Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people;

[0003] Common sewage often contains solid substances. In order to ensure the discharge quality, it is often necessary to separate the solid materials from the liquid sewage.

[0041] The output end of the sludge tank 2 is connected to a feed pipe 15, the output end of the sewage chamber 7 is connected to a water outlet pipe 16, the water outlet pipe 16 is located inside the feed pipe 15, and the output end of the water outlet pipe 16 is connected to a treatment box 17;

[0042] A plurality of water filter plates 18 are vertically installed at the bottom of the treatment box 17. The water filter plates 18 divide the bottom of the treatment box 17 into a plurality of treatment pools 19. An aeration pipe 20 and a heating pipe 21 are installed inside the treatment box 17. The aeration pipe 20 is located at the lower side of the heating pipe 21. A high-pressure air pump is installed at the input end of the aeration pipe 20. An electric heating device is installed at the input end of the heating pipe 21. A mixing chamber 22 is installed on the upper side of the water filter plate 18 inside the treatment box 17. A plurality of one-way air valves 23 are installed at the bottom of the mixing chamber 22. An ozone generator is installed at the input end of the mixing chamber 22. A condenser 24 connected to the input end and the output end of the mixing chamber 22 is installed inside the treatment box 17. The treatment box 17 is provided with a rough treatment drainage pipe 25 and a fine treatment drainage pipe 26.

[0043] A solid-liquid separation sewage treatment method comprises the following steps:

[0044] S1. Drain the sewage vertically downward from the top of the feed port 3 to the centrifugal drum 6, start the motor 9 to drive the centrifugal drum 6 to rotate, and under the action of centrifugal force, the solid impurities are lifted by the rotating spiral belt trough 10 and thrown into the sludge tank 2, and then discharged from the discharge pipe 15, and the liquid sewage enters the sewage cavity 7 after being screened by the filter water hole 8, and then discharged from the outlet pipe 16 into the treatment box 17. During centrifugation, the brush 13 contacts the outer wall of the centrifugal drum 6;

[0045] S2. Determine whether to use primary treatment or fine treatment according to the sewage input;

[0046] S3, when only primary treatment of sewage is required, fillers for sewage treatment are added to two adjacent filter plates 18, and then a high-pressure air pump is started for aeration treatment, and the treated sewage is collected at the output end of the rough treatment drainage pipe 25;

[0047] S4. When the sewage needs to be finely treated, close the rough treatment drain pipe 25, add fillers for sewage treatment in two adjacent filter plates 18, start the high-pressure air pump for aeration treatment, start the electric heating device to heat the heating tube 21, and then heat the sewage inside the treatment box 17 to become gaseous, enter the mixing chamber 22 through the one-way air valve 23, start the ozone generator to purify the gaseous sewage with ozone, and then start the condenser 24 to condense the gaseous sewage mixed with ozone into liquid, and collect the treated sewage at the output end of the fine treatment drain pipe 26.

[0048] In this embodiment, sewage enters the centrifugal drum 6 vertically downward from just above the feed port 3, and the starting motor 9 drives the centrifugal drum 6 to rotate. The rotation of the centrifugal drum 6 will not drive the sewage tank 5 fixed by the support foot 4 to rotate, and will not drive the outlet pipe 16 to move, and the outlet pipe 16 is also limited by the position of the discharge pipe 15, and under the reaction force, it also plays a role in fixing the position of the sewage tank 5. During the rotation of the centrifugal drum 6, under the effect of centrifugal force, the sewage will enter the sewage cavity 7 through the filter water hole 8, and the solid impurities in the sewage will be blocked and attached to the inner wall of the centrifugal drum 6. However, because the rotation of the centrifugal drum 6 will drive the spiral belt trough 10 to rotate, the solid matter will be driven by the spiral belt trough 10 to move upward until it moves out of the centrifugal drum 6 and is thrown into the outer sludge tank 2 under the centrifugal force, so as to achieve the purpose of solid-liquid separation; the sewage is discharged from the outlet pipe 16, and the solid matter is discharged from the discharge pipe 15 and collected under its own weight and the shaking of the equipment operation;

[0049] During the rotation of the centrifugal drum 6, the bristles on the brush body 12 installed in the slot 11 clear the water filter hole 8, thereby preventing impurities from blocking the water filter hole 8;

[0050] The liquid wastewater after solid-liquid separation is discharged from the outlet pipe 16 into the treatment box 17 for treatment. At this time, the relevant technicians can choose whether to perform primary treatment or fine treatment according to the source of the wastewater initially discharged into the centrifugal drum 6;

[0051] The primary treatment method is to add fillers for sewage treatment into two adjacent filter plates 18 in the treatment box 17, the fillers include but are not limited to activated carbon, biofilm, polymer and ceramic, and then start the high-pressure air pump to aerate the aeration pipe 20, so that the sewage can fully contact with various fillers and react and purify, and then the treated sewage can be collected at the output end of the rough treatment drainage pipe 25. Further, if aeration is not performed, the sewage discharged only after filtering by the fillers can meet the qualified discharge requirements, and aeration can be omitted to further save power resources;

[0052] The fine treatment method is to close the rough treatment drain pipe 25, add fillers for sewage treatment in two adjacent filter plates 18 in the treatment box 17, the fillers include but are not limited to activated carbon, biofilm, polymer and ceramic, then start the high-pressure air pump to aerate the aeration pipe 20, so that the sewage can fully contact with various fillers and react and purify, start the electric heating device to heat the heating pipe 21, and then heat the sewage inside the treatment box 17 to become gaseous, and the expansion of the gas will inevitably pass through the one-way air valve 23 into the mixing chamber 22, start the ozone generator, the ozone generator includes but is not limited to the HY-004-3A model, the ozone generated by the ozone generator is mixed with the gaseous sewage to achieve the purpose of ozone purification, and then start the condenser 24 to condense the flowing sewage mixed with ozone into liquid, and then take the treated sewage from the output end of the fine treatment drain pipe 26 connected to the output end of the condenser. It should be noted that the process of converting the liquid state of sewage into gaseous state and the gaseous state into liquid state can also play a role in the treatment of sewage.
