In light of the ongoing socio-economic development, considerable attention has been directed towards wastewater due to its detrimental impact on water quality and associated health risks. The efficiency of removing organic pollutants from municipal sewage in a modified waste cotton cloth biofilm reactor (MWCCBR) is heavily influenced by operational functions and micro-environmental conditions. This study aimed to identify the most favorable combination of conditions that would maximize organic pollutant removal efficiency in the biofilm reactor. To achieve this research goals, an orthogonal test was conducted to investigate the optimal operation parameters, including carrier filling rate, hydraulic retention time, oxygen demand, and temperature, in order to enhance the removal of contaminants. Through a series of orthogonal experiments involving various factor levels, the most effective removal efficiencies were achieved under the following conditions: hydraulic retention time (HRT) of 10 hours, dissolved oxygen (DO) level of 3.0 mg/L, temperature of 35°C, and a filling rate (FR) of 65.0%. Throughout the treatment period, while maintaining the stable operation of the biofilm reactor, effluent samples were collected to assess the concentrations of chemical oxygen demand (COD), ammonia-nitrogen (NH4+-N), and total phosphorus (TP), along with their corresponding removal efficiencies. During the stable and optimal operational phase of the modified waste cotton cloth biofilm reactor, the average removal efficiencies for COD, NH4+-N, and TP were found to be 96.5±0.3%, 82.8±6.6%, and 60.1±0.5%, respectively. The outcomes of this study have significant implications for alternative approaches to solid waste reduction, optimal bioreactor operation, the production of value-added recycled products, the provision of clean water, and the promotion of a sustainable environment. © 2024, The Authors.

Nitrogen (N) fertilizer is highly significant in agricultural production. chemical nitrogen fertilizer is of great significance to agricultural production. However, long-term N addition causes changes in quality indicators, such as soil organic matter (SOM), thus, affecting the absorption and accumulation of organic pollutants. Therefore, paying more attention to organic fertilizers in the development of green agriculture is necessary. However, the accumulation of heavy metals (HMs) contained in organic fertilizers (especially sewage sludge compost (SSC)) in the soil can cause environmental contamination, but how this cumulative reaction changes with the long-term N addition remains unclear. Here the SSC impact on the bioavailability of five typical HMs (Cd, Cr, Cu, Pb, and As) in the soil-plant system without and after SSC application was demonstrated through a field study in soils with different application rates of 0, 100 and 300 kg N ha −1 yr −1 , respectively. Our results showed that SSC application increased the concentration of most HMs in soil profiles and plant systems (wheat roots and grains), but the accumulation rate of HMs and most bioaccumulation values (BAC-bioaccumulation coefficient and BCF-bioconcentration factor) in plant systems were both lower in high-N addition soil than that in the low-N group. Moreover, speciation distribution results further indicated that SSC application increased the LB (liable available form, including F1-water soluble, F2-ion exchangeable, and F3-bound to carbonates) form of HMs and decreased the PB (potentially available form, including F4-humic acids and F6-fraction bound to organic matter) form of HMs in high-N addition soil, respectively. Those results suggested that HM bioavailability was larger in high-N addition soil than in low-N addition soil when applied with SSC. Overall, this study found that increasing soil N content can inhibit the bioavailability of HMs when applying SSC, providing suggestions for optimizi

The mobilization and enrichment of arsenic(As) in groundwater is considered to be mainly affected by microbial dissimilation reduction, however competitive adsorption and complexation of natural organic matter(OM) complicate its mobilization in field scene. High concentration of biodegradable OM and high-As aquifer sediment were cultivated in batch experiment to focus on the microbial affected As release patterns and its controlling process. The small molecular OM(glucose and sodium lactate) with no potential competitive adsorption and complexation effects on As mobilization were used. We have shown that active OMs can rapidly stimulate indigenous microorganisms. As a driving factor of redox reaction, OM could remove As from sediments through microbial mediated reduction and dissolution of Fe oxide, and HA can promote this process. OMs can increase the relative abundance and activity of anaerobic/facultative anaerobic metal dissimilation reducing bacteria, including Proteobacteria, Firmicutes, Actinobacteria and Bacteroides. The change of microbial community is a comprehensive reaction of mobilization of As, Fe, Mn, OM degradation, redox conditions and pH changes. The results support that microorganisms participate in the process of As mobilization by using active OMs. This study shows the potential risk of surfaced derived OM could degrade groundwater quality by stimulating groundwater As, Fe and Mn release. © 2022, The Authors.

