Multi-parameter water quality online monitoring system with self-cleaning function

Abstract

The invention provides a multi-parameter water quality online monitoring system with a self-cleaning function. The system comprises a control and analysis display module, a water pump, a cleaning water pump, a cleaning air pump, a three-way valve, a multi-position valve, a first water guide pipe, a second water guide pipe, circulating grooves and a water outgoing pipe; the control and analysis display module realizes the communication of the water pump, the first water guide pipe, the circulating grooves, the second water guide pipe and the water outgoing pipe or realizes the communication ofthe outlet of the three-way valve, the second water guide pipe, the circulating grooves, the first water guide pipe and the water outgoing pipe by controlling the valve position switching of the multi-position valve; a water quality monitoring sensor is arranged in each circulating groove; and the control and analysis display module is connected with the water quality monitoring sensors and used for reading water quality monitoring data signals outputted by the water quality monitoring sensors, conducting statistics, analysis and management and uploading the water quality monitoring data to amonitoring platform through a wireless transmission module.

Description

Technical field [0001] The invention relates to the field of water quality monitoring, in particular, to a multi-parameter water quality online monitoring system with a self-cleaning function. Background technique [0002] The existing municipal drinking water quality monitoring mainly relies on two methods: manual sample delivery and online testing. Manual sample delivery means that the staff collects the water sample and sends it to the inspection agency for testing, or the inspection agency personnel bring portable testing equipment to the site for sampling For detection, this has disadvantages such as poor effectiveness and high cost; traditional online detection mostly uses separate sensors for water sample monitoring, such as figure 1 As shown, each sensor needs to be equipped with a meter, which occupies a large space, is costly, and is not conducive to the unified management and processing of data; and because the flow rate of the water sample to be tested is slow during t...

[0002] The existing municipal drinking water quality monitoring mainly relies on manual sampling and online detection. Manual sampling means that the staff collects water samples and sends them to the inspection agency for testing, or the personnel of the inspection agency take portable testing equipment to the site to take samples This has disadvantages such as poor effectiveness and high cost; traditional on-line detection mostly uses separate sensors for water sample monitoring, such as figure 1 As shown, each sensor needs to be equipped with a meter head, which occupies a large space, is costly, and is not conducive to the unified management and processing of data; and because the flow rate of the water sample to be measured is slow during the measurement process, it is easy to be trapped in the pipeline and the sensor. A certain amount of dirt is deposited, which requires regular cleaning and maintenance by personnel, which further increases the cost
