Embodiment Construction
[0031] Attached below Figure 1-8 Embodiments of the present invention will be described in detail.
[0032] The sample sampling points are sewage treatment plants of urban domestic sewage (3 plants), sewage treatment plants of domestic waste sources (landfill leachate) (1 plant), sewage treatment plants of industrial sewage sources (3 plants) and Sewage treatment plants (1 plant) of special industrial sources (paper mills), a total of 8 different types of sewage treatment plants; samples are the remaining sludge from the biological treatment units of each plant.
[0033] Sample pretreatment. The remaining sludge from each sewage treatment plant was centrifuged for 10 minutes under the condition of a separation factor of 2000 to obtain a supernatant, and the supernatant was filtered with a 0.45 μm filter membrane to remove the suspended matter to obtain the sample to be tested;
[0034] Sample determination. The sample to be tested is put into the cuvette of the three-dimensi...
