摘要：
The present invention relates to a tree box filter of low impact development having a pre-treatment filtration facility. The objective of the tree box filter of the present invention is to prevent unfiltered nonpoint pollution source and heavy metals from flowing into a vegetation space part, and to discharge a great quantity of rainwater by being able to prevent blockage of a discharge hole formed in the vegetation space part. 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.본 발명은 전처리 여과시설을 갖는 저영향개발의 수목여과박스에 관한 것으로, 그 목적은 필터링되지 않은 비점오염원과 중금속 등이 식생공간부측으로 유입는 것을 방지할 수 있고, 식생공간부에 형성된 배출공의 막힘되는 것을 방지할 수 있어 다량의 빗물이 배출될 수 있도록 하는 것에 있으며, 이러한 목적은 일측면에는 유입구가 형성되고, 내부는 필터공간부와 식재공간부로 분할되어 구비되는 여과용박스와, 상기 여과용박스의 필터공간부 일면 상부에 일단이 분리 결합가능하게 설치되는 것에 의해 유입구 하부에 위치되어 우수 유입시 이물질을 제거하기 위해 구비되는 스크린망과, 상기 여과용박스의 필터공간부에 삽입되는 것에 의해 상기 스크린망을 기준으로 일측
