Problems solved by technology

[0009] The technical problem mainly solved by the present invention is aimed at the defect that the adsorption of ordinary activated carbon filter elements is easy to reach saturation, and the adsorption capacity will decrease with the use time, resulting in uneven water quality, loss of adsorption function after a short period of use, and frequent replacement. Provided is a method for preparing a self-regenerating activated carbon filter element

Embodiment Construction

[0026] Mix tea tree mushroom, soybean, and pineapple at a mass ratio of 5:2:7, then pulverize them with a tissue grinder for 20-30 minutes to obtain a mixed pulverized product, and mix the mixed pulverized product with protease and water at a mass ratio of 10:1:100 Then put it into an enzymolysis tank, perform enzymolysis at 25-28°C for 6-8 hours, filter and separate to obtain the enzymolysis filtrate; weigh the coconut shell and put it into a pulverizer to pulverize for 2-3 hours to obtain pulverized granules, and mix the pulverized granules with the above The enzymolysis filtrate is mixed in the mass ratio of 1:3 and then packed into the fermenter as the fermentation substrate, then the river bottom sludge with 5% of the fermentation substrate mass is added to the fermenter, stirred evenly with a stirring rod, and the mouth of the tank is sealed. Sealed fermentation at 30-40°C for 3-5 days; after the fermentation is completed, filter and separate to obtain the fermentation re...

Abstract

The invention relates to a preparation method of a self-reproducing activated carbon filter element and belongs to the technical field of preparation of water purifying materials. An enzymolysis filtrate and crushed coconut shells are blended and fermented, a reaction filter cake is carbonized and then is mixed with potassium thiocyanate and amino trimethyl phosphonic acid for a reaction, finally,a product is mixed with polyethylene for membrane casting and firing, and the self-reproducing activated carbon filter element is obtained. Firstly, an enzymatic hydrolysate containing rich amino acid is obtained through enzymolysis, the enzymatic hydrolysate and the crushed porous coconut shell particles are mixed and sealed to be fermented under the action of rich microorganisms, then, coconutshells containing carboxyl and amino groups and an iron salt solution are mixed for a reaction, activated carbon is obtained, the activated carbon, potassium thiocyanate and amino trimethyl phosphonicacid are blended, part of metal ions in the activated carbon are removed, the oxidability of the prepared activated carbon is greatly improved due to holes, the activated carbon and water react to produce hydroxyl free radicals .OH with very high oxidability, the self-reproducing purpose is finally achieved, and the activated carbon filter element has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of a self-regenerating activated carbon filter element, belonging to the technical field of water purification material preparation. Background technique [0002] With the improvement of people's living standards, the requirements for water quality are also gradually increasing. The quality of drinking water is closely related to human health. However, severe environmental damage and pollution have changed the water quality, which in turn affects human health, resulting in a series of vicious circles that seriously affect social progress and human health. [0003] The filter medium refers to any porous material that allows the working medium to pass through and intercepts solid particles or liquid droplets in it to achieve the purpose of separation or purification. At present, most of the filter elements used in the water purification industry can be divided into three different functions: [0004] (1) Fi...
