Abstract

The invention discloses a device for measuring thicknesses of an aerobic layer and an anaerobic layer of a biological film and a measuring method. The method comprises the steps that a wide-mouth bottle for containing waste water and a biological film testing tank are adopted; oxygen is charged into the wide-mouth bottle, so as to adjust the dissolved oxygen concentration of the waste water; after the dissolved oxygen concentration of the waste water in the wide-mouth bottle reaches a set value, the waste water is led into the biological film testing tank; after the waste water concentration in the wide-mouth bottle and the biological film testing tank reaches an experimental value, the biological film is put into the biological film testing tank; the concentration distribution of micro dissolved oxygen inside the biological film is measured through a dissolved oxygen microelectrode; and the thicknesses of the aerobic layer and the anaerobic layer of the biological film are calculated.

Description

technical field [0001] The invention relates to the field of electrochemical analysis, in particular to a device and a measuring method for measuring the thickness of an aerobic layer and anaerobic layer of a biofilm. Background technique [0002] In the biofilm wastewater treatment process, the biofilm wastewater treatment layer consists of an aerobic layer and an anaerobic layer. The biological denitrification treatment of wastewater, whether it is the traditional nitrification and denitrification biological denitrification process or the new biological denitrification process (such as SHARON process, ANAMMOX process, etc.), will have an aerobic and anaerobic process. The oxidation of ammonia mainly occurs in the aerobic layer of the biofilm. When the concentration of dissolved oxygen in the environmental solution and the hydraulic conditions are constant, the greater the mass transfer resistance of oxygen in the biofilm, the smaller the thickness of the aerobic layer, and...
