Statistical accounting method for effective pollution discharge population based on resident staying duration

Abstract

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

Description

Technical field [0001] The invention belongs to the field of urban drainage and wastewater treatment technologies, in particular to a long-time residents staying statistical accounting method effective population-based sewage. Background technique [0002] Domestic sewage pollutants of urban residents, refers to the daily lives of residents through the process of generating and pollutant emissions from domestic water wash, toilet, bathing, washing, kitchen drainage, accounting per person per day. As a key support basic indicators of urban drainage and sewage treatment project planning, design, operation and performance assessment, access to sewage contamination residents may characterize the true level of actual sewage capacity of urban residents generate the amount of data, for the guidance of my country's urban drainage and sewage treatment works building to enhance the level of industry management, guide the healthy and sustainable development has important practical significa...

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
