System and method for checking standard exceeding of water quality

Abstract

The disclosure provides a water quality standard exceeding checking system, comprising: an equipment unit (100), drained water respectively entering a water inlet tank (101) from at least two water inlet ends for water quality homogenization and sending a water sample to an online monitoring instrument unit (200); an online monitoring instrument unit (200) which comprises a primary settling tank (108), a sampler (113) and a water quality analyzer (119), and is used for performing water quality test analysis after the water sample is settled; and an automatic sampling unit (300) which is used for sampling and storing drained water at each water inlet end; when the on-line monitoring instrument unit (200) tests and analyzes that the water quality exceeds the standard, samples sampled and retained at the standard exceeding moment are tested and analyzed, and the water inlet end with the water quality exceeding the standard is determined. The invention further provides a water quality standard exceeding checking method.

Description

technical field [0001] The disclosure relates to the technical field of sewage treatment, in particular to a system and method for checking water quality exceeding standards. Background technique [0002] In the construction of water environment safety in industrial parks, it is very important to do a good job in environmental supervision and management of industrial pollution sources. Although industrial parks basically have centralized sewage treatment facilities, there are inevitably problems such as illegal production, excessive sewage discharge, and weak environmental protection supervision during operation. , leading to poor operational stability and low treatment efficiency of the centralized sewage treatment plant, and constant hidden dangers to the water environment in the park. [0003] As a means of automatic monitoring of pollution sources, the online monitoring system of sewage water quality can effectively promote the standardized construction of sewage dischar...

Problems solved by technology

[0002] In the construction of water environment safety in industrial parks, it is very important to do a good job in environmental supervision and management of industrial pollution sources. Although industrial parks basically have centralized sewage treatment facilities, there are inevitably problems such as illegal production, excessive sewage discharge, and weak environmental protection supervision during operation. , leading to poor operational stability and low treatment efficiency of the centralized sewage treatment plant, and constant hidden dangers of water environment safety in the park

[0003] As a means of automatic monitoring of pollution sources, the online monitoring system of sewage water quality can effectively promote the standardized construction of sewage discharge in enterprises, ensure the quality of sewage treatment in sewage plants, improve work efficiency, and better improve the water environment in industrial parks. The use of some online monitoring systems only stays in terminal drainage monitoring, and only a few major pollution source enterprises have online water monitoring systems. Systematic management methods, when the water intake of the centralized sewage plant in the park exceeds the standard, it is difficult to find out the enterprises that exceed the standard, making environmental law enforcement difficult and heavy tasks
