Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment and reuse, and in particular relates to a sewage treatment and reuse device and a sewage treatment and reuse method. Background Art

[0002] At present, there are four main methods for sewage treatment: 1. Physical treatment method, a sewage treatment method that separates and recovers insoluble suspended pollutants (including oil film and oil droplets) in wastewater through physical action. Generally, after primary treatment, the removal rate of suspended solids is 70% to 80%, while the removal rate of biochemical oxygen demand (BOD) is only about 25% to 40%, and the degree of wastewater purification is not high. 2. Chemical treatment method, a sewage treatment method that separates and removes pollutants in the form of dissolved and colloidal states in wastewater or converts them into harmless substances through chemical reactions and mass transfer. Chemical agents need to be added, which is costly, has a long reaction time, many procedures, and is relatively complicated. 3. Biological treatment method, a sewage treatment method that converts organic pollutants in the form of solutions, colloids, and fine suspensions in wastewater into stable and harmless substances through the metabolism of microorganisms. However, a digestion tank needs to be established, and the treatment equipment includes biological filters, biological turntables, biological contact oxidation tanks, and biological fluidized beds, etc., which requires a large amount of engineering work, high operating costs, and high daily maintenance costs. 4. Biological contact oxidation method, using biological contact oxidation method to treat sewage, that is, using biological contact oxidation process to fill fillers in the biological reaction pool, the oxygenated sewage immerses all the fillers, and flows through the fillers at a certain flow rate, the organic pollutants are removed, the sewage is purified, and finally, it is necessary to disinfect with chlorine before it can meet the discharge standards. And it is necessary to set fillers in the pool, aerate the bottom of the pool to oxygenate the sewage, and make the sewage in the pool body in a flowing state, so as to ensure that the sewage is fully in contact with the fillers immersed in the sewage, and avoid the defect of uneven contact between sewage and fillers in the biological contact oxidation pool. The above four methods are basically suitable for centralized treatment and suitable for large-volume treatment occasions. Although centralized treatment can centrally monitor the effect of sewage treatment, reduce secondary pollution, and is conducive to resource regeneration. However, it also increases the cost investment of sewage collection and engineering construction, and the blockage, leakage and environmental pollution in the sewage collection process are extremely common, the maintenance cost is high, and many people are required. Once urban waterlogging occurs, it cannot be discharged, causing serious environmental pollution, especially in rural areas or backward towns, where there is a lack of sewage treatment infrastructure, direct discharge is even more polluting, resulting in a poor living environment. Therefore, for households, hotels, restaurants, communities, villages, streets, government departments, enterprises and institutions with small sewage volumes, it is necessary to research and develop a device that can timely treat sewage on site. In addition, in view of the current global water shortage, it is even more necessary to promote water conservation.

[0055] The water inlet 303 of the filter basket is connected to the bottom of the sewage collection box 2, the first reduction motor 307 is fixed on the outside of the carbide collection box 7 with a cover, the output shaft of the first reduction motor 7 passes through the carbon circulation filter basket 301 and the conical cylinder screen 302 in sequence to connect the screen cleaning brush hanging ring 312, the filter basket scraper plate 308 and one end of multiple screen stirring brushes 309 are respectively connected to the output shaft of the first reduction motor 307 from left to right in sequence, the other end of the filter basket scraper plate 308 is close to the inner side of the carbon circulation filter basket 301, and the other ends of the multiple screen stirring brushes 309 are respectively close to the inner side of the conical cylinder screen 302, the two ends of the screen cleaning brush 310 are respectively fixed under the conical cylinder screen 302 through the screen cleaning brush hanging ring 311, and one end of the screen spring pulling piece 311 is fixed on the output shaft of the first reduction motor 307, and the other end is against the screen cleaning brush 310.

[0056] The filter basket scraper plate 308 scrapes the solid waste mixture into the carbonization treatment tube 4 through the filter basket discharge port 305 .

[0057] The purpose of the carbon circulation filter basket 301 is to achieve solid-liquid separation of sewage and solid waste mixture. Under the action of the scraper rake 308, the columnar activated carbon and solid waste are discharged from the filter basket discharge port 305 into the carbonization treatment pipe feed port 403.

