Progress of Respirometry in Wastewater Biological Treatment

The consumption of oxygen is the most significant biological response in wastewater biological treatment,and the OUR(Oxygen Uptake Rate) of microorganism can be obtained by respirometry.So the respirometry becomes a valuable means for the theoretical research and process operation administration of wastewater biological treatment.The(progress) of respirometry is reviewed and the advantage and disadvantage of each are evaluated.The basic principle and difficulty in implementation of "ultimate" hybrid respirometer are emphasized and also the drawbacks of simpler hybrid respirometer being used presently are discussed.Finally the implementary approach for the development of hybrid respirometer with higher precision by designing novel systems of reactors and temperature control is put forward and the initial result is shown.
