One-step continuous sewage acid mixing device

Abstract

The invention discloses a one-step continuous sewage acid mixing device comprising an outer tank body and an inner tank. The middles of the outer tank and the inner tank are penetratingly provided with a central cylinder, and the inner side of the inner tank is provided with spiral blades, a plurality of water pipes communicated with the inner chamber of the inner tank are arranged on the outer ring of the top of the inner tank, a plurality of first stirring blades are arranged on the outer sidewall of the inner tank, and a plurality of second stirring blades are arranged on the inner wall of the central cylinder on the upper side of the inner tank. A plurality of inner ring plates are arranged on the outer sidewall of the inner tank, and a plurality of outer ring plates are arranged on the inner wall of the outer tank corresponding to the positions of the inner ring plates. The one-step continuous sewage acid mixing device is novel and compact in structure, and can mix and match the water and the acid liquid several times, and only one motor for driving is needed. Energy consumption is low, and the water and the acid liquid can be completely mixed at one time to facilitate the application and promotion.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a primary continuous sewage acid mixing device. Background technique [0002] The pH value is a scale of hydrogen ion activity in a solution, and a measure of the acidity and alkalinity of a solution. When the pH value tends to 0, the solution is more acidic, on the contrary, when the pH value tends to 12, the solution is more alkaline, and when the pH value is around 7, the solution tends to be neutral. Common methods of comprehensive sewage treatment include: physical methods, chemical methods, physical and chemical methods and biological methods and so on. In the process of sewage treatment, it often needs to be carried out under a certain pH value, otherwise the specific treatment effect cannot be achieved. For example, if the wastewater is acidified and stripped, the pH value of the original wastewater is neutral or alkaline, and the pH value needs to be adjusted ...

AI Technical Summary

Problems solved by technology

[0003] Acid needs to be added to adjust the pH value of sewage. At this time, the full mixing of sewage and acid is very important. If the mixing is not uniform, the residence time of the reaction equipment in the next stage will be reduced, which will seriously affect the sewage treatment effect.
