Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a wastewater treatment device for EPE plastic processing. Background Technology

[0002] With the development of society, EPE (pearl cotton) plastic has been widely used in many fields such as packaging, construction, and home furnishing due to its good cushioning, heat insulation, and moisture-proof properties. The processing of EPE plastic will generate wastewater. If this wastewater is discharged directly without proper treatment, it will pollute the environment, affect the ecological balance of water bodies, and may also lead to soil pollution and other problems.

[0003] However, existing wastewater treatment methods for EPE plastic processing often rely on simplified processes adopted by some companies to reduce costs and streamline procedures. These methods involve only a single, basic treatment, which presents numerous problems. For example, they fail to effectively remove complex pollutants such as residual organic matter and heavy metal ions, making it difficult to meet discharge standards. Furthermore, they do not adequately eliminate microorganisms in the wastewater, potentially leading to their proliferation and damage to the ecosystem. Additionally, the water quality after this simple treatment is unstable, making reuse difficult and hindering the effective recycling of water resources. Utility Model Content

The belt groove one is opened at the top of the drive shaft one, the belt groove two is opened at the top of the drive shaft two, the drive motor is fixedly installed on the top of the sealing cover, and the drive belt is sleeved between the belt groove one and the belt groove two.

[0014] By adopting the above technical solution, the drive motor drives the drive shaft one and drive shaft two to rotate through the drive belt, so as to realize the function of stirring the wastewater in the stirring block in the treatment tank one and stirring the wastewater in the paddle in the treatment tank two, so that the wastewater and the treatment agent are fully mixed and reacted.

[0015] As a further description of the above technical solution: the top of the base has two support grooves, and processing barrel one and processing barrel two are located in the corresponding support grooves in sequence. The top of the base is fixedly connected with four baffles, and the front and rear sides of the outer walls of processing barrel one and processing barrel two are provided with baffles.

[0018] 1. Compared with existing technologies, this EPE plastic processing wastewater treatment device, by setting up a second injection pipe, a first drive shaft, and a stirring block, allows for the injection of a pH adjuster, such as sodium hydroxide solution or dilute sulfuric acid solution, into the first treatment tank through the second injection pipe. The pH value of the wastewater is selected according to its initial pH value to precisely adjust the acidity or alkalinity. Then, the first drive shaft drives the stirring block to rotate, so that the reagent and wastewater are fully mixed, thereby adjusting the pH value and ensuring that the acidity or alkalinity of the wastewater meets the requirements of subsequent treatment processes. This improves the overall treatment effect and ensures the smooth operation of each treatment stage.

[0019] 2. Compared with existing technologies, this EPE plastic processing wastewater treatment device, through the installation of an injection pipe, a drive shaft, and paddles, allows for the injection of chlorine dioxide disinfectant into the treatment tank through the injection pipe. Chlorine dioxide has strong oxidizing properties, which can effectively kill various microorganisms such as bacteria, viruses, and fungi in wastewater, with few disinfection byproducts. Then, the drive shaft drives the paddles to rotate, allowing the disinfectant to fully diffuse in the wastewater, achieving disinfection. This effectively kills bacteria and viruses in the wastewater, ensuring the safety of the effluent and preventing microorganisms from harming the environment. Attached Figure Description

[0032] Working principle: First, EPE plastic processing wastewater is injected into treatment tank 2 through water injection pipe 601. The wastewater first passes through the filter screen 801 on the inner wall of the inner cylinder 8 to intercept larger particles of impurities. Then, it enters the main body of treatment tank 2 through the filter hole 11 at the top of the inner cylinder 8. According to the initial pH value of the wastewater, if the wastewater is acidic, an appropriate amount of sodium hydroxide solution is injected into treatment tank 2 through liquid injection pipe 602; if the wastewater is alkaline, a dilute sulfuric acid solution is injected. Then, the drive motor 703 is started. The drive motor 703 drives the drive shaft 9 to rotate through the drive belt 704. The stirring block 10 on the drive shaft 9 rotates accordingly, so that the pH adjuster is fully mixed with the wastewater, and the pH value of the wastewater is adjusted to a suitable range to meet the requirements of subsequent treatment processes.

[0033] After pH adjustment, water pump 5 is started to transport the wastewater in treatment tank 2 to treatment tank 3 via transition water pipe 4. In treatment tank 3, a certain concentration of chlorine dioxide disinfectant is injected through injection pipe 301. Drive motor 703 continues to operate, driving drive shaft 12 via drive belt 704. The blades 13 on drive shaft 12 rotate, allowing the chlorine dioxide disinfectant to fully diffuse in the wastewater, utilizing its strong oxidizing properties to kill bacteria, viruses, fungi, and other microorganisms. Simultaneously, if necessary, heating pipe 16 can be turned on to heat the wastewater, assisting in disinfection or accelerating certain chemical reactions, further improving the wastewater treatment effect.

[0034] After the wastewater has undergone the above treatment and meets the discharge standards, it is discharged from the drain pipe 302.
