Problems solved by technology

The waste on the surface of the bubbles is selectively absorbed. The separation efficiency depends mostly on the number and volume of the bubbles, and the other part depends on the difference in surface activity. The traditional sewage treatment system has the following obvious disadvantages: 1. The device takes up a huge space, which greatly improves the production capacity. Cost and operating cost; 2. The output (bubble density and flow rate) cannot respond to the input parameters (gas supply and pump speed) immediately, and lacks the flexibility of production. Therefore, a multi-stage aeration that solves the above problems is proposed. device is necessary

Abstract

The invention relates to the field of sewage treatment, in particular to a multi-segment aeration generator. The multi-segment aeration generator comprises a generator body and a pressure monitoring device installed on the generator body. The generator is characterized by further comprising a Venturi nozzle, a capillary and a concentrative pipe, one end of the capillary is connected with the Venturi nozzle, and the other end of the capillary is connected with the concentrative pipe. The multi-segment aeration generator is novel in design, the Venturi nozzle and the concentrative pipe are combined so that continuous and stable fine foam can be provided, and meanwhile output change can be immediately conducted when input operation parameters are changed. The aeration generator is used for controlling air supply and pump speed so as to generate proper foam density and size for later treatment, and market prospects are good.

Description

Technical field [0001] The invention relates to the field of sewage treatment, and more specifically, to a multi-stage aeration generator and a sewage treatment method. Background technique [0002] At present, for nearly a century, Dissolved Air Flotation (DAF) has been widely used in sewage treatment. The dissolved air flotation process will produce fine bubbles. Hydrophobic particles leave the liquid, where adsorbed bubbles concentrate or filter waste (molecules, colloids or large particles). The bubble surface waste is selectively absorbed. The separation efficiency depends mostly on the number and volume of bubbles, and the other part depends on the difference in surface activity. The traditional sewage treatment system has the following obvious disadvantages: 1. The device takes up a huge space and greatly improves production. Cost and operating cost; Second, the output (bubble density and flow rate) cannot respond to the input parameters (air supply and pump speed) in re...