[0058] The purpose of the conical cylinder screen 302 is to screen and separate the columnar activated carbon from the carbide particles.

[0064] The solid waste is carbonized at high temperature in the carbonization treatment tube 4 to form carbide particles, water and harmful smoke.

[0065] The carbide particles and the columnar activated carbon sterilized by high temperature are respectively discharged into the conical cylinder screen 2 through the carbonization tube discharge port 405, and the carbonization tube discharge port 405 is connected to the screen feed port 313. The second reduction motor 401 drives the screw propeller 402 to push the mixture of columnar activated carbon and solid waste to the carbonization tube discharge port 405, and discharge it into the conical cylinder screen 302 from the screen feed port 313. The first reduction motor 307 drives the screen stirring brush 309 to rotate continuously to separate the columnar activated carbon and the carbide particles, and push the columnar activated carbon back into the carbon circulation water filter basket 301 from the columnar carbon return basket port 304 to achieve the function of circulating water filtration. The conical cylinder screen 302 is respectively provided with a carbide particle recovery box 6 with a door.

[0066] The carbonization treatment tube 4 is tilted upward by 20 to 35 degrees, and one end of the carbonization tube discharge port 405 is higher than one end of the carbonization tube drain port 404. The filter box 5 is correspondingly arranged below the filter basket drain port 306 and the carbonization tube drain port 404.

The filter box 5 is provided with a filter net 501 at the top and a filter box drain pipe 502 at the bottom. The filter box drain pipe 502 is connected to the water inlet of the pump 11, and the water outlet of the pump 11 is connected to one end of the cold water tank inlet pipe 801, so that the water in the filter box 5 is pumped into the cold water tank 8 through the pump 11.

[0067] A filter screen is provided at the other end of the cold water tank inlet pipe 801 and is provided on one side of the top of the cold water tank 8. The cold water tank 8 is installed above the covered carbonization collection box 7. A cold water tank drain pipe 802 is provided on the other side of the top of the cold water tank 8. A ceramic heating rope 12 is wound around the carbonization treatment tube 4. The columnar activated carbon and solid waste in the carbonization treatment tube 4 are subjected to high-temperature carbonization treatment by the ceramic heating rope 12.

Columnar activated carbon is pre-installed at the bottom of the cold water tank 8, and a cold water tank drain pipe 803 is set at the bottom of the cold water tank 8. The cold water tank drain pipe 803 is connected to the sewage collection tank inlet pipe 201, which is convenient for cleaning and draining the cold water tank 8, and the generated sewage is directly collected and processed to prevent external discharge and waste. A drain valve 804 is set on the cold water tank drain pipe 803.

[0068] Since the density of water vapor is smaller than that of water, the distilled water tank 10 and the hot water tank 9 are respectively arranged in the cold water tank 8 from top to bottom, and the bottom of the hot water tank 9 is fixed in the cold water tank 8 through the footing 905. The distilled water tank 10 is provided with a distilled water tank water inlet pipe 1001, a distilled water tank overflow pipe 1002 and a distilled water tank drain pipe 1003.

[0070] The purpose of the annular heating tube 13 is to heat the water discharged into the tube through the high-temperature heat source generated by the ceramic heating rope 12. The annular heating tube 13 is mainly made of stainless steel thin tube material, which can be heated quickly. The annular heating tube can effectively increase the length of the water flow, ensure that there is enough time for heating, and effectively kill most of the microorganisms in the water in the heated annular tube 13. When the water volume reaches the rated pressure and the temperature reaches the preset water temperature, the temperature control valve 16 automatically opens to drain. At this time, the discharged water has been purified by multiple carbon filtration and high-temperature heating sterilization, and meets the discharge standard. After entering the hot water tank 9 for cooling, it can be used for flushing toilets, washing cars, watering flowers and grass, etc.; the water vapor entering the distilled water tank 10 is composed of pure water molecules, without microorganisms and any sediments, and there will be no odor to affect the water quality. It can meet the drinking water standard and can be used for washing hands, washing vegetables, washing clothes, taking a bath, drinking, etc.

