Water quality on-line monitoring automatic quality control system

Abstract

A water quality on-line monitoring automatic quality control system comprises a quality control management server and an automatic quality control terminal device; the automatic quality control terminal device comprises a sample-transferring standard-adding device and a controller; the controller is connected with the sample-transferring standard-adding device. The invention cleans a water sampletransportation pipeline and a storage container timely, and collects waste water for treatment or recycle, which ensures the accuracy of water sample preparation, meets container cleaning standards of laboratories in our country, recovers waste water from cleaning, and prevents secondary pollution by waste water from cleaning; with methods of repeated sample transfer and metered standard-added sample transfer, results obtained from two mechanical detections by the external water quality monitoring system are analyzed by comparison or are analyzed by difference calculation; the detection precision and accuracy of the external water quality monitoring system are effectively reflected; and the detection experiment performance of the external water quality monitoring system is accurately evaluated.

Description

technical field [0001] The invention relates to an experimental evaluation system for the quality of data generated by an automatic detection instrument system, in particular to a quality control evaluation system for the quality of experimental data generated by the operation of the water quality online monitoring and detection equipment system, which belongs to the technical field of detection. Background technique [0002] As of 2009, my country's pollution source online detection system has built 324 monitoring centers across the country, installed online detection systems for 9,517 enterprises, achieved certain detection results, realized the management of excessive and illegal emissions, and achieved environmental benefits. [0003] However, there are still some defects and deficiencies in the automatic monitoring of water pollution sources. The quality control methods of on-site testing instruments are insufficient, and there are no guarantees for the testing quality o...

Problems solved by technology

In terms of quality control, it is mainly laboratory comparison tests. The calibration of monitoring instrument systems mainly uses laboratory comparison tests to assess the quality of monitoring instrument systems. There is no standardized and periodic calibration operation, and it takes up a lot of manpower. and time, easy to implement and perform enough in actual operation

On the other hand, at present, the system integration with the detection site is mainly used to retain samples exceeding the standard, and the data exceeding the standard is collected for sample processing, and there is a lack of post-retained sample processing and data evaluation functions with the detection system.
