Petal-shaped falling-type adsorption ball for suspended solids in sewage

Abstract

The invention discloses a petal-shaped withering-type adsorption ball for suspended solids in sewage, and belongs to the field of sewage treatment. The petal-shaped withering-type adsorption ball for suspended solids in sewage is characterized in that after the adsorption ball is put into water, a water-soluble layer is gradually dissolved, and falling petals on the outer side gradually fall off from the adsorption ball from outside to inside like flower petal withering. On one hand, the inner sides and the outer sides of the fallen petals can adsorb suspended solids, and on the other hand, the extruded parts on the inner sides of the fallen petals expand, so that the contact area between the adsorption ball and sewage is remarkably increased, and the adsorption efficiency of the adsorption ball on the suspended solids in the sewage is improved. Meanwhile, the contact area of the adsorption ball and sewage becomes larger and larger as the adsorption ball is put into the sewage, the efficient adsorption duration of the adsorption ball on suspended solids in water can be remarkably prolonged, the problem that the timeliness of adsorption of suspended solids is poor in the prior art is effectively solved, then the recovery and replacement frequency of the adsorption ball is remarkably reduced, and the workload of workers is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment, and more specifically relates to a petal-shaped withering adsorption ball for suspended matter in sewage. Background technique [0002] From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage is mainly divided into the following two categories. [0003] Industrial Wastewater: Wastewater from manufacturing, mining and industrial production activities, including runoff live leachate from industrial or commercial storage, processing, and other wastewater that is not domestic sewage. [0004] Domestic sewage: sewage from residences, office buil...

Problems solved by technology

[0007] In view of the problems existing in the prior art, the object of the present invention is to provide a petal-shaped withering type adsorption ball for suspended matter in sewage. After the adsorption ball is put into water, the water-soluble layer gradually dissolves, and the outer withered and fallen petals are removed from the adsorption ball. Like a flower petal withering, it gradually falls off from the outside to the inside. On the one hand, both the inside and outside of the withered and exfoliated petal can absorb suspended matter. The contact area between the ball and the sewage, thereby improving its adsorption efficiency for suspended solids in the sewage, and at the same time, it can realize that as the time of being put into the sewage becomes longer, the contact area with the sewage will become larger and larger, which can significantly extend the adsorption capacity of the adsorption ball. The length of time for efficient adsorption of suspended solids in water effectively overcomes the problem of poor timeliness of adsorbing suspended solids in the prior art, thereby significantly reducing the frequency of recovery and replacement of the adsorption ball and reducing the workload of staff
