Abstract

The application discloses a groundwater cyanide pollution treatment system and relates to the technical field of groundwater pollution treatment. In the system, a sewage conditioning tank is used for water quality homogenization of underground sewage, and the underground sewage after water quality homogenization is input into a Fenton oxidation device; a multi-agent water inlet device is used for putting multiple agents into the Fenton oxidation device; the Fenton oxidation device is a cyanide pollution treatment site for underground sewage; a multifunctional water quality monitoring system is used for obtaining water quality parameters of water inlet of the Fenton oxidation device; an intelligent online control module is used for taking the water quality parameters of water inlet of the Fenton oxidation device as a feature vector, inputting into a machine learning prediction model, obtaining a predicted putting amount of the multiple agents, and controlling the multi-agent water inlet device based on the predicted putting amount of the multiple agents. The application realizes efficient and stable removal of cyanide by combining real-time monitoring with dynamic dosing and introducing a pollutant concentration-agent putting amount prediction mechanism, and guarantees that the effluent water quality continuously meets the standards.
