<p><P>PROBLEM TO BE SOLVED: To provide a water purification system contributing to water purification because water shortage is on a global basis, and the water purification such as of tap water, industrial sewage, lake, and sea is widely required. <P>SOLUTION: In the water purification system, a bacteria proliferation tank is manufactured, and its function is not lowered by pouring a small amount of wastewater therein. This sewage purification system comprises the bacteria proliferation tank for proliferating bacteria decomposing dirts in a sewage tank (source) as a purification object and sewage. The water purification system purifies sewage by putting a small amount of bacteria proliferated in the bacteria proliferation tank into the sewage tank (source). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
