The Application of Biofortification in Natural Rubber Processing Wastewater Treatment

Abstract

According to the water quality of natural rubber processing wastewater and related sewage discharge standards, a combination process of anaerobic and two-stage biological contact oxidation (A/O 1 /O 2 biofilm) was used to treat natural rubber processing wastewater. Biofortification was considered as the core technology in this case that Bacterial agents were directly added and biological fillers were adopted to fix the microorganisms, and therefore strengthen the operation of the biological treatment system. After the commissioning of this process, it was officially put into operation, and related sewage discharge indicators (including pH, SS, NH3-N, COD and BOD5 ) had shown to meet all the first-level standard of "Integrated wastewater Discharge Standard"(GB8978-2002).
