Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater monitoring, and particularly relates to a water quality monitoring system device and a water quality monitoring method for heavy metal wastewater. Background Art

[0002] The continuous intensification of industrialization and urbanization has led to a gradual increase in the waste gas and wastewater generated by industrial production. Therefore, the treatment of wastewater has become the top priority of environmental protection. Generally, for industrial wastewater, including light and heavy industrial wastewater and heavy metal wastewater, the first step is to conduct tests. After the test results meet the requirements, the wastewater is discharged. Wastewater monitoring usually pays more attention to timeliness. Therefore, if water samples are taken and sent to the laboratory for water quality analysis, and then the results are obtained and delivered, there is often a relatively high delay. Therefore, wastewater detection should be more processed for timeliness;

[0003] After retrieval, a water quality monitoring system device and a water quality monitoring method for heavy metal wastewater with the publication number of CN113607726A in the prior art. The water quality monitoring system device provided by the present invention realizes the integration of the Internet of Things and image analysis technology through the mutual cooperation between multiple devices with specific functions, achieves the purpose of quickly determining the content of different heavy metals in the influent of heavy metal wastewater, starts the alarm state for the over-standard influent, minimizes the probability of the occurrence of the phenomenon that the pollutant emission concentration of heavy metal production enterprises exceeds the standard, improves the stability of the process operation, standardizes the sewage discharge behavior of enterprises in industrial parks, improves the wastewater treatment efficiency, and overcomes the key problems faced by the centralized treatment facilities in industrial parks;

[0004] However, there are still certain drawbacks. This solution does not give specific methods to avoid the problem of mutual fusion and pollution of wastewater during the adjacent water sampling and monitoring processes in multi-batch or multi-region wastewater monitoring; that is, between the previous wastewater sampling and monitoring and the next wastewater sampling and monitoring, the residual wastewater from the previous sampling on the sampling device and the subsequent sampling wastewater are fused, affecting the actual wastewater monitoring results.

[0005] Further retrieval shows that there are also the same drawbacks in an industrial wastewater heavy metal monitoring device with the publication number of CN210142072U and a remote online monitoring device for the heavy metal content of factory wastewater with the publication number of CN213456902U;

[0018] Further, a first scraper is arranged on the inner wall of the water suction bin and on the upper layer of the filter plate to scrape off the sundries on the filter plate.

[0019] Further, a second scraper is provided on the mounting plate and is disposed on the lower layer of the filter plate to scrape off the sundries on the lower layer of the filter plate.

[0020] Further, a spare water storage tank is provided on the support to supply clean water to the water inlet pipe and the backwash pipe.

[0021] A water quality monitoring method for a water quality monitoring system device of heavy metal wastewater is as follows:

[0022] 1) Wastewater collection: First, the first motor drives the pulley to rotate, then drives the first lead screw to rotate, and thus drives the fixed plate and the water suction chamber to move up and down along the guide shaft to meet the water suction requirements; Second, the industrial wastewater is sucked into the detection chamber through the water pump and the water suction chamber; During the wastewater extraction process, the filter plate performs basic filtration on the wastewater, including impurities and sundries in the wastewater.

[0023] Further, when extracting wastewater, open the switch of the drain pipe on the water suction pipe and close the switch on the water suction pipe in the early stage, and discharge the wastewater extracted in the early stage through the drain pipe to perform a preliminary flushing on the water suction part and the front section of the water suction pipe, which can cooperate with the backwash mechanism to achieve more effective cleaning; Then close the switch on the drain pipe and open the switch on the water suction pipe to allow the wastewater to enter the detection chamber.

[0024] Further, the filter plate can also be cleaned by the top-pushing mechanism, the first scraper, and the second scraper to prevent long-term blockage from causing unsmooth water inlet and poor filtration effect; The second motor drives the transmission shaft to rotate, and then drives the filter plate to rotate. First, the first scraper scrapes off the sundries protruding from the top support of the filter plate, and then the conical head of the top shaft on the top-pushing mechanism pushes the filter holes on the filter plate to eject the sundries. When continuing to rotate, the second scraper scrapes off the sundries adhering to the bottom layer of the filter plate and not falling off; After the filter plate is cleaned, the fourth motor controls the second lead screw to rotate, and then drives the socket to move up and down to insert and lock the ear plate of the filter plate to restrict its rotation.

[0025] Further, the backwash mechanism can also clean the inner wall of the water suction chamber: The external water supply system supplies water to the backwash pipe, and when the second motor drives the shunt pipe to rotate, the spray pipe flushes the inner wall of the water suction chamber to clean the wastewater adhering to the inner wall to avoid mixing with the wastewater in different subsequent areas and affecting the monitoring results.

