Embodiment 1

[0017] A sewage treatment agent for silk dyeing process, comprising the following raw materials in parts by weight: 30 parts of polyaluminum chloride, 30 parts of polyacrylamide, 15 parts of ferric sulfate, 10 parts of modified diatomite, 1 part of composite aluminum-iron flocculant, 1 part of defoamer, 5 parts of absorbent, 10 parts of deionized water.

[0018] The preparation method of the silk dyeing process sewage treatment agent of the present embodiment comprises the following steps:

[0019] (1) In parts by weight, add deionized water into a clean agitator, and add the composite aluminum-iron flocculant under stirring;

[0020] (2) 5 minutes after the composite aluminum-iron flocculant is completely added, add polyaluminum chloride, polyacrylamide and defoamer in sequence under stirring;

[0021] (3) After adding the above raw materials, continue to stir for 20 minutes, then add modified diatomaceous earth, ferric sulfate, and absorbent, and then stir evenly.

Embodiment 2

[0023] A sewage treatment agent for silk dyeing process, comprising the following raw materials in parts by weight: 20 parts of polyaluminum chloride, 20 parts of polyacrylamide, 1 part of ferric sulfate, 1 part of modified diatomite, 10 parts of composite aluminum-iron flocculant, 10 parts of defoamer, 15 parts of absorbent, 40 parts of deionized water.

[0024] The preparation method of the silk dyeing process sewage treatment agent of the present embodiment comprises the following steps:

[0025] (1) In parts by weight, add deionized water into a clean agitator, and add the composite aluminum-iron flocculant under stirring;

[0026] (2) 10 minutes after the composite aluminum-iron flocculant is completely added, add the polyaluminum chloride, polyacrylamide and defoamer in turn under stirring;

[0027] (3) After adding the above raw materials, continue to stir for 40 minutes, then add modified diatomaceous earth, ferric sulfate, and absorbent, and then stir evenly.

Embodiment 3

[0029] A sewage treatment agent for silk dyeing process, comprising the following raw materials in parts by weight: 25 parts of polyaluminium chloride, 25 parts of polyacrylamide, 10 parts of iron sulfate, 5 parts of modified diatomite, 5 parts of composite aluminum-iron flocculant, 5 parts of defoamer, 12 parts of absorbent, 30 parts of deionized water.

[0030] The preparation method of the silk dyeing process sewage treatment agent of the present embodiment comprises the following steps:

[0031] (1) Add deionized water into a clean agitator according to the parts by weight, and add the composite aluminum-iron flocculant under stirring;

[0032] (2) 8 minutes after the composite aluminum-iron flocculant is completely added, add the polyaluminum chloride, polyacrylamide and defoamer in sequence under stirring;

[0033] (3) After adding the above raw materials, continue stirring for 30 minutes, then add modified diatomite, ferric sulfate, and absorbent, and then stir evenly....

Abstract

The invention relates to the technical field of silk industry, and discloses a silk dyeing process wastewater treatment agent and a preparation method thereof. The wastewater treatment agent comprises the following materials in parts by weight: 20-30 parts of polyaluminium chloride, 20-30 parts of polyacrylamide, 1-15 parts of ferric sulfate, 1-10 parts of modified diatomite, 1-10 parts of composite aluminum ferric flocculant, 1-10 parts of defoaming agent, 5-15 parts of absorption agent and 10-40 parts of deionized water. The reaction speed of the preparation method disclosed by the invention is fast, the effect is good, and no secondary pollution is generated during reaction; harmful substances are not used, and polysaccharide used as the flocculant is natural, nontoxic and degradable and has a strong agglomerating function on suspended matters; the preparation method disclosed by the invention is simple and easy to operate, and the materials used for preparing the silk dyeing process wastewater treatment agent are low in price.

Description

technical field [0001] The invention relates to the technical field of silk industry, in particular to a sewage treatment agent for silk dyeing process and a preparation method thereof. Background technique [0002] my country is an ancient country of silk. Chinese silk fabrics have been famous all over the world since Leizu, the concubine of the Yellow Emperor, invented the silk reeling process four thousand years ago. After Zhang Qian went to the Western Regions, the trade of silk products from China began to spread to Europe. They regarded buying and wearing silk as a symbol of wealth and status. The silk reeling equipment has developed from seat reeling, vertical reeling to automatic reeling, but the traditional production process is still used in the silk reeling process, and the process flow is basically the same as the silk reeling process invented by Lei Zu. [0003] With the rapid development of the silk industry, the types and quantities of wastewater have increas...
