Intelligent dosing formula control system and method

Abstract

The invention discloses an intelligent dosing formula control system and method, and the system comprises an information collection module, a data index module, a formula database module, an intelligent formula learning module, and a control output module. The control method comprises the following steps: S1, receiving a water quality signal; S2, converting the water quality signal into a formula index value N, and searching a standard formula index value Nn which is the closest to the formula index value N: enabling a standard formula dosing value KoutN corresponding to Nn to serve as an output value Kout when N is equal to Nn, or else, correcting the standard data in the formula database module; S4, controlling the output of the formula dosing output value Kout. Through intelligent learning, the system and method can correct the standard data in the formula database module, replace a manual dosing experiment and a conventional dosing calculation mode, achieve the precise dosing, save the cost of medicine, and guarantee the stable quality of outgoing water. The system and method achieve an effect that the emission is far lower than the national first-level emission standard.

Description

technical field [0001] The invention belongs to the automatic dosing technology in the technical field of water treatment, and in particular relates to an intelligent dosing formula control system and control method. Background technique [0002] At present, activated sludge treatment processes such as oxidation ditch, CASS, and membrane treatment are widely used in municipal sewage treatment plants and industrial wastewater treatment plants. In order to ensure that the effluent water quality meets the standard, agents such as coagulants are often added to the secondary sedimentation tank or flocculation tank. to realise. The method of adding the dosage is mainly to calculate the dosage according to the experience or manual test ratio, and to add the dosage at regular intervals. Due to the instability of the influent water quality, in order to ensure that the effluent water quality is up to standard, many sewage treatment plants or workshops consider the dosage of chemicals...

AI Technical Summary

Problems solved by technology

Due to the instability of the influent water quality, in order to ensure that the effluent water quality is up to standard, many sewage treatment plants or workshops consider the dosage of chemicals according to the most serious water quality. This method makes the effluent water quality up to standard, but causes a lot of waste of chemicals; The method of calculating the dosage of the medicine by the chemical ratio, the dosage of the medicine can be controlled to a certain extent, but the quality of the effluent water will be good and bad, and the quality of the effluent water can not be guaranteed to meet the discharge standards in real time