[0026] 2) The wastewater enters the detection chamber through the water suction pipe and the hose for detection; After detection, the wastewater is discharged through the second outlet pipe; The detection results are displayed through the display.

[0027] 3) Cleaning the inner walls of the detection chamber and the treatment chamber: Water is supplied into the inlet pipe through the external water supply system, and then the surface of the partition plate and the inner wall of the box are flushed through the first spray pipe and the second spray pipe, so as to prevent the attached wastewater from mixing with the wastewater of the subsequent batches and resulting in inaccurate detection results. The flushing wastewater is discharged through the first outlet pipe and the second outlet pipe;

[0028] 4) Adjusting the detector; When the detector is damaged and needs to be replaced or repaired, the third motor drives the adjusting arm to rotate, and then the support columns on the two groups of detectors are controlled to move along the adjusting groove through the adjusting groove, and finally the detector moves along the guide rail, so that the detector moves between the detection chamber and the treatment chamber.

[0029] The beneficial effects of the present invention compared with the prior art are as follows:

[0030] 1) In this solution, a water absorption part is provided and can be backflushed through the backwashing mechanism to flush the inside of the water absorption chamber to prevent the wastewater attached to the inner wall from cross-mixing with the wastewater extracted subsequently, so that the true pollution situation of the wastewater extracted subsequently cannot be truly monitored, and inaccurate monitoring results are obtained; During the backwashing process, the second motor drives the transmission shaft to rotate, and then drives the shunt pipe and the spray pipe to rotate, so that the spray pipe sprays water and can evenly clean the inner wall of the water absorption chamber, achieving the above effects;

[0031] First of all, a pair of spray pipes are provided and symmetrically arranged, and in cooperation with the shunt pipe, a "U" shape can be formed. Secondly, spray heads are provided on the outer circle and the top of the spray pipe. Through the rotation of the shunt pipe, the branch pipes can be driven to rotate around the shunt pipe as the axis, so that the inner wall of the water absorption chamber and the outer wall of the water suction pipe can be backflushed at 360°. When the shunt pipe rotates one week, it can ensure that the water absorption chamber can be flushed at least twice, ensuring that the wastewater adhering to the inner wall of the water absorption chamber and the outer wall of the water suction pipe can be cleaned and backflushed, thus avoiding cross-mixing pollution of the wastewater;

[0032] 2) A movable filter plate is provided at the port of the water absorption chamber of the water absorption part. When there are a lot of sundries on the filter plate, the filter plate can also be cleaned through the cooperation of the top pushing mechanism, the first scraper and the second scraper, to prevent long-term blockage from causing unsmooth water inlet and poor filtering effect; During this process, the second motor drives the transmission shaft to rotate and then drives the filter plate to rotate. First, the sundries protruding from the top support of the filter plate are scraped off by the first scraper, and then the conical head of the top shaft on the top pushing mechanism pushes the filter holes on the filter plate to eject the sundries. When it continues to rotate, the sundries adhering to the bottom layer of the filter plate and not falling off are scraped off by the second scraper to clean the filter plate; Further, after the filter plate is cleaned, the second motor controls the second lead screw to rotate, and then drives the socket to move up and down to insert and lock the ear plate of the filter plate, restricting its rotation and keeping it stable;

[0033] 3) When the detector needs to be replaced or repaired due to damage, the third motor drives the adjustment arm to rotate, and then through the adjustment groove, the support columns on the two detectors are controlled to move along the adjustment groove, and finally the detector moves along the guide rail, realizing the reciprocating movement of the detector between the detection chamber and the processing chamber. Moreover, their opposite movements are simultaneous, so that the detector can continuously work without interruption of heavy metal wastewater monitoring due to maintenance and replacement, ensuring the timeliness of wastewater monitoring. Further, the box body can also be fixed on an external vehicle for movement, enabling rapid transfer and realizing rapid and effective monitoring of wastewater discharged in different regions and batches.

[0034] Among them, during the process of the detector moving along the guide rail relying on the support shaft, the detector rises along the guide rail convex part at the partition position along the guide rail, and then gradually descends after entering the processing chamber. The setting of the convex part of the guide rail can prevent the partition and the first spray pipe from interfering with the moving detector, enabling the detector to smoothly enter the processing chamber from the detection chamber, thus enabling the smooth completion of the detector's overhaul. Further, during the movement of the detector on the guide rail, the up and down sliding of the support column in the sliding sleeve can always keep the detector stable and prevent the detector from rotating along the support shaft. At the same time, the sliding sleeve cooperates with the third limit plate to keep the sliding sleeve itself stable, thereby stably supporting the support column and the detector. Finally, the detector is controlled by the adjustment arm to move smoothly and steadily between the detection chamber and the processing chamber. Description of the Drawings
