[0039] When using the pollutant concentration monitoring device for the whole process of sewage treatment process provided by Example 1 of the utility model, the connecting pipe 11 is placed at the junction of each sewage treatment process, the sewage inlet and the sewage outlet, the pH adjustment device 21 and the temperature adjustment device 22 are placed at each sewage process treatment, the first assembly plate 211 and the second assembly plate 221 are fixed to the sewage treatment tank, so that the first mixer 213, the second mixer 214, the pH detector 215, the temperature sensor 222 and the electric heating component 223 can all be in contact with the sewage; when the sewage enters the treatment link, the sewage passes through the connecting pipe 11, and the water quality sensor 12 in the connecting pipe 11 can monitor the pH value, temperature and the concentration of various pollutants. When the pH value and temperature are not within the set range, the water quality sensor 12 feeds back the pH value and temperature to the control The controller 13 controls the pH adjusting device 21 and the temperature adjusting device 22 to adjust the pH value of the sewage.

At the same time, the temperature sensor 222 continuously monitors the temperature in the sewage treatment pool until the temperature in the sewage treatment pool meets the set range, thereby adjusting the temperature in the sewage treatment pool.

[0041] like Figure 5 and Figure 8 As shown, the pollutant concentration monitoring device for the whole process of sewage treatment process provided by Example 1 of the utility model is preferably, in order to control the pH value in the sewage treatment pool, the two storage tubes 2121 are respectively loaded with an acidic regulator and an alkaline regulator; a two-position three-way valve 2123 is arranged between the two storage tanks 2121, and the two feed ports of the two-position three-way valve 2123 are respectively connected to the storage tanks 2121 at the left and right ends, and the discharge port of the two-position three-way valve 2123 is connected to the discharge pipe 2122, and the two-position three-way valve 2123 is connected to the discharge pipe 2122. The three-way valve 2123 is electrically connected to the controller 13.

In order to realize the opening and closing of the distribution box 212, and control the flow rate of the pH regulator in the distribution box 212, a two-position two-way valve 2124 is further provided between the discharge port of the two-position three-way valve 2123 and the discharge pipe 2122. The two-position two-way valve 2124 is electrically connected to the controller 13.

[0042] like Figure 5As shown, the pollutant concentration monitoring device for the whole process of sewage treatment process provided by Example 1 of the utility model, preferably, in order to increase the discharge amount of the PH regulator, the discharge pipe 2122 is placed horizontally, and liquid outlets 21221 are provided at the left and right ends of the discharge pipe 2122. The top of the discharge pipe 2122 is connected to the discharge port of the two-position three-way valve 2123. The PH regulator in the distribution box 212 can enter the discharge pipe 2122 through the two-position three-way valve 2123, and then be released from the liquid outlets 21221 at the left and right ends of the discharge pipe 2122.

[0043] In addition, in order to allow the pH regulator to mix with the sewage in the sewage treatment tank, the discharge pipe 2122 is immersed in the sewage so that the sewage discharged from the discharge pipe 2122 can contact the bottom sewage to prevent the pH regulator from staying on the top of the sewage treatment tank; a liquid flow channel 21222 is provided inside the discharge pipe 2122, and the liquid flow channel 21222 is connected to the discharge port of the two-position three-way valve 2123, so that the cross-section of the liquid flow channel 21222 gradually decreases as the discharge pipe 2122 extends to both ends, and the liquid flow channel 21222 is connected to the liquid outlet 21221. The internal space of the liquid flow channel 21222 is large, while the liquid outlet 21221 of the pH regulator is small, which can increase the discharge pressure of the pH regulator and facilitate the discharge of the pH regulator in the liquid flow channel 21222 into the sewage underwater; at the same time, a filter is provided at the liquid outlet 21221 to effectively prevent impurities in the sewage from clogging the liquid outlet 21221.

[0044] like Figure 4 and Figure 8As shown, the pollutant concentration monitoring device for the whole process of sewage treatment process provided by Example 1 of the utility model, preferably, in order to better heat the temperature of the sewage, the electric heating component 223 includes a plurality of electric heating plates 2231, a first rotating shaft 2232 and a first motor 2233, the output shaft of the first motor 2233 is fixed to the top of the first rotating shaft 2232, the first rotating shaft 2232 is vertically arranged, the electric heating plate 2231 is fixed to the bottom of the first rotating shaft 2232, the electric heating plate 2231 is vertically arranged, and the first rotating shaft 2232 is rotated by the rotation of the output shaft of the first motor 2233, thereby driving the electric heating plate 2231 fixed on the first rotating shaft 2232 31 rotates, the electric heating plate 2231 heats up when powered on, and contacts with the sewage to generate heat transfer, thereby increasing the temperature of the sewage. At the same time, rotating the electric heating plate 2231 can increase the flow of sewage, so that the surrounding sewage can evenly contact the electric heating plate 2231 and generate heat transfer. All the electric heating plates 2231 are distributed in a circular array around the first rotating shaft 2232. The electric heating plates 2231 are electrically connected to the controller 13. When the sewage temperature is higher than the set range, the controller 13 stops the electric heating plate 2231 from heating, and only makes the first motor 2233 work, rotating the electric heating plate 2231 fixed on the first rotating shaft 2232, accelerating the flow of sewage, thereby accelerating the heat dissipation of sewage.

