Embodiment 1

[0057] like figure 1 Shown, a method for monitoring the degree of pollution of a river with a lot of sediment, the method includes the following steps:

[0058] S1. Prepare the water intake tank: Use the air pump to vacuumize the sealed empty tank to eliminate the influence of air on the river monitoring data;

[0059] S2. Take water: extend the lower end of the pumping pipe to the required depth in the water surface of the river, select different sampling depths, open the first valves in turn, and take water samples;

[0060] S3. Stirring sampling: after the extraction is completed, close the first valve, turn on the stirring motor, after stirring time T, turn off the stirring motor, and then turn off the air pump, so that the return air in the sealed empty box returns to the normal atmospheric pressure state, open the third valve, from Sampling in the sampling tube;

[0061] S4. Sending samples for detection: send the removed water samples to the water quality testing labo...

Embodiment 2

[0067] like figure 1 Shown, a method for monitoring the degree of pollution of a river with a lot of sediment, the method includes the following steps:

[0068] S1. Prepare the water intake tank: Use the air pump to vacuumize the sealed empty tank to eliminate the influence of air on the river monitoring data;

[0069] S2, water intake: extend the lower end of the pumping pipe to the required depth in the water surface of the river, select different sampling depths, open the first valve in turn, and use atmospheric pressure to draw the river water into the sealed empty box to extract water samples;

[0070] S3. Stirring sampling: after the extraction is completed, close the first valve, turn on the stirring motor, after stirring time T, turn off the stirring motor, and then turn off the air pump, so that the return air in the sealed empty box returns to the normal atmospheric pressure state, open the third valve, from Sampling in the sampling tube;

[0071] S4, sample delive...

Embodiment 3

[0084] like figure 1 As shown, a method for monitoring the degree of pollution of a river with a lot of sediment, the method includes the following steps:

[0085] S1. Prepare the water intake tank: Use the air pump to vacuumize the sealed empty tank to eliminate the influence of air on the river monitoring data;

[0086] S2, water intake: extend the lower end of the pumping pipe to the required depth in the water surface of the river, select different sampling depths, open the first valve in turn, and use atmospheric pressure to draw the river water into the sealed empty box to extract water samples;

[0087] S3. Stirring sampling: after the extraction is completed, close the first valve, turn on the stirring motor, after stirring time T, turn off the stirring motor, and then turn off the air pump, so that the return air in the sealed empty box returns to the normal atmospheric pressure state, open the third valve, from Sampling in the sampling tube;

Abstract

The invention discloses a method for monitoring the pollution level of a sediment-laden river. The method comprises the following steps: (S1) preparing a water-extracting tank: starting an air pump soas to vacuumize a sealed hollow tank; (S2) extracting water: enabling the lower end of a water pumping pipe to stretch into the water level to a certain depth, and sequentially opening a first valve,and extracting a water sample at different sampling depths; (S3) after the extraction is finished, closing the first valve, starting a stirring motor, stirring for 1-2 minutes, stopping the stirringmotor, closing an air pump, returning air into the sealed hollow tank to restore the sealed hollow tank to a normal-pressure state, opening a third valve, and extracting the sample from a sampling pipe; and (S4) detecting the water sample: selecting different volumes of water samples according to the scales on a glass measuring cylinder, mixing the water samples extracted from different depths ina proportion, conveying the water samples into a water-quality detection laboratory, and carrying out oxygen demand detection. According to the method, the water samples at different water layers of the river are collected, are reasonably taken out in a proportion (between the heights of different water layers and the total number of the water layers), are prepared into a homogenized water sampleand are detected, so that the detection data is relatively accurate.

Description

technical field [0001] The invention belongs to the field of river pollution degree monitoring technology in environmental protection, and in particular relates to a method for monitoring the pollution degree of rivers with many sediments. Background technique [0002] With the continuous development of industrialization and people's living standards, there are more and more industrial wastes and domestic wastes, and a large part of them are directly discharged into the river without environmental protection and harmless treatment, which leads to the pollution of the river. Pollution. [0003] In order to monitor the degree of pollution of the river and provide data support for the prevention and control of river pollution, the following technical solutions are often used in the prior art: [0004] Chinese patent application 201110046575.3 discloses a method for real-time diagnosis of river pollution, which includes: river pollution diagnosis platform, pollution degree eval...
