We first revealed the behavior and biochemical mechanism of high iron attapulgite (HIAP) different dosages affecting sewage sludge (SS) composting. HS/TOC ratio increased, but HA/TOC HA/FA ratios reduced with increase in HIAP dose. High-dose promoted formation more HS by weak catalytic effect could bind FA than HA strong adsorption to inhibit polymerization adsorbed into HA. Mixing SS subsequent composting as two consecutive processes during HIAP-amended significantly influenced species distribution heavy metals (HMs) Cu, Zn, Cr. Each process roughly contributed one-half HMs passivation. The bioavailable fraction (BF) dose greatly affected microbial community. Both 1% 5% treatments Proteobacteria Firmicutes, 10% Actinobacteriota Bacteroidota. At thermophilic phase, core genera, which were correlated pile temperature pH value. In maturity stage, genera basically similar closely HA, influence order was BF–Cr > BF–Cu BF–Zn optimal recommended.

The improper treatment of crop straw not only leads to resource wastage but also adversely impacts the ecological environment. However, application microorganisms can accelerate decomposition and improve its utilization. In this study, cellulose-degrading microbial strains were isolated from naturally decayed corn screened using Congo red staining, along with assessing variations in carboxymethyl cellulase (CMCase) activity, filter paper enzyme (FPase) activity β-glucosidase (β-Gase) as well degradation rate. eight strains, namely Neurospora intermedia isolate 29 (A1), Streptomyces FFJC33 (A2), Gibberella moniliformis FKCB-009 (A3), Fusarium fujikuroi EFS3(2) (A4), Fujikuroi FZ04 (A5), Lysine bacillus macroides strain LNHL43 (B1), Bacillus subtilis MPF30 (B2) Paenibacilli lautus ALEB-P1 (C), identified selected for consortium design based on their high activities CMCase, FPase β-Gase. fungi, bacteria actinomycete combined without antagonistic effects decomposition. results showed A2B2 combination had a significantly higher at 55.44 U/mL β-Gase 25.73 than other two combinations (p < 0.05). Additionally, rate was 40.33%, which considerably that strains/consortia. A4B2C superior including CMCase value 35.03 U/mL, 63.59 26.15 different those three Furthermore, seven single construct various consortiums situ composting order evaluate potential. Taken whole, composting, temperature, moisture content, pH, E4/E6 seed germination index, indicated consisting intermediate 29, EFS3(2), FZ04, Lysinibacillus macrolides, sphaericus, Paenibacillus advantageous yielded high-quality compost. flora able effectively degrade straw. This study provides novel solution construction

Aerobic composting of conventional municipal sludge has always had the problems nitrogen loss and low humification. In this study, biolysed (BS), polyacrylamids-added (PS) Fe (III)/CaO-added (FS) were used for composting, respectively, their effect on physical-chemical parameters, conversion humification during investigated. The results showed that dissolved organic matter (DOM) concentration BS pile (23.1 ± 0.4 g/kg) was 48.4% higher than PS (15.5 FS piles 0.0 in initial stage became lowest after suggesting degradation DOM promoted pile. can also increase retention rate total (TN) (27.8% 0.8%), (22.7% 1.1%) (24.6% 0.5%), which may be due to lower production ammonia Compared with FS, provided more humic substance (HS) acid (HA) HA contents compost products 34.4 1.0, 35.4 0.2 34.0 0.3 mg/g PS, treated piles, respectively. Fourier transform infrared excitation-emission matrix revealed aromaticity stability HA. degree polymerization (DP) from (1.48) (1.56) (1.36). However, germination index (GI) value (133.4% 6.0%) (152.3% 6.2%) (158.3% showing contain plant biotoxicity. Thus, compared maturity compost.
