Operation method of low intensity supersonic waves for strengthening treatment effect of continuous flow biological reaction tank

Abstract

The invention relates to an operation method of low intensity supersonic waves for strengthening the treatment effect of a continuous flow biological reaction tank. A supersonic generator is arranged at a return sludge pump well of a municipal sewage plant; a part of return sludge is treated by supersonic waves intermittently for a plurality of times or is treated by the supersonic waves continuously for two times; and the sludge needing to be treated by supersonic waves returns to the biological reaction tank together with the sludge being and without being radiated and treated by the supersonic waves. The low intensity supersonic waves improve the capacity for treating swage by improving the activity of microbes in activated sludge in a biological treatment system, and further effectively improve the quality of water after being treated.

Description

Technical field The invention relates to an operation mode for enhancing the treatment effect of a continuous flow biological reaction tank with low-intensity ultrasonic waves. It is a process for enhancing the biological treatment of continuous-flow sewage by using low-intensity ultrasonic waves, which improves the microbial activity of activated sludge in a biological treatment system. Sewage treatment capacity, thereby effectively improving the effluent quality. Background technique In the current field of sewage treatment technology, the activated sludge method is one of the most widely used technologies. With the extensive application of activated sludge method in actual production and continuous technological innovation and improvement, especially in recent decades, based on in-depth research and discussion on its biological reaction and purification mechanism, activated sludge method is The theory of science, reaction kinetics, and technology have made great progress, a...
