Problems solved by technology

[0004] However, at present, the heavy metal trapping agent is mainly in the form of powder, which is carried out through feeding and static precipitation. Although this method can adsorb heavy metals, it has problems such as poor adsorption effect and long processing time for low-concentration heavy metal waste liquid. , resulting in a decrease in the overall processing efficiency

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a polymer heavy metal flocculation device. Background technique [0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans, and its water quality and quantity are related to the production process. Heavy metals in wastewater generally cannot be decomposed and destroyed, but can only transfer their existing positions and change their physical and chemical forms. The treatment method is to reform the production process first, and use no or less toxic heavy metals. Chemical precipitation and ion exchange methods ...
