Gas push type self-mixing combined purifying tank

Abstract

The invention discloses a gas push type self-mixing combined purifying tank which comprises an outer wall and baffle plates arranged in the outer wall, wherein the baffle plates are used for segmenting a cavity inside the outer wall into a first slot case, a second slot case, a third slot case and a fourth slot case. The gas push type self-mixing combined purifying tank is characterized in that a first opening is arranged between the first slot case and the fourth slot case, a second opening is arranged between the second slot case and the third slot case, a third opening is arranged between the third slot case and the fourth slot case; a feeding pipe is arranged at the first opening, a discharging pipe is arranged at the middle-upper part of the fourth slot case; a U-shaped pipe capable of automatically mixing a matrix is arranged on the baffle plate between the first slot case and the second slot case. According to the combined purifying tank provided by the invention, by arranging the U-shaped pipe on the baffle plate between the first slot case and the second slot case, an automatic mixing function of the matrix is realized, and the purifying and treating speed of the matrix is increased. Because an auxiliary mixing device is not required to be added, the structure of the purifying tank is simplified, the manufacturing cost is lowered, the beneficial effect is remarkable, and thus the gas push type self-mixing combined purifying tank is convenient to apply and popularize.

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...

AI Technical Summary

Problems solved by technology

The problem that needs to be solved urgently is: there is no pollutant treatment system that can anaerobically treat high-concentration organic waste, and is suitable for removing pollutants such as nitrogen and phosphorus in low-concentration sewage, so that the scope of use of treatment facilities is limited In a certain range, the scope of application is narrow
