چکیده
In order to improve the removal efficiencies of SS and Fe3+ in anaerobic digestion reject water for subsequent biological treatment process, on basis single factor test early stage, response surface method was used, structure formed floc analyzed by magnetic flocculation. The optimum amounts powder, polyaluminum chloride (PAC) polyacrylamide (PAM) were 40.51 mg/L, 31.31 mg/L 4.05 respectively. At this time, 97.84% 98.35%. effects particle size, scanning electron microscopy, infrared spectroscopy two-dimensional fractal dimension flocs flocculation ability showed that: compared with conventional coagulation, average size treated 76.56 μm, Fe-O-Al absorption peak appeared at 984 cm−1, significantly improved, rough porous, dense, sedimentation performance improved also.

Anammox: a Sustainable Process to Remove Nitrogen from Reject Water Generated by Anaerobic Digestion Processes
EXTENDED ABSTRACT The City College of New York (CCNY) in collaboration with New York City Environmental Protection (NYCEP) is currently engaged in operating a 1700 gallon pilot single stage partial nitritation/anaerobic ammonium oxidation (anammox) moving bed biofilm reactor (MBBR) at the 26th Ward waste water treatment plant (WWTP) in Brooklyn, NY. The MBBR is designed to remove nitrogen from ...
متن کاملAnaerobic Digestion Technology for Industrial Wastewater Treatment
Anaerobic digestion is the most suitable option for the treatment of high strength organic effluents. The presence of biodegradable components in the effluents coupled with the advantages of anaerobic process over other treatment methods makes it an attractive option. This paper reviews the suitability and the status of development of anaerobic reactors for the digestion of selected organic eff...
