Excess biological sludge processing and disposal have a significant impact on the energy balance economics of wastewater treatment operations, receiving environments. Anaerobic digestion is probably most widespread in-plant method globally, since it stabilizes converts biosolids organic matter into biogas, allowing partial recovery their embedded chemical energy. A considerable number studies concerning applicable techniques to improve biogas production, both in quantity quality, include pre-treatment strategies promote disintegration aimed at release solubilisation intracellular compounds, inorganic/biological amendments improving process performance, thermal pre-treatment. As for in-process amendments, iron, micro macro-nutrients, ashes from waste incineration nanoparticles addition been studied improvement enzymatic reactions. Recently, use electrically conductive materials has credited with possibility accelerate stabilize conversion substrates methane. The increasing generation its relative biomethane content by interfacing anaerobic bioelectrochemical systems was also postulated. This review addresses research gap surrounding integration novel technologies, particularly systems, enhance production methane enrichment. While existing focus feasibility, mechanisms, benefits such remain underexplored. By critically evaluating current state art, this identifies potential stability, while highlighting key challenges needs advancing these technologies toward practical implementation.

As an adsorbent, biochar has a highly porous structure and strong adsorption capacity, can effectively purify the environment. In response to increasingly serious problem of heavy metal pollution in water, this study used nano zero valent iron rice husk prepare new type magnetic sheet-like loaded (BC-nZVI) composite material through rheological phase reaction, showing remarkable advantages such as low cost, easy preparation, superior environmental remediation effect. The physical chemical properties were extensively characterized using various methods HRTEM, XPS, FESEM, EDS, XRD, FTIR, RAMAN. Concurrently, batch experiments undertaken assess removal efficiency Pb(ii) by BC-nZVI, with investigations into influence pH value, temperature, soil water ratio, initial concentration ion solution on its efficiency. results indicate that BC-nZVI reaches equilibrium state after around 120 minutes. Under conditions 6, temperature 20 °C, ratio 1 : 5, dosage g L-1, reduce content wastewater 30 mg L-1 trace levels, treatment time is about analysis kinetics isotherms indicates process adheres quasi-second-order kinetic model Langmuir model, suggesting process. Thermodynamic findings reveal spontaneous. Furthermore, primarily accumulates co-precipitation. serves eco-friendly, cost-effective, efficient promising capabilities mitigating pollution. Its recoverability reusability facilitated external field make it advantageous for remediating treating lead-contaminated sites.

Anaerobic co-digestion is an effective method for addressing the issue of a single substrate not being able to achieve optimal conditions anaerobic digestion. By adjusting mixture ratio sewage sludge and food waste carbon nitrogen ratio, effectiveness thermophilic-mesophilic temperature phase (TPAcD) was evaluated in comparison mesophilic (MAcD) thermophilic (TAcD). The results indicated that TPAcD increased methane yield by 50.3% 32.7% compared MAcD TAcD, respectively. variation VFA, pH, ammonia levels demonstrated combines advantages both with higher hydrolysis rate early stage under (55 °C) suitable environment later (35 °C). kinetic parameters co-digestions also performs better. Therefore, further research on warranted due its significant improvements production rate, total yield, system stability. Additionally, contributes reducing emissions supports realization "carbon neutrality".

Anaerobic digestion is an important technology for energy recovery from organic waste. However, methanogenesis restricted by some barriers, such as the low-speed bottleneck of interspecies electron transfer (IET), low hydrogen partial pressure limitation, trace element deficiency, etc., resulting in poor system stability and methane production. Recently, multiple iron accelerants have been employed to overcome above challenges proven effective enhancing methanogenesis. This study reviews effects (Fe0, Fe3O4 magnetite, Fe2O3 hematite, salts other accelerants) on anaerobic terms production, process microbial community elaborates mechanisms mediating direct (DIET) syntrophic methanogenic community, strong reducibility promoting methanogenesis, provision nutrient elements microorganisms, etc. The potential engineering application current research advances regarding environmental impacts are also summarized. Although exhibit positive digestion, most focuses laboratory small-scale investigations, its large-scale should be further verified. Future focus elucidating developing diverse methods different types systems, optimizing applications, exploring high-efficiency strategies accelerants.

Conductive materials (CM) enhance methanogenesis, but there is no clear correlation between conductivity and faster methane production (MP) rates. We investigated if MP by pure cultures of methanogens (Methanobacterium formicicum, Methanospirillum hungatei, Methanothrix harundinacea Methanosarcina barkeri) affected CM (activated carbon (AC), magnetite), other sustainable alternatives (sand glass beads, without conductivity, zeolites (Zeo)). The significant impact the was on M. formicicum as significantly accelerated non-CM (e.g., sand reduced lag phase (LP) duration 48 %), Zeo AC (LP reduction in 71% 75 %, respectively). Conductivity not correlated with LP reduction. Instead, silicon content inversely time required for complete MP, per se stimulated formicicum's activity. These findings highlight potential using silicon-containing anaerobic digesters to accelerate methanogenesis.
