Abstract

The invention discloses a formula and a preparation method of a natural mineral heavy-metal sewage treatment agent. The treatment agent is composed of, by weight, 18.5-25% of montmorillonite, 28.5-35% of aluminum sulfate, 13-25% of caustic soda flakes, 10-22.5% of ferric chloride, 8.5-18% of sodium sulfite, and 6.5-12% of calcium hydroxide. With the formula and the preparation method of natural mineral heavy-metal sewage treatment agent, defects of existing products and heavy-metal sewage treatment difficulty are solved. The treatment agent is convenient to use, and production cost is low. With the treatment agent, pollution caused by heavy-metal sewage can be solved from the source, heavy-metal sewage can be cleaned, a national sewage discharge standard can be reached, and no secondary pollution is caused to the nature.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a formula of a natural mineral heavy metal sewage treatment agent and a preparation method thereof. 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. At present, there are many products used in the treatment and purification of heavy metal sewage in China, but the production cost is relatively high, and the technological process of treating and purifying sewage is cumbersome. Contents of the invention [0003] In view of the deficiencies in the above-mentioned technologies, the present invention provides a formula and a preparation method of a natural mineral heavy metal sewage treatment agent with low production cost and simple process flow for treating and p...
