preparation example Construction

[0037] In an embodiment of the present invention, the preparation method of the polyacrylic acid-modified rectorite comprises the following steps:

[0038] 1) Add 800-1500 parts by weight of water to 80-120 parts by weight of rectorite, and stir at 30-50° C. for 15-24 hours to obtain a mixed solution;

[0039] 2) Add 1 to 3 parts by weight of dopamine hydrochloride to the mixed solution obtained in step 1), and stir at 40 to 60° C. for 24 to 48 hours to obtain dopamine hydrochloride modified rectorite;

[0040] 3) adding 10-20 parts by weight of polyacrylic acid to the dopamine hydrochloride-modified rectorite obtained in step 2), and stirring at 60-80° C. for 24-48 hours to obtain a semi-finished product of polyacrylic acid-modified rectorite;

[0041] 4) cooling, filtering, and drying the semi-finished polyacrylic acid-modified rectorite obtained in step 3), that is, the obtained polyacrylic acid-modified rectorite.

[0042] In an embodiment of the present invention, the re...

Embodiment 1

[0067] Add 800 g of water to 100 g of rectorite, stir at 30° C. for 15 h to obtain a mixed solution; add 1 g of dopamine hydrochloride to the mixed solution, and stir at 40° C. for 36 h to obtain dopamine hydrochloride modified rectorite; Add 20g of polyacrylic acid to the rectorite modified by dopamine hydrochloride, stir at 70°C for 36h to obtain a semi-finished product of polyacrylic acid modified rectorite; cool, filter and dry the semi-finished product of polyacrylic acid modified rectorite, That is, the obtained polyacrylic acid-modified rectorite.

Embodiment 2

[0069] Add 1200g of water to 120g of rectorite, stir at 40°C for 24h to obtain a mixed solution; add 2g of dopamine hydrochloride to the mixed solution, and stir at 50°C for 24h to obtain dopamine hydrochloride modified rectorite; Add 15g of polyacrylic acid to the dopamine hydrochloride modified rectorite, stir at 80°C for 24h to obtain a semi-finished product of polyacrylic acid modified rectorite; cool, filter and dry the semi-finished product of polyacrylic acid modified rectorite, That is, the obtained polyacrylic acid-modified rectorite.

Abstract

The invention discloses a sewage treatment agent, which comprises the following raw materials in parts by weight: 1-5 parts by weight of microorganisms, 10-40 parts by weight of acidic substances, 25-40 parts by weight of starch and 30-50 parts by weight of pump Stolite; the microorganism is one or both of Rhodococcus erythropolis and Corynebacterium. The sewage treatment agent prepared by using microorganisms, acidic substances, starch, and rectorite in the present invention can produce clear, transparent, colorless and odorless water body, and its various indicators can meet GB18918‑2002 "Urban Sewage Treatment Plant Pollutant Discharge Standard" 》First-class B standard, some of the indicators can reach the first-class A standard, and there is no secondary pollution problem.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent and a preparation method thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet drainage requirements or water quality requirements for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. At present, there are many methods of sewage treatment, such as physical, chemical, biological, etc., but most of the physical methods have problems of poor treatment effect and unstable treatment rate; biological methods are too expensive to be popularized and used; chemical methods are mostly used to Sewage is treated, but the existing sewage treatment agent has the problem of secondary pollution in i...
