Abstract

The dosing system fuzzy controller of the invention can well improve the reliability and the stability of a dosing system, and saves water treatment cost to a great extent. The dosing system fuzzy controller comprises a fuzzy controller, a variable-frequency control system, a metering and dosing system, a coagulating sedimentation water treatment system, a flow sensor, a flow transmitter, an incoming water turbidity sensor, an incoming water turbidity transmitter, an outgoing water turbidity sensor, and an outgoing water turbidity transmitter. Incoming water flows in through the flow sensor, the incoming water turbidity sensor and the coagulating sedimentation water treatment system. The output end of the flow sensor is connected with the flow transmitter. The output end of the incoming water turbidity sensor is connected to the incoming water turbidity transmitter. The output ends of the flow transmitter and the incoming water turbidity transmitter are connected with the input end of the fuzzy controller. The fuzzy controller is connected with the variable-frequency control system. The variable-frequency control system is connected with the metering and dosing system. The metering and dosing system is connected with the coagulating sedimentation water treatment system. The output end of the coagulating sedimentation water treatment system is connected with the outgoing water turbidity sensor.

Description

technical field [0001] The invention belongs to the technical field of mine water treatment, and in particular relates to a fuzzy controller of a dosing system. Background technique [0002] In the process of water treatment, coagulation is a very important process link, which is used to remove suspended particles and colloidal substances in water, so as to purify water quality. Mine water is a special kind of industrial wastewater produced in the production process of coal mine enterprises. It mainly contains coal powder and rock powder. Its removal generally adopts the coagulation sedimentation process, and the quality of the coagulation effect directly affects the water treatment system. The effluent water quality and treatment cost, and this effect mainly depends on the optimal dosage of coagulant. However, the coagulation process is a nonlinear, complex system with a large time lag, and it is difficult to describe the process with an accurate mathematical model. Howev...
