Semiconductor wastewater defluorination treatment device

Abstract

The invention relates to the technical field of semiconductors, and discloses a semiconductor wastewater defluorination treatment device which comprises a shell, and a treatment chamber is arranged on the outer side of the shell. A gear rotates; a rotating assembly rotates synchronously; a rotating plate rotates intermittently in a reciprocating mode; a clamping frame moves up and down intermittently; a lower plug is far away from a lower socket; an upper plug is clamped with an upper socket; and two heaters are controlled to operate in a staggered mode, so that repeated use of an activated aluminum oxide layer; operation of the heaters and drying treatment of the activated aluminum oxide layer are facilitated. The activated aluminum oxide layer can be recycled; the subsequent adsorption effect is prevented from being influenced by excessive adsorption capacity; the wastewater defluorination treatment effect is effectively improved; a rotating plate intermittently rotates in a reciprocating manner to drive two clamping rods to intermittently move up and down; two flow limiting rods are staggered to extrude a flow dividing pipe of a treatment chamber; and the flow direction of wastewater is automatically controlled; the defluorination treatment operation can be continuously carried out, therefore the wastewater treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a semiconductor wastewater defluorination treatment device. Background technique [0002] The semiconductor industry is an industry that is very dependent on water resources, and it is also an industry with high water consumption. Therefore, water conservation and waste water recycling have become important measures for semiconductor companies to deal with the water shortage crisis, especially waste water recycling, which can not only reduce the demand for water resources, but also reduce production costs and reduce environmental pollution. Because semiconductor wastewater contains fluorine, if you drink water that does not meet the required fluorine content for a long time, it will cause great harm to human health. At present, when defluorinating wastewater, it is necessary to treat the defluorinating mechanism at regular intervals to avoid long-term use of the defluorin...

AI Technical Summary

Problems solved by technology

At present, when defluorinating wastewater, it is necessary to treat the defluorinating mechanism at regular intervals to avoid long-term use of the defluorinating mechanism and reduce its ability to absorb fluorine in wastewater. However, it is necessary to suspend the defluorinating process during operation. Not very convenient, and seriously reduce work efficiency, can not meet the actual processing needs
