[0023] Embodiment 1

[0024] See also Figure 1-4 As shown, the utility model provides a technical solution: a wastewater treatment device for coating production, comprising a sedimentation tank 1 and a treatment mechanism 2, wherein the treatment mechanism 2 is arranged outside the sedimentation tank 1;

[0025] The processing mechanism 2 includes a water diversion component 21, a separation component 22, a filtering component 23, a pressing component 24 and a purification component 25. The water diversion component 21 is arranged on the outside of the sedimentation tank 1, the separation component 22 is arranged on one side of the sedimentation tank 1, the filtering component 23 is arranged on the inner wall of the sedimentation tank 1, the pressing component 24 is arranged on the other side of the sedimentation tank 1, and the purification component 25 is arranged on one side of the filtering component 23.

[0026] Furthermore, the water diversion assembly 21 includes a water inlet pipe 211 and a valve 212. The water inlet pipe 211 is welded to the outside of the sedimentation tank 1. The top of the water inlet pipe 211 is provided with a valve 212. The sewage to be treated is guided to the sedimentation tank 1 through the water diversion assembly 21.

[0027] Furthermore, the separation component 22 includes an agitator 221, a dosing tank 222 and a drug outlet 223. The agitator 221 is fixedly connected to both sides of the inner wall of the sedimentation tank 1, and the dosing tank 222 is symmetrically arranged on one side of the sedimentation tank 1. The top of the dosing tank 222 is fixedly connected to the drug outlet 223. The separation component 22 flocculates the sewage, and adds flocculants through the dosing tank 222 to aggregate tiny particles suspended in the water into larger flocs for easy sedimentation and separation. During the sedimentation process, the sludge settles to the bottom to form a precipitate, while the clean water remains in the upper layer, which is called supernatant. This separation process helps to purify the water quality.

[0028] Furthermore, the filter assembly 23 includes a first water pipe 231, a filter cartridge 232, a second water pipe 233 and a water pump 234. The first water pipe 231 is fixedly connected to one side of the inner wall of the sedimentation tank 1, the other end of the first water pipe 231 is bolted to the filter cartridge 232, the other end of the filter cartridge 232 is bolted to the second water pipe 233, and a water pump 234 is arranged at the top of the second water pipe 233. The filter assembly 23 is designed to pump the pretreated supernatant to the reaction tank 251 for secondary purification. The filter cartridge 232 can effectively remove suspended particles and tiny pollutants, thereby improving the purity of the supernatant.

[0029] Furthermore, the pressing component 24 includes a sludge extractor 241, a filter press 242, a faucet 243 and an outlet pipe 244. The sludge extractor 241 is welded on the other side of the sedimentation tank 1. The bottom end of the sludge extractor 241 is fixedly connected to the filter press 242. The outer side of the filter press 242 is threadedly connected to the faucet 243. The outer side of the faucet 243 is sleeved with an outlet pipe 244. The precipitated sludge is squeezed by the pressing component 24 to squeeze out the remaining sewage. Then, this part of the squeezed sewage is purified and finally discharged through the outlet pipe 244, which effectively separates the residual water in the sludge, reduces the water content, and makes subsequent treatment more efficient.

[0030] Furthermore, the purification component 25 includes a reaction tank 251, a microorganism breeding device 252, a drain pipe 253 and a switch 254.

The purification component 25 performs secondary purification on the supernatant to ensure that it meets the water quality requirements that meet the emission standards. Through this step, the residual tiny particles and organic matter can be further removed, and the purity of the supernatant can be further improved.

[0031] Embodiment 2

[0032] See also Figure 1 and Figure 2 As shown, in comparison with Example 1, as another implementation mode of the utility model, a control component 3 is arranged on the outside of the reaction tank 251, and the control component 3 includes a workbench 31 and a water quality detection sensor 32. The outside of the reaction tank 251 is fixedly connected with the workbench 31, and the outside of the microorganism breeding device 252 is symmetrically provided with water quality detection sensors 32. The entire device is operated and controlled by the control component 3, wherein the water quality detection sensor 32 is responsible for detecting the water quality to ensure that it meets the requirements and reaches the emission standards.

[0033] Working principle: First, a wastewater treatment device for coating production is moved to the working position. When in use, the first step is to open the valve 212 to introduce the wastewater into the sedimentation tank 1, and then the dosing tank 222 uses the treatment liquid through the outlet 223 to flocculate the wastewater in the sedimentation tank 1. After the wastewater is flocculated, the sludge is deposited to the bottom to form sediment, and the clean water is left in the upper layer, which is called supernatant. The second step is to start the pump 234 through the control component 3 to collect the supernatant in the sedimentation tank 1. The supernatant is provided with a filter cartridge 232 in the process of passing through the first water pipe 231 and the second water pipe 233 for filtering treatment. The filtered supernatant is pumped to the reaction tank 251. The third step is to collect the sediment. The sludge deposited at the bottom is extracted into the filter press 242 by the sludge extractor 241. Clean water is extracted from the sludge through the squeezing process of the filter press 242. The clean water flows into the outlet pipe 244 through the faucet 243. In the fourth step, the clean water is pumped to the first water pipe 231 through the water pump 234 for filtration and then pumped to the reaction tank 251 through the second water pipe 233. In the fifth step, the supernatant pumped into the reaction tank 251 is biologically purified by the microorganisms in the microbial breeding device 252. When the water quality detection sensor 32 detects that the water quality is qualified and meets the discharge standard, the supernatant is discharged through the drain pipe 253. In this way, the use process of a wastewater treatment device for paint production is completed.
