Abstract:
Objective To analyze and study the influence of the leachate concentration, pH, inoculation amount and treated time on treatment efficiency with complex microorg anisms.
Methods The high effective complex microor ganisms were domesticated to treat the leachate and the Chemical Oxygen Demand(CODCr)and NH3-N were detected.
Results The pH 6.5~8.5 was suitable for the complex microorg anisms growth.The highest CODCr what the complex microor ganisms could endure was 11 520 mg/L and the best inoculation amount was 5×105 cfu/ml under the condition.The inoculation amount should match the leachate concentration.The complex microorg anisms brought better treatment efficiency for two days in generally, and adding the treated time could be benefit to degrading the CODCr and NH3-N.
Conclusion The complex microorganisms could degrade the CODCr and NH3-N of the leachate well.
