ABSTRACT:
The waste water treatment apparatus includes a first water tank which has an upper part and a lower part. The upper part has an air diffuser, and calcium carbonate mineral is packed in the upper part. The calcium carbonate mineral in the upper part is strongly fluidized by aeration by the air diffuser to treat waste water in the upper part through its chemical reaction with the waste water. The calcium carbonate mineral settles in the lower part and serves as an immobilizing carrier for microorganisms to execute microbial treatment of the water.
