrogen, phosphate organic matter and CH 4 in the water and sewage sludge, which might be attributed to their high total pore volume, high specific area and low density (Li et al 2009;Jiang et al 2019;Kang et al 2019).…”

In the present study, we investigated the effect of probiotics immobilized by oyster shells (Os), vesuvianite (Ve) and walnut shells (Ws) on the remediation of aquaculture water and sediment by analyzing the variation of ammonia-nitrogen (NH4–N), nitrate-nitrogen (NO3–N), nitrite-nitrogen (NO2–N), total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (CODCr), as well as the microbiota of the water and sediment. The positive or negative effects of the treatment groups on the water quality parameters were both observed. Compared with their effects on water quality parameters, the treatment groups had better effects on sediment parameters. Group Ve had the best remediation effect of NH4–N and NO3–N in the sediment (decreased by 5.22 and 1.66 times, respectively). Group Os showed a lower relative concentration of TN and CODCr (decreased by 3.77 and 0.95 times, respectively). The high-throughput sequencing results revealed that the immobilized probiotics increased the relative abundances of functional bacteria in the treatment groups at the phylum and genus level. The above results showed that probiotics immobilized by oyster shells, vesuvianite and walnut shells positively affected the aquaculture environment's remediation, especially the sediment.

Landfill leachate usually contains a wide variety of organic pollutants, as well as high concentrations of salts, heavy metals, ammonia nitrogen, and total nitrogen. In different places, the leachate varies greatly due to the diversity of garbage components. The improper treatment of leachate would largely pollute the environment. Therefore, developing a suitable treatment method during leachate is still a big challenge [2].UASB reactor is an effective treatment method for waste incineration generated leachate. Recently, many studies have been focused on the UASB reactor based

“…Recently, software such as Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) and Functional Annotation of Prokaryotic Taxa (FAPROTAX) has been successfully used in predicting metagenome functional contents (Langille et al, 2013;Louca et al, 2016). In particular, PICRUSt is widely used and is appropriate for predicting function in various environmental samples, such as sewage treatment systems (Cui et al, 2019;Zhao et al, 2020), sewage sludge and manure composting processes (Jiang et al, 2019;Zhong et al, 2020), surface water and sediment samples (Wang et al, 2018;Su et al, 2018). Therefore, to understand the microbial community composition from suspended aggregates and semi-xed bio lm carrier, the change in community structure related to variable organic load, and their role in the N removal pathway, it is necessary to explore the functional pro le by means of PICRUSt.…”

The sequencing batch reactor (SBR) activated sludge process is a well-established technology for sewage treatment. One of the drawbacks of SBRs, however, is the failure to conform to the standard for total nitrogen (TN) discharge. By means of introducing four improvements, including semi-fixed biofilm carrier, sludge elevation mixing and change for the mode of influent and effluent, compliant standard for TN discharge was obtained in this novel SBR configuration during low- and high- -strength sewage load. To illustrate the microbial compositions and functions of the attached biofilm on semi-fixed carrier and the suspended aggregates, as well as the nitrogen removal pathway, high throughput 16S rRNA gene amplicon sequencing, PICRUSt2 algorithm and KEGG database were applied. The results revealed that: i) the microbial communities from suspended aggregates and biofilm samples were significantly different from each other; ii) during low-strength sewage loads, TN removal was mainly by nitrification-denitrification. The suspended aggregates was responsible for denitrification, while the biofilm was focused on ammonium oxidation; iii) during high-strength sewage loads, function of nitrate reductase from suspended aggregates was faded, and anammox and N assimilation by biofilm became dominant. Meanwhile, TN removal referring to the formation of L-glutamine via assimilation was the main pathway.
