Example Embodiment

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] The purpose of the present invention is to provide a sewage treatment device for a finishing machine with good sewage treatment effect and high treatment efficiency, so that the sewage treatment effect in the existing sewage treatment device for a finishing machine is poor and the sewage treatment cannot be continued, resulting in low treatment efficiency The problem was solved.
[0025] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Such as figure 1 As shown, the present invention provides a sewage treatment device for a finishing machine, comprising a pH adjustment chamber 1, a flocculation chamber 15, a metal capture chamber 2, a centrifuge 3, a biological oxidation chamber 4, and a circulating water tank 5, which are sequentially connected. A pH sensor is provided in the pH adjustment chamber 1, and a stirring device is provided in the flocculation chamber 15. The stirring device includes a stirring blade 8, a stirring shaft 7, and a stirring motor 6, which are connected in sequence, and the stirring blade 8 includes a housing. And a hollow cavity, the shell is evenly distributed with outflow holes, the hollow cavity is used to fill the liquid flocculant, the flocculation chamber 15 and the metal capture chamber 2 are provided with a filter layer, and the metal capture chamber 2 It includes a nozzle arranged at the upper part of the metal trapping chamber 2 and a water outlet arranged at the lower part of the metal trapping chamber 2. The nozzle sprays a metal trapping agent into the metal trapping chamber 2, and the water outlet Connect with the water inlet of the centrifuge 3.
[0027] Among them, the sewage from the sewage discharge port of the finishing machine first enters the pH adjustment chamber 1 for pH adjustment, so that the heavy metal capture agent and the liquid flocculant react under the optimal pH condition, and the sewage passes through the pH adjustment chamber 1. Then enter the flocculation chamber 15, and at the same time start the stirring device, so that the liquid flocculant filled in the stirring blade 8 is evenly dispersed into the flocculation chamber 15 through the evenly distributed outflow holes, and the liquid flocculant and the sewage undergo a full flocculation reaction. After passing through the flocculation chamber 15 through the filter layer to remove flocculated impurities, then the sewage enters the metal trapping chamber 2 to react with the metal trapping agent to remove metal ions in the sewage, and then the sewage enters the centrifuge 3 for centrifugal treatment to remove the sewage And further remove residual suspended impurities, and then the sewage enters the biological oxidation chamber 4 for biological oxidation treatment to remove COD in the sewage and eliminate organic pollution in the sewage, so that the COD content in the sewage meets the national standard, and then the treated sewage Enter the circulating water tank 5 for storage.
[0028] The stirring device in the present invention adopts the hollow structure of the stirring blade 8 and the outflow holes are evenly distributed on the stirring blade 8, so that the liquid flocculant filled in the stirring blade 8 can be evenly dispersed in the flocculation chamber 15, improving Flocculation effect.
[0029] Similarly, in order to further optimize the structure, the hollow cavity of the stirring blade 8 in the present invention can also be connected with a liquid flocculant supply device to avoid the problem of insufficient liquid flocculant supply during the working process. In order to make the flocculation reaction in the flocculation chamber 15 more fully and to ensure the normal progress of sewage treatment, the stirring blade 8 in the present invention is arranged at the bottom of the flocculation chamber 15, so that the flocs produced by the flocculation reaction will not settle and accumulate and avoid flocs The occurrence of blocking the filter layer ensures the normal progress of sewage treatment.
[0030] In order to simplify the structure and reduce the overall volume of the sewage treatment device of the light decorating machine, the flocculation chamber 15 and the metal collection chamber 2 in the present invention are an integral structure.
[0031] The filter layer in the present invention includes a quartz sand filter layer 14 and an activated carbon adsorption layer 13 arranged from top to bottom, so that the sewage after the flocculation reaction enters the metal collection chamber 2 after double-layer filtration, which improves the filtration of the sewage effect.
[0032] In the present invention, the biological oxidation chamber 4 includes a biological filler fluid layer 9, a water distribution layer 10, a biological filler fixed layer 11, and a water outlet layer 12 arranged from top to bottom; the biological filler fluid layer 9 floating in the microbe-attached filler The bio-oxidation chamber 4 moves freely in the mixed liquid, and the constantly updated and sufficient biological interface makes the contact surface between the sewage and the biological filler constantly change, so as to achieve a better sewage treatment effect. The biological filler set in the lower part of the biological oxidation chamber 4 The fixed layer 11 is not only a carrier of the biofilm, but also has the function of intercepting suspended substances, which improves the quality of the treated water.
[0033] In order to make the sewage and the biofilm on the filler frequently contact, a drain valve and an aerator are also provided in the water outlet layer 12 in the present invention. Relying on the stirring effect of aeration, the sewage is in a flowing state and the filler is in a flowing state. The air bubbles are cut in the middle to make the air distribution more uniform, improve the utilization rate of oxygen, and make the oxidation more thorough.
