美國國家層面大力推進側流污水生物除磷(S2EBPR)技術的開發與應用! 

美國從國家層面大力推進活性污泥側流發酵技術的應用,著名的Black & Veatch, CDM-Smith, Hazen & Sawyer, Brown and Caldwell等公司和一些大學,聯合開展活性污泥側流發酵技術(S2EBPR)的開發與應用。并將S2EBR作為2010年后污水生物脫氮除磷技術發展史上的標志性技術。

As phosphorus limits permitted in wastewater effluent shrink to protect drinking water sources, a nationwide research effort headed by Black & Veatch has started work toadvance implementation of a leading-edge treatment technology for phosphorus removal and recovery.

Pioneered by Black & Veatch’s Dr. James Barnard in the 1970s and offering greater efficiency and cost-effectiveness than chemical processes, enhanced biological phosphorus removal (EBPR) has been adopted by communities worldwide to meet water quality requirements.Yet understanding of the process’s ecology, functionality and optimal design remains incomplete. Selected by the Water Research Foundation (WRF),the Black & Veatch-led team will be completing research to establish a standard approach to EBPR’s application.

With a value of $1.3 million plus approximately $1.2 million from in-kind and cost-share contributions, the WRF research project is focused specifically on the application of an EBPR configuration called Side Stream Enhanced Biological Phosphorus Removal, or S2EBPR. The configuration uses anaerobic conditioning of activated sludge biomass to promote stability and consistent performance in the biological nutrient removal (BNR) process. The objectives of this project are to develop design guidelines, operational tool recommendations, and modeling best practices for S2EBPR facilities.

WRF研究項目的價值為130萬美元,外加大約120萬美元的實物和成本份額捐款,該項目的重點是側流EBPR工程化應用,稱為側流強化生物除磷,即s2ebpr。該工藝是利用活性污泥深度厭氧發酵過程來提高生物脫氮除磷(BNR)過程中的穩定性和可靠性。該研究項目的目標是為s2ebpr設施制定設計指南、操作工具建議和建模最佳實踐。

Leon Downing, Principal Process Engineer and Innovation Leader at Black & Veatch, is the project’s principal investigator. Downing is joined by co-principal investigator professor April Gu of Cornell University and Dr. Barnard, who is credited with formalizing many BNR processes and who is leading the project’s advisory team. A blue-ribbon team has been assembled to complete the research over the next 30 months. The team includes five consulting firms: Black & Veatch, CDM-Smith, Hazen & Sawyer, Brown and Caldwell, and Gert P Environmental ApS.Five universities are participating including Cornell, Washington, Northwestern, Northeastern, and Aarhus. Utility partners include:

  • Metropolitan Water Reclamation District of Greater Chicago, Ill.
  • Metro Wastewater Reclamation District, Denver, Colo.
  • Charlotte Water, NC
  • Hampton Roads Sanitation District, VA
  • Clean Water Services, OR
  • Geneva, Ill.
  • Western Wake WRD, NC
  • Boulder, Colo.
  • NEW Water, Green Bay, Wisc.
  • Wilson, NC
  • Trinity River Authority of Texas
  • Madison Metropolitan Sewerage District, Wisc.
  • Longmont, Colo.
  • DC Water, Va.
  • Toronto Water, Canada
  • Olathe, KS
  • South Cary, NC

“Our industry is ready for a universally recognized and user-friendly approach to EBPR,” Downing said. “By promoting improved performance and process stability in EBPR, this research will greatly help utilities minimize their chemical and energy costs as well as achieve very low concentrations of phosphorus in their effluent.”

"通過側流生物除磷技術,提高EBPR的性能和工藝穩定性,這項研究將極大地降低污水廠化學和能源成本,并使廢水中的磷濃度達到極低的水平。"

Phosphorus is essential to plant and animal growth. Yet the nutrient becomes a pollutant when deposited in waterways in excessive amounts via wastewater discharges and stormwater runoffs, fueling toxic algal blooms and contributing to hypoxic dead zones that threaten ecosystems and public health. Effective removal of phosphorus during wastewater treatment is gaining more and more scrutiny from communities and regulators. EBPR is also the precursor to enabling many of the technologies currently utilized for phosphorus, as well as carbon/energy recovery from wastewater.
