Description

Technical Field

[0002] Chemical laboratory wastewater is very harmful. With the expansion of colleges and universities, the surge in the number of students, the development of the economy, and the progress of scientific research, the amount of chemical laboratory wastewater is increasing. Many laboratories discharge wastewater into the sewer without any treatment. Because the composition of experimental wastewater is quite complex, it contains more toxic and harmful substances such as acids, alkalis, cyanides, hexavalent chromium, arsenides, phenols, benzene, etc. Direct discharge will inevitably cause pollution to people's domestic water and living environment. Therefore, before the laboratory wastewater is discharged, it is often necessary to treat it. At present, in order to treat wastewater of different components separately, common laboratory wastewater treatment equipment generally sets up multiple treatment chambers. In the process of mixing with the treatment liquid, it is necessary to set up multiple driving devices to drive the stirring equipment for mixing treatment, which makes the overall equipment cost high. In addition, common mixing equipment can only achieve simple horizontal stirring, with poor mixing effect and slow mixing speed. In the process of pouring high-concentration chemical wastewater into the equipment, the inner wall of the equipment pipe is easy to adhere to the waste liquid, which is not easy to clean, resulting in long-term corrosion to the inner wall of the pipe, reducing the service life of the device.

[0020] 1. The integrated chemical laboratory wastewater treatment device can adjust the sewage inlet position through the steerable sewage inlet component, so that the treatment tanks at different positions can be matched according to the needs, so as to meet the sewage inlet needs of different positions. After the steerable sewage inlet component corresponds to the treatment tank, the tooth valve and the tooth segment are driven to automatically open the sewage outlet of the sewage inlet pipe, so as to facilitate the direct sewage inlet operation. At the same time, the linkage component and the corresponding first gear are driven, so that the corresponding treatment tank can be automatically opened and connected with the three-way valve, so as to facilitate the subsequent direct wastewater transportation operation.

When the sewage inlet pipe is transferred to the corresponding treatment tank position, the tooth plate and the first gear at the corresponding treatment tank position are driven to open the three-way valve by the first gear, so as to facilitate the water flow operation.

The wastewater is circulated from top to bottom, which not only improves the mixing effect of the wastewater, but also the wastewater circulates through the sewage inlet pipe, and the harmful substances in the wastewater can be detected by the detector. This process can be realized in the mixing process of the wastewater circulation flow, so that the wastewater composition can be monitored in real time, which is convenient for discharge when the wastewater meets the discharge standard, thereby reducing the invalid mixing time.
