Problems solved by technology

Both lead and soluble lead salts are toxic. When 1 kg of human body ingests 5 mg of lead, it may cause acute lead poisoning, resulting in anemia, edema and kidney failure; when lead enters plant roots, bark or leaves, it will affect the growth of plants development

Abstract

A composite for efficient treatment of lead-containing wastewater is prepared from raw materials in parts by weight as follows: 18-24 parts of crop straw powder, 15-26 parts of shell powder, 12-20 parts of tartaric acid, 15-22 parts of polyvinyl chloride resin, 8-14 parts of nano organic montmorillonite, 4-6 parts of potassium hydroxide, 4-5 parts of calcium carbonate, 12-17 parts of hydroxypropyl acrylate, 12-17 parts of hollow glass beads, 4-7 parts of an environment-friendly antimony-based nano-composite fire retardant, 3-6 parts of kaoline, 1-3 parts of ethanol, 7-23 parts of wood fibers (60-80 meshes), 6-10 parts of ferric sulfate, 3-7 parts of gallic acid, 2-4 parts of an initiator and 8-14 parts of PA (polyamide). The composite has the benefits as follows: the composite for efficient treatment of the lead-containing wastewater has a high reaction speed, can thoroughly remove lead, has high lead removal efficiency, moderate cost, high adsorption speed, high adsorption capacity and good selectivity, is non-toxic and harmless and cannot cause harm to human bodies.

Description

technical field [0001] The invention relates to a composite material for efficiently treating waste water containing lead. Background technique [0002] With the rapid development of my country's battery production industry, the waste water produced, especially lead-containing waste water, has caused great pollution to the surrounding water resources of the enterprise. Both lead and soluble lead salts are toxic. When 1 kg of human body ingests 5 mg of lead, it may cause acute lead poisoning, resulting in anemia, edema and kidney failure; when lead enters plant roots, bark or leaves, it will affect the growth of plants development. The heavy metal lead in industrial wastewater belongs to the first class of pollutants, and the country implements strict control when it is discharged. Therefore, how to find an efficient and economical treatment method has become the primary problem to be solved. Contents of the invention [0003] In view of the deficiencies in the prior art,...
