This invention belongs to the field of environmental emergency technology, specifically disclosing a method for analyzing the treatment effect of oily wastewater based on image recognition. It addresses the problems of traditional methods such as infrared and ultraviolet methods for measuring oil content in water, which involve numerous instruments, cumbersome operations, long processing times, and poor adaptability to various scenarios. This invention combines deep learning-based target detection technology with microscopic images of oily wastewater. A target detection model is used to learn and train on the number, volume, and color of emulsified oil droplets in wastewater with different oil contents, treatment processes, and oil types. In field applications, the target detection model is used to identify and calculate the microscopic images of oily wastewater, thereby quickly predicting the oil content. This method is highly operable, accurate, and enables real-time analysis of the treatment effect of oily wastewater, while also being highly adaptable to changes in application scenarios.

The utility model relates to the technical field of water treatment, and discloses a flocculation reaction tank grid bar which comprises a first grid bar plate and a second grid bar plate, the first grid bar plate comprises a first grid bar frame plate, a first lattice bar is installed at the top of the first grid bar frame plate, a first grid plate groove is formed in the first lattice bar, and a second grid plate is installed in the first grid plate groove.
