Research On An Oxygenated Water Purification System With Micro-bubble Generators

Pollution of water resource, water environment and the technology of purifying water are regarded increasingly. Some investigation and analysis for micro-bubble's generating and mass transferring are started with the technology of oxygenated water purification and the theory of micro-bubble's generating. The results indicate that the ejector is a kind of efficient equipment which can enrich the oxygen of sewage. Based on of the method of the best performance curve experience equation, a 1-D theoretical model is established with some assumptions and simplifications of the ejector's operation process. A new design calculation of the ejector is carried out with the optimization of bubbles' size. In the new method, continuity equation, momentum equation and energy equation are all to be considered. Then the ejector's structure parameters are worked out with the iterative method. The result shows that they are more accurate than those parameters obtained from a single experience equation. A set of oxygenated water purification system is composed of the ejector, the pressure swing adsorption system and the efficient mixer by jetting from slot. It can increase the oxygen indicator of sewage independently, expediently and rapidly, and be used in not only sewage's concentrative processing but also retaining and renovating water quality in water area. Oxygenated water purification system's feasibility and practicability are validated by academic analysis. It has comprehensive application foreground and spread value.
