Abstract

The composite water pollutant eliminating chemical preparation consists of permanganate, ferrate, silicate polymer and adjuvant. The present invention has the efficient pollutant eliminating and flocculating effects of composite potassium permanganate-ferrate preparation as well as the adsorption, rolling and sweeping effects of inorganic polymer. The composite 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. In addition, the composite water pollutant eliminating chemical preparation has excellent 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...
