Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to energy-saving sewage treatment equipment. Background Art

[0002] Wastewater treatment: The process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering, and is increasingly entering the daily lives of ordinary people;

[0003] When sewage treatment equipment is in use, it is necessary to use chemical agents to treat impurities in sewage. Therefore, it is necessary to mix the chemical agents with sewage through stirring. The current sewage treatment equipment only uses a single stirring method for mixing, which will produce a "swirling" phenomenon during stirring. The so-called "swirling" phenomenon is that the liquid forms a funnel-shaped vortex under the action of centrifugal force and tangential flow. The greater the rotation speed, the greater the degree of concavity of the vortex. Once this happens during the stirring process, the relative movement of the liquid material stirring and mixing will be weakened, resulting in a worse mixing effect of the chemical agent and sewage, which will affect the effect of sewage treatment. Continuous stirring is required, which will increase energy consumption. In addition, since some impurities will be mixed in the sewage, when filtering the sewage, if the impurities block the filter plate, it will affect the filtration speed. Therefore, how to solve this problem is what we need to consider. Utility Model Content
