Abstract

The invention relates to the field of sewage treatment equipment, in particular to a rectification air flotation machine, and aims to solve the problems that in the prior art, a sewage treatment system is large in water flow disturbance and slow in floating process, and formation of effluent quality is easily affected. The rectification air flotation machine is technically characterized by comprising a separation area. The separation area comprises a flow guide assembly and alaminar flow assembly. The flow guide assembly is located above the laminar flow assembly and used for converting a horizontal movement water body into a vertical movement water body, and the laminar flow assembly is used for changing turbulent water flow into a laminar flow state. Through the flow guide assembly, water is converted from horizontal motion into vertical motion, and through the arrangement of the rectification assembly, water flow is changed into a laminar flow state from a turbulent flow state, so that suspended solids in sewage are in a very quiet state in any space of the air floatation separation area under the guidance of bubbles; therefore, the ascending speed of suspended matters can be greatly increased. And the suspended matter removing efficiency of air floatation is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a rectifying air flotation machine. Background technique [0002] The air flotation machine is a machine that uses small or tiny air bubbles to make impurities in the medium float out of the water. The air flotation device can be used for some fine impurities in the water body whose specific gravity is close to that of water, which is difficult to sink or float due to its own weight. [0003] Conventional air flotation surface load is 3-7m 3 / m 2 / h, the efficiency is very low, the main reason is that there is a short-flow phenomenon in the water flow inside the separation zone. In addition, the state of water flow inside the separation zone is turbulent. The Reynolds number RE>10000 or above, the suspended matter in this range is led by the air bubbles to float up, due to the large disturbance of the water flow, the floating process is very slow, and in...
