Beschreibung
Zusammenfassung:	The invention provides a biological filter device of purifying industrial circulating water. The biological filter device comprises a tank, an aeration cylinder, a water inlet ring, an air inlet ring, an air inlet pipe and a sewage collecting chamber. The aeration device is arranged in the middle of the tank, and the sewage collecting chamber is arranged on the bottom of the tank. The water inlet ring is an annular pipeline arranged along the inner wall of the top of the tank, a circle of drainage holes are disposed on the bottom of the water inlet ring, and the water inlet of the water inlet ring is communicated with the water inlet of the tank. The aeration cylinder is a cylindrical shell with up and down openings, the air inlet ring is an annular pipeline arranged along the outer wall of the bottom of the aeration cylinder, and aeration holes are disposed on the contact surface of the air inlet ring and the aeration cylinder. The air inlet ring is connected with an air inlet on the tank by the air inlet pipe, and the water outlet of the tank is disposed above the water inlet. The device can make the suspended biological filter material in the filter form internal up and down circulatory motion with the water, can make aged biomembrane fall off by the motion of the filter material in the water and collision friction with each other, can improve the biological purification efficiency, can remove the ammonia nitrogen and nitrite, and can automatic clean the biological filter material.
