This invention discloses a wastewater classification and separation system based on industrial wastewater recycling. The invention relates to the field of industrial wastewater treatment and resource recycling technology. The system includes a wastewater acquisition and pretreatment module, a multi-parameter real-time water quality detection module, a comprehensive pollution classification and determination module, a separation and control module, a classification storage and buffer module, a classification treatment module, a recycling intelligent scheduling module, and a data acquisition and intelligent management module. This invention utilizes a collaborative working mechanism of multi-parameter real-time water quality detection and comprehensive pollution classification and determination. It employs a piecewise linear dimensionless scoring function to uniformly map five water quality indicators to a scoring range of 0–10 and then performs a weighted summation. This achieves multi-dimensional, accurate, and real-time determination of the pollution level of industrial wastewater, overcoming the shortcomings of existing technologies where single-indicator judgments are inaccurate and multi-indicator dimension inconsistencies prevent comprehensive evaluation. The targetedness and effectiveness of wastewater classification and treatment are significantly improved.

The invention discloses an automatic cleaning and maintenance control method and system for water quality monitoring equipment and a medium, and belongs to the field of water quality monitoring. The method comprises the steps that pure water generated by a built-in pure water production assembly of equipment serves as a measurement anchor point, and whether sensors are normal or not is judged on the basis of comparison results of detection numerical values of the sensors in a pure water environment and a preset pure water threshold value; monitoring operation state parameters of the pure water production assembly, and dynamically adjusting and updating the pure water threshold value corresponding to each sensor; when the value of the sensor deviates from the threshold value, first-stage pure water flushing is executed; if not, second-stage maintenance is started according to the sensor type, the optical sensor performs optical path self-cleaning or backwashing, and the electrochemical sensor performs electrode cleaning; and detecting again after maintenance, and locking the sensor and generating a fault alarm if the sensor is still not recovered. Through dynamic threshold configuration, progressive maintenance and sensor adaptive cleaning, the problems of reference drift and deep pollution are solved, the data credibility is improved, and the operation and maintenance cost is reduced.

The utility model provides a weeding device for lily planting, which belongs to the technical field of lily planting and comprises a weeding frame, a grass storage box is fixedly connected to the outer wall of the weeding frame, a ventilation groove is formed in the outer wall of the weeding frame, a gasoline engine is fixedly connected to the top wall of the weeding frame, and a pesticide spraying structure is arranged on the top wall of the weeding frame. Symmetrically distributed handrails are fixedly connected to the top wall of the weeding frame, and the cutting assembly comprises an air collecting cover fixedly connected to the outer wall of the grass storage box. According to the utility model, weeds pre-cut by the grass cutting structure are finely crushed through the arranged cutting assembly, so that the weeds can be more thoroughly treated and prevented from damaging internal structures such as fan blades and the like, meanwhile, the crushed weeds are reduced in size, subsequent collection and centralized treatment are facilitated, the service life of equipment is prolonged, and long-term stable operation of the device is guaranteed.
