[0013] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 and attached Figure 2 As shown, a tempering device for high-salt and high-ammonia nitrogen wastewater includes a tempering tank 1, and the four sides of the lower part of the tempering tank 1 are fixedly connected to support legs 2; a discharge valve 3 is fixedly connected to the opening in the middle part of the lower part of the tempering tank 1; a high-salt and high-ammonia nitrogen wastewater inlet pipe 4 is fixedly connected to the opening in the middle and upper part of the front side of the tempering tank 1; an alkaline compound dosing pipe 5 is fixedly connected to the opening in the middle and right side of the upper part of the tempering tank 1; a drive motor 6 is fixedly connected to the upper middle part of the tempering tank 1, and the lower end of the output shaft of the drive motor 6 passes through the upper middle side of the tempering tank 1, wherein the lower end of the output shaft of the drive motor 6 is connected to the stirring rod 7 through a coupling.

[0014] One of the conditioning devices for high-salt and high-ammonia nitrogen wastewater also includes a water absorption pH value detection component 8, and the water absorption pH value detection component 8 is fixedly connected to the upper left opening inside the conditioning tank 1, which is conducive to achieving the effect of water absorption detection and can effectively avoid the problem of the pH meter being immersed in sewage for a long time, thereby effectively slowing down the damage of the pH meter electrode and thus improving the service life of the pH meter.

[0015] In this embodiment, combined with the Figure 3As shown, the water-absorbing pH detection component 8 includes a suction pipe 81, the inner middle part of the suction pipe 81 is integrally connected with a fixed plate 82, and the inner right opening of the fixed plate 82 is sealed and fixedly connected with a pH sensor 83, wherein the upper left opening of the upper part of the fixed plate 82 is integrally connected with an air suction pipe 84; the upper end of the air suction pipe 84 extends to the upper side of the suction pipe 81; the upper end of the air suction pipe 84 is fixedly connected with a three-way valve 85, and the upper end pipeline of the three-way valve 85 is connected to a vacuum pump 86.

[0016] In this embodiment, specifically, the upper side of the outer wall of the suction pipe 81 is fixedly connected to the upper left opening of the interior of the conditioning tank 1 .

[0017] In this embodiment, specifically, the vacuum pump 86 is fixedly connected to the upper left rear side of the conditioning tank 1 .

[0018] In this embodiment, specifically, the material suction pipe 81 and the air suction pipe 84 are both made of stainless steel pipes.

[0019] In this embodiment, specifically, the fixing plate 82 is made of a stainless steel plate that is compatible with the interior of the suction pipe 81 .

[0020] In this embodiment, specifically, the discharge valve 3 and the three-way valve 85 are both solenoid valves.

[0021] In this embodiment, specifically, the driving motor 6, pH sensor 83, vacuum pump 86, discharge valve 3 and three-way valve 85 are electrically connected to an external control panel respectively.

[0022] When high-salt, high-ammonia-nitrogen wastewater is injected into the conditioning tank 1, the high-salt, high-ammonia-nitrogen wastewater will submerge the lower end of the suction pipe 81. Then the operator can control the vacuum pump 86 to start through the external control panel, and at the same time control the three-way valve 85 to connect the vacuum pump 86 and the suction pipe 84. At this time, the vacuum pump 86 will suck the air from the lower side of the suction pipe 81 through the pipeline, the three-way valve 85 and the suction pipe 84, and the lower side of the suction pipe 81 will generate negative pressure. Then the high-salt, high-ammonia-nitrogen wastewater in the conditioning tank 1 will move upward inside the suction pipe 81. When the high-salt, high-ammonia-nitrogen wastewater comes into contact with the pH sensor 83, the pH sensor 83 will send a signal to the control surface. The board transmits the pH value data of high-salt and high-ammonia nitrogen wastewater, and the control panel will automatically turn off the vacuum pump 86 and the three-way valve 85 at the same time. The control panel will then display the pH value. When the pH value stabilizes, the control panel will automatically control the three-way valve 85 to connect the external air and the suction pipe 84. At this time, the external air will enter the suction pipe 81, and the high-salt and high-ammonia nitrogen wastewater in the suction pipe 81 will drop and separate from the pH sensor 83, thereby avoiding the problem of the pH sensor 83 being immersed in the wastewater for a long time, thereby effectively slowing down the damage to the pH meter electrode, thereby increasing the service life of the pH meter and achieving the effect of water absorption detection. During use, the operator can install an air filter at the left end of the three-way valve 85 to prevent external impurities from entering the wastewater.
