Embodiment 1

[0047] The multi-loaded silicon-based phosphorus removal agent provided in this example is prepared through the following steps:

[0048] (1) Activate the attapulgite clay dissolved in water under alkaline conditions; specifically, after dissolving the attapulgite clay in water, adjust the pH to 8 with 10% NaOH solution, and activate it for 1 hour under continuous stirring;

[0049] When dissolving the attapulgite clay, in parts by mass, the consumption of attapulgite clay is 10 parts, and the consumption of water is 44 parts;

[0050] (2) Adjust the activated attapulgite clay aqueous solution in step (1) to be acidic, so that iron sulfate is loaded on the attapulgite clay; specifically, adjust the pH of the activated attapulgite clay aqueous solution in step (1) to 2 After that, add ferric sulfate powder and continue to stir for 1h;

[0051] (3) Under heating conditions, polyvinylpyrrolidone is added to the solution system in step (2) to form a stable dispersion system; spec...

Embodiment 2

[0057] The preparation method of the multi-loaded silicon-based phosphorus removal agent provided in this example is the same as in Example 1, except that the activation time in step (1) is adjusted to 2 hours.

[0058] When it is used for precipitating phosphorus in sewage, it is added according to the mass ratio of one ten-thousandth of the water sample in the same way as in the comparative example. The test results show that the supernatant at 2 cm below the liquid surface is clear and colorless, and the total phosphorus content in the water sample after phosphorus removal is 0.91mg / L, so the phosphorus removal efficiency is 90.9%.

Embodiment 3

[0060] The preparation method of the multi-loaded silicon-based phosphorus removal agent provided in this example is the same as in Example 1, except that the activation time in step (1) is adjusted to 3 hours.

[0061] When it is used for precipitating phosphorus in sewage, it is added according to the mass ratio of one ten-thousandth of the water sample in the same way as in the comparative example. The test results show that the supernatant at 2 cm below the liquid surface is clear and colorless, and the total phosphorus content in the water sample after phosphorus removal is 0.98mg / L, so the phosphorus removal efficiency is 90.2%.

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a multiplex load type silicon-based phosphorus removal agent, and a preparation method and application thereof. The phosphorus removal agent is prepared through the operation steps of activating attapulgite clay dissolved in water under the alkaline condition, loading ferric sulfate under the acid condition, adding polyvinylpyrrolidone, loading magnesium sulfate and the like. Primary experiments show that the phosphorus removal agent provided by the invention is applied according to the proportion of ten thousandth of the mass of the sewage for the sewage with the total phosphorus content being less than 10mg / L; the phosphorus removal efficiency can be higher than 95 percent; good application effects are achieved. Compared with a conventional phosphorus removal agent, the multiplex load type silicon-based phosphorus removal agent has the main technical advantages that each ingredient in the multiplex load type silicon phosphorus removal agent achieves the environment-friendly effect; non-toxicity and harmlessness are achieved; the preparation process is simple and convenient; in addition, the consumption is small; the addition is convenient; the storage is stable; the phosphorus removal is thorough; the effect taking speed is high; the technical defects of great addition, high color outlet chromaticity, high PH value requirements and the like of the existing phosphorus removal agent can be well overcome, so that better popularization and application values are realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a multi-loaded silicon-based dephosphorization agent, a preparation method and an application thereof. Background technique [0002] Eutrophication of water body means that nutrients such as phosphorus and nitrogen required by aquatic organisms are affected by natural factors or human activities, and enter rivers, lakes, estuaries and other water bodies in large quantities, resulting in rapid reproduction of plankton (such as various algae, etc.) , the dissolved oxygen in the water body drops significantly, the water quality deteriorates, and then a large number of life forms in the water body die, and the water ecosystem and water functions are inhibited and destroyed. The hazards of eutrophication in water bodies are mainly manifested in the following aspects: [0003] (1) Due to the increase of nutrients, algae grow in large quantities, which rapidly cons...
