Reduction in greenhouse gas emissions from sewage sludge aerobic compost in China.
Sewage sludge is an important contributor to greenhouse gas (GHG) emissions and the carbon budget of organic solid waste treatment and disposal. In this case study, total GHG emissions from an auto-control sludge compost system, including direct and indirect emissions and replaceable reduction due to sludge compost being reused as fertilizer, were quantified. The results indicated that no metha...
متن کاملMicrobacterium luticocti sp. nov., isolated from sewage sludge compost.
Strain SC-087B(T), isolated from sewage sludge compost during a study of bacterial diversity in composts, was characterized. The isolate was a Gram-positive, short rod that was motile, catalase- and oxidase-negative and able to grow at 27-45 degrees C, pH 5.5-9.7 and in up to 10 % NaCl. The peptidoglycan was of the B2beta type, containing the characteristic amino acids ornithine, homoserine and...
متن کاملThe one-stage autothermal thermophilic aerobic digestion for sewage sludge treatment: stabilization process and mechanism.
Batch experiment was carried out in a simulated thermophilic aerobic digester to investigate the digestion process of one-stage autothermal thermophilic aerobic digester and to explore the sludge stabilization mechanism. Volatile solids removal was 38.4% at 408 h and 45.0% at 552 h. Chemical oxidation demand, total nitrogen, and ammonia nitrogen in supernatant increased rapidly up to 168 h, and...
متن کاملIsolation, identification and utilization of thermophilic strains in aerobic digestion of sewage sludge.
Two representative thermophilic bacterial strains (T1 and T2) were isolated from a one-stage autothermal thermophilic aerobic digestion pilot-scale reactor. 16S rRNA gene analysis indicated that they were Hydrogenophilaceae and Xanthomonodaceae. These isolated strains were inoculated separately and/or jointly in sewage sludge, to investigate their effects on sludge stabilization under thermophi...
متن کاملChemical and microbial changes during autothermal thermophilic aerobic digestion (ATAD) of sewage sludge.
Autothermal thermophilic aerobic digestion (ATAD) is a promising process for sewage sludge stabilization. Batch experiments were conducted on sewage sludge collected from a municipal wastewater treatment plant in Shanghai, China, to evaluate the effectiveness of the ATAD system by determining changes in volatile suspended solids (VSSs) and to study its microbial diversity by denaturing gradient...
