A method and system for early warning of sewage filtration based on foreign object detection

Abstract

The invention discloses a sewage filtration early warning method and system based on foreign matter detection. The method includes: performing metal detection according to a first metal collection device to obtain information on the first metal detection object; obtaining the first filter screen of the first filtration device Material information; according to the motor control parameters of the first filter device, the first water inlet speed is obtained; by performing collision reaction detection on the first metal detector information and the first filter material information, the first collision is obtained detecting information; generating a first collision assessment result according to the first water inlet velocity; adjusting the first collision detection information according to the first collision assessment result to obtain second collision detection information; according to the second Collision detection information, to obtain the first warning information. It solves the technical problem in the prior art that effective warning cannot be provided for filter screen protection when there is suspended matter filtering, thereby reducing the filtering quality and efficiency, and increasing the economic benefits of filter screen replacement.

Description

technical field [0001] The invention relates to the field of sewage filtration, in particular to a sewage filtration early warning method and system based on foreign matter detection. Background technique [0002] With the continuous development of the economy, the discharge of sewage has increased, and more and more waters have been polluted, which has caused harm to humans and the environment. Based on the current development of science and technology and hot research on the environment, the pollution of sewage Treatment requirements, in order to improve the quality of discharged water and the degree of purification, sewage filtration is usually used for filtration before sewage discharge. Among them, the function of filtration is mainly to remove suspended or impurities in water, but due to the damage of the filter screen during the filtration process The degree of pollution and pollution is high, making the filter replacement more frequent. [0003] However, in the proc...