[0045] like Figures 6-7 As shown, the pollutant concentration monitoring device for the whole process of sewage treatment process provided by Embodiment 1 of the utility model, preferably, after long-term use, the accuracy of the detection data of the water quality detector 12 will be disturbed by sewage, therefore, the monitoring component 1 also includes a cleaning component 14;

[0046] The cleaning assembly 14 includes a baffle 141, a second rotating shaft 142 and a second motor 143; the second motor 143 is arranged outside the connecting tube 11; the second rotating shaft 142 passes through the connecting tube 11 and extends into the connecting tube 11; the output shaft of the second motor 143 is fixed to the top of the second rotating shaft 142; the second rotating shaft 142 is arranged vertically; in order to facilitate the second rotating shaft 142 to rotate in the connecting tube 11, a bearing 144 is arranged between the second rotating shaft 142 and the connecting tube 11, the outer ring of the bearing 144 is fixed to the connecting tube 11, and the inner ring of the bearing 144 forms a clearance fit with the second rotating shaft 142. When the second rotating shaft 142 rotates, it and the inner ring of the bearing 144 can rotate without being affected by the connecting tube 11;

[0047] A downward spiral blade 1421 is provided on the outer wall of the second rotating shaft 142; in order to allow the water quality sensor 12 to be freely retracted and adjusted, a retractable inner cavity 1422 is opened from the bottom to the top of the second rotating shaft 142, and a retractable shaft 1423 is matched in the retractable inner cavity 1422.

When the water quality sensor 12 needs to retract upward, the electromagnet 1424 is energized. At this time, the iron block 1425 at the top of the telescopic shaft 1423 is affected by the electromagnet 1424 and moves upward, and the spring 1426 is compressed. When the water quality sensor 12 needs to extend downward, the electromagnet 1424 is de-energized. At this time, the telescopic shaft 1423 is subjected to the deformation force of the spring 1426, so that the telescopic shaft 1423 is away from the top of the telescopic inner cavity 1422;

[0048] An elastic annular protrusion 1427 is provided on the top of the telescopic shaft 1423 to fix the bottom of the telescopic shaft 1423 to the water quality sensor 12. The water quality sensor 12 is always outside the telescopic inner cavity 1422. In order to ensure that the telescopic shaft 1423 is retracted into the telescopic inner cavity 1422, the cross section of the annular protrusion 1427 is larger than the bottom cross section of the telescopic inner cavity 1422. In order to keep the telescopic shaft 1423 stable when the electromagnet 1424 is powered off, the cross section of the annular protrusion 1427 is smaller than the top cross section of the telescopic inner cavity 1422. When the telescopic shaft 1423 and the telescopic inner cavity 1422 form an interference fit, the annular protrusion 1427 is in close contact with the telescopic inner cavity 1422.

[0049] The enclosure 141 is hollow inside, and the circular cross section of the enclosure 141 gradually decreases from the top to the bottom. The top of the enclosure 141 is fixed to the top inner wall of the connecting pipe 11, and the second rotating shaft 142 is in the enclosure 141. When the water quality sensor 12 detects sewage normally, the water quality sensor 12 is lower than the bottom of the enclosure 141, and the water quality sensor 12 is in contact with the sewage. The enclosure 141 can reduce most of the impact force of the second rotating shaft 142 and the telescopic shaft 1423 caused by the sewage, and maintain the normal use of the second rotating shaft 142 and the telescopic shaft 1423;

[0050] A water inlet conduit 15 is also provided at the top of the connecting pipe 11; the water inlet conduit 15 passes through the connecting pipe 11 and extends into the interior of the connecting pipe 11; the water inlet conduit 15 partially extending into the interior of the connecting pipe 11 is in the enclosure 141; the pipe opening of the water inlet conduit 15 faces the spiral blade 1421;

[0051] In order to clean the water quality sensor 12 fixed at the bottom of the telescopic shaft 1423, the electromagnet 1424 is energized, the iron block 1425 at the top of the telescopic shaft 1423 is affected by the electromagnet 1424 and moves upward, the spring 1426 is compressed, and the water quality sensor 12 at the bottom of the telescopic shaft 1423 is retracted into the enclosure 141; the water inlet conduit 15 draws external water to flush the spiral blade 1421, the second motor 143 controls the second rotating shaft 142 to rotate, and the spiral blade 1421 arranged on the outer wall of the second rotating shaft 142 moves the water inlet conduit 15 to the inner wall of the spiral blade 1421. The water discharged is rotated, and the water flow rotates downward around the inner wall of the enclosure 141. As the circular cross-section of the enclosure 141 gradually decreases from top to bottom, the water quality sensor 12 fixed at the bottom of the telescopic shaft 1423 is easily flushed by the water vortex, and in the process of the water quality sensor 12 being flushed, the enclosure 141 blocks the external sewage to prevent the sewage from contacting the water quality sensor 12, thereby avoiding the flow of sewage from affecting the cleaning process of the water quality sensor 12; after the water quality sensor 12 is cleaned, the accuracy of the pollutant concentration detection result in the sewage can be improved.
