The invention discloses an automatic control device and method for industrial wastewater treatment of a thermal power plant. The automatic control device for wastewater treatment comprises a wastewater collection tank, an aeration tower, a drainage pump, a mixer, a neutralizing tank, a clear water tank, a clear water pump and a recovery water tank, wherein the wastewater collection tank, the aeration tower, the drainage pump, the neutralizing tank, the clear water tank, the clear water pump and the recovery water tank are connected in sequence; the mixer is connected with the neutralizing tank; the mixer is further connected with an acid metering pump; a stirrer and a PH meter are connected in the neutralizing tank; and the PH meter and the acid metering pump are connected through a firstmicrocontroller. The PH meter and the turbidimeter are interlocked with the acid metering pump and the clear water pump, and the microcontroller is used for automatically controlling the wastewater treatment process, so that the working efficiency is improved, and medicines are saved; the workload of manual keyboard operation is reduced, and unqualified wastewater is prevented from entering the recovery water tank to be discharged due to human negligence; the device is low in cost, simple in structure and easy to implement, and has important value for industrial wastewater treatment.
Description
technical field [0001] The invention relates to an industrial wastewater treatment device, in particular to an automatic control device and method for thermal power plant industrial wastewater treatment, belonging to the field of environmental protection. Background technique [0002] There are two main types of industrial wastewater from thermal power plants, one is regenerated acid-base wastewater from feed water, and the other is regenerated acid-base wastewater from condensate fine treatment. . Thermal power plants mainly produce alkaline recycled industrial wastewater, and alkaline industrial wastewater not only contains a large amount of alkaline substances, such as sodium hydroxide, sodium bicarbonate, and ammonia water, but also contains a large amount of impurities. If it is directly discharged into the sewage pipe, Discharging into rivers, lakes and seas will cause serious pollution to the environment, and will also cause irreversible damage to nearby crops and dr...
