The invention belongs to the technical field of waste water treatment equipment, and specifically relates to waste water treatment equipment for heavy metal processing. Connect the No. 1 auger and the No. 2 auger, and the rotation direction of the No. 1 auger and the No. 2 auger are opposite; the No. 2 auger is provided with a No. 2 filter hole, and a No. 1 biological filter is installed in the No. 2 filter hole; hollow The tube is provided with a filter plate, a separator and several metal ion filter modules; the metal ion filter module is connected to the hollow tube; the present invention filters and discharges the large-particle metal impurities in the wastewater through the filter plate, avoiding the influence of large-particle impurities Efficiency of wastewater treatment; the wastewater that removes large particles of impurities enters the hollow tube, and the wastewater enters several metal ion filtration modules under the filtration of the No. 2 biofiltration membrane with the rotation of the No. 2 auger, and is filtered at the same time, which improves the efficiency of wastewater treatment. efficiency.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment equipment, in particular to wastewater treatment equipment for heavy metal processing. Background technique [0002] Heavy metal wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater. Minamata disease and Itai-itai disease, which shocked the world in Japan in the 1960s, were caused by mercury-containing wastewater and cadmium-containing wastewater polluting the environment respectively. Therefore, all countries attach great importance to the treatment of heavy metal wastewater. [0003] Treatment characteristics and basic principles The heavy metals in wastewater cannot be decomposed and destroyed by various common methods, but can only transfer their location and change their physical and chemical forms. For example, after chemical precipitation treatment, heavy metals in wastewater are transformed from dissolved ions into i...
