specific Embodiment approach 1

[0004] Embodiment 1: The water treatment and decontamination agent of this embodiment is composed of ferrate, silicate polymer, and auxiliary agent, and their percentages by weight are: 0.1% to 50% of ferrate, 0.1% to 0.1% of silicate polymer 35%, auxiliary agent 15-80%. The ferrate is potassium ferrate or sodium ferrate; the silicate polymer can form compounds such as high poly-iron-silicon, high-poly-aluminum-silicon or high-poly-iron-silicon with other substances; The water quality can be one or a mixture of iron sulfate, calcium oxide, calcium hydroxide, phosphate, peroxide, hypochlorite, chlorate, special clay, aluminum sulfate, polyaluminum sulfate. The special clay is one or a mixture of activated montmorillonite, pentonite, attapulgite, zeolite and diatomite. In this embodiment, the dosing position of the agent is at the front end of the coagulation process or at the front end of the filtration process, or at the same time at the front end of the coagulation process a...

specific Embodiment approach 2

[0005] Specific embodiment two: The water treatment decontamination agent of this embodiment is made up of ferrate, silicate polymer, auxiliary agent, and their percentage by weight is: ferrate 5~45%, silicate polymer 0.1~ 30%, adjuvants 25-65%.

specific Embodiment approach 3

[0006] Specific implementation mode three: In this implementation mode, taking the 3 types of surface water bodies as an example, the decontamination agent is formulated to a mass concentration of 0.1-5%, and the controlled dosage is 3-20 mg / L, of which 20% ferrate, silicic acid Salt polymer 20%, auxiliary agent 60%, add it to the water body before coagulation, the turbidity removal rate of the filtered water will increase by 30-50%, and the removal rate of organic pollutants will increase by 30-50%. The dosage is 10-15% less than that of conventional chemicals, and the amount of haloform precursors and haloform formation is greatly reduced.

Abstract

The water pollutant eliminating chemical preparation consists of ferrate, silicate polymer and adjuvant. The water pollutant eliminating chemical preparation contains natural sterilizer and the powerful oxidation property may be utilized to destruct viruses and bacteria, generating less side sterilizing product. The present invention has raised coagulation and filtering effects for eliminating turbid matter, color, algae, bad smell, organic pollutant, mutagenic matter, etc.

Description

Technical field: [0001] The invention relates to a decontamination agent for water treatment. Background technique: [0002] At present, the organic pollution of surface water in China's seven major river basins is generally becoming more and more serious, and the types of pollutants are increasing. Water pollution poses challenges to existing water purification technologies. The data show that the existing purification technology cannot guarantee the safety of drinking water quality. In the process of coagulation and sedimentation, the colloidal particles in the water are difficult to destabilize, the dosage of coagulant is greatly increased, the organic pollutants are difficult to be removed from the water, and the cost of water treatment is greatly increased. In the filtration process, the increase of organic matter in the water will cause the surface of the filter material in the filter to be polluted by organic matter, the surface properties will change, and some or al...
