Description

Technical Field

[0001] This utility model belongs to the field of water treatment equipment technology, and more specifically relates to a primary reverse osmosis greywater reuse device with activated carbon. Background Technology

[0002] Traditional greywater treatment equipment often has some shortcomings in the treatment process. For example, the filtration precision of some equipment is not high enough, resulting in the treated water quality failing to meet high water quality standards. It cannot effectively remove fine impurities, microorganisms, and some dissolved pollutants from the water, thus limiting the scope of reuse. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a primary reverse osmosis wastewater reuse device with activated carbon.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a primary reverse osmosis greywater reuse device with activated carbon, comprising a greywater reuse tank, several pre-filters, a first water tank, several parallel ultrafilters, a second water tank, a booster pump, a reverse osmosis membrane module, and a pure water tank. The several parallel ultrafilters are connected to the first water tank, and the filtered water enters the second water tank. The booster pump is located between the second water tank and the reverse osmosis membrane module. The pure water outlet of the first reverse osmosis membrane module is connected to the pure water tank, and the concentrated water outlet is discharged through a sewage pipe. The several pre-filters include a multi-media filter, an activated carbon filter, and a precision filter connected in sequence to filter the wastewater treated in the greywater reuse tank step by step. The wastewater outlets of the multi-media filter and the activated carbon filter are connected to the sewage pipe.

[0005] Furthermore, the reverse osmosis membrane module includes at least three reverse osmosis filters connected in parallel. The inlet of each reverse osmosis filter is connected to a booster pump, the pure water outlet of each reverse osmosis filter is connected to a pure water tank, and the concentrate outlet is connected to a sewage pipe.

[0006] Furthermore, the inlet of the multiple parallel ultrafiltration filters is connected to the first water tank, the purified water outlet is connected to the second water tank, and the wastewater outlet is connected to the sewage pipe.

[0007] Furthermore, a bypass pipe is provided between the inlet and outlet of the booster pump, and a bypass valve is provided on the bypass pipe.

[0008] Furthermore, it also includes a first delivery pump connecting the first water tank and the ultrafiltration unit, a second delivery pump connecting the pure water tank, and a raw water pump connecting the greywater reuse tank.

[0009] Furthermore, liquid level sensors are installed in the first water tank, the second water tank, and the pure water tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by reasonably configuring multiple pre-filters, it can effectively remove impurities such as suspended solids, colloids, organic matter, odors and pigments from the water, improve the purity of the water quality, and provide a good water quality foundation for subsequent ultrafiltration and reverse osmosis treatment. The design of multiple parallel ultrafiltration and reverse osmosis filters not only improves the processing capacity of the equipment, but also enhances the stability of the system. Even if one filter fails, the other filters can still work normally, ensuring the continuity of reclaimed water reuse. Attached Figure Description

[0016] A primary reverse osmosis (RO) wastewater reuse system with activated carbon includes a wastewater reuse tank 1, several pre-filters, a first water tank 2, multiple parallel ultrafiltration units 3, a second water tank 4, a booster pump 5, a reverse osmosis membrane module 6, and a pure water tank 7. The multiple parallel ultrafiltration units 3 are connected to the first water tank 2, and the filtered water enters the second water tank 4. The booster pump 5 is located between the second water tank 4 and the reverse osmosis membrane module 6. The pure water outlet of the reverse osmosis membrane module 6 is connected to the pure water tank 7, and the concentrated water outlet is discharged through a sewage pipe. The several pre-filters include a multi-media filter 8, an activated carbon filter 9, and a precision filter 10 connected in sequence, which filter the treated water in the wastewater reuse tank 1 stage by stage. The wastewater outlets of the multi-media filter 8 and the activated carbon filter 9 are connected to the sewage pipe. Figure 1 As shown, in this preferred embodiment, the reverse osmosis membrane module 6 includes at least three reverse osmosis filters connected in parallel. The inlet of each reverse osmosis filter is connected to a booster pump 5, the pure water outlet of each reverse osmosis filter is connected to a pure water tank 7, and the concentrate outlet is connected to a drain pipe. Figure 1 As shown, in this preferred embodiment, the inlet of the plurality of parallel ultrafiltration filters 3 is connected to the first water tank 2, the purified water outlet is connected to the second water tank 4, and the wastewater outlet is connected to the sewage pipe. Figure 1 As shown, in this preferred embodiment, a bypass pipe 11 is provided between the inlet and outlet of the booster pump 5, and a bypass valve 12 is provided on the bypass pipe 11. Specifically, when the pressure is too high, the bypass valve 12 can be opened to allow the high-pressure water at the outlet of the booster pump 5 to flow back and reduce the pressure. Figure 1 As shown, in this preferred embodiment, it further includes a first delivery pump 13 connecting the first water tank 2 and the ultrafiltration unit 3, a second delivery pump 14 connecting the pure water tank 7, and a raw water pump 15 connecting the greywater reuse tank 1.

Figure 1 As shown, the treated wastewater is collected in the reclaimed water tank 1. The treated water is then pumped by the raw water pump 15 to several pre-filters. After passing through a multi-media filter 8, an activated carbon filter 9, and a precision filter 10, the treated water is filtered to form primary filtered water, which is then collected in the first water tank 2. The first transfer pump 13 connected to the first water tank 2 pumps the primary filtered water to several parallel ultrafiltration filters 3 to produce secondary filtered water, which is then collected in the second water tank 4. The secondary filtered water in the second water tank 4 is pressurized by the booster pump 5 and then pumped into the reverse osmosis membrane module 6. After passing through several parallel reverse osmosis filters, pure water is produced and collected in the pure water tank 7. The concentrated water is discharged through the sewage pipe. The pure water in the pure water tank 7 can be pumped to the water-using equipment by the second transfer pump 14.
