Description

Tree filter box

The present invention relates to a tree filter box, and more particularly, to reduce non-point contaminants in rainfall effluents by using a landscaping space in which vegetation is planted, without installing non-point pollutant reduction facilities in a separate space, and treating the same. It relates to a tree filter box that allows water to penetrate underground and contribute to expanding groundwater.

In general, pollutants occurring in urban areas are divided into point pollution sources and nonpoint pollution sources. Point pollutants are pollutants that have specific emission paths such as household sewage and factory wastewater, which can be expressed as a single point, and their movement paths are clear and easy to handle, but nonpoint sources are city, road, farmland, mountain, construction It refers to a discharge source that emits unspecified water pollutants at an unspecified place.

These nonpoint sources are scattered pollutants, unlike point sources that occur continuously at certain points, such as domestic sewage or factory wastewater, and it is difficult to identify the exact outflow path and the inflow is non-persistent. In particular, it is difficult to collect pollutants and their discharge paths are not clearly distinguished, and it is difficult to collect them. Nonpoint pollutants include earth and sand, nutrients (floating substances, nitrogen and phosphorus), bacteria and viruses, oils and greases, heavy metals, organic substances, pesticides and contaminants.

In addition, non-point source was not recognized as the source of pollutant because the outflow of nonpoint source was concentrated only during rainfall and the source was dispersed in a large area. However, the first-flush runoff, where the non-point pollutants flow out at the early stage of rainfall, has a high concentration of non-point pollutants and particularly high concentrations of heavy metals in urban areas. It is required. That is, the outflow of nonpoint pollutants due to rainfall is very irregular, and contains many kinds of nondegradable nonpoint pollutants. In addition, the fluctuations in the amount of generation and load are large. That is, the fluctuation of flow rate over time is large, and the concentration of nonpoint pollutant increases rapidly at the beginning of rainfall.

Therefore, pollutants such as soil, nutrients and high concentrations of heavy metals, which are spilled with rain from nonpoint sources, are difficult to collect and treat, but if they enter the river without special treatment, they contaminate the water quality. The habitat is destroyed and the hydrological system is disturbed.

Conventionally, various kinds of nonpoint pollutant reduction facilities have been developed to reduce such nonpoint pollutants.

Conventional non-point pollutant abatement facilities can be divided into device type and facility type, and these non-point pollutant abatement facilities require separate facility sites, and facility sites with non-point pollutant abatement facilities cannot be used for other purposes. There is a problem that the land use efficiency of the city is lowered.

In addition, due to urbanization, the pavement of a large area has difficulty in expanding the groundwater by preventing rainfall runoff from penetrating into the basement, resulting in the depletion of groundwater.

Accordingly, an object of the present invention is to prevent water pollution and reduce land pollution by reducing nonpoint pollutants in surface water such as rainfall runoff using landscaping spaces where vegetation is planted without installing nonpoint pollutant reduction facilities in a separate space. It is intended to provide a tree filter box that can increase utilization efficiency and infiltrate treated water underground to contribute to the expansion of groundwater.
