[0029] Example:

[0030] The following is combined with Figure 1 This application is described in further detail.

[0031] The present application discloses a multi-purpose synthetic purifier, which comprises, by weight percentage, the following:

[0032] Ferric chloride 18-50%;

[0033] Polyaluminium ferric chloride 2-37%;

[0034] Calcium chloride dihydrate 10-60%;

[0035] Ferrous sulfate 22-52%;

[0036] Polyaluminium chloride 5-45%;

[0037] Basic aluminum chloride 10-30%.

[0038] A method for using a multi-purpose synthetic purifier, based on the multi-purpose synthetic purifier of claim 1, the method for using comprises the following steps:

[0039] S1. Measure the sewage concentration and make a proportion according to the measured sewage concentration;

[0040] S2, mixing the purifier with water and stirring to fully blend the two;

[0041] S3, adding polyacrylamide to the mixture obtained in step S2 and stirring, and putting it into the wastewater reaction tank after it is fully blended.

[0042] Furthermore, in step S2, an aeration stirring method is used, and the stirring time is 20 minutes.

[0043] Through the above technical solution, it takes 20 minutes for the water and the prepared purifier to fully blend, so as to ensure the best purification effect when used.

[0044] Furthermore, after adding polyacrylamide in step S3, stirring is required for 10 minutes.

[0045] Through the above technical solution, it is ensured that polyacrylamide is fully mixed with the purifier and wastewater to form a uniform solution, providing a basis for the subsequent flocculation reaction.

If the sewage concentration is 50000, the ratio of the synthetic purifier to the sewage is 3.8:6.2.

[0047] The implementation principle of a multi-purpose synthetic purifier and a method of using the present application is as follows:

[0048] Ferric chloride is a covalent inorganic compound that is easily soluble in water and has strong water absorption. It is an oxidant that has a strong oxidizing effect on organic matter. It is acidic and corrosive.

[0049] Calcium chloride dihydrate is a desiccant and dehydrating agent; it can be used as a "snow melting agent". It has strong hygroscopicity and is easily soluble in water.

[0050] Polyaluminium chloride is an inorganic polymer coagulant with fast floc formation and sedimentation speed, and has a decolorization effect on wastewater.

[0051] Polyaluminium ferric chloride has a strong demulsifying effect on emulsified wastewater. It is a highly efficient coagulant with fast flocculation and precipitation. It can reduce the pH value, has low corrosiveness and good light transmittance.

[0052] Ferrous sulfate can quickly remove and precipitate suspended matter in wastewater. Ferrous sulfate is an inorganic substance with reducing properties and is soluble in water and glycerol.

[0053] Basic aluminum chloride can effectively remove color from wastewater.

[0054] The invention has multiple functions such as ion exchange, demulsification, flocculation, adsorption redox and the like; it can quickly remove COD in wastewater, neutralize pH, change hydrophilicity, compress the diffusion layer, increase the counter ion effect, and finally achieve the purpose of redox.

[0055] After adding polyacrylamide, it can effectively adsorb surfactants and various pollutants in the wastewater during the hydrolysis process and polymerize into a colloid, which can quickly precipitate and separate in a short time, thereby purifying the wastewater.

[0056] The beneficial effect is that wastewater can be discharged continuously without pausing, with fast sedimentation or floating speed, small investment and good treatment effect.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
