| Abstract: | The application of mesophilic sludge digestion and heat and power co-generation in second-phase project(14×104 m3/d) of Qingdao Maidao WWTP is introduced.The digested sludge is the mixture of primary sludge from chemically enhanced high-efficiency sedimentation tank(Multiflo Trio) and excess sludge from BAF(Biostyr),which has a high biogas production.The biogas produced by mesophilic anaerobic digesters is totally used to power cogeneration.The electricity generated covers over 65% of the power demand of the entire WWTP,and the recovered thermal energy can be used to heat the digesters.The achieved economic benefits are obvious. |
