Abstract
The invention provides movable treatment equipment and method for strengthening and removing wastewater containing a plurality of heavy metals. A gradient treatment technology for treating the wastewater containing the plurality of heavy metals such as cadmium, zinc, copper, lead, mercury and arsenic is adopted, that is, treatment is divided into three stages according to heavy metal concentrations in the wastewater, the treatment comprises the following treatment in sequence: high-concentration treatment, namely, heavy metal strong capture and chemical sinking, medium-concentration treatment,namely, flocculation adsorption, and low-concentration treatment, namely, Kaidefei and mixed activated carbon strong adsorption; and treatment is performed until standardized discharge. The method provided by the invention realizes simultaneous standardized discharge of the wastewater containing the plurality of heavy metals, and has no secondary pollution.
Description
technical field [0001] The invention relates to the technical field of heavy metal wastewater treatment, and in particular to a mobile device and method for strengthening the treatment of various heavy metal wastewater. Background technique [0002] Mining, metallurgy, chemical industry, machinery and other industries will produce industrial wastewater containing heavy metals, especially the heavy metal wastewater produced in the production process of mining and metallurgical enterprises. Compared with organic wastewater, heavy metal wastewater has two particularities that make heavy metal pollution difficult to detect. First, unlike organic pollution, heavy metal wastewater has color and odor, so that people can perceive its harm from the senses. Second, heavy metals do not degrade in nature like organic matter and become harmless. To make heavy metals harmless, they can only be separated from wastewater. [0003] Heavy metals are typical inorganic toxic substances. Heavy...
