Embodiment 1

[0059] A kind of green environmental protection type water treatment agent, comprises the raw material preparation of following parts by weight:

[0060] 40 parts of polyacrylamide, 20 parts of polyferric sulfate, 3 parts of ferrous sulfate, 7 parts of polyaluminum chloride, 25 parts of porous ceramic powder, 20 parts of adsorption gel, and 85 parts of water.

[0061] The preparation method of the porous ceramic powder is as follows: attapulgite, talcum powder, bauxite, andalusite, and alumina are mixed in a mass ratio of 6:4:2:1:1, and then passed through a pulverizer to grind powder. 200-mesh sieve to obtain powder, dry the powder at 55°C for 24 hours, heat up to 1000°C at a rate of 5°C / min, calcinate at 1000°C for 1 hour, and then heat up to 1300°C at a rate of 3°C / min. Calcined at 1300° C. for 3 hours, cooled naturally to room temperature, and air-jet milled to obtain porous ceramic powder with a D97 particle size of 50 microns. The preparation method of the adsorption ge...

Embodiment 2

[0064] A kind of green environmental protection type water treatment agent, comprises the raw material preparation of following parts by weight:

[0065] 40 parts of polyacrylamide, 20 parts of polyferric sulfate, 3 parts of ferrous sulfate, 7 parts of polyaluminum chloride, 25 parts of modified porous ceramic powder, 20 parts of adsorption gel, and 85 parts of water.

[0066] The preparation method of the modified porous ceramic powder is as follows: mix attapulgite, talcum powder, bauxite, andalusite, alumina, and a modifier in a mass ratio of 6:4:2:1:1:0.01, After being ground by a pulverizer, pass through a 200-mesh sieve to obtain a powder. Dry the powder at 55°C for 24 hours, raise the temperature to 1000°C at a rate of 5°C / min, calcinate at 1000°C for 1 hour, and then heat it at 3°C / min. The temperature was raised to 1300°C at a rate of 1300°C, calcined at 1300°C for 3 hours, cooled to room temperature naturally, and then airflow pulverized to obtain a modified porous c...

Embodiment 3

[0069] Substantially the same as Example 2, the difference is only that in this Example 3: the modifying agent is the mixture of calcium carbonate, zinc oxide, magnesium acetate tetrahydrate, the mixture of calcium carbonate, zinc oxide, magnesium acetate tetrahydrate The mass ratio is 1:1:3.

Abstract

The invention discloses a green and environment-friendly water treatment agent and a production process thereof. The green and environment-friendly water treatment agent is prepared by the following raw materials: polyacrylamide, polymeric ferric sulfate, ferrous sulfate, polymeric aluminum chloride, porous ceramic powder, adsorption gel and water. The green and environment-friendly water treatment agent disclosed by the invention is high in purifying efficiency, high in purifying speed, incapable of generating secondary pollution, economical, environmentally friendly and suitable for large-scale production and application. The green and environment-friendly water treatment agent disclosed by the invention can effectively reduce COD, BOD, TN and TP values of domestic sewage and industrialwastewater, effectively promote the adsorption and the precipitation of heavy metal ions and reduce the migration of the heavy metal ions, and has good adsorption and degradation effects on pigment dyes and other organic pollutants and oily wastewater.

Description

technical field [0001] The invention relates to the field of green and environment-friendly water treatment agents. Background technique [0002] The lack of water resources has always been a major problem in our country, especially in recent years with the rapid development of the domestic economy, the water consumption has risen sharply, and the pollution of water resources has become increasingly serious. Industrial water treatment technology is of great significance for saving water resources, reducing water pollution, and prolonging the service life of equipment. Therefore, with the continuous improvement of industrial water treatment and environmental protection requirements, the varieties of water treatment agents in my country are continuously enriched and their performances are continuously improved. There are a wide variety of water treatment agents, from low-molecular to high-molecular, from inorganic to organic, and from single to compound. Composite and other ...
