新型生物濾池在制革廢水深度處理工程中的應用研究 摘要:試驗采用一種新型的生物濾池,以生化處理后的制革廢水為研究對象,重點考察了裝置對進水的CODcr和氨氮的去除效果。結果表明,采用兩級串聯(lián)生物濾池處理生化處理后的制革廢水,當進水CODcr在300-500mg/L、氨氮在100-300mg/L時,出水CODcr小于250mg/L、氨氮小于15mg/L,出水水質能夠達到制革行業(yè)污染物排放標準;同時說明該工藝能夠應用于制革廢水的深度處理,也為制革廢水的達標處理提供了一條有效的途徑。 關鍵詞:新型生物濾池工藝;制革廢水;深度處理 [ Last edited by 811708515 on 2011-2-28 at 16:49 ] |

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 |
