PROBLEM TO BE SOLVED: To provide a wastewater purifying apparatus having a simplified structure, requiring no power source, reducing the occurrence amount of waste and operated in reduced maintenance frequency.
SOLUTION: The treatment tank 2a of the wastewater purifying apparatus 1 is divided into the front chamber 8a and the rear chamber 9a by the vertical partition wall 3a, the partition wall 3a is filled with zeolite 5, the water inlet port 10a of the treatment tank 2a is formed at a position higher than a water outlet port 11a and the wastewater flowing into the water inlet port 10a of the treatment tank 2a passes through the zeolite filling port 4 of the partition wall 3a from the front chamber 8a, laterally flows toward the rear chamber 9a, and flows out of the treatment tank 2a from the water outlet port 11a. The treatment tanks 2b, 2c and 2d, each of which has the same constitution as the treatment tank 2a, are arranged in series and the water outlet port of the upstream treatment tank is formed at a position higher than the water inlet port of the downstream treatment tank.
