As the injected sewage increases, the sewage will overflow the 10-mesh filter screen 44. At this time, the particle pollutants with a diameter larger than 44 grids of the 10-mesh filter screen will remain in the space below the filter screen. The sewage continues to be pumped in, and the sewage will overflow the 50-mesh filter screen 42. At this time, the particle pollutants with a diameter larger than 42 grids of the 50-mesh filter screen will remain in the space below the filter screen. The sewage continues to be pumped in, and the sewage will overflow the 80-mesh filter screen 40. At this time, the particle pollutants with a diameter larger than 40 grids of the 80-mesh filter screen will remain in the space below the filter screen. The sewage continues to be pumped in, and the sewage will overflow the 10-mesh filter screen 44. At this time, the particle pollutants with a diameter larger than 44 grids of the 10-mesh filter screen will remain in the space below the filter screen. The particulate matter filtered by multiple layers will slowly settle at the bottom of the first shell 37. The sewage that has been preliminarily filtered flows into the secondary filter device body 30 through the upper water pipe 20 of the primary filter device 21, passes through the third water leakage baffle 66, is adsorbed and filtered by the filter brush 49, and then flows through the oil-absorbing cotton.

The sewage passes through the oil-absorbing cotton and passes through the first water leakage baffle 51 under the oil-filtering cotton 50 to enter the UV lamp 53 sterilization and disinfection area to remove bacteria and organic matter in the sewage. The sewage continues to flow through the filter cotton 54, passes through the water leakage baffle under the filter cotton 54, enters the bottom of the secondary filter device body 30, passes through the secondary filter outlet pipe 67 at the bottom of the secondary filter device body 30, and flows into the storage tank 34 through the second sewage discharge pipe 68 for collection.

During this process, pollutant molecules in the sewage are filtered out and remain in the bottom space of the first filter body 022, where they continue to accumulate. As the amount of sewage injected gradually increases, the filtered water is discharged from the first filter body's outlet hole 062. After being discharged from the first filter body 022, the filtered water flows through a pipe into the second filter body's inlet hole 065, and then passes through the second filter body 024 for further filtration. Within the second filter body 024, the filtered sewage fills the bottom space and continues to spread upward, passing through the fourth leaking baffle 045, second-grade C filter cotton 044, second-grade B filter cotton 043, second-grade A filter cotton 042, and third leaking baffle 041. During this process, pollutant molecules in the sewage are filtered out and remain in the bottom space of the second filter body 024, where they continue to accumulate.

After the above series of treatment processes, the water has met the standards for reuse in the car wash machine. When cleaning the sediment in the primary filter device: close the second water inlet switch valve 053 and the third sewage discharge switch valve 058 of the secondary filter device body 024, open the fourth switch valve 070 of the sewage discharge hole 064 of the primary filter device, connect clean water to the main water inlet connection port 58, press the second cleaning button 013, and inject pressurized clean water to flush the bottom sediment, and the filter residue will be discharged from the sewage discharge hole 064 of the primary filter device. When cleaning the sediment in the secondary filter device: close the first switch valve 051 and the fourth switch valve 070 of the primary filter device body 022, open the third switch valve 058 at the sewage discharge hole 066 of the secondary filter device, connect clean water to the main water inlet connection port 58, press the second cleaning button 013, and inject pressurized clean water to flush the bottom sediment, and the filter residue will be discharged from the sewage discharge hole 066 of the secondary filter device; When inspecting a single module: drain the water in the equipment, close all the on-off valves, unscrew the third joint 059 on the left end of the pre-filter 052, unscrew the fourth joint 071, unscrew the first joint 055, unscrew the second joint 057, and then remove the primary filter body 022 and the secondary filter body 024 separately; After being treated, it is further treated by the tap water purification system. At this time, the first operation button 103 is pressed, and the car wash sewage enters the sewage treatment equipment from the first water inlet joint 114, and is preliminarily filtered through the Y-type filter 217 and the pre-purification filter 207. The preliminary filtration can filter out large suspended solids in the water; then it is pressurized by the first booster pump 219 and enters the catalytic oxidation sterilization treatment box 203. The catalytic oxidation sterilization treatment box 203 is equipped with a sterilization lamp and a catalytic oxidation catalyst to sterilize and degrade organic matter; after catalytic oxidation sterilization, it enters the flocculation sedimentation tank 212 through the first one-way valve 210. The first one-way valve 210 can prevent sewage from flowing back and prevent the agent from flowing into the pretreatment process. The flocculant in the liquid flocculant storage box 202 is added to the flocculation sedimentation tank 212 through the dosing pump 201 for flocculation sedimentation. The flocculation sedimentation can remove turbidity, decolorization, deoiling, and degreasing. Water, deodorization, and heavy metal removal; after flocculation and sedimentation, it enters the pH neutralization water treatment tank 213 through the first one-way valve 210. The first one-way valve 210 can prevent sewage from flowing back and prevent the chemical from flowing into the pre-treatment process. The pH regulator in the pH regulator storage box 208 is added to the pH neutralization water treatment tank 213 through the dosing pump 201 for pH neutralization. pH neutralization can adjust the pH value of the sewage to the tap water standard; after pH neutralization, the sewage enters the sewage filter 215 through the pipeline for fine filtration. The sewage filter 215 can filter tiny particles in the water and has an adsorption function. It can remove tiny suspended matter, remove residual chlorine, and further remove color and odor in the water. After the sewage passes through the sewage filter 215, the water quality can reach the tap water standard; the water treated by the sewage filter 215 enters the storage tank 205 through the pipeline for temporary storage.

At this time, press the second operation button 309 again, and the tap water is connected to the sewage treatment equipment from the second water inlet joint 312. The sewage enters from the water inlet pipe 408, passes through the ball valve switch 501, and then passes through the Y-type impurity filter 502 and the pre-impurity filter 503 for preliminary filtration. The preliminary filtration can filter out large suspended matter in the water, and then enters the No. 1 impurity filter 403 after being pressurized by the second booster pump 402. The No. 1 impurity filter 403 It has the function of filtering and adsorbing heavy ions, and can filter heavy metal ions in the water. After passing through the No. 1 impurity filter 403, it enters the No. 2 impurity filter 404. The No. 2 impurity filter 404 is an RO membrane filter element with very small gaps, which can filter most of the ions and bacteria in the water, so that the filtered water quality can meet the standard of drinking water. The water treated by the No. 2 impurity filter 404 enters the water storage tank 406 through a pipe for temporary storage. When needed, open the drinking water outlet 302 for use, so that the equipment can use the preliminary sewage treatment system and the circulating sewage treatment system in sequence. After the car wash sewage is treated, the effluent water can meet the recycling standard and can continue to be used for car washing, thereby improving the utilization rate of water resources. In addition, the preliminary sewage treatment system, the circulating sewage treatment system and the tap water purification treatment system are used in sequence. After the car wash sewage is treated, the effluent water can meet the tap water standard. In addition to washing cars, it can also be used for washing vegetables and boiling water, thereby achieving the purpose of water resource regeneration.
