Description

Water treatment system for nonpoint pollution source

The present invention relates to a non-point source treatment system, and more particularly, by effectively purifying and discharging organic and inorganic pollutants introduced from non-point sources such as roads, bridges, large buildings, and wastewater treatment plants, rivers, rivers, The present invention relates to a non-point source water treatment system that effectively prevents contamination of groundwater, so that it can be safely reused as living water, industrial water, and landscaping water, and is easy to maintain and reduce initial installation and maintenance costs. .

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 various media such as zeolite or activated carbon, and other conventional technologies. Is a technique for forming a layer of media such as sand, activated carbon, zeolite so that rainwater flows through the media from top to bottom or through the media from the bottom to the top.

However, these prior art has a specific gravity of the media is greater than the water, and the media is filled with a fixed type, so that the media layer is clogged due to fine turbidity at the time of rain inflow, as well as there is a lot of difficulty in backwashing the media.

At present, contact materials for treating pollutants used in stormwater treatment devices have been developed in various ways such as ocher, ceramic, wood chip using wood, plastic freely formed and light in specific gravity. In addition, a variety of water treatment devices to which such contact media are applied have 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 such as causing secondary pollution or expensive manufacturing costs.

As a result, in reality, the ocher-ceramic carrier containing activated carbon carrier to remove organic matter and the zeolite to remove inorganic matter from the pollutants dissolved in the primary filtered rainwater are laminated and intermittently aerated to decay and blockage. Dissolved contaminants are removed by going through an upflow filter to prevent water, and gravel or ocher ceramic carriers are stacked again, and aeration pipes are installed in the middle to clean the soil. There is a need for a nonpoint source water treatment system that can remove contaminants from the initial stormwater while passing through soil trenches to remove contaminants from the interior.
