Application Research Of New bio-filter in Tannery Wastewater Treatment Project Abstract: The test uses a new type of biological filter to study the biological treatment of tannery wastewater, mainly inspected on the water's CODcr and ammonia nitrogen removal. The results show that  tannery wastewater treated biologically by two tandem Biofilter, when the influent CODcr in the 300-500mg / L, ammonia nitrogen in the 100-300mg / L, the effluent CODcr less than 250mg / L, ammonia is less than 15mg / L, the effluent quality meets the emission standards for the tanning industry. the study also indicates that the process can be applied to the deep treatment of the tannery wastewater, providing an effective way for qualifying the tannery wastewater to meet the emission standards.
Key words: new biological filter technology; tannery wastewater; deep treatment

Application of a new type of aerated filter in advanced treatment process for Tannery Wastewater

Abstract: In this study, we introduce a new type of aerated filter and mainly investigate its removal effect for CODcr and ammonia nitrogen of infulent, using the Tannery Wastewater from bio-chemical treatment as the research object. The result showed that , using the the aerated filter with two-stage connection in series to dispose the Tannery Wastewater from bio-chemical treatment ,when the CODcr of infulent is at 300-500mg/L and the ammonia nitrogen is at 100-300mg/L, the CODcr of the Tannery Wastewater effulent is less than 250mg/L , the ammonia nitrogen is less than 15mg/L, the effluent water was conform to the pollutant emission standards for Tannery Industry. It also shows that this process can be applicated in the in advanced treatment of the Tannery Wastewater and offers an effective way for standard treatment of Tannery Wastewater.
Keywords: new type of aerated filter; Tannery Wastewater; advanced treatment
