Gas-propelled self-stirring combined purification tank

Abstract

The gas-propelled self-stirring combined purification tank of the present invention includes an outer wall and a partition arranged in the outer wall, and the partition divides the inner cavity of the outer wall into first, second, third and fourth cells; it is characterized in that: A first opening is provided between the first and second slots, a second opening is provided between the second and third slots, and a third opening is provided between the third and fourth slots; the first opening is provided with There is a feed pipe, and a discharge pipe is provided in the middle and upper part of the fourth cell; a U-shaped tube that can automatically stir the matrix is ​​arranged on the partition between the first cell and the second cell. In the combined purification tank of the present invention, a U-shaped tube is arranged on the dividing plate between the first cell and the second cell to realize the automatic stirring function of the substrate, and accelerate the purification and processing speed of the substrate; Adding the auxiliary stirring device simplifies the structure of the purification tank, reduces the production cost, has remarkable beneficial effects, and is convenient for application and popularization.

Description

technical field [0001] The invention relates to a gas-propelled self-stirring combined purification tank, more specifically, to a combined purification tank which uses gas to periodically stir the substrate during the substrate purification process. Background technique [0002] The existing high-concentration organic waste generally adopts anaerobic fermentation process to produce biogas while treating the waste. However, in order to ensure the normal operation of the treatment facility, stirring equipment must be installed in the reaction tank, which not only increases the complexity of the structure, but also increases the operating cost. Seriously restrict the popularization and application scope of its technology. [0003] In terms of sewage treatment, there is a lack of a suitable method, which has a simple structure and can achieve the effect of simultaneous denitrification and phosphorus removal. The problem that needs to be solved urgently is: there is no pollutan...
