Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pollution detection, and particularly relates to a solute detection instrument for water body pollutants. BACKGROUND

[0002] With the acceleration of industrialization and urbanization, a large amount of chemical substances in the form of ions, molecules or colloids enter rivers, lakes and underground water, forming so-called "solute pollutants", that is, existing in dissolved state in water body, such as nitrate, heavy metal ions, and pharmaceutical active ingredients. Since these substances are colorless and odorless, and diffuse rapidly, it is difficult to identify their existence and concentration change by traditional visual or sensory means. Once the accumulation exceeds the specified interval limit, it will cause potential risks to the ecological system and human health. Therefore, it is necessary to determine the concentration level of these dissolved substances by a water quality detector. Generally, the probe of the water quality detector is used to detect the water body to be detected in the water body, so as to obtain the concentration value of the solute pollutants in the water body.

[0003] In the natural water environment, in addition to the existence of solute pollutants, there are also a large number of suspended pollutants. Among them, blue algae as an important part of suspended substances are widely distributed in water body. When the content of solute pollutants in water body increases, it will provide sufficient nutrients for the growth and reproduction of blue algae, and then promote the large-scale breeding of blue algae. In the process of large-scale breeding of blue algae, oil film-like floating objects often cover the surface of water body. In natural water area, the places with more oil film distribution indicate that there are more solute pollutants in the water body in this area. Generally, the solute pollutants in this area are detected by water quality detector through water pump.

[0004] When detecting the water quality of the water body covered with oil film, such oil film will interfere with the optical detection probe of the water quality detector. Specifically, the oil film will directly block the detection light path of the probe, so that the light cannot be transmitted along the expected path. For the optical detection probe, the oil film will also absorb, reflect or scatter the detection light, thereby changing the light intensity reaching the target solute in the water body, and then affecting the accurate acquisition of the detection signal. In addition, long-term contact with the oil film will gradually form a deposition layer on the surface of the probe. Even if the oil film is temporarily removed, the residual pollutants will still continuously interfere with the subsequent measurement process. However, the existing water quality detector lacks effective processing methods to deal with the above problems, so that the detection result cannot accurately reflect the concentration of solute pollutants in the water body.

[0005] To solve the above problems, the solute detection instrument for water body pollutants is provided in the present application. SUMMARY

Meanwhile, the extrusion of the guide wheels 743 can remove the water attached to the connecting position of the clamping groove, so that the sample precision of the felt oil film 401 in the process of circulation detection is not affected.

[0065] As shown in Figure 2 , Figure 3 and Figure 4 , in the embodiment, the bottom of the box body 1 is connected with a water outlet pipe 104, the water outlet pipe 104 is provided with a valve, the box body 1 is provided with a water level sensor 102 for monitoring the water level, the back of the box body 1 is provided with a controller 103, the water level sensor 102, the motor 221, the air pump 326, the water quality detector 5, the control valve 61, the water supply pump 73 and the valve are electrically connected with the controller 103.

[0066] The water level sensor 102 is used to monitor the water level in the box 1, and when the water level in the box 1 rises to the position of contact with the felt oil film 401, a signal is transmitted to the controller 103, and the controller 103 controls the water pump 81 to stop pumping water according to the water level information and the preset program. In the subsequent working process, the controller 103 can control the start and stop and operating state of the motor 221, the air pump 326, the water quality detector 5, the control valve 61, the water supply pump 73, the water outlet pipe 104 valve and other components, realize automatic control of the equipment, reduce manual operation, and improve the detection efficiency and stability.

The cleaned sewage can be discharged through the first sewage pipe 311, and the residual sewage in the box 1 can be discharged through the water outlet pipe 104.

[0068] In specific embodiments, the main component of the felt oil film 401 is usually a hydrophobic substance, which has a low surface tension and can quickly spread on the surface of the water body to form a thin film. The formation of this film enables the felt oil film 401 to effectively cover the surface layer of the water body, thereby more effectively adhering to the oily substances on the surface layer of the water body.

[0069] In specific embodiments, it is particularly noted that in actual use, the device can extract water bodies at different positions and depths in the water area through the water pump 81 (the water extraction end of the water pump 81 is connected to the pipe to extend into water bodies at different positions and depths in the water area) according to actual needs, to realize large-area sampling, and the probe 51 on the water quality detector 5 is used for preliminary rapid detection to record initial data. In order to make the detection data more accurate, after sampling the water bodies at different positions and depths in the water area and cleaning the existing oil film, a sampling container can be placed at the bottom of the drain pipe 6 to collect the water bodies for subsequent chemical analysis and comparison with the initial detection of the water quality detector 5 to ensure the accuracy of the data. At the same time, through this preliminary detection method, it can be quickly and accurately known which part of the water area has a large difference from the standard water quality, and the water sample with a large difference can be timely stored for subsequent further refined detection. Targeted sampling reduces the number of samples and reduces the work intensity. And by sampling the water discharged from the drain pipe 6, subsequent refined detection can be directly performed, which saves the operation of removing and filtering a large number of samples one by one.

[0070] The specific working principle of the present application is as follows:

[0071] The water pump 81 draws the water to be detected to the separation cylinder 22 through the water guide pipe 82, the motor 221 drives the shaft rod 223 to rotate the auger 222, the larger impurities in the water are transported to the impurity discharge pipe 224 by the auger 222, and the preliminarily filtered water enters the separation box 21 through the first filter hole, and then enters the filter cylinder 31 through the water guide pipe 211;

At the same time, the shaft rod 223 drives the main rotating rod 42 to rotate through the first transmission member 45, the main rotating rod 42 drives the aeration pipe 321 to rotate through the second transmission member 46, the air pump 326 supplies air to the aeration pipe 321 through the air inlet pipe 325 and the rotating joint 324, the gas is discharged from the aeration holes 323 to realize aeration, the water is stirred by the stirring plate 322 to prevent the impurities from depositing, and the water bubbles generated during aeration can make the oily substances in the sewage better suspended on the surface layer of the water. When the water level sensor 102 detects that the water reaches the preset height and contacts the felt oil film 401, the controller 103 controls the water pump 81 to stop pumping water;

[0073] The main rotating rod 42 drives the main pulley 421 to rotate, drives the vice pulley 431 and the vice rotating rod 43 to rotate through the synchronous belt 44, and makes the felt oil film 401 move circularly on the surface layer of the water to adsorb the oil stains on the surface layer. When the felt oil film 401 passes through the scraping plate 72, the oil stains are scraped to the collection box 71, the water pump 73 supplies water to the joint through the water supply pipe 731, the flushing pipe 732 and the cleaning nozzle 733, and the waste liquid is discharged from the second sewage pipe 711;

[0074] After the water in the box body 1 is treated, the control valve 61 is opened, the water is filtered into the drain pipe 6 through the filter disc 62, the probe 51 of the water quality detector 5 detects the concentration of the soluble substances in the water, after the detection is completed, the controller 103 controls the valve of the water outlet pipe 104 to be opened, the remaining water in the box body 1 is discharged, and the first sewage pipe 311 can discharge the impurities in the filter cylinder 31;
