Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to an arsenic removal filtration device for gallium arsenide production wastewater. Background Technology

[0002] The synthesis, growth, cutting, grinding, polishing, and cleaning of gallium arsenide crystals generate a large amount of arsenic-containing wastewater. Currently, the treatment of this type of wastewater mainly focuses on arsenic removal through chemical precipitation. This method involves adding sodium hypochlorite and chlorine dioxide as oxidants to pre-oxidize the arsenite ions in the wastewater, followed by the use of ferric chloride and polyaluminum chloride as coagulants to convert dissolved arsenic into insoluble arsenic precipitates, thus achieving arsenic removal.

[0003] Existing filtration devices on the market use foam boards on the surface of the water when extracting filtered water from the sedimentation tank. One end of the pumping pipe passes through the foam board and extends into the sedimentation tank. Although this ensures that the pumping pipe opening is always at the clear liquid level on the surface, the suction force during pumping still pulls the sediment at the bottom to the surface, causing blockage of the pump and affecting the filtration efficiency of the device. Therefore, there is a need to provide a gallium arsenide production wastewater arsenide removal filtration device to solve the above problems. Utility Model Content
