Environment-friendly liquid conveying device for sewage pretreatment

Abstract

The invention discloses an environment-friendly liquid conveying device for sewage pretreatment. Directed at the problems of easy pipe blockage and easy generation of stink in the circumstance of no pretreatment, the invention puts forward the following scheme that: the device includes a base plate, a primary treatment box is welded to one side of the outer wall at the top of the base plate, and an aeration treatment box is welded to one side of outer wall at the top of the base plate close to the primary treatment box, a settling box is welded to one side of outer wall at the top of the baseplate close to the aeration treatment box, and a first through hole is arranged one side outer wall of the primary treatment box close to the top. According to the invention, silk-like objects like hair and the like in sewage are wound at blades, thus avoiding further movement and not causing pipe blockage, also broken filaments are fine, have adsorbability, and can adsorb fine impurities, hydraulic rotation separates sand from organic matters, sand sinks, stink can be avoided, pretreatment is carried out, and the subsequent sewage sterilization and disinfection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid conveying devices, in particular to an environment-friendly liquid conveying device for sewage pretreatment. Background technique [0002] With the development of society, the number of small and medium-sized enterprises continues to increase. Some small and medium-sized enterprises will produce a large amount of wastewater after production. If the wastewater is directly discharged to the outside world, it will cause river pollution and even kill fish and shrimp. Therefore, wastewater treatment is a problem that cannot be ignored. . Existing wastewater treatment focuses on the cleaning of pollutants, but does not pay attention to the pretreatment and transportation of wastewater in the early stage. This will not only reduce the efficiency of wastewater treatment, but also cause blockage to pipelines and affect follow-up work. [0003] After searching, the Chinese patent authorization number is CN1...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents have the following deficiencies: when the sewage is transported without pretreatment, it is easy to cause blockage of pipes and mesh products, and the residues in the reaction tank are likely to cause stench, etc., and the above-mentioned patents cannot solve such problems. Therefore, it is urgently needed An environmentally friendly liquid delivery device for sewage pretreatment to solve the above problems
