Description

Sewage treatment device based on combination of membrane concentration and heterogeneous catalyst

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device based on combination of membrane concentration and a heterogeneous catalyst.

Background

The membrane concentration equipment effectively separates effective components and liquid molecules by utilizing directional separation so as to achieve the purpose of concentration and separation of target objects, is an innovative and high-efficiency concentration equipment different from the traditional process, and has the characteristics of low energy consumption, normal-temperature operation, small influence on products and the like compared with the traditional heating concentration. The application range comprises: the process of membrane concentration is divided into two operation stages of preconcentration and percolation, the sewage is divided by the difference of the particle sizes of large and small molecules, the sewage needing to be recovered and treated is promoted to gather a large number of small molecules, so that a concentration state required by percolation is formed, when the process reaches a stationary state, the concentration of a solution on the surface of a feed liquid membrane is obviously higher than that of a main solution, the phenomenon is called concentration polarization, the solute is directionally diffused into a feed liquid main body in a concentration boundary layer of the solute near the membrane, and meanwhile, as water has higher diffusion efficiency than the solute, the solute is more easily diffused and permeated in the membrane, so that an active layer on the surface of the membrane is hydrophilic for the separation of an aqueous solution, and most of the solute is intercepted on the surface of the membrane in the concentration polarization reverse osmosis process. In the sewage treatment process, as the membrane body is positioned in water, the solute accumulated on the surface of the membrane cannot be cleaned in time in an artificial cleaning mode, and the long-time accumulation of the solute easily affects the normal use of the membrane body.
