Intelligent wastewater purification system adopting feedback control technology

Abstract

The invention relates to an intelligent wastewater purification system using feedback control technology, which is characterized in that it includes a primary wastewater filtering mechanism, a primary switch control mechanism, a secondary wastewater filtering mechanism, a secondary switch control mechanism and a central control device. The above-mentioned first-level wastewater filtering mechanism and the second-level wastewater filtering mechanism are equipped with detection mechanisms. The intelligent wastewater purification system using feedback control technology monitors the flow of various parts of the system in real time through flow sensors, and then feeds back to the central control device. , by controlling the low-voltage switch and high-voltage switch to ensure that the filtering effect of each filtering mechanism is maximized, thereby improving the filtering effect of the wastewater treatment system; not only that, by adding an optocoupler to the flow monitoring circuit, the circuit is safely isolated, thereby improving In order to ensure the reliability of the system, in the timing control circuit, the type of integrated circuit is NE555. While ensuring accurate timing, it greatly reduces the production cost and improves its market competitiveness.

Description

technical field [0001] The invention relates to an intelligent waste water purification system adopting feedback control technology. Background technique [0002] With the acceleration of modern urban construction, the accompanying pollution problems have become more and more serious, and people have begun to treat polluted wastewater in order to reduce environmental pollution. [0003] In the prior art, the wastewater treatment system uses various filtering mechanisms for filtering, but in the process of filtering, due to insufficient flow control accuracy, it is easy to reduce the filtering effect of each filtering mechanism and reduce the filtering effect of the system; Not only that, in the flow detection circuit, due to the lack of good isolation protection for the circuit, the internal circuit is often damaged due to external interference, thereby reducing the reliability of the system. The current timing control circuit is used Expensive integrated circuits increase ...
