Environment heavy metal capture agent

Abstract

The invention provides an environment heavy metal capture agent. The environment heavy metal capture agent is prepared from, by weight, 2-5 parts of an organic capture agent, 1-5 parts of an auxiliary, 5-13 parts of an accelerant, 8-16 parts of sodium silicate, 10-14 parts of sodium hydrosulfide, 2-7 parts of trithio-lamictal trisodium, 1-6 parts of a sulfur compound, 8-14 parts of carbon disulfide, 2-3 parts of ethylendiamine, 2-7 parts of sodium tripolyphosphate and 15-58 parts of distilled water. Compared with the prior art, the environment heavy metal capture agent has the advantages that by means of the synergistic effect among the materials, a very high capturing and collecting capability on heavy metal ions is achieved, settling is quick, and solid and liquid separation is quick, easy and convenient after wastewater is treated; the capture agent has powerful chelating force and can be effectively subjected to a chemical reaction with heavy metal to generate insoluble substances, flocculation is thick and large, settling is fast, posttreatment is easy, stability and nontoxicity are achieved, and secondary environment pollution is avoided; the environment heavy metal capture agent can be widely used for treating various kinds of wastewater.

Description

technical field [0001] The invention is an environmental heavy metal scavenger, which belongs to the technical field of sewage treatment. Background technique [0002] With the development of science and technology, the amount of industrial sewage containing heavy metal ions is also increasing, and the pollution of the environment is becoming more and more serious. Sewage containing heavy metal ions mainly comes from mechanical processing, mining, metal smelting, electronics industry and some chemical industries. When the human body ingests excessive heavy metals, the heavy metals will accumulate in the body, causing acute or chronic poisoning. For example, an excess of metallic copper can lead to jaundice, pancreatitis, red blood cell poisoning, esophageal problems, and anemia. Excessive lead can cause kidney disease, neuralgia, leprosy, etc. Excessive arsenic can lead to neuritis, acute poisoning and even death. Excessive cadmium can lead to bone deformation, low back ...

Problems solved by technology

However, these heavy metal scavengers are not thorough enough to remove metal ions, especially Cd2+ and Cr 6+ metal ions cannot be removed at the same time as other heavy metals.
