Abstract

The invention discloses an agent for removing phosphorus in sewage. The agent is composed of the following raw materials in parts by weight: 8-14 parts of adina rubella hance, 3-6 parts of gypsum, 2-5 parts of millet bran, 10-25 parts of bauxite, 16-32 parts of coal ash, 10-35 parts of quick lime, 24-40 parts of ferric sulfate, 6-15 parts of activated carbon and 5-12 parts of graphite. The invention also discloses a preparation method of the agent. The raw materials are wide in source, the preparation process is simple, and the production equipment is low in investment cost, so that the agent is suitable for large-scaled industrial production. In the product, adina rubella hance is adopted to adsorb phosphorus. Phosphorus-containing compounds in the sewage are adsorbed by the activated carbon and graphite. The bauxite, ferric sulfate and lime are polymerized to generate a hydroxyl polymeric colloid and a precipitate of hydroxide, so that free phosphorus, organic phosphorus and compounds thereof, hydrogen phosphate, dihydrogen phosphate and the like in the sewage can be adsorbed and associated. The agent is good in treatment effect, does not affect the water quality and has a good social benefit.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a medicament for removing phosphorus in sewage. Background technique [0002] With the rapid development of economy and the acceleration of urbanization process, the problem of water pollution in my country is becoming more and more serious. The massive discharge of industrial wastewater and domestic sewage has become a common pollution problem faced by many cities in our country, seriously affecting the lives of residents, the image of the city and the ecological environment. Phosphorus in industrial wastewater and domestic sewage mainly comes from industrial wastewater such as detergent, feces and phosphating. Its forms include orthophosphate, polyphosphate and organic phosphorus, of which orthophosphate and polyphosphate account for the vast majority, and phosphorus It can be converted between organic phosphorus and inorganic phosphorus, soluble phosphorus and insoluble phosph...
