    • PROBLEM TO BE SOLVED: To provide a water cleaning method and equipment utilizing a planting base plate which is high in a root taking rate and is capable of stably maintaining high cleaning efficiency. SOLUTION: Fine-grained soil 15 which constitutes the planting base plates 10 is placed on a bottom wall 12 pierced with pores 13 through which root systems 17 of plants 26 can pass across middle-grained soil 14 larger than these pores 13. The planting base plate 10 is supported by immersing the bottom wall 12 in the water surface 4 and underwater pollutants are adsorbed and absorbed into the root systems 17 of the plants 16 grown in the water from the pores 13. Preferably a catalyst filter bed 6 for cleaning is arranged in the water below the planting base plate 10 to cause the root systems 17 of the plants 16 grown in the water from the planting base plate 10 to entangle with the filter bed 6. Further, preferably, the catalyst filter bed 6 for cleaning is disposed in the water in a channel-like waterway 2 so as to intersect with the longitudinal direction of the waterway and the planting base plate 10 is disposed on the water surface 4 on the filter bed 6 across the entire width of the waterway.
    • 要解决的问题:提供一种利用种植基板的水分清洗方法和设备,该种植基板具有高的根吸收率并且能够稳定地保持高的清洁效率。 解决方案:构成种植基板10的细粒土15被放置在刺穿有孔13的底壁12上,植物26的根系17可通过其穿过比这些孔13大的中粒土14。种植基 板10通过将底壁12浸入水面4而被支撑,并且水下的污染物被吸附并吸收到从孔13生长在水中的植物16的根系17中。优选地,布置有用于清洁的催化剂过滤床6 在种植基板10的下方的水中,使来自种植基板10的水中生长的植物16的根系17与过滤床6缠结。此外,优选设置用于清洗的催化剂过滤床6 在通道状水路2的水中,与水路的长度方向相交,并且将植入基板10设置在滤床6的水面4上,整个宽度 水路。
