Detailed Description
In order to more clearly and completely describe the technical scheme of the invention, the invention is further described in detail by the specific embodiments, and it should be understood that the specific embodiments described herein are only used for explaining the invention, and are not used for limiting the invention, and various changes can be made within the scope defined by the claims of the invention.
Examples
Examples 1-5 and comparative examples 1-2 were prepared by mixing the raw material components in Table 1.
TABLE 1
Example 1
A water treatment agent comprises the following raw material components in parts by weight:
10 parts of surfactant, 8 parts of acid-base ion buffer, 12 parts of passivator, 1 part of foaming agent and 240 parts of water.
A preparation method of a water treatment agent comprises the following specific steps:
s1, mixing the raw material components in proportion;
s2, stirring and heating to 80-90 ℃;
and S3, cooling to obtain the water treatment agent.
Example 2
A water treatment agent comprises the following raw material components in parts by weight:
8 parts of surfactant, 5 parts of acid-base ion buffer, 10 parts of passivator, 0.5 part of foaming agent and 300 parts of water.
The rest is the same as example 1.
Example 3
A water treatment agent comprises the following raw material components in parts by weight:
1 part of surfactant, 10 parts of acid-base ion buffer, 15 parts of passivator, 1 part of foaming agent and 180 parts of water.
The rest is the same as example 1.
Example 4
And 5 parts of an antifreeze agent, wherein the antifreeze agent is one or more of ethylene glycol, glycerol, isopropanol, polyethylene glycol PEG-200, PEG-400 and PEG-600.
The rest is the same as example 1.
Example 5
10 parts of antifreeze agent, and the rest is the same as example 4.
Comparative example 1
A water treatment agent comprises the following raw material components in parts by weight:
10 parts of surfactant, 8 parts of acid-base ion buffer, 12 parts of passivator, 1 part of foaming agent, 0.5 part of flocculating agent and 240 parts of water.
The flocculant is one or two of PAC and PAM.
The rest is the same as example 1.
Comparative example 2
A water treatment agent comprises the following raw material components in parts by weight:
15 parts of surfactant, 20 parts of acid-base ion buffer, 16 parts of passivator, 2 parts of foaming agent and 280 parts of water.
The rest is the same as example 1.
The water treatment agents provided by the embodiment and the comparative example of the invention are applied to a Tai-gang dynamic wave dust removal system, and the compound formula is adopted to add the drugs into a clean water tank, and the results are shown in Table 2. The scaling thickness of the spraying branch pipe is controlled within 2mm after the spraying branch pipe is operated for 3 months, the effective operation of a filter pressing system is ensured, and the system design function of the original dynamic wave is realized.
TABLE 2
Compared with polypropylene and blue liquid water treatment agents adopted before the dynamic wave system in the embodiment 1, the water treatment agent provided by the invention has greatly improved treatment capacity on particles, and a flocculating agent is not used, so that after the water treatment agent is added, the scaling of a pipeline is reduced, the scaling thickness is not more than 1mm in 30 days, and the thickness of a spraying pipe structure is not more than 2mm in 3 months.
Comparing example 1 with comparative example 4, the addition of the antifreeze agent did not affect the treatment effect of the water treatment agent. As can be seen from comparative example 1, the addition of the flocculant decreases the medium-term water permeability, increasing the concentration of particulate matter and the thickness of the pipe scale. As can be seen from comparative example 2 and examples, comparative example 2 changes the component ratio, and it is apparent that the water treatment effect is poor.
In the using process, compared with the originally adopted polypropylene and blue liquid water treatment agent, the water treatment agent provided by the embodiment of the invention has the advantages that the settling rate of solid matter particles in water is slow, and the water liquid is white, but the final treatment result is not influenced.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
