Problems solved by technology

[0003] The above five types of water treatment agents have certain effects on cleaning pollutants in water, but they are all chemical agents, and chemical agents are highly polluting and expensive, have no recycling value, and are disposable products
Although there is application number 200810018218.4, the patent of publication number CN101279248 discloses a modified palygorskite water purifier and its preparation method. The water purifier is to add a certain amount of silane coupling agent, alkyl Ammonium salt, water, activated carbon powder and sodium hydroxide solution are stirred, dried, and ground into powder; although the product has certain adsorption, decolorization and deodorization capabilities after testing, the effect is not very satisfactory, and after use Cannot be recycled

Embodiment 1

[0028] The present embodiment is mainly made up of the raw material of following mass percentage:

[0029] Palygorskite 60%, activated carbon 15%, aluminum sulfate 10%, fatty acid polyethylene glycol ester 7.5%, silane coupling agent 7.5%.

[0030] The preparation method of this embodiment is:

[0031] (1) Put palygorskite and fatty acid polyethylene glycol ester into a bucket and add water to mix and stir to obtain palygorskite slurry, control the water content of palygorskite slurry to be 15% by mass percentage, and the temperature of water is 70°C , and then dehydrated, dried and pulverized to obtain pure palygorskite, then bake the pure palygorskite at 105°C for 2 hours, add silane coupling agent after baking and send it to the mixer for mixing Stir for 12 minutes. After stirring, take out the mixture of palygorskite and silane coupling agent and bake it for a second time at 105°C for 2 hours, and finally cool it for later use;

[0032] (2) Mix the mixture of palygorskit...

Abstract

The invention belongs to the technical field of purifying agent, in particular to an environment-friendly nanometer purifying agent and a preparation method thereof, and the nanometer purifying agent is prepared from the following raw materials by mass percent: 50-75% of palygorskite, 10-30% of activated carbon, 5-25 % of aluminum sulfate, 5-10% of fatty acid polyethyleneglycol and 5-10% of silane coupling agent. The method comprises the following steps: putting the palygorskite in a bucket and adding dispersing agent polycaprolactone glycol ester and water to prepare the palygorskite pulp; dehydrating, drying and crashing and then baking, adding a silane coupling agent for mixing and stirring after baking, baking again after stirring; mixing the baked palygorskite with activated carbon evenly; adding water and the aluminum sulfate for pelleting; and finally drying to obtain a finished product. The invention has good process effect and low production and manufacturing cost, can achieve the aim of comprehensive treatment of various water resources and improving water circulation, and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and in particular relates to an environment-friendly nano water purifier and a preparation method thereof. Background technique [0002] At present, the water purifiers used in industrial water, domestic water and wastewater treatment in various countries in the world mainly include five categories: scale inhibitors, corrosion inhibitors, bactericides and algicides, inorganic coagulants and organic flocculants. Among them, scale inhibitors include two categories: one is organic phosphonates such as HEDP (hydroxyethylene diphosphonate), EDTMP (ethylenediamine tetramethylene phosphonate) and ATMP (amino trimethylene phosphonate) acid salt), etc., the other is polycarboxylic acid such as PAA (polyacrylic acid) and HPMA (polymaleic anhydride) and other water-soluble polymers, in water-soluble polymers, there is also a branch, that is, phosphorus-containing polymers; Corrosion inhibitors are ...
