Oil molecules contained in the raw water are gradually adsorbed by the carbides, and after a while, the carbides are removed. Some float up and some settle down.
【００２２】これは炭化物が油の分子の他に残渣をも吸

の凝集体が浸入することがないからである。The middle part, especially the outer periphery, is water having a low oil content. In particular, the inside of the inflow prevention wall 11 is water containing almost no oil. This is shown in Fig. 1
This is because the coal particles and the aggregates do not enter the inside of the inflow prevention wall 11.

Both D) and normal hexane extractables content cleared the environmental standards, and it was found that there was no problem in flowing the water treated by the water purification device of the present invention to the sewage.
【００２９】特に、ｎ−ヘキサン抽出物質含有量は前記

かった。After the inventor stopped the inflow from the inflow port 9 and sufficiently aerated in the stirring (aeration) tank 4, the aeration was reduced to about 10%.
After stopping for a minute, it was found that the aggregates adsorbing the oil were separated vertically, and water close to fresh water was obtained as much as possible in the middle part.
【００３１】この水も前記基準を満たしていたものであ
