Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of sewage treatment, in particular, to a sewage treatment device for mechanical and electrical engineering. BACKGROUND

[0002] Mechanical and electrical engineering is a comprehensive application field of mechanical engineering and electrical engineering, covering the whole process from basic material selection to complex system integration, and widely serving scenes such as construction, industry, energy, etc. Its core content includes material and equipment application, professional technology implementation, building and industrial system construction, regulation and standard compliance, and project management, etc. Mechanical and electrical engineering also involves manufacturing industry, including mechanical manufacturing industry and electronic manufacturing industry. In the mechanical manufacturing industry and the electronic manufacturing industry, there are related processes such as forming, cutting and surface treatment of metal parts. During the actual operation of these processes, a certain amount of sewage is generated because water is used to clean the metal parts or to flush and cool the machining end of the machining equipment. Because the sewage contains metal ions and some chemical agents, it cannot be directly discharged and recycled.

[0003] In the prior art, the sewage containing metal impurities and chemical agents is generally treated by chemical precipitation. After the sewage is preliminarily filtered, it is discharged into a chemical deposition tank, lime milk is added to the sewage to remove metal ions from the sewage, and then the sewage is subjected to oxidation and ion exchange to remove the main metals and chemical components in the sewage. Subsequently, the sewage is subjected to permeation, bacterial disinfection and activated carbon filtration to completely treat the sewage.

[0004] However, the sewage generated in the field of mechanical and electrical engineering is different from the sewage discharged by large units. The sewage is generated by multiple small machining devices in the workshop. The amount of sewage discharged by each small machining device is limited. Therefore, due to the limitation of workshop design cost, it is not convenient to equip each machining device with a sewage treatment device. Generally, the sewage generated by multiple machining devices is collected and treated collectively. However, because the sewage contains large particles, a large amount of impurities will be retained in the collection pipeline during the collection of the sewage, which will cause blockage of the collection pipeline in the later stage. In addition, a large amount of impurities will be discharged into the chemical deposition tank together with the sewage, which will increase the amount of treatment agent used in the later stage.
