33、on ditch utilizes biological action to degrade organics in the wastewater. Consideration should be given to wastewaters from industrial facilities to ensure there are no components detrimental to microorganisms. In addition, Army facilities utilizing continuous loop reactors should include pretreatm

34、ent equipment such as bar screens, comminuters and a grit chamber as required by the process conditions. Final clarification, sludge handling and disinfection equipment is also generally required. These and other possible components of the complete treatment system guide are not covered under this s

35、ection.As required for military construction, only sprayed SECTION 46 53 62 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-concrete (shotcrete) or placed reinforced concrete will be acceptable for the basin construction. Clay lined or syntheti

36、c membrane lined basins (even those protected from erosion) are not acceptable.*The work required by this section consists of furnishing and installing a continuous loop reactor (CLR). The system shall be a modified form of the activated sludge process and classified as an extended aeration system.

37、The basin shall be an earthen channel with an impervious sprayed concrete surface reinforced concrete structure, constructed at the depth and configuration indicated. The basin shall include all aeration/mixing equipment, piping, pumps, baffles, weirs and turning walls necessary for proper performan

38、ce and operation.1.2.1 Design Requirements*NOTE: Some states and regulatory agencies require a minimum detention time of 24 hours. Check the governing regulations for activated sludge/extended aeration processes for the project location.Insert average daily and peak daily flow rates and the required

39、 BOD5 removal efficiency. Typically, 90-95 percent removal can be achieved in a continuous loop reactor. Comply with UFC 3-240-09FA to determine design criteria.*Treatment of the wastewater shall be accomplished by contact with the waste activated sludge in the CLR for a minimum of 18 _ hours. The C

40、LR shall be sized for an average daily flow of _ L/second mgd and a peak daily flow of _ L/second mgd. The CLR shall remove a minimum of _ percent of the influent five day BOD at the average daily flow rate and influent five day BOD.1.2.2 Mixing ParametersThe aeration/mixing system selected shall pr

41、ovide the propelling force for circulation and mixing of the basin contents. The aeration/mixing unit(s) shall be sized to maintain an average horizontal velocity of not less than 0.305 _ m/second 1.0 _ fps throughout the basin and maintain a uniform mixed liquor suspended solids (MLSS) concentratio

42、n throughout the basin at MLSS concentrations up to 5000 _ mg/L, with one aeration/mixing device not operating.1.2.3 Aeration Parameters*NOTE: The Actual Oxygen Requirement (AOR) is calculated by the designer. The oxygen required for oxidation of BOD and the oxygen required for nitrification must be

43、 included in the AOR. Typical values are 0.82 kg (1.8 pounds) of oxygen per 0.45 kg (1.0 pound) of BOD applied and 2.1 kg (4.6 pounds) of oxygen per 0.45 kg (1.0 pound) of TKN applied. The alpha coefficient is defined as the ratio of the oxygen transfer in the wastewater to SECTION 46 53 62 Page 8Pr

44、ovided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-the oxygen transfer in clean water and may vary from 0.2 to 1.5. The alpha coefficient is a direct multiplier in determining oxygen transfer capabilities and is affected by mixed liquor temperature, liqui

45、d depth and basin geometry, the level of turbulence, mixing patterns and the nature of dissolved organics and mineral constituents in the wastewater and even the type of aeration equipment. Fine bubble aeration systems typically have lower alpha values than mechanical aeration systems. Because of this variation in alpha value a defa