[0071] The purpose of the ceramic heating rope 12 is to provide a heat source to quickly heat and sterilize the water in the annular heating pipe 13 at high temperature. When the water temperature reaches the preset temperature, the temperature control valve 16 automatically opens and discharges, and the hot water in the annular heating pipe 13 is discharged into the hot water tank 9 through the hot water pipe body 14 and the hot water tank inlet pipe 901. The hot water tank inlet pipe 901 is tilted upward by 45 degrees or 60 degrees, so that water vapor cannot enter the hot water tank inlet 901. Water vapor can only enter the distilled water tank 10 through the distilled water tank inlet 1001. The hot water that has not become water vapor flows into the hot water tank 9. The cold water in the cold water tank 8 can quickly cool the water in the hot water tank 9 and the distilled water tank 10 for daily use, thereby achieving the purpose of sewage reuse.

[0072] A large amount of harmful smoke will be generated during the high-temperature heating of sewage and solid waste through the carbonization treatment tube 4, and a large amount of smoke will be generated during the heating of water in the cold water tank 8 through the annular heating tube 13.

The water supply tank 1507 for the water filter provides a water source for the water filter 1501.

[0073] The purification method of the flue gas treatment system 15 is as follows: the first step is that the water in the water filter 1501 quickly cools the flue gas in the covered carbide collection box 7 to below 100°C, and filters some water-soluble substances; the second step is to use the characteristics of dioxin having a great affinity for fat-soluble substances, add animal oil or vegetable oil to the water in the water filter 1501, float on the water surface to form a second layer of filter net, and adsorb harmful gases such as dioxin. The third step is that the activated carbon in the activated carbon filter box 1502 effectively adsorbs harmful substances attached to water molecules and grease molecules. The fourth step is to remove dust with the dust bag 1503, and the flue gas is filtered again and discharged more cleanly. The flue gas purification system 15 adopts the patent number: 201920410234.1, and the invention name is "a kind of domestic waste disposer" in the flue gas purification system 15.

[0074] The sewage lift 1, the first reduction motor 307, the second reduction motor 401, and the water pump 11 are electrically connected to the electric control center respectively, and the electric control center controls their start and stop respectively.

[0076] like Figure 5 As shown, a shell 17 is installed on the sewage treatment and reuse device, and a pulley 18 is installed at the bottom of the shell 17 to realize the function of moving the sewage treatment and reuse device.

[0077] like Figure 4 As shown, the sewage treatment and reuse method using the sewage treatment and reuse device includes the following steps:

[0078] (1) Sewage and garbage are crushed by a sewage lifter 1 and sent to a sewage collection tank 2;

[0079] (2) The sewage and solid waste mixture in the sewage collection tank 2 is separated into solid and liquid by passing through a carbon circulation filter basket 301 pre-loaded with columnar activated carbon;

[0080] (3) The wastewater in step (2) is filtered through a carbon circulation filter basket 301 pre-loaded with columnar activated carbon and then discharged into a filter box 5 for secondary filtration and purification treatment;

[0081] (4) After the solid waste mixture and columnar activated carbon of step (2) are discharged into the carbonization treatment pipe 4 for high-temperature carbonization treatment, the solid waste mixture forms carbide particles, water and flue gas, and the generated water is discharged into the filter box 5 for secondary filtration and purification treatment; the carbide particles and the columnar activated carbon sterilized by high temperature are driven by the second reduction motor 401 to rotate the screw propeller 402, and are pushed into the conical cylinder screen 302, and the columnar activated carbon in the conical cylinder screen 302 is driven by the first reduction motor 307 to rotate the screen stirring brush 308, and is pushed back into the carbon circulation filter basket 301, and the carbide particles in the conical cylinder screen 302 are driven by the first reduction motor 307 to rotate the screen stirring brush 308, and are screened by the conical cylinder screen 302 into the carbide particle recovery box 6 with a door for recycling and reuse, and the flue gas generated during the high-temperature carbonization treatment is discharged from the exhaust pipe 701 into the flue gas purification system 15 for purification treatment to meet the emission standards;

[0082] (5) In step (4), the water in the filter box 5 is pumped to the cold water tank 8 by the pump 11 for three filtration and purification treatments, and then discharged into the annular heating pipe 13. The annular heating pipe 13 sterilizes the water discharged from the cold water tank 8 by the high-temperature heat source generated by the ceramic heating rope 12. When the water temperature in the annular heating pipe 13 reaches a preset temperature, the temperature control valve 16 automatically opens, and the hot water is discharged into the hot water tank 9, and the water vapor is discharged into the distilled water tank 10. The water in the hot water tank 9 and the distilled water tank 10 is cooled and reused.

