Abstract

Relating to the technical field of wastewater treatment, the invention discloses a PH control device and a wastewater treatment system. The PH control device includes: a regulating fluid container, aregulating pipeline, a reflux pipeline, a PH regulating assembly and a solution reaction tank. The regulating fluid container is communicated with the solution reaction tank through the regulating pipeline, the PH regulating assembly includes a pump component, a control component and a detection component, the pump component and the control component are both disposed at the regulating pipeline, and the control component is close to the solution reaction tank relative to the pump component, one end of the reflux pipeline is communicated with the regulating fluid container, and the other end isconnected to the regulating pipeline, also the connecting point is located between the pump component and the control component, and the reflux pipeline is equipped with a reflux valve. The detectioncomponent is disposed in the solution reaction tank, also is electrically connected to the control component, and is used for detecting the PH information in the solution reaction tank and transmitting the PH information to the control component. The PH control device has the characteristics of reasonable design and convenient use, can realize accurate control of the PH value of wastewater, and avoids the impact of wastewater on the environment.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a pH control device and a wastewater treatment system. Background technique [0002] In the field of semiconductor manufacturing, due to the particularity of the process, wastewater with different pH values ​​is usually produced. If this wastewater is directly discharged to the outside world, it will cause great damage to the environment. Therefore, it is necessary to control the pH of the wastewater before discharge to ensure The discharged wastewater can be as neutral as possible to reduce damage to the environment. [0003] Existing pH control methods before wastewater discharge are often difficult to accurately control the pH value of wastewater, and even over-regulation occurs, which instead affects the final pH value of wastewater, and it is difficult to achieve the effect of adjusting the pH value of wastewater. Contents of the invention [0004] The purpos...
