Description

Sewage detection method and device

Technical Field

The invention relates to the technical field of sewage detection, in particular to a sewage detection method and a sewage detection device.

Background

Domestic sewage is wastewater discharged in daily life of residents and mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, shops, public places, industrial enterprise toilets and the like. The pollutants contained in the domestic sewage are mainly organic matters (such as protein, carbohydrate, fat, urea, ammonia nitrogen and the like) and a large amount of pathogenic microorganisms (such as parasitic ova, enteroinfectious viruses and the like). Organic matters existing in domestic sewage are extremely unstable and easily decomposed to generate offensive odor. Bacteria and pathogens propagate in large quantities by taking organic matters in domestic sewage as nutrition, and can cause epidemic of infectious diseases. Therefore, domestic sewage must be treated before being discharged.

At present, water resources in China are deficient, but the phenomenon of water pollution is quite prominent, as cities contain industrial production and daily life of people, the urban sewage is also composed of industrial wastewater and domestic sewage, so that the types of pollutants in the urban sewage are complex, the pollution sources are more, not only can single pollutants cause the pollution of water, but also the pollutants in the water environment can generate chemical reactions, and the complex action mechanisms such as synergistic addition and the like are realized.

In the process of implementing the invention, the inventor finds that at least the following problems in the prior art are not solved: the existing sewage sampling and detecting device can not sample and detect various kinds of sewage at one time when sampling the sewage, and mostly carries out the sampling and detecting at one time in a mode and steps of sampling and detecting at one time; then once the sampled sewage is taken out, the sampled sewage is subjected to illumination decomposition for a long time and is precipitated to change the pH value of the water quality, so that the sampling and detecting accuracy is greatly reduced in the process of detection, and the progress of sewage sampling and detecting is influenced; 2. the means commonly used is the preliminary pH valve of PH test paper detection method detection sample sewage to the pH valve detection time, and the tradition mode mostly is that the staff takes to detect test paper detection end contact sewage, then is detecting time measuring a plurality of sample sewage, and the detection procedure is loaded down with trivial details and check-out time is longer, influences detection efficiency.

Therefore, a sewage detection method and a sewage detection device are provided.
