Problems solved by technology

However, it is often difficult to meet this requirement through manual monitoring and processing.
Moreover, the traditional manual sampling monitoring method has great randomness
For example, automatic surface water monitoring stations can usually only monitor whether the water quality

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The invention accurately locates the sewage outlet through real-time detection of water pollution, and comprehensively considers the influence of the complex environment of the river course. That is, the present invention uses mobile monitoring components to sample parameters of normal water quality as standard parameters of pollution-free water quality. After being put into normal operation, the mobile monitoring components will cruise in the river for a long time. During the cruising process of the mobile monitoring component, if the water quality of the river is detected to be polluted, a certain cross-section of the river (vertical to the river bank) is detected. If the concentration of pollutants detected in the same cross-section remains unchanged, it means that the distance between the mobile monitoring part and the ill...

Abstract

A method for positioning an illegal sewage outfall. A mobile monitoring component with a water quality sensor is placed in a riverway for cruise; and during the cruise, if the water quality sensor detects pollution of the river water quality, a detection on any cross section of the riverway is carried out. If concentration of pollutants detected in the same cross section maintains the same, it shows that the mobile monitoring component is far from an illegal sewage outfall; then a one-dimensional water quality model is utilized to estimate a distance between the mobile monitoring component and the illegal sewage outfall; and the mobile monitoring component is sent to the estimated position in the riverway. If concentration pollutants detected in the same cross section changes, it shows that the mobile monitoring component is near to the illegal sewage outfall; then a Z-shaped search path method based on changes of pollutant concentration values is utilized for accurate positioning of an illegal sewage outfall. The invention has the advantages of simple principle, high degree of intelligence, stability, reliability and accurate positioning.

Description

technical field [0001] The invention mainly relates to the field of water quality monitoring, in particular to a positioning method for searching illegal sewage outlets. Background technique [0002] Water pollution directly threatens human health, will destroy the ecological environment, and restrict the sustainable development of economy and society. Nowadays, the causes of water pollution problems are very extensive, including the discharge of industrial wastewater and the discharge of domestic sewage. Although the government regulates the sewage discharge behavior of enterprises, some enterprises secretly discharge industrial wastewater in order to save the cost of wastewater treatment. The government is hard to guard against these illegal activities, because these companies often use hidden pipelines for discharge, and these secret channels are difficult to be discovered by people. This kind of company has been secretly discharging for more than ten years until it is d...
