Problems solved by technology

However, because residents have to go to school, work, business trips, shopping and entertainment, etc., and there are often visitors, hourly workers, property personnel, logistics couriers, etc. in and out of the test area, this also leads to the fact that both the permanent population and rough The calibrated population cannot be equal to the real sewage discharge population, and the total amount of domestic sewage pollutants produced does not correspond to the sewage discharge population obtained by the above method. In the end, the test results of the domestic sewage pollutant production of residents are different from the actual level. large deviation
[0004] In actual testing, it is often difficult to ensure that the permanent residents stay in the testing area and do not prevent visitors, hourly workers, property personnel, and logistics couriers from entering the testing area. A statistical accounting method of effective sewage discharge population with scientific methods and accurate results, so as to improve the test accuracy of residents' domestic sewage pollutant production

Embodiment 1

[0050] Embodiment 1: A statistical accounting method for the effective sewage discharge population based on the residence time of residents, comprising the following steps:

[0051] 1) Obtain the initial value R of the number of residents in a test area at 15:00 pm on October 13, 2020 through the household survey 0 = 80 people, and began to test the records of residents' entry and exit at all personnel entrances and exits in the area at 15:00 in the afternoon;

[0052] 2) At 17:00 pm on October 13, 2020, the test on the amount of domestic sewage pollutants produced by residents was officially launched. The test cycle was from 17:00 pm on October 13 to 17:00 pm on October 14. The start and end time of the first test period is from 7:00 to 8:00 am on October 14, 2020; through the records of the residents' entry and exit at all personnel entrances and exits, obtain The number of residents entering and leaving the test area during 7:00 is R 0，进 = 298 people and R 0，出 = 222 peop...

Embodiment 2

[0059] Embodiment 2: A statistical accounting method for the effective sewage discharge population based on the residence time of residents, comprising the following steps:

[0060] 1) Obtain the initial value R of the number of residents in a test area at 15:00 pm on October 13, 2020 through the household survey 0 = 80 people, and began to test the records of residents' entry and exit at all personnel entrances and exits in the area at 15:00 in the afternoon;

[0061] 2) At 8:00 am on October 28, 2020, the test on the amount of pollutants produced in domestic sewage will be officially launched again. The test cycle is from 8:00 am on October 28 to 8:00 am on October 29. It is known that The start and end time of a certain test period is from 9:15 am to 9:50 am on October 28, 2020; through the records of residents' entry and exit at all personnel entrances and exits, the data from 15:00 pm on October 13, 2020 to October 28, 2020 The number of residents who entered and exited ...

Embodiment 3

[0069] Embodiment 3: A statistical accounting method for the effective sewage discharge population based on the residence time of residents, comprising the following steps:

[0070] 1) Re-conduct the household survey to obtain the initial value R of the number of residents in a test area at 10:35 am on November 10, 2020 0 = 65 people, and began to test the records of residents' entry and exit at all personnel entrances and exits in the area at 10:35 am;

[0071] 2) At 16:00 pm on November 10, 2020, the test on the amount of domestic sewage pollutants produced by residents was officially launched. The test cycle was from 16:00 pm on November 10 to 16:00 pm on November 11. The start and end time of the first test period is from 17:08 to 18:25 pm on November 10, 2020; through the records of residents' entry and exit at all personnel entrances and exits, the data from 10:35 am on November 10, 2020 to the afternoon of November 10, 2020 can be obtained. The number of residents ente...

Abstract

A statistical accounting method for the effective pollution discharge population based on resident retention duration comprises the following steps: 1, obtaining resident number initial values of all people in a test area at a certain time point before resident domestic sewage pollutant yield test is started through home-entry investigation, and synchronously starting to record entering time points and leaving time points of all residents entering and leaving the test area; 2, due to starting and ending time of a certain test time period is known, calculating the initial value of the number of residents at the starting point of the test time period; 3, calculating to obtain the total residence duration of entering residents and the total leaving duration of leaving residents; 4, calculating to obtain increased effective pollution discharge population entering the residents and reduced effective pollution discharge population leaving the residents; and 5, calculating the effective pollution discharge population in the test time period. According to the invention, the actual residence duration of residents in the test area is used as an accounting reference, and the method has the advantages of scientific accounting method, accurate accounting result and the like.

Description

technical field [0001] The invention belongs to the technical field of urban drainage and sewage treatment, and in particular relates to a statistical accounting method for the effective sewage discharge population based on the residence time of residents. Background technique [0002] The amount of domestic sewage pollutants produced by urban residents refers to the pollutants produced by residents in their daily life and discharged through domestic water such as washing, defecating, bathing, washing, and kitchen drainage, calculated on a per-capita basis per day. As a key basic index to support the planning, design, operation and performance evaluation of urban drainage and sewage treatment projects, obtaining data on the amount of domestic sewage pollutants that can truly represent the actual level of sewage production and discharge by urban residents is of great importance for guiding my country's urban drainage and sewage treatment projects. It is of great practical sign...
