The objective is achieved by the tree box filter including: a filter box wherein an inlet is formed at one side and which is divided into a filter space part and the vegetation space part inside; a screen net which is formed to remove foreign substances during rainwater inflow by being located at a lower part of the inlet, while being installed to have one end separably combined with an upper part of one plane of the filter space part of the filter box; a filter part which supplies the rainwater flowed in through the inlet hole to the vegetation space part by filtering the nonpoint pollution source and the heavy metal and calcium chloride included in the rainwater while being installed at one side or the other side or both sides of the screen net by being inserted into the filter space part of the filter box; and a vegetation soil protection filter layer which prevents vegetation soil from being scattered by being filled in a vegetation soil layer and an upper part of the vegetation soil layer so that trees planted in the vegetation space part of the filter box can grow, and also can filter the nonpoint pollution source and the heavy metal included in the rainwater flowing in from a sidewalk.

Description

{Trees filter box of Low Impact Development with pretreatment filtration facility with low impact development with pretreatment filtration facility}

More particularly, the present invention relates to a forest filter box having a low-impact development having a pretreatment filtration facility. More specifically, the present invention relates to a forest filter box having a non- It removes nonpoint pollutants and heavy metals in the rainwater, and stores the filtered rainwater in a rainwater storage tank or infiltrates it into the ground. The stored rainwater is used in the runway of the city center, the fire water supply, the urban fountain, The present invention relates to a tree filter box of low-impact development having a pretreatment filtration facility for preventing disasters.

As is well known, water pollutants are unspecified as unspecified pollution sources in urban areas, irrigation, farmland, mountainous areas, construction sites, and so on. Urban wastewater, industrial wastewater, Are estimated to account for about 30% of the pollutants generated by the Han River (Ministry of Environment).

When these pollutants are treated through sewer pipes, existing facilities become larger than necessary, and it may be difficult to treat unspecified pollutants.

In response to these problems, the Ministry of Environment has been phasing out measures to deal with non-point pollutants in three stages from 2004 to 2020. Currently, several companies use non-point pollution abatement technology to treat non-point pollution.

However, in the nonpoint pollution abatement technology, the nonpoint source pollution source generated by the industrial pollution source such as industrial wastewater is rapidly discharged through the sewage pipe or the excellent pipe which occurs together with the pollution source, and the protection of the water resources has been neglected.

In addition, due to the urban development, the road packing ratio (87.6% of the average packing rate in Seoul, 2008) is high, so it is difficult to penetrate into the soil when it rains and the amount of infiltration is small. .

In other words, the road pavement rate is gradually increasing due to the urban development, and about 30% of the total pollutants generated by it are non-point pollutants. Therefore, existing non-point pollution abatement devices are used for rapid elimination of rainwater runoff and large- The problem is that many problems arising from the concept, such as damage to the natural environment due to the acquisition of large-scale treatment facilities, increased pollution load due to the introduction of unspecified pollutants, increased maintenance costs, By treating them like wastewater, the cost is increased and the treated storm is not sent back to nature but sent to industrial facilities such as storm water pipes and sewer pipes to be sent to rivers and so on. As a result, increase of peak discharge causes secondary flood Damage is occurring.

In consideration of this point, recently a patent application No. 10-2011-0113778 has been filed for a natural circulation type wood flowerpot filtration system.

The natural circulation type wooden flowerpot filtration system includes a wooden box, a filtering filter formed in the wooden box and formed with a lamination space in which a filter medium can be installed inside the box, An inlet space formed in the entrance of the screen net for removing foreign substances and an additional space formed between the wooden box and the filter so as to allow the storm received through the inlet to stay for a predetermined time, A gravel layer capable of increasing the permeability of the vegetation soil and the permeability of the vegetation space, and a gravel layer capable of enhancing the permeability of the gravel layer to discharge the filtered gravel layer through the vegetation layer and the gravel layer, And an excellent discharge pipe installed through the filtering filter and the wooden box.

However, in the conventional natural circulation type wooden flowerpot filtration system constructed as described above, when various contaminants such as tire dust, road dust, and heavy metal in the soot flow into the tub, The surface of the filtration filter is too small to allow the contaminants to be introduced into the vegetation soil without sufficiently filtering the contaminants.

In addition, as described above, the conventional natural circulation type wooden flowerpot filtration system is filled with gravel in the lower part of the vegetation so that the floating substances generated from the contaminants flowing into the vegetation and the suspended matter generated from the vegetation soil The space between the gravel and the gravel is clogged and the amount of discharge through the discharge port or the lower discharge port is extremely small.
