The Moving Bed Biofilm Reactor of Magnetic photocatalysis on Mariculture wastewater

Abstract

In view of the high dissolved organic matter and salt content of the Mariculture wastewater in coastal industrial clusters, because that moving bed biofilm reactor (MBBR) normally faces the unbalanced carbon -nitrogen ratio and long flow, MBBR is rarely used for wastewater treatment of mariculture wastewater. Moving bed biofilm reactors of magnetic photocatalysis (MPBR) were treated with mariculture wastewater and constantly purified wastewater on a seawater ranch in Hebei. Results show that this biofilm colonization is completed faster than the other MBBR or magnetic photocatalysis microsphere. That typical constituents in this biofilm were confirmed by fourier transform infrared spectroscopy (FTIR). Pyrosequencing of 16srRNA revealed that SphaeroCalus was the predominating microbial community in MPBR. Therefore, the MPBR will be a promising alternative for the mariculture wastewater. These processing techniques can effectively reduce the risk of impact load on seawater ranch in Northern coastal areas.