The relationship between biomass components and carbon retention or loss in biochars is unclear. In this study, four characteristic feedstocks were converted into biochars, and their thermal degradation behavior during pyrolysis were different. The biochars derived from lignin-rich biomass had higher aromaticity and carbon retention, indicating that lignin was a major contributor to the formation of biochar (40.1-53.2%). The K 2 Cr 2 O 7 oxidation experiment depicted that the carbon stability of sunflower and cotton stalk char was relatively poor. Because the unstable carbon produced by lignin–poor biomass pyrolysis was more susceptible to loss or conversion. These findings are extremely meaningful for guiding in biochars preparation and avoiding their environmental risks. © 2021, The Authors. All rights reserved.

2,2’-DiBBPA is frequentlydetected in the environment. However, mobility of 2,2’-diBBPA in the soil environment is poorly examined. The present study examined the effects of soil components, dissolved organic carbon and heavy metal cations on adsorption of 2,2’-diBBPA on several types of agricultural soils. The adsorption isotherms on soils and soil components were well fitted to the linear isotherm equation. Under neutral conditions, soils with higher soil organic matter (SOM) exhibited greater adsorption capacity for 2,2’-diBBPA, indicating the significant contribution of SOM to the adsorption. The adsorption capacity of a given soil for 2,2’-diBBPA decreased with increasing pH due to the enhanced electrostatic repulsion between the anionic 2,2’-diBBPA and soils. Black carbon of soil organic carbon played a predominant role in the adsorption of 2,2’-diBBPA on soils. Metal ions significantly inhibited the adsorptive behavior of 2,2’-diBBPA under alkaline conditions. Dissolved organic carbon, iron oxide minerals, and phyllosilicate minerals exhibited a limited effect on 2,2’-diBBPA sorption. Biota-sediment accumulation factors (1.18-2.47) and logarithm of bioconcentration factors (2.49-2.52) of 2,2’-diBBPA in lugworms decreased and increased with increasing Kd, respectively. These findings indicate that mobility in soils and bioaccumulation of 2,2’-diBBPA is associated with soil SOM, pH, and heavy metals. © 2022, The Authors. All rights reserved.

Nonylphenol (NP) has been widely concerned for its endocrine disrupting effects and bioconcentration in aquatic organisms. However, the knowledge on the dynamic uptake and depuration in model organisms - zebrafish (Danio rerio) were still limited. In this study, we investigated the accumulation and elimination of NP for the whole body and trunk of zebrafish by a modified pretreatment and analysis method with fewer samples. The results of acute toxicity test showed that the LC50 values of NP in zebrafish ranged from 474 μg·L-1 for a 24-h exposure to lower than 238 μg·L-1 for a 96-h exposure. Meanwhile, the NP concentrations in zebrafish during the depuration stage fitted the first-order kinetic model well, and the depuration rate constant (K2) was reduced with higher NP concentrations. Both the accumulation and elimination of NP in the trunk were faster than those in the whole fish, indicating the preferential transfer from viscera to muscle and rapidly diffusion in reverse. The bioconcentration factors at a steady state (BCFSS) of NP were 104 - 112 L·kg-1 in the whole body and 76 - 104 L·kg-1 in the trunk, respectively, suggesting that the muscle was a major position for NP storage. The BCFSS were increased within a certain concentration due to the decreasing depuration capacity inhibited by NP toxicity. To our knowledge, this study was the first to emphasize the correlation between NP exposure concentration and bioconcentration capacity. © 2021, CC BY.

Methanol-to-olefin (MTO) is a typical example of the new coal chemical industry. Due to the large volume of generated wastewater, complex composition, and heavy environmental hazard, wastewater recycling is critical for sustainable industrial development and ecological protection. Herein, a swirl regenerating micro-channel separation (SRMS) technology integrating deep filtration and hydrocyclone-enhanced regeneration was proposed. A small-scale experimental investigation was first conducted to verify the feasibility of the MTO wastewater treatment. A pilot SRMS device with a treatment capacity of 20 m3/h was constructed, and the continuous operation effect and stability of the device were comprehensively evaluated. The separation performance of the SRMS device at different solution pH values and the effect of the hydrocyclone-enhanced regeneration of separation media were discussed in detail.
