Description

Technical Field

[0001] This utility model relates to the field of chemical waste liquid treatment technology, specifically to a chemical waste liquid recycling and treatment device. Background Technology

[0002] Chemical waste liquid refers to the wastewater produced during the production process of chemical plants. After biochemical treatment, it can generally meet the national secondary discharge standard. However, due to the shortage of water resources, the water that meets the discharge standard needs to undergo further deep treatment to meet the requirements for industrial water replenishment and recycling.

[0003] Current methods for classifying and treating chemical wastewater generally employ sedimentation separation. This involves adding chemical agents to the wastewater for reaction and neutralization, followed by sedimentation and filtration to meet discharge requirements before discharge. During the chemical reaction and neutralization process, the wastewater typically requires agitation to achieve rapid and thorough treatment. Currently, most agitation devices are motor-driven, resulting in high costs and energy consumption. Furthermore, the wastewater recovery and treatment equipment often suffers from poor structural design, with the sedimentation and filtration zones located in the same unit—the reaction zone at the bottom and the filtration zone at the top. Because the upper zone contains more suspended particles, the filter requires frequent cleaning or replacement, leading to high initial investment costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a chemical waste liquid recycling and treatment device.

[0006] Furthermore, one end of the pipe is connected to the bottom of the drainage chamber, and the other end of the pipe is connected to the lower part of the filter tank. A mesh frame is fixedly connected to the middle of the inner side of the filter tank, and an activated carbon layer is provided on the mesh frame.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Example 1, in conjunction with Appendix Figure 1-5 A chemical waste liquid recycling and treatment device includes a treatment sedimentation tank 1 and a filter tank 2, with a pipe 3 connecting the treatment sedimentation tank 1 and the filter tank 2. The lower part of the treatment sedimentation tank 1 has a conical bucket section 4, and the bottom end of the conical bucket section 4 has a drain outlet connected to a drain pipe 5. A shut-off valve is installed on the drain pipe 5. The lower part of the treatment sedimentation tank 1 has a water inlet pipe 6, one end of which extends from inside the treatment sedimentation tank 1 and is sealed and fixedly connected to the treatment sedimentation tank 1. The other end of the water inlet pipe 6... The inlet pipe 6 is vertically upward and located in the middle of the sedimentation tank 1. The vertically upward end of the inlet pipe 6 is connected to the shaft pipe 7 through a sealed rotary joint. The upper end of the shaft pipe 7 is sealed, and the upper part is uniformly provided with stirring pipes 8 along the circumference. Multiple water outlet holes 9 are uniformly provided along the circumference on one side of the stirring pipe 8. The axis of the water outlet holes is horizontal and passes through the axis of the stirring pipe 8. The end of the stirring pipe 8 away from the shaft pipe 7 is sealed. A drainage chamber 10 is provided on one side of the upper part of the sedimentation tank 1. An outlet 11 is provided between the sedimentation tank 1 and the drainage chamber 10.

[0022] In practice, the inlet pipe 6 is connected to an external inlet pipe. Waste liquid enters through the inlet pipe 6 and flows out through the stirring pipe 8. When the waste liquid is sprayed out, it will give the inlet pipe 6 a reaction force, which will cause the stirring pipe 8 to rotate slowly along the shaft pipe 7, so as to achieve the purpose of discharging waste liquid at different positions and stirring the waste liquid. Chemical agents and flocculants are added to the treatment sedimentation tank 1 to achieve full mixing of chemical agents and waste liquid. The suspended particles in the waste liquid aggregate and become larger or form flocs, thereby accelerating the sedimentation of particles and achieving the purpose of solid-liquid separation. The settled material is discharged through the sewage pipe 5. The wastewater from the first treatment enters the filter tank 2 through the outlet 11, the drainage chamber 10, and the pipe 3, and is discharged after further filtration.

[0023] In this specific embodiment, one end of the pipe 3 is connected to the bottom of the drainage chamber 10, and the other end of the pipe 3 is connected to the lower part of the filter tank 2. A mesh frame 12 is fixedly connected to the middle of the inner side of the filter tank 2. An activated carbon layer 13 is provided on the mesh frame 12. An outlet and an overflow outlet are provided at the upper part of the filter tank 2. The outlet is located below the overflow outlet. The outlet is connected to an outlet pipe 14, and the overflow outlet is connected to an overflow pipe 15. The treated waste liquid is filtered through the activated carbon layer 13 and then discharged from the outlet pipe 14.

[0024] In this specific embodiment, the pipe 3 is provided with a U-shaped section 16, and a shut-off valve 2 is provided on the bottom side of the U-shaped section. The shut-off valve can be opened periodically to clean the particulate matter that has settled here.

[0025] In this specific embodiment, the filter tank 2 is provided with a rinsing port at the bottom, and the rinsing port is provided with an end cover 17. The end cover is opened periodically to clean the bottom of the filter tank 2.
