The invention provides an intelligent dosing system for sewage treatment equipped with a chip protection circuit, which can improve the use effect and intelligence of the product, eliminate the need for frequent manual operations, reduce the loss of human resources, and further improve the sewage treatment effect of the enterprise .

Description

technical field [0001] The invention belongs to the field of sewage treatment, and specifically refers to an intelligent dosing system for sewage treatment provided with a chip protection circuit. Background technique [0002] With the development of society and the deterioration of the environment, environmental protection has reached the point of no delay. In order to reduce the impact on the environment, today's enterprises will set up matching sewage treatment tanks to treat the sewage generated in the production process. In the process of sewage treatment, it is necessary to frequently add chemicals to the sewage treatment tank to improve the effect and efficiency of sewage treatment. In order to reduce the difficulty of adding medicine, most enterprises choose to use the medicine adding device to realize it. Pumped into the sewage treatment tank. However, the dosing mode of the existing dosing device is relatively simple, and its intelligence is poor. In actual use,...

Problems solved by technology

However, the dosing mode of the existing dosing device is relatively simple, and its intelligence is poor. In actual use, it is necessary to pre-set the dosing amount and the adding interval time, and it will work strictly according to the preset dosing amount and dosing time. Working at intervals, it is impossible to adjust the amount and time of adding chemicals according to the specific sewage conditions. When it is necessary to adjust the amount and time of adding chemicals, the operator needs to adjust the equipment on site. Adjust the equipment 5-7 times a day, which greatly wastes human resources
