Background technique

At present, all kinds of sewage produced in industrial production and civil fields include organic matter, inorganic matter, garbage suspension, sediment and so on. In order to achieve the treatment effect of these sewage, large-scale treatment equipment is generally used. These equipment are huge and have complete functions, but they often require a lot of capital, manpower, and material resources, and occupy a large area. This is only suitable for large-scale Medium-sized enterprises or places with relatively concentrated production and residential population. Sometimes poor sewage treatment will cause secondary pollution to the surrounding environment, which has a relatively large impact. For many small and medium-sized enterprises or places where the population is scattered, it is difficult for such large sewage treatment equipment to play a role. In production and life, the generation of sewage is a ubiquitous phenomenon, and it is impossible to treat these domestic sewage in a centralized and large-scale manner, especially in places where there is a shortage of space. How to adopt corresponding treatment methods for different sewage, with complete functions and compact structure, which not only achieves different sewage treatment effects, but also saves investment and occupies less land is a major problem that the existing sewage treatment equipment urgently needs to solve. the

The multifunctional composite sewage purifier is a sewage purification device used for treating sewage generated in production and life. According to the characteristics of sewage, it is composed of two levels of sewage treatment devices with different functions. The first stage is a centrifugal separation device. The sewage from production and life enters the centrifugal separation device from the sewage inlet. Under the action of the power transmission group, the centrifugal rotor is driven to rotate, and the coarse particles in the sewage are centrifugally suspended under the action of its own gravity and centrifugal force. Separation and centrifugal sedimentation separation; the coarse particles that are equal to or larger than the volume of the sewage solution sink by themselves or are thrown to the edge to sink and separate, and the coarse particles that are smaller than the volume of the aqueous solution float on it. With the rotation of the centrifugal rotor, These materials are continuously pushed up or out into the dross outlet and pushed out, also being separated first. According to the different components of the sewage, add appropriate amount of different additives to the centrifugal separation device at the same time, under the interlaced action of the rotating stirring of the centrifugal rotor and the stirring up and down of the aeration device, the additives evenly have physical and chemical effects with the harmful components in the sewage , to purify sewage; the sewage separated by strong centrifugation by the centrifugal separation device is fully stirred evenly with additives, and then enters the water delivery hollow shaft from the bottom valve through the water-absorbing mesh screen, and enters the sedimentation filtration separation device through the connecting pipe. After the sewage reaches the sedimentation, filtration and separation device through the connecting pipe, the sedimentation, filtration and separation device is equipped with a filter layer, which can precipitate, filter and absorb harmful substances in the sewage, and is purified through further sedimentation and separation and filtration of the filter layer.