[0083] Working principle:

[0084] The sewage lift 1 crushes the sewage and garbage in the public sewage pipe to form a mixture of sewage and solid garbage and transports it to the sewage collection box 2. The solid-liquid separation is carried out through the carbon circulation filter basket 301 pre-installed with columnar activated carbon. The first reduction motor 307 drives the filter basket scraper plate 308, the screen stirring brush 309 and the screen cleaning brush 310 to operate. The solid garbage and columnar activated carbon are continuously scraped by the filter basket scraper plate 308 into the carbonization treatment tube 4 for high-temperature carbonization treatment. After high-temperature carbonization, the solid garbage forms carbide particles, water and harmful smoke. The water is discharged into the filter box 5 for secondary filtration and purification treatment. The columnar activated carbon and carbide particles after high-temperature sterilization The screw propeller 402 driven by the second reduction motor 401 pushes and discharges the carbon into the conical cylinder screen 302. The screen stirring brush 309 rotates continuously under the drive of the first reduction motor 307 to push the columnar activated carbon after high-temperature sterilization back into the carbon circulation filter basket 301 from the columnar carbon return basket port 304 to achieve the effect of circulation filtration. The carbide particles are screened into the carbide particle recovery box 6 with a door through the conical cylinder screen 302 to achieve recycling. The screen cleaning brush 309 continuously swings back and forth to clean at the bottom of the conical cylinder screen 302 within the range of the spring toggle plate 311 and the limit range to prevent the screen holes from being blocked by carbide particles.

[0085] The sewage is filtered and separated by the carbon circulation filter basket 301 pre-loaded with columnar activated carbon and discharged into the filter box 5 for secondary filtration and purification. The pump 11 pumps the water in the filter box 5 to the cold water tank 8 for tertiary filtration and purification. The filtered and purified water in the cold water tank 8 is discharged into the annular heating pipe 13 through the cold water tank drain pipe 802 for high-temperature sterilization. When the water temperature in the annular heating pipe 13 reaches the preset temperature, the temperature control valve 16 automatically opens and discharges into the hot water tank 9 and the distilled water tank 10 respectively. After rapid heat dissipation and cooling through the cold water tank 8, the water in the hot water tank 9 is cooled and used for flushing toilets, washing cars, watering flowers and grass, etc.; the water vapor in the distilled water tank 10 is composed of pure water molecules, without microorganisms and any sediments, and can meet the drinking water standards, and can be used for washing hands, washing vegetables, washing clothes, taking a bath, drinking, etc.

[0086] In the process of rapid heating of the solid garbage and sewage mixture through the carbonization treatment tube 4 and the annular heating tube 13 respectively, a large amount of flue gas is generated in the covered carbonization collection box 7, and the flue gas is discharged into the filter tank 1501 through the exhaust pipe 701, so that the flue gas is quickly cooled down and some water-soluble substances are filtered. Taking advantage of the fact that dioxin has a great affinity for fat-soluble substances, animal oil or vegetable oil is added to the water in the water filter tank 1501, which floats on the water surface to form a second layer of filter net to adsorb harmful gases such as dioxin; the activated carbon in the activated carbon filter box 1502 effectively adsorbs harmful substances attached to water molecules and oil molecules, and then removes dust through the dust removal bag 1503, and after the flue gas is filtered and cleaned again, it is discharged from the chimney 1505 through the exhaust fan 1504 to meet the emission standards. The water filter tank 1506 provides water for the water filter tank 1501.

[0087] The models, specifications and dimensions of the various components of this specific embodiment are shown in Table 1:

[0088] Table 1:

[0089]

[0090] The sewage recycling device of the above specific embodiment can achieve the following technical effects:

[0091] 1. Ecological and environmental protection, people-oriented: First, sewage is purified by columnar activated carbon and sterilized by high-temperature heating. The flue gas is purified by the flue gas purification system and then discharged in compliance with the standards or heated to become water vapor, thus realizing water recycling. Second, solid garbage, excrement, etc. are crushed and carbonized at high temperature to become carbide particles, which are pollution-free and can be recycled. Third, the generated fume is filtered by water, oil, activated carbon and dust bag, and harmful gases such as dioxins are greatly reduced, meeting national emission standards. Fourth, columnar activated carbon is recycled to effectively block solid garbage and excrement and filter sewage.

