Abstract

Ultrasonic assisted method was used to synthesize magnetic layered double hydroxide (LDH) with super-paramagnetic ferrite and eggshell-based LDH, then magnetic LDH/PU composite material was synthesized with magnetic LDH and polyurethane (PU) by one-step foaming method. The external carbon source of biological denitrification process was obtained by the magnetic LDH/PU composite material which adsorped by short-chain fatty acids (SCFAs). Results of X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) indicated that magnetic LDH had a typical layer structure of hydrotalcite, and magnetic LDH/PU composite materials not only had the characteristic of large porous surface area of PU, but also evenly dispersed the LDH throughout the entire system. The result showed that the maximum extraction efficiency of short-chain fatty acids from sludge reached 79.3%, and magnetic LDH/PU-SCFAs with sustained release performance could increase carbon source utilization by 6.7% in denitrification over using glucose. This research indicated that the magnetic LDH/PU-SCFAs can be used as a new type of high-efficiency biodenitrification carbon source.
