摘要

PROBLEM TO BE SOLVED: To install a spare waste water treatment tank, etc., for avoiding a partial waste water treatment tank, in which trouble is generated, without using a piping and a pump. ;SOLUTION: Each waste water treatment tank 1a, 1b, 1c is formed in hexagonal-pole structure, which has a regular hexagonal base and in which opposed side faces are formed mutually in parallel. The hexagonal-pole structure of each waste water treatment tank 1a, 1b, 1c is formed in the same shape and size. The directions of the bases of each waste water treatment tank 1a, 1b, 1c are aligned in the same direction, and the waste water treatment tanks are installed adjacently under the state, in which mutual side faces are brought into contact.;COPYRIGHT: (C)1999,JPO
