Embodiment 1

[0050] The content of the agent for removing fluoride in sewage in this embodiment is shown in the table below.

[0051] The medicament content table of table 1 embodiment 1

[0052] Element

[0053] Using the medicaments in the above table, according to the above sewage treatment method, treat the sewage containing 20mg / L fluoride ion in the secondary sedimentation tank, add 4‰ of the water amount, and the fluoride ion content will drop to 1.0mg / L, reaching Sewage discharge standards, and can be used for irrigation and general landscape water.

Embodiment 2

[0055] The content of the agent for removing fluoride in sewage in this embodiment is shown in the table below.

[0056] The medicament content table of table 2 embodiment 2

[0057] Element

[0058] Using the medicaments in the above table, according to the above sewage treatment method, treat the sewage containing 20mg / L fluoride ions in the secondary sedimentation tank, add 4‰ of the water amount, and the fluoride ion content will drop to 0.8mg / L, reaching Sewage discharge standards, and can be used for irrigation and general landscape water.

Embodiment 3

[0060] The content of the agent for removing fluoride in sewage in this embodiment is shown in the table below.

[0061] The medicament content table of table 3 embodiment 3

[0062] Element

[0063] Using the medicaments in the above table, according to the above sewage treatment method, the sewage containing 20mg / L fluoride ions in the secondary sedimentation tank is treated, and 4‰ of the water volume is added, and the fluoride ion content is reduced to 0.5mg / L, reaching Sewage discharge standards, and can be used for irrigation and general landscape water.

Abstract

The invention discloses a medicament for removing fluoride in sewage, a preparation method of the medicament and a sewage treatment method, and belongs to the technical field of sewage treatment. Themedicament is prepared from the following components in percentage by mass: 25-35% of glucose, 4-6% of a flocculant, 1-2% of inorganic acid, 8-10% of metal carbonate, and 47-62% of water. The medicament is liquid, operation is convenient, the mud generation amount is less, and the cost is low. The fluoride removal efficiency is high, after treatment, the fluorine content can be decreased to 1.5 mg / L or below, the obvious effect is achieved in a plurality of local sewage treatment plants, and the medicament is suitable for the various types of sewage treatment plants.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a medicament for removing fluoride in sewage, a preparation method and a sewage treatment method. Background technique [0002] Water is an indispensable resource for human beings. As people's awareness of environmental protection increases and they actively respond to national policies and guidelines, relevant departments pay more and more attention to the treatment and discharge of sewage. Fluoride in sewage mainly comes from the manufacture of fluorine-containing products, coke production, electronic component production, electroplating, glass and silicate production, steel and aluminum manufacturing, metal processing, wood preservation, and pesticide and fertilizer production. [0003] Traditional fluoride-containing wastewater removal methods are calcium salt precipitation, coagulation, adsorption and so on. Among them, the lime and calcium chloride combined precip...
