[0003] At present, in order to improve work efficiency, when steelmaking plants actually process smelting wastewater, they simply filter the smelting industrial wastewater, remove the large solid impurities in the wastewater, and then discharge the wastewater to the outside river. Obviously, this This method cannot remove the impurities in the wastewater very well. After the discharge, the heavy metal impurities in the smelting industrial wastewater will have a certain impact on the environment and the food chain system, so there is still improvement in the treatment of the impurities in the smelting wastewater Space

The invention relates to an energy-saving and environment-friendly treatment method for industrial wastewater containing heavy metals, belongs to the technical field of sewage treatment and purification. Removal equipment for industrial wastewater containing heavy metals is adopted. The equipment comprises an isolation channel used for draining and dredging industrial wastewater, an adsorption device arranged in the isolation channel so as to adsorb and remove impurities in the industrial wastewater, and an impurity removal device used for carrying out further impurity removal operation on theindustrial wastewater subjected to partial impurity removal by the adsorption device. The method has the advantages of convenient operation and good metal impurity removal performance.
Description
technical field [0001] The invention relates to the technical field of sewage treatment and purification, in particular to an energy-saving and environment-friendly treatment method for industrial wastewater containing heavy metals. Background technique [0002] Metal smelting wastewater is the cooling water of ironmaking, steelmaking, steel rolling and other processes and the water for pouring castings and rolling pieces. Since the smelting wastewater contains more smelting impurities such as iron filings, dust and even some heavy metals, in addition , the smelting wastewater also contains certain heavy metals, and the impurities in the smelting industrial wastewater and heavy metal impurities need to be removed before being discharged into the external rivers. Due to the serious environmental pollution in recent years, the treatment of smelting industrial wastewater has become more and more serious. are getting more and more attention. [0003] At present, in order to imp...
