Abstract

A system for purifying contaminated water coming into sea or lake by introducing it into a water area enclosed by a wave breaker for utilizing tidal energy, etc. before the water comes into sea or lake. In the water area, the wave breaker accelerates the effect of aerating water, thus increasing the amount of dissolved oxygen and enhancing the activity of contaminated water. Plankton and suspended substances, which are water contaminants, are preyed upon by fish or adsorbed by seaweed growing in a multi-void breaker. Flocculation of the contaminants is also accelerated by the effect of the breaker, and settling of contaminants is accelerated by the calmness of waves in the enclosed water area. Water discharged from the breaker-enclosed area becomes clean.

However, it is intended to be released into the waters of a clean sea (lake).

こ れ ら の作用 に よ っ て 、 水中 の汚染物質の フ ロ ッ ク 化 も促進 さ れ る 。  These actions also promote the flocculation of pollutants in water.
さ ら に 、 こ の 砕波堤で包囲 さ れ た海 （湖） の zf 域 （各図面の番 号 3 ) で示す水域は静寂であ り 汚染物の沈降が促進 さ れ る 。  In addition, the water area indicated by the zf area (No. 3 in each drawing) of the sea (lake) surrounded by this breakwater is quiet, and sedimentation of contaminants is promoted.

It is also useful for damage control.

It is necessary to have enough waves and a water surface that can be closed. In addition, depending on the quality and quantity of the contaminated water flowing in, the size of the waves and tides, and the water quality and depth of the sea (lake) itself, the length of the crushed levee may be limited.
