| titleOfInvention | Method for measuring specific methanogenic activity of sludge |
| abstract | The invention discloses a method for measuring specific methanogenic activity (SMA) of sludge, belongs to the field of wastewater treatment, in particular relates to the field of wastewater anaerobic treatment and microbial fermentation engineering, and aims to solve the problem that the accuracy is low and trace gases are difficult to collect in the conventional method for measuring the SMA of the sludge. In the method, the methane content is measured once every 2 hours. The method comprises the following steps that first, a singlechip computer control pressure transmitter in a device for measuring the total output of fermented gas monitors the pressure change in a first anaerobic bottle in real time to obtain the total output of the gas; meanwhile, a time relay in a trace gas collection device starts or shuts down the trace gas collection device through an electromagnetic valve, the fermented gas is automatically collected by utilizing a vacuum sampling pipe, the fermented gas collected in the vacuum sampling pipe is injected into a gas chromatograph for performing methane content analysis, the methane yield is obtained according to the relationship between the total output of the fermented gas and the methane content, and the SMA is obtained according to an SMA computing formula. The method is used for wastewater treatment. |
