Problems solved by technology

However, during the extraction process, if the deodorized distillate residue and the organic and inorganic chemical substances produced are directly discharged, they will pollute the environment. At present, there is no effective targeted treatment method. The existing technologies and medicaments are relatively broad and not specific. Sexual treatment, so a substance for targeted sewage treatment is required

Embodiment 1

[0034] Preparation of raw materials:

[0035] Algae dry actives: adopt cyanobacteria actives, which are taken from cyanobacteria polluted areas or areas where algae grow wildly. After salvage and drain, they are sun-dried and inactivated. They are accumulated and matured to make living cells lose their fecundity. Add the accumulated and matured algae The total mass is 1%-5% aluminum potassium sulfate and calcium oxide, wherein the mass ratio of aluminum potassium sulfate and calcium oxide is 1:1. Finally, after drying to a moisture content of 5%-12%, the active dried algae can be obtained.

[0036] The above stacking and aging process is as follows: the salvaged and drained algae are piled up into a conical shape under normal temperature and pressure conditions. The stacking height of the conical shape is not less than 0.8 meters. The piled surface 1-5cm piles up the material, and the remaining material is dried to a moisture content of 5%-12%.

[0037] Zeolite: The general ...

Embodiment 2

[0050] Preparation of raw materials: The raw materials in this example are the same as those in Example 1, except that the algae active dry matter is made of algae dried active matter, and is prepared by the following preparation method: take materials from areas where algae grow wildly, salvage and drain them, and then dry them in the sun Dry inactivation treatment, accumulate and mature them to make the living cells lose their fecundity, add potassium aluminum sulfate and sodium alginate accounting for 1%-5% of the total mass of algae after accumulation and ripening, and the mass ratio of potassium aluminum sulfate and sodium alginate It is 3:1. Finally, it is dried until the water content is 8-10% to obtain the algae active dry product.

[0051] The above stacking and aging process is as follows: the salvaged and drained algae are piled up into a conical shape under normal temperature and pressure conditions. The stacking height of the conical shape is not less than 0.8 me...

Embodiment 3

[0063] Preparation of raw materials: the raw materials in this example are the same as in Example 1, except that the algae drying actives are a mixture of cyanobacteria actives and algae drying actives. The preparation method of the algae dried active substance is the same as that in Example 2. Wherein the blue-green algae active substance is prepared by the following preparation method: water bloom blue-green algae are sieved, and after removing large particles of impurities, adding aluminum potassium sulfate and calcium oxide accounting for 1% to 5% of the total mass of the filtrate, and adding aluminum potassium sulfate and calcium oxide to the filtrate The mass ratio is 2:1, stir evenly, and perform centrifugal dehydration to obtain algae mud with a water content of 86-90%. The algae mud is further dehydrated through a filter press to obtain an algae cake with a water content of 75-80%. The cake is piled up and matured to make the living cells lose their fecundity, and the...

Abstract

The invention discloses a biologically active flocculating agent for treating waste water generated in production of vitamin E. The flocculating agent is prepared by the following raw materials by weight: a zeolite carrier 40% to 60%, dried active substances of algae 8% to 30%, calcium hydrate 2% to 10%, phytic acid 0.5% to 3%, aluminum sulfate 1% to 5%, active carbon 2% to 10%, an active material of a high-molecular resin 1% to 7% and diluent of potassium permanganate with a concentration of 1:3000 0.1% to 4%. A preparation method for the flocculating agent is as follows: a desired amount of zeolite is taken and crushed into particles with a fineness of 10 to 80 meshes; a desired amount of dried active substances of algae are taken and crushed into particles with a fineness of 60 to 100 meshes; a desired amount of industrial calcium hydrate is taken and crushed into particles with a fineness of 30 to 60 meshes; a desired amount of active carbon is taken and crushed into particles with a fineness of 60 to 100 meshes; a desired amount of the active material of the high-molecular resin is taken and crushed into particles with a fineness of 30 to 60 meshes; and a desired amount of phytic acid and potassium permanganate (1:3000) are taken; the solids and liquid are uniform mixed; the biologically active flocculating agent is obtained when water content in an obtained solid-liquid mixture is 5 to 10% according to determination. The biologically active flocculating agent provided in the invention has the advantages of high efficiency, cheapness and strong pertinency.

Description

technical field [0001] The invention relates to a waste water treatment agent. Background technique [0002] Vitamin E (Vitamin E) is a fat-soluble vitamin, also known as tocopherol, is one of the most important antioxidants. Soluble in organic solvents such as fat and ethanol, insoluble in water, stable to heat and acid, unstable to alkali, sensitive to oxygen, not sensitive to heat, but the activity of vitamin E is significantly reduced when fried. Vitamin E is widely used and can promote the secretion of sex hormones. Recently, it has also been found that vitamin E can inhibit the lipid peroxide reaction in the lens of the eye, dilate peripheral blood vessels, improve blood circulation, and prevent the occurrence and development of myopia. Therefore, it has a good development trend in recent years. [0003] Wastewater from natural vitamin E production is mainly discharged from the deodorized distillate (containing vitamin E≥6%), methanol, ethanol, acetone, sodium methoxi...
