Embodiment Construction

[0032] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:

[0033] Such as figure 1 A population survey method based on sewage concentration monitoring includes the following steps: S1: Determine the area where the estimated population is located, select a sewage treatment plant in this area, and collect water samples from the sewage plant;

[0034] S2: Select human metabolite ammonia nitrogen and tobacco metabolite cotinine as biomarkers;

[0035] S3: Use the national standard method to measure the concentration of ammonia nitrogen in the sewage. The national standard method stipulates the use of Nessler's reagent spectrophotometry to determine the concentration of ammonia nitrogen in the sewage;

[0036] S31: Configure the reagents required for de...

Abstract

The invention discloses a population size survey method based on sewage concentration monitoring. The method specifically comprises the following steps of S1, determining a region where a pre-estimated popularization size is located, selecting a sewage treatment plant of the region, and collecting water inflow samples of the sewage treatment plant for pretreatment of the samples; S2, selecting a human metabolite of ammonia nitrogen and a tobacco metabolite of cotinine as biomarkers; S3 , measuring the concentration of ammonia nitrogen in measurement sewage by use of a national standard method,wherein the national standard method specifies that the concentration of ammonia nitrogen in measurement sewage is measured by use of a Nessler's Reagent spectrophotometric method; S4, measuring theconcentration of cotinine by use of a liquid chromatography-mass spectrometer or a gas chromatograph-mass spectrometer; and S5, calculating output per capita of the two biomarkers, and calculating bya biomarker method to obtain the popularization size of the region where the sewage treatment plant is located.

Description

technical field [0001] The invention relates to the technical field of population survey, in particular to a population survey method based on sewage concentration monitoring. Background technique [0002] Population survey is an important basis for national management, formulation of population policy, labor and employment policy, education policy, social welfare policy, etc. At present, the most widely used method is the census method. The census law refers to the one-time survey and registration of the national population generally and household by household according to the unified method, unified item, unified questionnaire and unified standard time point within the time specified by the state. . This method can obtain the population more accurately and can reflect the population of permanent residents, but the survey has high economic costs and takes a long time, making it difficult to count the floating population. In addition, the data can only reflect the populat...
