Embodiment 1

[0040] Calculated on the basis of 1000Kg sewage treatment agent, the formula is as follows:

[0041] Diatomaceous earth 400Kg

[0042] Aluminum sulfate 300Kg

[0043] Sodium Carbonate 290 Kg

[0044] Inorganic polyaluminum ferric sulfate 10 Kg

[0045] The preparation method is as follows:

[0046] (1) First mix the polymeric sulfate and inorganic carbonate;

[0047] (2) Then add inorganic sulfate and mix well;

[0048] (3) Finally, add minerals and mix well.

Embodiment 2

[0050] Calculated on the basis of 1000Kg sewage treatment agent, the formula is as follows:

[0051] Diatomaceous earth 450Kg

[0052] Aluminum sulfate 250Kg

[0053] Sodium Carbonate 280 Kg

[0054] Inorganic polyaluminum ferric sulfate 20 Kg

[0055] The preparation method is the same as in Example 1.

Embodiment 3

[0057] Calculated on the basis of 1000Kg sewage treatment agent, the formula is as follows:

[0058] Diatomaceous earth 500Kg

[0059] Aluminum sulfate 350Kg

[0060] Sodium Carbonate 120 Kg

[0061] Inorganic polyaluminum ferric sulfate 30 Kg

[0062] The preparation method is the same as in Example 1.

Abstract

The invention discloses a sewage treatment agent and application of the sewage treatment agent. The sewage treatment agent comprises the following components in parts by weight: 40 to 55 parts of minerals, 20 to 40 parts of inorganic sulfate, 10 to 30 parts of inorganic carbonate or alkali and 1 to 5 parts of inorganic polymeric sulfate. The product is neutral, and the use of the product does not affect the pH value of an aqueous solution, and further is not affected by the pH value of sewage to be treated, and the sewage treatment agent is convenient to use, and can greatly lower the indexes of total phosphorus, total nitrogen and the like in an eutrophic water body, and the coagulated and settled flocculates are not dissolved in water again because the hydrophilicity is changed to hydrophobicity.

Description

technical field [0001] The invention relates to the field of sewage purification treatment, in particular to a high-efficiency sewage treatment agent and its application. Background technique [0002] In the process of tunnel cleaning, river construction, etc., a large amount of sewage, mud, etc. will inevitably be produced. If the sewage and mud are directly discharged at the construction site, it will cause adverse effects on the environment. In foreign countries, these sewage are usually recovered by tanker trucks and brought back to the city's sewage treatment plants for professional sewage treatment before they can be discharged. Doing this will not only require a lot of time, delay the construction period, but also require a large amount of sewage treatment costs. In the above-mentioned traditional treatment methods, a considerable part of the time is used to transport the sewage to the sewage treatment plant, and the construction efficiency is very low. If you want...
