Embodiment

[0017] An embodiment of the present invention provides a harmless medicament for sewage treatment, comprising the following composition in parts by weight: 35 parts of bentonite, 10 parts of polyaluminum chloride, 10 parts of conjugated polymer hydrogel, 10 parts of magnetic powder, electret 5 parts of masterbatch, 1 part of carbon nanotube, 15 parts of biochar-based FeS2 composite material, 3 parts of ionic liquid modified chitosan, and 5 parts of CMC / MOF-199 composite pellets.

[0018] Ionic liquid modified chitosan is obtained by modifying chitosan with carboxyl-functionalized ionic liquid 1-carboxybutyl-3-methylimidazolium chloride salt, which has strong anion adsorption performance and can absorb Cr 2 o 7 2－ and PF 6－ After adsorption, it will be precipitated in the sewage.

[0019] The biochar-based FeS2 composite material is synthesized by FeS2 and biochar at a ratio of 1:3 using a hydrothermal method, which can adsorb As in sewage. The larger surface area of ​​bioch...

Abstract

The invention provides a harmless medicament for sewage treatment and a preparation method thereof, and relates to the technical field of sewage treatment. The harmless medicament for sewage treatment is prepared from the following components in parts by weight: 35 to 45 parts of bentonite, 10 to 15 parts of polyaluminum chloride, 10 to 15 parts of conjugated polymer hydrogel, 5 to 10 parts of magnetic powder, 3 to 5 parts of electret master batch, 1 to 3 parts of carbon nano tube, 15 to 25 parts of biochar-based FeS2 composite material, 3 to 5 parts of ionic liquid modified chitosan and 5 to 10 parts of CMC / MOF-199 composite balls. The medicament disclosed by the invention has extremely strong ion adsorbability, can adsorb heavy metal ions in sewage, can also adsorb methylene blue and methyl orange components, also plays a role in reducing COD (Chemical Oxygen Demand), turbidity, ammonia nitrogen and total phosphorus, can quickly deposit along with adsorption after being put into the sewage and form large flocs, and is extremely few in discrete flocs, and very convenient for later cleaning.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a harmless medicament for sewage treatment and a preparation method thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or 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. With the discharge, various heavy metal ions and organic dyes are contained in the sewage treatment. Although the existing sewage flocculants can adsorb heavy metal ions, organic dyes and floating matter, there is a phenomenon of floating after adsorption, and the flocs produced at the same time The degree of aggregation between them is not enough, so it wil...
