<p><P>PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus capable of reducing the cost of equipment investment and eliminating the deformation, or the like, of a tank due to water pressure. <P>SOLUTION: In the wastewater treatment apparatus equipped with a plurality of tanks (a solid-liquid separation tank 10, a treatment tank 20 and a sedimentation separation tank 30) for applying various treatments to inflow wastewater, a plurality of the tanks are formed by partitioning one tank by partition plates 2 and 3 and equipped with reinforcing members for preventing tank deformation due to water pressure. Both side edge parts 2a and 3a of the partition plates 2 and 3 are joined to both tank walls in a close contact state by screws 2b and 3b to form the reinforcing members. <P>COPYRIGHT: (C)2003,JPO</p> |
