Trimethylolpropane (TMP) wastewater is one of the most toxic petrochemical wastewater. Toxicants with high concentrations in TMP wastewater often inhibit the activity of microorganisms associated with biological treatment processes. The hydrolysis acidification process (HAP) is widely used to pretreat petrochemical wastewater. However, the effects of HAP on the reduction of wastewater toxicity and the relevant underlying mechanisms have rarely been reported. In this study, an HAP reactor was…

TLDR
The genus Hydrogenophaga was related to organic removal performance, while Zoogloea and Chitinophaga were related to the effluent quality of suspended solids, and Loosely bound extracellular polymeric substances (EPS) showed more significant effect on sludge settleability than the tightly bound EPS.

TLDR
In this study, the decomposition of simulated anthraquinone reactive dye at a concentration of 400-mg/L in wastewater by a biofilm hydrolytic-aerobic recycling system was investigated over a range of recycling fluxes and revealed that the recycling flux was a key factor that influenced RB19 degradation.
