Heavy metal wastewater treatment disinfectant

Abstract

The invention discloses a heavy metal wastewater treatment disinfectant. The heavy metal wastewater treatment disinfectant is prepared from the following raw materials in percentage by weight: 30-50% of barium sulfide, 10-30% of calcium carbonate, 10-30% of calcium hydroxide and 20-30% of ferrous sulfate. According to the heavy metal wastewater treatment disinfectant provided by the invention, the problems that similar existing products are insufficient and the heavy metal wastewater treatment is difficult are solved, the sources of the raw materials are wide, and the costs of the raw materials are low; when the heavy metal wastewater treatment disinfectant is applied to the heavy metal wastewater treatment, the use is convenient, meanwhile, the cost is low, the pollution caused by the heavy metal wastewater can be effectively solved, the discharge water of enterprises is helped to meet a national discharged standard, and the environmental pollution is avoided.

Description

technical field [0001] The invention relates to a heavy metal wastewater treatment agent, which belongs to the field of wastewater treatment. Background technique [0002] Heavy metal wastewater, heavy metal wastewater refers to the 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 copper, cadmium, nickel, mercury, zinc, chromium, 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. [0003] Heavy metals in wastewater generally cannot be decomposed and destroyed, but can only transfer their existing positions and change their physical and chemical forms. Common heavy metal wastewater treatment methods include chemical precipitation, membrane concentration and resin a...
