Environment-friendly heavy metal sewage treatment agent

Abstract

The invention discloses an environment-friendly heavy metal sewage treatment agent. The agent comprises the following raw materials in parts by weight: 10-20 parts of green manure, 2-8 parts of kaolin, 5-10 parts of rectorite powder, 5-8 parts of natural quartz sand, 2-5 parts of sepiolite powder, 4-10 parts of algae powder, 10-20 parts of glass beads, 5-10 parts of gamma-aluminum oxide, 5-10 parts of activated clay, 5-10 parts of peanut straws, 1-5 parts of mulberry roots, 5-10 parts of chitosan, 5-10 parts of lemon peels, 80-200 parts of ethanol and 6-9 parts of chloris virgata. The heavy metal sewage treatment agent realizes a good removal effect on multiple metal ions in the heavy metal sewage and is convenient to use, the production cost is low, and the product is nontoxic and causes no influence on operators; the heavy metal sewage treatment agent can reach the national sewage discharge standard and brings remarkable economic benefits; and the water quality is relatively good after repeated treatment, and the using needs can be met relatively well.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to an environment-friendly heavy metal sewage treatment agent. 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 first reform the production process, use no or less toxic heavy metals, and use chemical precipitation and ion exchange methods to tr...

Problems solved by technology

At present, the treatment of heavy metal sewage is mainly through the method of adding sewage treatment agents to the sewage. The existing sewage treatment agents usually contain most chemical reagents. Although they have certain effects, these chemical reagents will also cause pollution to the treated sewage Certain impact, and the water quality of recycled water after multiple treatments is poor, which cannot meet the needs of use
