Problems solved by technology

Although traditional filter materials such as polyester cotton (PP cotton), activated carbon, and ceramic filter elements can improve the color and smell of polluted water to a certain extent, they cannot remove the color and smell that may cause the water to be produced. Harmful substances and pollutants in the water, so it can't remove the color and smell in the water very well

Embodiment 1

[0041] Take by weighing 100 grams of medical activated carbon with a particle size of 38 to 250 microns, 190 grams of ultra-high molecular weight polyethylene powder with a molecular weight of 3.5 million (Beijing Dongfang Petrochemical Co., Ltd. Auxiliary No. 20 grams of rod stone powder, 10 grams of 44-124 micron zeolite powder. Put the above four powders into a mechanical stirrer and mix them evenly, then fill them into a tubular mold, press under a hydraulic pressure of 0.6MPa, sinter at 250°C for 150 minutes, cool to 60°C and demould, It can be made into a tubular filter element with many micropores.

Embodiment 2

[0043] Weigh 150 grams of medical activated carbon with a particle size of 178 to 710 microns, 200 grams of ultra-high molecular weight polyethylene powder (Beijing Dongfang Petrochemical Co., Ltd. Auxiliary Plant No. 2, M-III type) with a molecular weight of 3.5 million, and attapulgite powder 40 grams, 25g of 30-420 micron zeolite powder. The above four powders were put into a mechanical stirrer and stirred evenly, and the rest of the manufacturing steps were the same as in Example 1.

Embodiment 3

[0045] Take by weighing 200 grams of medical activated carbon with a particle size of 26 to 250 microns, 250 grams of ultra-high molecular weight polyethylene with a molecular weight of 2.5 million (Beijing Dongfang Petrochemical Co., Ltd. Auxiliary No. 2 Factory, M-II type), acidified attapulgite 30 grams of stone powder, 30 grams of 38-89 micron zeolite powder. The above four powders were put into a mechanical stirrer and stirred evenly, and the rest of the manufacturing steps were the same as in Example 1.

Abstract

The invention relates to a filter medium used for removing the color, the peculiar smell and the colloidal substances in water, as well as the preparation method thereof, a filter core using the filter medium, a water purifier and a drinking water dispenser. The preparation method of the filter medium used for removing the color, the peculiar smell and the colloidal substances in the water comprises the following steps: firstly, raw materials containing active carbon, ultrahigh molecular weight polyethylene and attapulgite powder are mixed, and the step is characterized in that the weight ratio of the active carbon, the ultrahigh molecular weight polyethylene and the attapulgite powder is 50-200:100-300:5-50; secondly, the mixture obtained from the step one is pressed, sintered and cooled in a mold. Using the filter medium can remove the color, the peculiar smell and the colloidal substances in the water, so as to improve the sensory indexes of the drinking water.

Description

technical field [0001] The invention relates to a filter medium for removing color, peculiar smell and colloid of water, a preparation method thereof, a filter element using the filter medium, a water purification device and a water dispenser. Background technique [0002] The rapid development of industry and agriculture has led to serious damage to water resources. Industrial wastewater is discharged into rivers and lakes, pesticides, insecticides, etc. are used in large quantities, and domestic garbage and domestic wastewater are discharged indiscriminately. As a result, many harmful substances are produced in the water. Water pollution has increasingly become a serious problem affecting people's lives. [0003] Color, odor and taste are sensory properties of drinking water. If the water has a color or smell, or contains colloids, it will first cause people's resistance and disgust, so drinkers will often refuse to drink the water. [0004] In national drinking water s...
