Bidirectional sinking and floating type sewage suspended matter adsorption ball

Abstract

The invention discloses a bidirectional sinking and floating type sewage suspended matter adsorption ball, and belongs to the field of water treatment. According to the bidirectional sinking and floating type sewage suspended matter adsorption ball, when the adsorption ball is just put into sewage, an adsorption floating ball floats on the water surface to adsorb suspended matters on the water surface, and meanwhile, an adsorption sinking ball sinks into the sewage, and the constraint on a position control belt is released, so that the semi-free adsorption ball is separated from the adsorption sinking ball along with the position control belt, and the suspended matters in the water body are dynamically adsorbed, and the bidirectional adsorption of the suspended matters in the sewage is realized; and compared with the prior art, the adsorption ball is remarkably improved in adsorption efficiency for the suspended matters in the sewage; and along with the prolonging of the adsorption time, and under the influence of heat carried by sewage, the floating ball is controlled to gradually expand, so that the overall water discharge of the adsorption sinking ball is gradually increased, the buoyancy of the adsorption sinking ball is gradually increased, the adsorption sinking ball sinking in the sewage gradually floats, the state that the whole adsorption ball floats on the water surface is presented, and a worker is conveniently reminded to recycle the adsorption ball in time.

Description

technical field [0001] The invention relates to the field of water treatment, and more specifically relates to a two-way sinking and floating sewage suspended matter adsorption ball. Background technique [0002] Generally, when industrial sewage is discharged, it carries a certain amount of heat, which is generally higher than the ambient temperature. When it is discharged, the temperature needs to reach room temperature or lower than room temperature. Sewage usually contains a large number of suspended solids, and large suspended solids can be filtered. However, the removal efficiency of small particles of suspended solids by filtration is relatively slow, so they are generally removed by adsorption. In the prior art, it is convenient to recover the adsorption materials. Generally, light adsorption materials are used, which can float on the surface of the water body. However, the efficiency of this adsorption method is low, and the adsorption material cannot perform relati...

[0002] Generally, when industrial sewage is discharged, it carries a certain amount of heat, which is generally higher than the ambient temperature. When it is discharged, the temperature needs to reach room temperature or lower than room temperature. Sewage usually contains a large number of suspended solids, and large suspended solids can be filtered. However, the removal efficiency of small particles of suspended solids by filtration is relatively slow, so it is generally removed by adsorption. In the prior art, it is convenient to recover the adsorption materials. Generally, light adsorption materials are used, which can float on the surface of the water body. However, the efficiency of this adsorption method is low, and the adsorption material cannot adsorb the suspended solids in the water body with relatively high efficiency.
