Nature is destroyed by disordered development of cities and farmland. The land deprived of vegetable causes soil loss and degradation. And, the muddy water generated from that land brings about secondary environmental destruction such as water pollution in the downstream basin. This paper examines the treatment effects of artificial filter materials and water purification materials on the improvement of the muddy water generated from land development activities. Suspended solids can be removed fairly well by combining artificial filters in various modes. However, the clogged conditions of gaps become a trouble to artificial filter materials. It has been proved that combinations of water purification materials and artificial filter materials have sufficient treatment effects on the purification of muddy water. Furthermore, it is considered that muddy water can be treated more effectively by combining these materials with existing facilities such as a settling basin.It was experimented and was examined using the PAC of water purification medicine. The aggregation is promoted the paddy soil by using soil conditioner. And, the soil aggregate destruction by the impulsive force of the raindrop is prevented by the increase of the undrained shear strength of soil. However, there is no rise of the effect, when it is not more effective, as it is done, if the soil conditioner does this concentration thick, and when any fixed concentration is exceeded. Permeability of the soil, improvement of the drainage, improvement on the harrowing can expect that the PAC is added to the paddy soil. In addition, soil aggregate increases on the soil loss by run-off, and it is reduced by the development of the granular structure. In actual field, it is necessary to carry out whether it can expect the effect of the PAC how much and further examination.

大自然被城市和农田的发展障碍摧毁。被剥夺蔬菜的土地会导致土壤流失和降解。而且，从该土地产生的泥泞水会带来二次环境破坏，例如下游盆地的水污染。本文研究了人造过滤器材料和净净化材料对改善土地开发活动产生的泥泞水的治疗效果。通过以各种模式组合人造过滤器，可以很好地去除悬浮固体。但是，间隙的堵塞条件成为人造滤清器材料的麻烦。已经证明，净水材料和人造过滤材料的组合对泥泞的水的纯化具有足够的治疗作用。此外，认为可以通过将这些材料与现有设施（例如沉降盆地）相结合，可以更有效地处理泥泞的水。通过使用土壤调节剂来促进聚集。并且，通过雨滴的冲动力破坏了土壤的土壤骨料，这是由于土壤的未排水剪切强度的提高而阻止的。但是，如果效果不再有效，那么如果土壤调节剂将其浓度厚，并且当超过任何固定浓度时，则不会有上升的效果。土壤的渗透性，排水的改善，痛苦的改善可以期望将PAC添加到稻田中。此外，土壤骨料会因径流而增加土壤损失，并通过颗粒结构的发展减少。在实际领域，有必要执行是否可以期望PAC的影响和进一步检查。
