Description
Technical Field

Background
Industrially and life, a lot of sewage is produced every day. Some of the sewage is collected in sewage treatment plants for treatment and then discharged into rivers. And more parts are directly discharged into a sewer or a river, so that water resources are greatly polluted. In life, kitchen sewage is one of the important causes of eutrophication pollution of rivers and lakes. On one hand, the domestic sewage is large in quantity and high in treatment cost, and on the other hand, the environmental awareness of people is not high, so that the domestic sewage purifying system is not widely applied. The main components of the kitchen sewage are organic matters such as grease, organic detergents and the like, and particulate matters such as sediment, food residues and the like, and the sewage pollution degree can be judged by detecting the content of the organic matters. Therefore, it is necessary to discharge the purified domestic sewage.
At present, the detection of the content of the organic matters mainly depends on a spectrophotometer, and the working principle is as follows: the total content of the organic matters is indirectly represented by the absorbance of the ultraviolet rays with the wavelength of 254 nanometers, after the ultraviolet rays with the wavelength of 254 nanometers penetrate through water, the organic matters in the water absorb part of the ultraviolet rays, and the higher the concentration of the organic matters is, the higher the intensity of the ultraviolet ray absorption is, so the absorbance of the ultraviolet rays corresponds to the content of the organic matters. Different organic matters have different absorption intensities for ultraviolet rays with different wavelengths, and the content of different organic matters in the water can be approximately analyzed by scanning the absorption intensities of the ultraviolet rays with different wavelengths. And the measurement of the total content, namely the comprehensive index of the content of different organic matters, is mainly embodied on ultraviolet rays with 254 nm wavelength. However, the spectrophotometer itself is an instrument, which is very expensive and very bulky, and above all has a certain obstacle to the use of ordinary people.