[0092] 2. Save water: The device can filter and purify sewage for daily use, which is energy-saving and environmentally friendly.

[0093] For example, if the daily water consumption of a family of three is 50L, 18.25m3 of water can be saved in a year. 3 ; The calculation formula is: Annual water consumption (m 3 ) = daily water consumption (L) * 365 / 1000L.

[0094] Take the water consumption of public toilets in scenic spots as an example. If 100 people use a toilet seat every day, and the water capacity of the flush tank sold on the market is 3-6L, then based on the flush volume of 3-6L each time, 300-600L of water can be saved in a day, and 109.5-219m3 of water can be saved in a year. 3 The calculation method is: annual water consumption (m 3 ) = number of people using the toilet daily * water consumption per time (L) * 365 / 1000L.

[0095] 3. High sewage treatment efficiency: It can achieve immediate discharge and immediate treatment. Sewage enters the carbon cycle filter basket to separate solid waste and sewage. After filtration, purification, and high-temperature heating and sterilization, after meeting the discharge standards, part of the water flows into the hot water tank and can be used for flushing the toilet, etc.; the other part of the water becomes water vapor and enters the distilled water tank, which is cooled and condensed into distilled water, which can be used for washing hands, etc.; the length of the annular heating pipe is 40m. Calculated at a water flow rate of 1m / s, the time for sewage to pass through the annular heating pipe for high-temperature sterilization is 40s.

[0096] 4. Large sewage treatment capacity: The device not only has high sewage treatment efficiency, but also can treat large sewage capacity. According to the usual household toilet flush tank capacity of 3-6L and water flow rate of 1m / s, the water flow rate of a DN15 stainless steel annular heating tube is 0.177L / s, and the hourly sewage treatment capacity is 637.5L / h. Therefore, the daily sewage treatment capacity is 15.3m 3 The calculation formula is: daily sewage treatment volume = hourly sewage treatment volume * 24h.

[0097] 5. Strong practicability and wide applicability: It is suitable for places with large population and high mobility, such as residential areas, urban streets, rural families, administrative agencies, enterprises and institutions, large families, villas, parks and squares, tourist attractions, scenic spots; and places with severe water shortages such as deserts and plateaus are even more in need. Moreover, airplanes, ships, buses, large and small passenger cars, tourist RVs, etc. can also be designed and installed with toilets according to actual needs, because they can be installed and used as long as there is sewage discharge and electricity.

[0098] 6. Easy operation and maintenance, easy disassembly and assembly: you only need to connect and disassemble the sewage treatment and reuse device to the public sewage pipe, and start sewage and garbage treatment when the power is turned on; if there is a fault, it is convenient to replace parts or repair at any time.

[0099] 7. Save labor costs: For example, cleaning public toilets requires regular manual extraction, cleaning, loading, transporting, and processing of garbage from septic tanks. The workload is large, there are many people, the labor intensity is high, and it is very hard. However, the invented product can save the tedious processes of manual extraction, cleaning, loading, transporting, and processing of feces, and also suffer from the torment of odor. After the first water is added to the cold water tank, there is no need to add water in the future. It can be used continuously. When the water supply tank is full, it can also be used to water flowers and grass, etc. Kitchen waste, excrement, etc. are crushed and carbonized together with columnar activated carbon to become carbide particles. After being screened out, they are easy to recycle and can be made into carbon balls for reuse. Urban domestic sewage treatment is a major project. It needs to be collected and transported to sewage treatment plants for centralized treatment, which is time-consuming and labor-intensive, and the cost is high. The current market price is 1.2-1.5 yuan / m 3 The sewage treatment and reuse device of the present invention can realize on-site discharge and treatment, and can treat the sewage well for reuse while also treating the solid waste well.

[0100] 8. It is movable. The outer shell is installed on the sewage treatment and reuse device, and pulleys are installed at the bottom of the outer shell to achieve movement.
