PROBLEM TO BE SOLVED: To provide an air purification type greening apparatus which does not generate oppressive feeling in a greening space while having an air purification function and a greening function, is high in freedom of design selectivity of each greening unit and freedom of aspects of installed place and installation, is easy to be constructed, and is excellent in a watering function.SOLUTION: The air purification type greening apparatus comprises a plurality of greening units 2 disposed separately from each other and shared watering supply means 3 connected to the plurality of greening units 2 and supplying watering to each of the greening units 2. Each of the greening units 2 has a plant growth substrate 4 having air permeability and a unit internal ventilation passage in an outer frame for sending air to be passed to a plant growing face 4a through the plant growth substrate 4. The apparatus is provided with forced air sending means 6 which supplies air to the unit internal ventilation passage.【課題】 大気浄化機能および緑化機能を有しながら、緑化空間に圧迫感を生じさせず、個々の緑化ユニットの意匠選択の自由度、設置場所や設置の態様の自由度が高く、施工も容易であり、灌水の機能にも優れた大気浄化型緑化装置を提供する。【解決手段】 互いに離れて配置される複数の緑化ユニット2と、これら複数の緑化ユニット2に連なって各緑化ユニット2に灌水を供給する共用灌水供給手段3とを備える。各緑化ユニット2は、通気性を有する植物育成基盤4、およびこの植物育成基盤4内を植物育成面4aへ通過させる空気を送るユニット内通気路を外枠内に有する。ユニット内通気路に給気する強制送風手段6を設ける。【選択図】 図1
