Sewage treatment device with strong applicability

Abstract

The invention discloses a sewage treatment device with strong applicability, which comprises a settling tank. A vertical coagulation pipeline is communicated with the upper left side of the settling tank. The inside of the coagulation pipeline is provided with a stirring shaft. The left and right ends of the shaft are provided with bearings, the left and right ends of the stirring shaft are fixedly connected with the inner ring of the bearing, the outer end of the outer ring of the bearing is fixedly connected with the inner wall of the coagulation pipeline through a connecting rod, and the stirring shaft The outer wall of the settling tank is provided with stirring blades, the inner wall of the coagulation pipeline is inlaid with an ultrasonic generator, the middle and lower end of the settling tank is equipped with a pulp recovery valve, and the top of the settling tank is connected with a water outlet pipe; this highly applicable sewage treatment The device has fast sewage treatment efficiency, high flocculant utilization rate and prevents coagulation pipeline from clogging, which saves resources, has strong applicability, and is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device with strong applicability. Background technique [0002] With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and is currently in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. Among them, the papermaking industry ranks first among the five high water consumption industries in my country. The water consumption per ton of paper in domestic paper mills is as high as 100 cubic meters, which is almost 10 times the world average level. Therefore, the water source pollution and environmental pollution caused by my country's papermaking industry And the waste of water resources is very serious. At present, some manufacturers in my ...

Problems solved by technology

[0004] However, the single use of ultrasonic mixed flow to treat papermaking wastewater has low flocculation efficiency; moreover, the flocculation channels of traditional sewage treatment devices are easy to block, and it takes time and effort to clean up, which increases the cost of sewage treatment; therefore, traditional sewage treatment devices need to be improved.
