Embodiment 1

[0020] On a river in Suzhou, such as figure 1 The shown solar powered water monitoring buoy of the present invention detects the COD of river water. The diameter of the floating body of the monitoring buoy is 1.2m, the weight is 150kg, and the height is 2m. There is 1 timer, 1 power switch, and a solar panel with a power of 40w. 3 pieces, 2 pieces of batteries with 66AH capacity, 8L high-pressure gas cylinders are filled with compressed air, and the chemical oxygen demand optical detector detects once every 30 minutes. Before the detection, the gas cylinder is controlled by the air valve to flush the detector and control the air valve Turn it on for 2.5 seconds to flush, and detect the data every half an hour in the river. While the instrument is detecting, manually use the sample cup to collect water samples from the side of the floating body for use in the comparative example, and monitor the results of 15 consecutive data within 450 minutes collected by the buoy. As shown i...

Abstract

The invention relates to a method for detecting chemical oxygen demand by using a solar power water-borne monitoring buoy, which mainly solves the problem that the conventional water-borne monitoring buoy cannot accurately measure the chemical oxygen demand. The method is applied to the solar power water-borne monitoring buoy, the water quality is measured by using an optical detector, a high pressure gas cylinder serves as a gas source, the gas source is controlled by adopting a controller and is reasonably and effectively turned on and off, high-pressure gas flow is generated, and a chemical oxygen demand detector is cleaned, so that the chemical oxygen demand is accurately measured, and the method can be applied to the field of water quality monitoring in rivers, lakes and the sea.

Description

technical field [0001] The invention relates to a method for detecting chemical oxygen demand by a solar-powered water monitoring buoy, which can be used in the field of COD monitoring of water quality in rivers, lakes and seas. Background technique [0002] At present, none of the existing water buoys has integrated chemical oxygen demand monitoring parameters. The main reason is that the traditional chemical oxygen demand measurement is difficult because it needs to add an excess of potassium dichromate standard solution to the water sample before the measurement. Silver salt was used as catalyst in the medium, and after heating and digestion, excess potassium dichromate was titrated with ferrous ammonium sulfate as indicator, and the CODCr value was calculated. Waste liquid will inevitably be generated during the measurement process, which needs to be collected and disposed of. Therefore, this method is generally used in laboratories and water stations, requiring human i...
