Problems solved by technology

[0011] The present invention can overcome the shortcomings of the existing methods and devices for monitoring the total amount of pollutants, such as the long sampling interval, the difficulty of scientifically and accurately measuring the total amount of pollutant discharge, and thus the inability to effectively monitor and supervise the over-discharge and stealth discharge behaviors of pollutant-discharging enterprises. Using scientific sampling methods and shortening the sampling time interval, on the one hand, sewage samples can accurately reflect the real situation of sewage pollutant discharge, improve the real-time sampling and the scientific and accuracy of monitoring results; on the other hand, ensure the accuracy of total sewage discharge monitoring Under the premise, it can reduce the detection frequency of relevant indicators and effectively reduce the monitoring cost

Embodiment Construction

[0032] An intelligent measurement method for the total discharge of water pollutants. Based on the existing monitoring system for the total discharge of pollutants, the sewage COD, NH 3 - N and other pollutant discharge amount is intelligently monitored, and its on-site monitoring terminal structure is as follows: figure 2 shown.

[0033] Such as figure 2 , the on-site monitoring terminal includes intelligent proportional sampling controller 2, flow meter 1, integrated sewage storage tank 4, sewage sample electronic control sampler 3, environmental protection data acquisition instrument 5 (including GPRS communication module 6), COD (chemical demand Oxygen) Tester 10 and NH 3 -N (ammonia nitrogen) tester 11.

[0034] The specific monitoring process includes the following steps:

[0035] 1. Flow meter 1 measures the instantaneous flow q(t) and cumulative flow Q of the discharged sewage i ;

[0036] 2. With 5 minutes as a sampling period Δt, the sampling coefficient k of...

Abstract

The invention discloses an intelligent measurement method for the total emission of the water pollutants. In a sampling period Delta t ranging from 5 minutes to 30 minutes, sewage is continuously and automatically sampled in regular time and uniformly mixed according to flux Qi; 24 hours (or 48 hours) are taken as an analysis period Delta T, the consistency of the pollutants is detected by a pollutant online measurement instrument as shown in formula (III), and the total emission of the pollutants in the analysis period can be worked out as shown in formula (I) and formula (II). The intelligent measurement method of the invention can improve the real-time of sampling and the science and accuracy of the monitoring result, can reduce the detection times of relative indexes, and effectively reduce the monitoring cost. When the intelligent measurement method of the invention is used for improving the existing pollutant total quantity monitoring system, the problems of overproof emission by stealth, excessive emission, and unscientific calculation of the total emission of the enterprise pollutants, etc., which exist in some current enterprises can be solved, and the environmental protection monitoring and the law enforcement level can be effectively improved.

Description

technical field [0001] The invention relates to a method for measuring water pollutants, in particular to an intelligent method for measuring the total discharge of water pollutants. Background technique [0002] The implementation of total pollution discharge control is a major change in my country's environmental management system, and it is necessary to ensure the realization of the goals of the "Ninth Five-Year Plan" period and the 2010 national cross-century green project plan. The total amount of pollutant discharge control is based on the results of pollutant source monitoring monitoring. With the implementation of the total amount control work, the monitoring of pollution sources will change from the previous concentration monitoring to the total amount monitoring, which puts forward new requirements for the monitoring work. [0003] The monitoring of the total amount of sewage pollutants provides a scientific basis for the control of the total amount of pollutants,...
