Detailed ways

As shown in Figure 1, the domestic sewage regeneration treatment and recycling device described in the utility model is provided with a plurality of partitions 11 with water holes in a box body 1, so that the box body 1 is divided into several chambers. The chambers from upstream to downstream are biological filter chamber 2, hydrolysis acidification chamber 3, biological contact oxidation chamber 4, coagulation reaction chamber 5, high-efficiency sedimentation chamber 6, biological carbon adsorption filter chamber 7 and clean water chamber 8. in:

The biofilter chamber 2 is provided with a water inlet pipe deflector 21 which extends to the bottom of the biofilter chamber 2, and a biofilter bed 22 is fixed in the middle of the chamber. In addition, a first water hole 23 is opened on the downstream partition 11 to communicate with the hydrolysis acidification chamber 3 and is located above the biological filter bed 22 .

A hydrolytic acidification filling material 31 is fixed in the middle of the hydrolysis acidification chamber 3, an underwater jet mixer 32 is provided at the bottom of the chamber, and a second water hole 33 is opened below the downstream partition 11 to contact the biological oxidation chamber 4. connected.

The middle part of the biological contact oxidation chamber 4 is fixed with a biological contact oxidation filling material 41, an underwater aerator 42 is provided at the bottom of the chamber, and a third water hole 43 is provided above the downstream partition 11 to communicate with the mixing chamber. The coagulation reaction chamber 5 communicates.

A coagulant dosing device 51 is provided above the coagulation reaction chamber 5 , and a fourth water hole 52 is opened in the middle and lower part of the downstream partition 11 to communicate with the high-efficiency sedimentation chamber 6 .

High-efficiency sedimentation filler 61 is fixed on the middle and upper part of the described high-efficiency sedimentation chamber 6, and a drainpipe 62 with a valve is installed on the panel of the horizontal plane above the filler, and a funnel-shaped mud-water separator 63 and a collector are installed at the bottom of the chamber. The mud chamber 64 also has a fifth water hole 65 above the downstream partition 11 to communicate with the biochar adsorption filter chamber 7 .

In the middle of the biochar adsorption filter chamber 7, a biochar filter material 71 is fixed, and a water flow deflector 72 is fixed below the downstream partition 11, and the water flow deflector 72 extends upward and connects with the clean water chamber 8. connected.

A UV-C disinfection device 81 is installed in the clean water chamber 8 , and a reclaimed water pump 82 and a recycled water reclaimed water pipe 83 are installed at the bottom thereof, and a tap water compensator 84 is also installed at the same time.

In addition, a sludge discharge pipe 12 with a valve is installed on the outside of the bottom plate of the box body 1 to communicate with the bottom of each chamber, so that the sludge in each chamber can be discharged conveniently.

When the utility model is in use, the sewage first enters the biological filter chamber 2 through the water inlet pipe-type deflector 21, and since the deflector 21 extends to the bottom of the chamber, the sewage directly enters the biological filter chamber 2 The bottom rather than the top, so that when the sewage is filtered through the biological filter chamber 2, it will infiltrate into the biological filter bed 22 from the bottom to filter, instead of filtering from the top to the bottom as in the traditional technology. Since there is a lot of silt in the sewage, if it is filtered from the top down, the silt will easily fall on the top of the biological filter bed and block the filter material. If it infiltrates upwards from the bottom, the sludge will naturally sink to the bottom of the chamber without clogging the filter material. The valve can be opened to discharge from the mud discharge pipe 12 afterwards.

After the sewage filtered through the rough part of the biological filter chamber 2 enters the hydrolysis and acidification chamber 3 through the first water hole 23, the hydrolysis and acidification filling material 31 in it carries out the hydrolysis and acidification reaction, and the underwater jet mixer 32 at the bottom Then the hydrolyzed and acidified filling material 31 can be fully mixed with the sewage to make the reaction more complete. Afterwards, the sewage enters the biological contact oxidation chamber 4 through the second water passage 33 for oxidation treatment, and the underwater aerator 42 in it is equivalent to the above-mentioned underwater jet mixer 32, which can make the oxidation more sufficient.

The oxidized water enters the coagulation reaction chamber 5 through the third water passage hole 43 above, and mixes with the coagulant at the same time, so that the fine dirt in the sewage is combined to form larger particles of dirt, and then The lower fourth water hole 52 enters into the high-efficiency sedimentation chamber 6 .

Since the fourth water hole 52 is set in the middle and lower part, and there is a funnel-shaped mud-water separator 63 under it, the water naturally forms a spiral shape, so that heavier dirt enters the sludge from the outlet at the bottom chamber 64, and because the outlet is small, once the dirt enters the mud collection chamber 64, it is not easy to float out, and the water is filtered again through the high-efficiency sedimentation filler 61 above. Since then, the sewage has been treated at the first level and can reach the discharge standard. If it does not recycle, it can be discharged by the drain pipe 62 above.

If you want to further process the water to achieve the purpose of recycling, the water will continue to enter the biochar adsorption filter chamber 7 through the fifth water hole 65, filter the biochar filter material 71, and then pass through the water guide 72 and enter the clean water chamber 8, because the water flow deflector 72 extends upwards, so it can play the role of sedimentation dirt again. The water that reaches the clean water chamber 8 is then subjected to ultraviolet photochemical radiation reaction by the ultraviolet C disinfection and sterilization device 81, which can effectively kill bacteria and viruses, make the purified water safer and more reliable, and cause no secondary pollution to humans, animals and the ecological environment. Finally, the purified clear water is discharged by the return water pump 82 and the reclaimed water return pipe 83, and can be used for toilet flushing, road cleaning, fire protection, urban greening, vehicle washing, non-drinking water for building construction and water for landscape environment.
