Background
Heavy metal wastewater is one of the most serious industrial wastewater which pollutes the environment and has the greatest harm to human. Japanese public nuisance-water ensure disease and pain in the world after 20 th century and 60 th century shock, which are caused by the environmental pollution of mercury-containing wastewater and cadmium-containing wastewater, respectively. Therefore, the treatment of heavy metal wastewater is very important in all countries.
Treatment characteristics and basic principles heavy metals in wastewater are not decomposed and destroyed by various conventional methods, but only their existing positions are shifted and their physical and chemical forms are transformed. For example, after chemical precipitation treatment, heavy metals in wastewater are converted from a dissolved ionic state into a poorly soluble compound and precipitated, and then transferred from water to sludge; after ion exchange treatment, transferring metal ions in the wastewater to ion exchange resin; after regeneration, the regenerated waste liquor is transferred from the ion exchange resin to the regenerated waste liquor. In a word, the heavy metal wastewater forms two products after being treated, namely the treated water which is basically removed with heavy metals, and the concentrated product of the heavy metals. The treated water with the heavy metal concentration lower than the discharge standard can be discharged; if the water meets the water requirement of the production process, the water is preferably recycled. Heavy metals in the concentrated product have use value and are recycled as much as possible; without recycling value, to be disposed of harmlessly

the upper side of the filter plate (11) is provided with a groove (17) with a spiral structure; the sewage inlet (2) is eccentrically arranged relative to the axis of the hollow pipe (5);
the inner upper part of the filter cylinder (161) is hinged with a roller (168); an elastic rope (169) is wound on the roller (168); one end of the elastic rope (169) is connected to the elastic sheet (162), and the other end of the elastic rope (169) sequentially penetrates through the elastic sheet (162) and the filter cylinder (161) to be connected with a balancing weight;
a plurality of air bags (18) which are uniformly distributed are embedded in the side surface of the second auger along the spiral line direction; the upper end of the air bag (18) is communicated with the second auger through a third through hole, a fourth through hole is formed in one side, close to the hollow pipe, of the air bag (18), and a second spring is arranged in the air bag (18); one-way valves are arranged between the third through hole and the fourth through hole;
when the device works, wastewater is introduced into the box body (1), large-particle metal impurities in the wastewater are filtered through the filter plate (11), the metal impurities fall into the first auger (7) in the hollow pipe (5) from the first through hole (13), and the large-particle impurities are discharged from the discharge port along with the rotation of the first auger (7), so that the influence on the wastewater treatment efficiency caused by the simultaneous filtration of the large-particle impurities along with the wastewater is avoided, and the wastewater treatment effect is effectively improved; wastewater is enabled to permeate downwards through a first filtering hole (9) on a first auger (7), so that large-particle metal impurities are prevented from being brought out when being brought out; the filtered wastewater falls on the partition plate (14) and enters the hollow pipe (5), and the wastewater enters the plurality of metal ion filtering modules (16) under the filtering of the second biological filtering membrane (163) along with the rotation of the second packing auger (8) and is filtered simultaneously, so that the wastewater treatment efficiency is improved; the filtered wastewater with higher concentration is continuously compressed downwards along with the packing auger, when the wastewater reaches the bottom of the hollow pipe (5), a part of the wastewater still passes through the first biological filter membrane to enter the metal ion filtering module (16) due to higher pressure, and the rest wastewater with higher concentration is discharged from the sewage discharge outlet (4), so that the wastewater with higher concentration of heavy metal ions can be directly recycled, and the wastewater treatment effect and the wastewater treatment efficiency are effectively improved; after wastewater enters a filter cartridge (161) of a metal ion filter module (16), the elastic sheet (162) is extruded along with the rotation of a second auger (8), the middle part of the elastic sheet (162) is bulged, so that the space between the elastic sheet (162) and the lower part of the filter cartridge (161) is enlarged to generate negative pressure, wastewater above the elastic sheet (162) in the filter cartridge (161) is sucked into the lower part of the elastic sheet (162) through a fourth filter hole (165), and is filtered again through a third biological filter membrane (166) in the fourth filter hole (165), so that the wastewater is purified, when the auger rotates to be separated from the contact with the elastic sheet (162), the purified water is extruded from a water outlet (164) by the rebound of the elastic sheet (162) and falls into the bottom of a box body (1), and is finally discharged from a purified water outlet (3), the clean degree of wastewater treatment is effectively improved, and the efficiency of wastewater treatment is improved.
