Background

In the sewage treatment process, especially when suspended solids and petroleum pollutants are removed, the air flotation technology is widely adopted, and the principle is that a flocculating agent is added into sewage, the sewage is uniformly mixed with the flocculating agent through eddy reaction or mechanical stirring, the suspended solids or floating oil in the sewage are subjected to flocculation reaction to generate flocs, and then micro bubbles generated by various methods are released into the water through a diffusion device. The bubbles contact with the flocs and attach to the flocs to lighten the flocs, so that the flocs quickly float upwards and are removed by a residue scraper, thereby achieving the purpose of purifying water.

At present, the air floatation technology has various relevant equipment forms, specifically, the realization forms include vortex reaction and mechanical stirring reaction. The eddy reaction is divided into an external condition and an internal condition, at present, when the eddy reaction is built internally, because the built-in eddy flow reactor is single eddy flow, the single eddy flow can cause wide eddy flow spread range, so that the air flotation machine occupies a very large space, the contact area of flocculate and bubbles is huge, and the sewage treatment efficiency is influenced. The height of the single vortex reactor is very high, the upper opening is very large, so that a contact area and a clarification area are arranged at the top end of the vortex reactor and cannot be made very deep, and therefore, when impact load is met, namely under the condition that the sewage inflow is suddenly increased, flocculate is easily taken out of equipment, and the effluent exceeds the standard.
