Problems solved by technology

[0002] With the advancement of science and technology, a large amount of wastewater is produced in the process of industrial production, which has caused the problem of heavy metal pollution in my country's water to be very prominent, and sewage treatment is urgent. However, traditional metal-polluted sewage treatment devices mostly use a single treatment method to treat sewage. The effect is not good, it cannot meet the national discharge standards, and the treatment process is relatively cumbersome. The chemical sedimentation method used in the sewage treatment process needs to chemically settle the additives in the sewage, but the traditional mixing device is prone to reaction dead zones. The sedimentation reaction is not complete, and the sediment is not easy to remove. When using electrolysis to remove heavy metals, it is necessary to continuously remove the foam generated by electrolysis. However, the existing foam removal device uses a net structure to salvage the foam. This process will make the sewage fluctuate greatly, causing the froth to mix into the sewage again, reducing the treatment efficiency

Embodiment 1

[0051] Such as Figure 2-Figure 10 As shown, the present invention provides a water treatment system with a heavy metal removal mechanism, including a base 100, an adsorption filter mechanism 200, a reaction mechanism 300, an electrolysis mechanism 400 and a suction mechanism 500;

[0052] Wherein, the adsorption filter mechanism 200 is used to adsorb and filter the impurities of larger particles in the sewage. The adsorption filter mechanism 200 is composed of an adsorption box 201 and an adsorption assembly. The adsorption box 201 is arranged above the base 100 through a bracket 101. It can be detachably installed in the adsorption box 201;

[0053] The adsorption assembly is composed of two support plates 202, quartz sand filter layer 203, activated carbon adsorption layer 204 and filter cloth 205. The quartz sand filter layer 203, activated carbon adsorption layer 204 and filter cloth 205 are arranged on the two support plates in sequence from top to bottom. 202, the top ...

Embodiment 2

[0072] Such as figure 1 As shown, a kind of water treatment method with heavy metal removal mechanism provided by the present invention uses the above-mentioned water treatment system with heavy metal removal mechanism to treat sewage, specifically comprising the following steps:

[0073] S1. Lead the sewage into the adsorption filter mechanism 200 to absorb and filter the large particles of impurities in the sewage through the adsorption component;

[0074]S2. Introduce the filtered sewage into the electrolytic tank 401 through the primary delivery pump 601. When the liquid level reaches the set value, the PLC controller controls the primary delivery pump 601 to close, and at the same time controls the drug delivery valve 702 to open, and the quantitative reaction Add the medicine into the reaction box 301, then start the rotating shaft of the stirring motor 302 and the rotating shaft of the delivery motor 305 to rotate clockwise, and then quickly and fully stir the sewage in...

Abstract

The invention discloses a water treatment system with a heavy metal removal mechanism. The water treatment system comprises a base, and an adsorption filtering mechanism, a reaction mechanism, an electrolysis mechanism and a suction mechanism are sequentially arranged on the base. According to the water treatment system with the heavy metal removal mechanism provided by the invention, the adsorption mechanism and the reaction mechanism are matched with the electrolysis mechanism to realize multi-stage treatment of sewage containing heavy metals, and compared with a traditional single water treatment mode, the water treatment effect is improved, the treatment efficiency is improved, and the water treatment cost is reduced. Through the arrangement of the suction mechanism and a medicine storage tank, the functions of automatic quantitative medicine adding and automatic floating foam suction are achieved in cooperation with a PLC, manpower consumption is reduced, the treatment efficiency is improved, and large fluctuation cannot be generated on sewage during floating foam suction; and through the arrangement of a stirring assembly in cooperation with a discharging assembly, sewage and reaction agents in a reaction tank are rapidly and fully stirred, the phenomenon of dead zones is avoided, and the reaction speed is increased.
