Document Type and Number:
WIPO Patent Application WO/2018/203381
Kind Code:
A1
Abstract:
[Problem] To activate microorganisms in wastewater via a high-speed jetting and rising flow and a high-speed circulating and rising flow from a jetting means, thereby removing scum produced within a storage tank. [Solution] To remove scum produced in wastewater within a storage tank 10 in which microorganisms are mixed, a jetting means 11 for generating a rising circling flow is installed in a bottom-surface location of the storage tank 10, the jetting means 11 introduces air from outside of the storage tank 10 to produce a high-speed jetting and rising flow and produce a high-speed circulating and rising flow in the wastewater X, and scum produced in the wastewater is removed via the high-speed jetting and rising flow and the high-speed circulating and rising flow in accompaniment with bubbling.
