preparation example Construction

[0045] In an embodiment of the present invention, the preparation method of the polyacrylic acid-modified rectorite comprises the following steps:

[0046] 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;

[0047] 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;

[0048] 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;

[0049] 4) cooling, filtering, and drying the semi-finished polyacrylic acid-modified rectorite obtained in step 3), that is, the obtained polyacrylic acid-modified rectorite.

[0050] The purpose of modifying the rectorite with dopam...

Embodiment 1

[0072] Add 800g of water to 120g of rectorite, stir at 30°C for 15h to obtain a mixed solution; add 1g of dopamine hydrochloride to the mixed solution, and stir at 40°C for 48h to obtain dopamine hydrochloride modified rectorite; Add 20g of polyacrylic acid to the rectorite modified by dopamine hydrochloride, and stir at 80°C for 24h to obtain a semi-finished product of polyacrylic acid modified rectorite; the semi-finished product of polyacrylic acid modified rectorite is cooled, filtered, and dried. That is, the obtained polyacrylic acid-modified rectorite.

[0073] Mix 5 parts by weight of Rhodococcus erythropolis and 10 parts by weight of acetic acid, then add 80 parts by weight of water, and keep warm for 3 hours at 60°C to obtain the first material; add 40 parts by weight of Potato starch was stirred at 50°C for 3h to obtain a second material; then 50 parts by weight of polyacrylic acid-modified rectorite was added to the second material, and stirred at 60°C for 4h to ob...

Embodiment 2

[0075] Add 1500g of water to 80g of rectorite, stir at 50°C for 24h to obtain a mixed solution; add 3g of dopamine hydrochloride to the mixed solution, and stir at 60°C for 24h to obtain dopamine hydrochloride modified rectorite; Add 10g of polyacrylic acid to the rectorite modified by dopamine hydrochloride, stir at 60°C for 48h 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.

[0076] Mix 1 part by weight of Rhodococcus erythropolis and 40 parts by weight of acetic acid, then add 75 parts by weight of water, and keep warm at 65°C for 2 hours to obtain the first material; add 25 parts by weight of Potato starch was stirred at 55°C for 4h to obtain a second material; then 30 parts by weight of polyacrylic acid-modified rectorite was added to the second material, and stirred at 70°C for 3h to obtain a semi-fin...

Abstract

The invention discloses a sewage treatment method, comprising the following steps: sending sewage into a sedimentation tank for preliminary precipitation, recycling the obtained upper layer of sewage into a reaction pool, sending the lower layer of sediment into a sewage tank, and adding sewage treatment into the reaction pool The agent is stirred and left still in the reaction tank by the mechanical arm, and the upper sewage obtained after standing is sent to the purification tank through the osmosis device, and the remaining substances are sent to the sewage tank; the porous adsorbent is added to the purification tank, and through the mechanical arm Stir and stand still in the purification tank, send the upper layer of sewage into the clear water tank, and the lower layer of sewage into the sewage tank, filter the sewage in the sewage tank, and send the obtained sediment into the filter press for pressure filtration After treatment, the obtained sewage is sent to the reaction tank. The present invention improves the purification effect of sewage by adopting the above-mentioned technical scheme, and the treated water body is clear, transparent, colorless and odorless, and its various indexes can meet the first-class B standard of sewage discharge.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment method. 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. But the speed of construction is far behind the needs of pollution prevention and control. At present, my country's sewage treatment mainly adopts aerobic biological membrane treatment technology, that is, AAOM process, but the process is complicated and the purification efficiency is low, which makes my country's sewage treatment industry difficult. Contents of the invention [0003] In view of this, the object of the present inve...
