摘要:
The device for automatic determination of hydrocarbonate buffer, ammonium content and/or the content of organic dry substance from fermentation substrate during fermentation in biogas plant, comprises a reactor in which the fermentation substrate is mixed with organic or inorganic acid for the determination of the hydrocarbon buffer or with a mixture of hydrogen peroxide, organic or inorganic acid and an iron solution for the determination of the content of organic dry substance or with a mixture of mineral lye and a hypochloride for the determination of the ammonium content. The device for automatic determination of hydrocarbonate buffer, ammonium content and/or the content of organic dry substance from fermentation substrate during fermentation in biogas plant by driving out of carbon dioxide and nitrogen through the supply of different reagents and through its subsequent monomeric or volumetric measurement, comprises a reactor in which the fermentation substrate is mixed with organic or inorganic acid for the determination of the hydrocarbon buffer or with a mixture of hydrogen peroxide, organic or inorganic acid and an iron solution for the determination of the content of organic dry substance or with a mixture of mineral lye and a hypochloride for the determination of the ammonium content. The excess acid or mixtures are admitted or dosed one-time or multiple time. The dosing of the acid, the mixture and the fermentation substrate is carried out by pressure or without pressure. The reactor is cleaned with water or another fluid. The fermentation substrate is the substrate out of biogas reactor or pre-fermenter or final storage.
