  • Patent number: 7435349
    Abstract: A system for treating wastewater containing organic compounds is provided, comprising an anaerobic bioreactor, an aerobic bioreactor disposed rearwardly of the anaerobic bioreactor, and a membrane separation reactor disposed rearwardly of the aerobic bioreactor. The system is capable of removing organic pollutants in wastewater through biological treatment process and separating solid from the liquid ones by using a membrane. By employing the system for treating wastewater containing organic pollutants, organic pollutants can be effectively eliminated and the problem of scaling and fouling on the surface of the membrane prevented, thus achieving the objectives of lowering cost and improving efficiency.

  • Patent number: 7407580
    Abstract: The present invention relates to a wastewater treating system and method for removing pollutants of carbon, nitrogen, phosphorous, comprising: a first reactor contains methanogenic bacteria, PAO and denitrifying bacteria for eliminating the organic carbon in denitrification by denitrifying bacteria, adsorbing partial organic carbon and releasing phosphate by PAO and; metabolizing organic carbon to form methane gas by methanogenic bacteria; a second reactor disposed at the rearward of first reactor, second reactor treats the effluent from first reactor by denitrifying bacteria and PAO, denitrifying bacteria is able to denitrifying the nitrate and PAO is able to process the phosphorous releasing; a third reactor disposed rearward of second reactor, which comprises PAO, heterotrophic bacteria and nitrifying bacteria, wherein PAO is applied for phosphorous accumulating process, the heterotrophic bacteria is applied for carbon removal process, the nitrifying bacteria is applied for nitrifying process; and a membra
