Abstract:
... Adding alkaline into an anaerobic waste activated sludge (WAS) fermentation with thermophilic bacteria pretreatment could efficiently improve short-chain fatty acids (SCFAs) accumulation to 3550 ± 120 mg COD/L. The acidification rate in combined test was 21.2%, while that was 15.6% and 10.7% in sole thermophilic bacteria pretreatment and control tests respectively. Four distinct groups of microbes ...

Abstract:
... A hydrolysis acidification (HA)-anoxic–oxic (A/O) process was adopted to treat a petrochemical wastewater. The operation optimization was carried out firstly by a bench scale experimental reactor. Then a full scale petrochemical wastewater treatment plant (PCWWTP, 6500m³h⁻¹) was operated with the same parameters. The results showed that the BOD5/COD of the wastewater increased from 0.30 to 0.43 by ...

Abstract:
... Long‐term ecosystem development involves changes in plant community composition and diversity associated with pedogenesis and nutrient availability, but comparable changes in soil microbial communities remain poorly understood. In particular, it is unclear whether the diversity of plants and microbes respond to similar abiotic drivers, or become decoupled as resources change over long time‐scales. ...

Compared to the short-term experiment, we have a lack of understanding about the long-term effect of fertilizers on rice yield and paddy soil properties under the conditions of frequent soil disturbance and intensive cropping cultivation. Thus, a 32-year (1984–2015) field experiment was established on a red clay soil (typical Ultisols) near Nanchang, Jiangxi province, China, to assess the effects ...
