Detailed Description
The following will describe embodiments of the present application in detail with reference to the drawings and examples, thereby how to apply technical means to the present application to solve technical problems, and realizing processes achieving corresponding technical effects can be fully understood and implemented accordingly. The embodiments and the features in the embodiments can be combined with each other on the premise of no conflict, and the formed technical schemes are all within the protection scope of the application.
The currently common methods for detecting the sand content mainly comprise three methods: drying, displacement and photoacoustic wave methods.
The drying method comprises the following processing steps: firstly, measuring the volume of a water sample, precipitating a concentrated water sample, drying and weighing a drying cup, and pouring the concentrated water sample into the drying cup; then the temperature of the oven is set to be not more than 100 ℃ and baked for about 10 hours, and the oven is cooled after being dried; and finally, the mass of the sediment is called.
The time required for measuring the sand content once by the drying method is more than 10 hours, and an oven, a beaker and other instruments are required. Disadvantages of this method include: the measuring period is long, and the instrument and equipment are not easy to carry.
The treatment steps of the displacement method comprise: sampling by using a gravity bottle, measuring the mass of muddy water by using a precision electronic balance after the gravity bottle is full of muddy water, and calculating the sand content according to the density difference of sediment and water.
The displacement method needs a precise electronic balance, has extremely high requirements on measurement precision, is difficult to accurately level outdoors, and is extremely easy to have inaccurate detection results when detecting water bodies with low sand content.
The processing steps of the photoacoustic wave method comprise: the instrument is used for emitting light or sound waves, the turbidity of the water body is calculated according to the reflection of the light or sound waves, and then the relation between the turbidity and the sand content is established, so that the sand content is obtained.
The relation between the sand content and the sediment grading measured by the photoelectric acoustic method is large, and the relation between the turbidity and the sand content is required to be re-rated according to the sediment grading every time, otherwise, the problem of large deviation of the measurement result is caused.
In view of the foregoing, there is a need for a device that is convenient to carry, simple to operate, and capable of efficiently and accurately detecting the sand content in water bodies such as rivers, reservoirs, lakes, etc.
