Online monitoring device and method for water pollution

Abstract

The invention provides an on-line monitoring device for water pollution. The device comprises a sampling unit and a monitoring unit, wherein the sampling unit comprises an underwater monitoring tank, sensors and a telescopic rod; the monitoring unit comprises a housing, controllers, a power source, a remote monitoring data acquisition card, a peristaltic pump and a water sample barrel; the two units are connected with a water pipe through cables; the sensors can be placed in the underwater monitoring tank or the water sample barrel according to the water condition; a plurality of sensors and a water pipe inlet are arranged in the underwater monitoring tank, and sampling and monitoring of water at different depths are completed by the telescopic rod; the controllers receive and process signals of the sensors, data is wirelessly transmitted to an industrial computer or a mobile phone by the remote monitoring data acquisition card, and accordingly, real-time on-line monitoring of the water pollution is realized; the peristaltic pump draws a water sample forward to the water sample barrel through the water pipe and flushes the sensors backward; the housing of the device is portable, and a fixed or photovoltaic power supply is used for supplying power. The invention further provides an on-line monitoring method for the water pollution.

Description

technical field [0001] The invention relates to the field of water body pollution monitoring, in particular to a water body pollution online monitoring device and method in the fields of black and odorous water body online monitoring and discrimination, water body pollution emergency detection and treatment, and water quality field monitoring. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, a large amount of industrial wastewater, domestic sewage and other wastes have entered rivers, lakes, seas and other water bodies, which exceeds the self-purification capacity of natural water bodies and causes pollution, which will lead to physical pollution of natural water bodies. Changes in chemical, biological and other characteristics will affect the use value of water, endanger human health or destroy the ecological environment, resulting in the deterioration of water quality.

AI Technical Summary

Problems solved by technology

[0004] At present, most of the monitoring of water bodies and their water quality in my country adopts the method of "on-site sampling, laboratory testing, and manual analysis". There are also a small number of fixed laboratories on the shore and movable sampling devices. There is a certain time difference with the results, that is, real-time online monitoring and data analysis cannot be carried out, and the monitoring range is limited because the monitoring device cannot be moved arbitrarily, and technical support and guarantee for water pollution prevention and treatment cannot be provided in time

Existing water quality monitoring equipment and systems are no longer suitable for use in fields such as black and odorous water monitoring and discrimination, emergency detection and treatment of water pollution, and field water quality monitoring that require high monitoring and response.
