Problems solved by technology

Benzene hexachloride has contact killing, fumigating and stomach poisoning effects on insects, among which the γ isomer has the highest insecticidal effect, followed by the α isomer, followed by the δ isomer, and the β isomer has extremely low efficiency
Using the traditional treatment process, that is, the coagulation-sedimentation-filtration process, the effect of removing excessive pesticides is not good, and the effect of using granular activated carbon to filter and adsorb is not ideal.
Although the treatment effects of electrodialysis, nanofiltration membrane and RO membrane (reverse osmosis membrane) are very good, the complex treatment process and expensive investment in equipment limit their application to a considerable extent.

Abstract

The invention discloses a method for preparing a filtering medium which is used for removing pesticides in water and includes the steps as follows: a) raw materials containing ultrahigh molecular weight polyethylene, active carbon, sepiolite powder, zeolite powder and a hole opening agent are mixed, and the step (a) is characterized in that the weight ratio of the ultrahigh molecular weight polyethylene to the active carbon, the sepiolite powder, the zeolite powder and the hole opening agent is equal to 100-300:100-300:50-100:50-100:10-50; b) the obtained mixture obtained in the step a) is compacted, sintered and cooled in a mould. The method for preparing the filtering medium to remove the pesticides in the water is simple with low cost and good performance.

Description

technical field [0001] The invention relates to a filter medium for removing pesticides in water and 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] From a global perspective, water resources in almost all countries have been polluted by pesticides. China is a large agricultural country, which uses more pesticides and suffers more serious pesticide pollution. From the early 1980s to the end of the 1990s, some experts from the M...
