Equipped with pH meter and soda acid automatic liquid adding device on described first pH regulator pond, the first pH regulator pond liquid feeding side pipeline is additionally provided with effusion meter.
Described flocculation sedimentation tank is furnished with agitating device, and is provided with flocculant accumulator tank, and groove is built with PAM(polyacrylamide) flocculant.
Described equipment for separating liquid from solid bottom is connected by pipeline and the second top, pH regulator pond, and equipment for separating liquid from solid is also equipped with sewage draining exit.
This utility model has the advantages that compared to existing technology
1, this utility model is the processing means of a kind of heavy metal wastewater thereby, and its structure is relatively easy, has saved cost, it is adaptable to polytype enterprise and the heavy metal containing wastewater treatment of units concerned.
2, the most all having pH regulator pond, it is ensured that precipitate and adsorb the different needs to pH, two adsorption tank designs improve the utilization ratio of adsorbent, and guarantee to process standard water discharge discharge.
Accompanying drawing explanation :
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-input duct;2-the first pH regulator pond;3-soda acid automatic liquid adding device;4-water pump;5-flocculation sedimentation tank;6-agitator;7-solid-liquid separation tank;8-the second pH regulator pond;9-valve;10-the first adsorption tank;11-the second adsorption tank;12-filtering ponds.
Detailed description of the invention:
The most just combine accompanying drawing 1 this utility model device is described further.
This utility model structure is as it is shown in figure 1, heavy-metal waste water treatment device of the present utility model, including the first pH regulator pond 2 connected by pipeline successively, flocculation sedimentation tank 5, solid-liquid separation tank the 7, second pH regulator pond 8, adsorption tank and filtering ponds 12.Adsorption tank is formed in parallel by the first adsorption tank 10 and the second adsorption tank 11, and two adsorption tank both sides are interconnected, and their liquid feeding side all connects with the second pH regulator pond 8, and tapping side all connects with filtering ponds 12.
Inlet channel 1 is connected with the first pH regulator pond inlet, and the first pH regulator pond liquid outlet is connected with the inlet on flocculation sedimentation tank top, and is provided with pump connecting on pipeline;Bottom flocculation sedimentation tank, liquid outlet is connected with the water inlet on solid-liquid separation tank top, and is provided with pump connecting on pipeline;The liquid outlet of solid-liquid separation tank bottom and the inlet on the second top, pH regulator pond are connected, and are provided with pump connecting on pipeline;The liquid outlet in the second bottom, pH regulator pond connects the inlet on the first and second adsorption tank tops respectively through pump, and is provided with valve connecting on pipeline;The liquid outlet on the first and second adsorption tank tops is all connected with filtering ponds, and is provided with valve connecting on pipeline;Liquid outlet bottom first and second adsorption tanks is the most all connected with filtering ponds, and is provided with pump connecting on pipeline.
This utility model, as a example by removing the heavy metal lead in waste water, uses process as follows:
nullHeavy metal-containing waste water is entered the first pH regulator pond 2 by input duct 1 under water pump effect,The soda acid automatic liquid adding device 3 internal by it regulates the pH value required for flocculation sediment with pH meter,By water pump 4, water is inputted in flocculation sedimentation tank 5 by pipeline subsequently,Mixing speed and mix homogeneously is ensured by agitator 6,Solid-liquid separation tank 7 is entered after reaction completely,The second pH regulator pond 8 is fed the water into by water pump and pipeline again after being separated by sewage draining exit,The pH value required for absorption is regulated with pH meter equally by its internal soda acid automatic liquid adding device,Close the valve 9 of the second adsorption tank 11,Waste water is allowed to enter the first adsorption tank 10,First adsorption tank 10 is hung with and fills adsorbent with the pore string bag,After adsorption treatment certain time,Guarantee the now most heavy metal of adsorbent,Adsorbent in the pore string bag is taken out discarded,After being adsorbed by first adsorption tank 10, waste water pumps into the second adsorption tank 11 again,Second adsorption tank 11 is hung with adsorbent with pore string bag dress equally,Carry out second adsorption,Second adsorption tank 11 processed waste water pumps into filtering ponds 12 by pump and carries out filtering water outlet,And now the adsorbent in the second adsorption tank 11 can utilize by secondary.
