Description

  Activated carbon-contact media for adsorbing and resolving organic matter and water treatment system for purifying non-point source of contaminant using the same}

  The present invention relates to an activated carbon contact medium for adsorptive decomposition of organic matter, and more particularly, an organic material formed by mixing and molding activated carbon particles and fiber materials such as polyether or polyester that are easy to melt, or by mixing acrylic or epoxy adhesive resins. The present invention relates to an activated carbon contact filter for adsorption decomposition and a water treatment apparatus for non-point pollutant purification using the same.

  Generally, pollutants include point pollutants emitted from well-defined and limited point sources, such as domestic sewage, industrial waste and livestock waste, and agricultural land in unspecified areas, grasslands, forests, construction sites, mines, logging sites, Discharge areas can be divided into nonpoint pollutants emitted from an unspecified and widespread nonpoint source, such as waste disposal sites, landfills, urban areas, roads, and industrial sites.

 Among them, the conventional non-point pollutant treatment technology includes a screen for removing contaminants by installing a partition horizontally and removing contaminants by passing through various media such as anthracite or activated carbon, and other conventional technologies. Furnace has a technology that forms a layer of media such as sand, activated carbon, anthracite so that rainwater flows through the media from top to bottom or through the media from bottom to top.

  However, these prior arts have a specific gravity of the filter medium larger than water, and the filter medium is filled in a fixed manner so that the filter layer is clogged due to fine turbidity at the time of rain.

  Currently, the contact media for treating pollutants used in rainwater treatment devices are made of activated carbon nonwoven fabric having a relatively large surface area and easy to make, loess, ceramic, wood chips made of wood, which are easy to make pores, and plastic freely formed and light in specific gravity. Various contact media have been developed, and a variety of water treatment apparatuses to which such contact media have been applied have also been developed. However, their commonality is to increase the voids that can be attached to the microorganisms to the maximum, to stabilize the growth of the microorganisms and to withstand impact loads such as poor loads or overloads, but they are easily stretched, desorption, or difficult to attach. There is a problem that causes secondary pollution, or expensive manufacturing costs.

  Therefore, in view of these problems, the use of activated carbon, which has a very large pore and specific surface area and does not interfere with the growth of microorganisms, is used instead of the nonwoven fabric for contact media, which has had to adsorb and fix the molding to a few μm so far.
