Sewage filtering early warning method and system based on foreign matter detection

Abstract

The invention discloses a sewage filtering early warning method and a system based on foreign matter detection, and the method comprises the steps: carrying out the metal detection according to a first metal collection device, and obtaining the first metal detection object information; obtaining first filter screen material information of a first filtering device; obtaining a first water inlet speed according to the motor control parameter of the first filtering device; performing collision reaction detection on the first metal detection object information and the first filter screen material information to obtain first collision detection information; generating a first collision evaluation result according to the first water inlet speed; adjusting the first collision detection information according to the first collision evaluation result to obtain second collision detection information; and obtaining first early warning information according to the second collision detection information. The technical problems that in the prior art, when suspended solids are filtered, effective early warning cannot be conducted for filter screen protection, so that the filtering quality and efficiency are reduced, and the economic benefits of filter screen replacement are increased are solved.

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 object 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...
