Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a pH regulating device. Background Art

[0002] The pH regulator plays a vital role in the recycling and treatment of phosphorus waste. The recycling and treatment of phosphorus waste needs to be carried out in a specific acid-base environment, and the pH value of the water body is one of the key factors affecting this environment. The pH regulator monitors the pH value of the water body and adjusts it as needed to ensure that the pH of the water body is within the most suitable range. This can provide a good treatment environment that is conducive to the decomposition, transformation and utilization of phosphorus waste. The role of the regulator is not only to simply maintain the stability of the pH value of the water body, but more importantly, it provides a stable and efficient treatment environment for the recycling of phosphorus waste, thereby improving the efficiency and success rate of phosphorus waste recycling.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "wastewater PH regulating device", and its application number is "CN202322007148.5". This patent mainly uses a water storage tank, which has a water inlet and a water outlet, and the water outlet is located at the top. Wastewater enters the water storage tank through the water inlet and flows out from the water outlet; a placement frame is arranged in the water storage tank, which is used to load lime; a turbine arranged at the water outlet and a stirring rod coaxially connected to the turbine are rotated, which acts on the inside of the placement frame.

[0004] However, the lack of a warning light in the device will reduce the operator's ability to promptly perceive the status of the equipment. Once the pH value deviates from the set range, the operator may not be able to detect it in time and take corresponding adjustment measures, thus affecting the stability and efficiency of the water treatment process. Secondly, the lack of a warning light will increase the risk of equipment failure, because the operator cannot use the warning light to promptly detect whether the equipment is working properly, which may cause the equipment to be in an abnormal state for a long time without being dealt with in time, thereby affecting the operation of the entire water treatment system and water quality control.

[0005] To this end, we propose a pH regulating device. Utility Model Content
