Sewage purifying agent and preparation method thereof

[0015] A sewage purifier, made of the following components in weight (kg): modified attapulgite 95, montmorillonite powder 13, chitosan 6, gypsum powder 4.5, quartz stone powder 5.5, polyethylene glycol 11, Glutinous rice flour 3, poly 3-hydroxybutyrate 9, zinc sulfate 0.2, manganese sulfate 0.1, potassium chloride 02, ferrous sulfate 0.3,

[0016] Among them, the modified attapulgite is prepared by the following method: a. Weigh attapulgite 100, medical stone powder 7, potash feldspar 4, calcium carbonate 2, aluminum oxide powder 7, activated carbon by weight (kg) 9. Sorbitan fatty acid ester 0.2, straw powder 5, silane coupling agent 5, Chinese herbal medicine bactericidal liquid 14; b. Put the weighed attapulgite, medical stone powder and potash feldspar into dilute sulfuric acid and grind into powder , Then add an appropriate amount of sodium hydroxide solution to neutralize the pH to 6, remove it, put it in a heating furnace, and calcine at 300-400°C for 3-4 hours. After natural cooling, add the Chinese herbal medicine sterilization solution to it, fully grind, and then Then put it into the high-speed mixer together with the remaining ingredients such as aluminum oxide powder, nano activated carbon, sorbitan fatty acid ester, straw powder, silane coupling agent, and disperse uniformly at a high speed of 9000-10000 rpm , That is, modified attapulgite soil,

[0017] Among them, the Chinese herbal medicine bactericidal liquid includes the following raw materials (kg) by decoction: mugwort leaf 9, artemisia annua 9, scutellaria 9, pomegranate peel 9, licorice 3, aloe 3, stalactite 2, hollyhock leaf 2, nepeta 2 , Hibiscus bark 3, garlic 9, knotweed 11, ranunculus 9, calamus 11, thyme 9, decocted in water, filtered, added quicklime of 2-3% by weight of the filtrate to the filtrate, and fully stirred to obtain the Chinese herbal medicine sterilization liquid.

[0018] The preparation method of sewage purification agent includes the following steps:

[0019] (1) Weigh each component raw material according to the formula ratio;

[0020] (2) Preparation of modified attapulgite;

[0021] (3) Mix the weighed component materials thoroughly, then add an appropriate amount of alcohol with a concentration of 70-80%, and mix well to form 2-3mm spherical particles.

[0022] The comparison of the effects of the sewage purifying agent of the present invention and the unmodified attapulgite for treating the same kind of papermaking sewage is shown in the following table:

[0023]

[0024] It can be seen from the table that the sewage purification agent of the present invention has significantly improved various indicators of sewage treatment and purification, and it is a relatively ideal sewage purification agent.
