Technical Field

[0001] This utility model relates to the field of industrial wastewater purification technology, specifically to a purification and treatment device for industrial wastewater containing heavy metal ions. Background Technology

[0002] The heavy metal ion-containing industrial wastewater purification and treatment device is a special treatment equipment for wastewater containing heavy metal ions such as cadmium, lead, and mercury discharged from industrial production. It removes or converts the heavy metal ions in the wastewater into low-toxicity or non-toxic forms, so that the treated water quality meets the discharge standards or reuse requirements, thereby reducing the harm of heavy metals to the environment and human health, and realizing the harmless treatment and resource utilization of industrial wastewater.

[0003] If industrial wastewater containing heavy metal ions is discharged directly without effective treatment, it will cause serious pollution to soil and water bodies, endangering the ecological environment and human health. At present, common treatment methods such as chemical precipitation have problems such as high consumption of reagents and easy generation of sludge for secondary pollution, and the effect is not good when used. Therefore, it is necessary to improve it. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a purification treatment device for industrial wastewater containing heavy metal ions, comprising a pretreatment mechanism 1 and a purification mechanism 2, wherein the purification mechanism 2 is fixedly connected to the bottom of the pretreatment mechanism 1.

[0023] The purification mechanism 2 includes an adsorption unit and a circulation treatment unit. The adsorption unit is fixedly connected to the bottom of the pretreatment mechanism 1, and the circulation treatment unit is fixedly connected to the side of the adsorption unit.

[0024] The pretreatment mechanism 1 consists of a base plate 101, a support frame 102, a mixing tank 103, a motor 104, a mixing rack 105, and a discharge valve 106. The support frame 102 is fixedly connected to the top of the base plate 101, the mixing tank 103 is fixedly connected to the top of the support frame 102, the motor 104 is fixedly connected to the bottom of the mixing tank 103, the mixing rack 105 is rotatably connected to the top of the motor 104, and the discharge valve 106 is fixedly connected to the bottom of the mixing tank 103, which serves to add chemicals and stir for preliminary pretreatment.

[0025] The adsorption unit consists of a filter frame 201, a filter screen 202, a guide tube 203, a collection box 204, and a filter box 205. The filter frame 201 is fixedly connected to the bottom of the mixing tank 103. The filter screen 202 is fixedly connected to the inside of the filter frame 201 and is snapped into place inside the filter frame 201, making it easy to disassemble and clean the filtered impurities. The guide tube 203 is fixedly connected to the bottom of the filter frame 201, the collection box 204 is fixedly connected to the bottom of the guide tube 203, and the filter box 205 is fixedly connected to the top of the collection box 204. It serves to filter and adsorb water quality. The filter box 205 contains an adsorption filter element for easy adsorption. The circulation treatment unit consists of a top cover 201. 11. The system consists of a conduit 212, a return pipe 213, a discharge pipe 214, and a control valve 215. The top cover 211 is fixedly connected to the top of the filter box 205, and the conduit 212 is fixedly connected to the top of the top cover 211. A water quality detection device is installed inside the conduit 212, which is electrically connected to the control valve 215 to facilitate the detection of whether the water quality is qualified. If the water quality is qualified, the return pipe 213 will be closed; if the water quality is unqualified, the discharge pipe 214 will be closed, and the water will be returned for secondary treatment. The return pipe 213 is fixedly connected to the surface of the conduit 212, the discharge pipe 214 is fixedly connected to the surface of the conduit 212, and the control valve 215 is fixedly connected to the surfaces of the return pipe 213 and the discharge pipe 214, playing a role in circulation control treatment.

[0026] In operation, industrial wastewater containing heavy metal ions first enters the pretreatment unit 1. In the mixing tank 103, the motor 104 drives the mixing frame 105 to rotate, achieving chemical addition and mixing, completing the initial pretreatment. Then, the discharge valve 106 is opened, and the wastewater is filtered through the filter screen 202 in the filter frame 201, flows into the collection box 204 through the guide pipe 203, and then enters the filter box 205, where it undergoes deep adsorption treatment using the internal adsorption filter element. The treated wastewater enters the conduit 212 through the top cover 211. The water quality detection device in the conduit 212 monitors the water quality in real time and feeds the data back to the control valve 215. If the water quality is qualified, the control valve 215 closes the return pipe 213, and the wastewater is discharged through the discharge pipe 214. If the quality is not qualified, the control valve 215 closes the discharge pipe 214 and opens the return pipe 213, allowing the wastewater to flow back to the adsorption unit for secondary treatment. This cycle ensures that the effluent water quality meets the standards, and the filter screen 202 is clipped onto the filter frame 201 for easy cleaning of impurities.
