Problems solved by technology

In the actual use of the water purifier, there are problems such as incomplete purification of trace organic pollutants, low water efficiency, and slow water discharge.
In addition, the impurities deposited in the existing filter element during the water purification process cannot be cleaned, resulting in frequent replacement and cannot be reused
The used filter element contains a large amount of pollutants, causing secondary pollution to the environment

Embodiment 1

[0028] A filter material for deep purification of drinking water, which is cylindrical in shape, the diameter of the support plate is equal to the diameter of the filter material shell, the upper sieve plate and the lower sieve plate are made of polyurethane, the pore diameter is 10μm, and the thickness of the upper sieve plate is 1cm , the thickness of the lower sieve plate is 1.5cm, and the filling thickness of the amphiphilic polymer adsorption material is 5cm. The water to be purified evenly flows into the amphiphilic polymer material through the upper support plate, fully contacts with it, and eliminates new pollution such as antibiotics. The substance is fully adsorbed and removed, and the purified water is directly transported to the water inlet through the lower support plate. The preparation method of the amphiphilic polymer adsorption material is as follows:

[0029] (1) Preparation of oil phase: Add 2.5g of divinylbenzene, 1g of vinylethylbenzene, and 2.5g of N-vinyl...

The upper sieve plate and the lower sieve plate are both made of polypropylene. 0.5cm, the thickness of the lower sieve plate is 1.5cm, and the filling thickness of the amphiphilic polymer adsorption material is 8cm. The new pollutants are fully adsorbed and removed, and the purified water is directly transported to the water inlet through the lower support plate. The preparation method of the amphiphilic polymer adsorption material is as follows:

[0034] (1) Prepare the oil phase: add 4.7g divinylbenzene, 2g vinylethylbenzene, and 5.1g N-vinylpyrrolidone to 6ml xylene solution containing 0.03g dibenzoyl peroxide, mix well in an ice bath, and A first oil phase, a second oil phase and a third oil phase are obtained.

[0035] (2) Preparation of water phase: Add 0.3 g of emulsifier sodium stearate and 1.0 g...

Embodiment 3

[0038]A filter material for deep purification of drinking water. It is cylindrical. The diameter of the support plate is equal to the diameter of the filter material shell. The upper sieve plate and the lower sieve plate are both made of polypropylene. 0.5cm, the thickness of the lower sieve plate is 2cm, and the filling thickness of the amphiphilic polymer adsorption material is 10cm. Pollutants are fully adsorbed and removed, and the purified water is directly transported to the water inlet through the lower support plate. The preparation method of the amphiphilic polymer adsorption material is as follows:

[0039] (1) Preparation of oil phase: 12.4g of divinylbenzene, 3g of vinylethylbenzene, and 41.5g of N-vinylpyrrolidone were added to 10ml of n-butanol solution containing 0.35g of dimethyl azobisisobutyrate, and placed in an ice bath Mix evenly to obtain the first oil phase, the second oil phase and the third oil phase respectively.

[0040] (2) Preparation of the water...

Abstract

The invention discloses a filter material for deep purification of drinking water, which comprises an upper support layer, a lower support layer and an amphiphilic polymer material filled between them, and the upper support layer and the lower support layer are both porous plates , the average particle size of the amphiphilic polymer material is 5 to 500 microns, and the amphiphilic polymer material in the filter material of the present invention is effective against novel environmental pollution such as antibiotics, endocrine disruptors, disinfection by-products, environmental hormones, and pesticides. The removal rate of pollutants is over 99%.

Description

technical field [0001] The invention relates to a filter material for purifying water, in particular to a filter material capable of deeply purifying new pollutants such as antibiotics, endocrine disruptors, disinfection by-products, environmental hormones, and pesticides in drinking water, belonging to water purification technology field. Background technique [0002] Antibiotics, analgesics, antibacterial drugs, cosmetics and other PPCPs have been detected in rivers, lakes, offshore and other water bodies in recent years, resulting in an increase in the background of PPCPs in the environment and the emergence of drug resistance. Endocrine disruptors, disinfection by-products, environmental hormones, pesticides and other substances and PPCPs are called new environmental pollutants. Most of the new pollutants have good water solubility, strong persistence, bioaccumulation and biotoxicity, causing them to affect the health of aquatic organisms, and then affect human health. ...
