A lanthanum modified sludge biochar chitosan (La-SBC-CS) microsphere was successfully synthesized by dropping (BC) and into a chloride solution. Batch adsorption experiments were conducted to investigate the kinetics isotherm. Application of continuous phosphate removal achieved via lab-scale column reactors. The equilibrium data La-SBC-CS fitted well with Freundlich isotherm, maximum amount 81.54 mg p/g at 25 °C. Characterization adsorbent using scanning electron microscopy analysis (SEM),...
In this study, a laboratory-scale sequencing biofilm batch reactor (SBBR) was employed to explore fast start-up of completely autotrophic nitrogen removal over nitrite (CANON) process. Partial nitrification achieved by controlling free ammonia concentration and operating at above 30 °C; then the immediately operated with alternating periods aerobiosis anaerobiosis start anammox The CANON process successfully in less than 50 d, total-nitrogen efficiency rate were 81% 0.14 kg-N m−3 d−1...
Although anaerobic ammonia oxidation (anammox) is considered a promising process due to its high efficiency and low energy in nitrogen removal, nitrite inadequacy was one of the bottlenecks for application anammox. However, endogenous partial denitrification (EPD) has been emerging as stable pathway provide Furthermore, denitrifying glycogen-accumulating organisms (DGAOs) are believed be associated with EPD. In this study, firstly, GAOs were gradually enriched sequencing batch reactor (SBR)...
A sequencing batch biofilm reactor (SBBR) was operated at different salinities with focus on performance and nitrogen removal by simultaneous nitrification denitrification (SND). The SBBR contained suspended-growth sludge attached to synthetic fibrous carriers. When salinity increased from 1.4 4.2 g NaCl/L, it the -N total efficiencies, rate (NR), (DNR). slight drop in removal, NR, DNR observed, when 9.8 NaCl/L. Efficient SND occurred efficiency above 90.7%. Nitrification main contribution...
The start-up and performance of the completely autotrophic nitrogen removal via nitrite (CANON) process were examined in a sequencing batch reactor (SBR) with intermittent aeration. Initially, partial nitrification was established, then DO concentration lowered further, surplus water SBR high replaced tap water, continuous aeration mode turned into mode, while total still weak. However, (TN) efficiency loading reached 83.07% 0.422 kgN/(m 3 ·d), respectively, 14 days after inoculating 0.15 g...
Abstract In this study, the effects of elevated chemical oxygen demand/nitrogen (COD/N) ratios on nitrogen removal, production and composition extracellular polymer substances (EPS) microbial community a completely autotrophic removal via nitrite (CANON) process were studied in sequencing batch membrane bioreactor (SBMBR). The whole experiment was divided into two stages: CANON stage (without organic matter influent) simultaneous partial nitrification, anaerobic ammonia oxidation...
Adding biochar can expedite the establishment of anaerobic ammonia oxidation (anammox) process and improve nitrogen removal efficiency anammox reactor. However, optimization research derived from dewatered sludge on is relatively limited. In this study, four sequencing batch reactors (SBRs) were compared for enrichment bacteria using synthetic wastewater with carbonized at temperatures 300°C, 550°C, 800°C, without (CK). The start-up performance evaluated, as well effect organic carbon...
Biological phosphorus removal was studied in a sequencing batch reactor (SBR). The results showed that nitrite could be used as electron acceptor denitrifying removal. Feed mode of had significant influence on Anoxic assimilation rate reach 10.44 mgP/gSS.h and the percentage anoxic amount more than 97% with continuous feed mode. Granular sludge activity found SBR. effects different operational conditions, such COD loading, settling time, HRT etc., formation granules were also studied.
The enrichment of denitrifying phosphate accumulating organisms (DNPAOs) is the prerequisite for removal process.This study investigated effect nitrate concentration on DNPAOs was studied with batch experiments.The Sequencing Batch Reactor (SBR) set-up acetate as sole carbon source.The addition solution and anoxic time were gradually increased time.Denitrifying phosphorus accumulation observed soon, but concentrations nitrite in effluent fluctuated at beginning.Then adjusting according to...
