This study was developed the systems of water purification on waterside civil structures using porous concrete and feeding organisms to realize with little maintenance. An assessment of water purification and durability for water of porous concrete were investigated. Main results were as follows(1) The higher ability of water purification on porous concrete was obtained using proper materials and void characteristic(2) The lowest compressive strength of porous concrete which is stored tow years in the zone of low tide, is around half of initial strength(3) It could be confirmed that there were about same number of kinds of feeding organisms in the water purification testing plant using porous concrete than that of the next concrete seawall constructed over 10 years ago after 2 years(4) The coastal deposit deep bottom of the water purification testing plant using porous concrete was black mud because of low oxygen concentration, on the other hand there was a little coastal deposit on shallow bottom of that plant. It is considered that there were many Bivaivia on the shallow bottom and Binvaivia had eaten the coastal deposit(5) From above results, it is obtained that the systems of water purification on waterside civil structures using porous concrete and feeding organisms with little maintenance

本研究系以多孔混凝土及投喂生物于滨水土木建筑物上，以实现少维护之净水系统。研究了多孔混凝土的水质净化性能和耐久性.主要结果如下：（1）选用合适的材料和孔隙特性，多孔混凝土具有较高的净水能力。（2）在低潮区存放两年的多孔混凝土的抗压强度最低，约为初始强度的一半（3）可以确认，多孔混凝土净水试验厂房中的摄食生物种类与（4）使用多孔混凝土的水净化试验工厂的沿海存款深底部是黑泥，因为氧气浓度低，另一方面，在该工厂的浅底部有少量的沿海存款。根据以上结果，可以认为滨海湾浅部有大量的Bivaivia，Bivaivia已经侵蚀了海岸存款。（5）利用多孔混凝土和投喂生物的滨水土木建筑物的水质净化系统，
