Sep 27, 2022 · The silt in the Yellow River alluvial plain typically features low strength and poor water stability, and, thus, alluvial silt treatment needs an amount of cement to improve soil performance. The development of an alternative to reduce or replace the use of cement in soil stabilization has been a hot topic research for a long time. This paper develops an industrial-solid-waste (ISW) curing
Jun 11, 2021 · Although composting is effective in deactivating antibiotic substances in manure, the influence of compost fertilization on the occurrence and dissemination of antibiotic resistance in arable soils remains to be controversial. Herein, the abundance and diversity of two sulfonamide resistance genes (sul1 and sul2) in soil fertilized by compost spiked with two concentrations of sulfadiazine (1
Jan 14, 2022 · Composting is an important technology used to treat and convert organic waste into value-added products. Recently, several studies have been done to investigate the effects of microbial supplementation on the composting of agro-industrial waste. According to these studies, microbial inoculation is considered to be one of the suitable for enhancing the biotransformation of organic

Nov 20, 2022 · A composite dust suppressant for Yellow River alluvial silt was developed. • Response surface method was used to get the formulation of the dust suppressant. • The dust suppressant had excellent mechanical properties and weather resistance. • The dust suppression efficiency of the dust suppressant was high and long-term. •
Silt is formed by the erosion of rocks and soils, organic activities, and local discharges caused by human and industrial activities. 15 According to the statistics of dredging sludge operation, it can reach 250 Mm 3 every year in Europe alone, 16 of which 50 Mm 3 occurs in France. 17 Silt refers to soft soil with a large average natural
Nov 23, 2023 · Purpose Co-composting with agriculture waste and sediment is an effective method to passivate the heavy metal content of sediment, but it is still unclear whether this passivation will be effective in the long term, and the contribution of different components of humic substances (HS) to the passivation of heavy metals has not been investigated quantitatively. A 256-day composting
Nov 1, 2020 · This means that the corrosion resistance of EP resin in a sulfuric acid solution can be effectively improved by adding g-C 3 N 4 nanosheets, and the optimal corrosion resistance was obtained at 2 wt% addition level.

Jul 24, 2023 · Collective mechanism of corrosion and erosion results in severe surface deterioration with heavy material loss due to synergistic effect. Erosion-corrosion is mainly observed in the pipelines used in oil and gas industries, petroleum industries, heat exchanges and mainly in marine equipment.
Jul 24, 2023 · corrosion and sand present in sea water acerates erosion corrosion. Moveable components present in marine equipment unavoidably suffer from corrosion and wear. The impact of erosion-corrosion in industrial sectors is depicted in Figure 1. Even though the fundamental phenomenon of slurry erosion is known very well, the intricacies involved further
Aug 11, 2020 · Corrosion is the scourge in our metal-based civilization. Corrosion-induced material degradation annually accounts for at least 2–3% of gross national product for an industrialized economy 1.
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
