The super-hydrophobic material is used as the filtering filler, and when gas and water flow in a reverse flow manner in the filtering filler, the filtering filler is wrapped by the airflow to form an air film layer, so that the filtering filler is not in direct contact with the water, and the non-blocking operation is realized.

2. The number of the water distributors is two, the liquid inlet pipe comprises a water inlet pipe and a water purification medicine liquid pipe, one water distributor is connected with the water inlet pipe, and the other water distributor is connected with the water purification medicine liquid pipe; the water and the water purification liquid medicine separately enter the separation tank, so that the flow of the water and the water purification liquid medicine is convenient to control.

3. Two water distributors are the setting from top to bottom, and the water distributor of connecting the inlet tube is located the top, and the water inlet is advanced to get into the suspended solid enrichment layer of holding back and is got into the separating layer again, and when adding medicine operation, the suspended solid enrichment layer forms the reaction chamber under the effect of gas stirring, and the medicament fully mixed reaction with water possesses high medicament utilization ratio.

3. The upper portion of knockout drum is equipped with the toper chamber, and the blast pipe is connected in the top in toper chamber, and the suspended solid floats under the buoyancy, does benefit to the suspended solid and is smugglied secretly the discharge by the air current.

4. The gas-liquid-solid three-phase interface in the separation tank is positioned in the conical cavity and is higher than the water distributor, and in the process of gas-water countercurrent filtration, the gas flow forms interception thrust, so that the enrichment of suspended matters in an interception layer is avoided, and high-load treatment is realized.
