Embodiment 1

[0040] Such as figure 1 As shown, the zero-discharge technology for reclaimed water reuse is equipped with a biochemical effluent tank for holding biochemical effluent, and UF ultrafiltration devices, roll-type RO membrane devices, SUPER RO membrane devices, and evaporation devices are also arranged in sequence on the biochemical effluent tanks. , A clear water pool is also provided to connect with the roll-type RO membrane device, SUPER RO membrane device and evaporation device.

[0041] The biochemical effluent is exported from the biochemical effluent pool. After the macromolecular pollutants are filtered by the UF ultrafiltration device, the produced water cycle enters the biochemical effluent pool again, and the ultrafiltration concentrated water obtained after filtration enters the roll-type RO membrane device for the next step of concentration. .

[0042] The ultrafiltration concentrated water is divided into two parts after being concentrated by the roll-type RO membr...

Embodiment 2

[0048] Such as figure 2 , 3 As shown in , 9, a SUPER RO membrane device includes a circular tube pressure-bearing shell 1, metal sealing sheets 9 and flanges are respectively arranged at the upper and lower ends of the circular tube pressure-bearing shell 1, and the pressure-bearing The upper and lower ends of the shell 1 are respectively provided with a fluid reverse disc 2 adjacent to the metal sealing sheet 9 and the flange, and a sealed circular disc is also provided between the circular tube pressure-bearing shell 1 and the two fluid reverse discs 2. Tube pressure-bearing inner shell 5, inside the sealed round tube pressure-bearing inner shell 5, there are also supporting deflectors 3 and diaphragms 4, and a water distributor is also set at the lower end of the sealed round tube pressure-bearing inner shell 5 8. In the central position of the water distributor 8, there is also an inner tie rod that runs through and supports the deflector plate 3, the diaphragm 4, the up...

Embodiment 3

[0054] Such as Figure 4 , 5As shown, the difference between this embodiment and Embodiment 1 lies in that the bosses are convex strips 39 , and the convex strips 39 are arranged on both sides of the deflector plate 3 in a certain arc in sequence. The convex line 39 can better guide the dirty liquid, further reduce the pressure loss of the dirty liquid in the flow process, make better use of production resources, and reduce production loss; at the same time, the convex line 39 and the diaphragm 4 The contact area is larger, which further reduces the force on the surface of the diaphragm 4, better avoids the damage of the diaphragm 4 during use, improves the service life of the diaphragm 4, and reduces the maintenance frequency during use. Greatly improved the use effect.

Abstract

The invention discloses a zero-discharging technology in reclaimed water reuse. A biochemical water-discharging tank which is used for accommodating biochemically discharged water is arranged. An ultrafiltration device, a roll-type reverse osmosis membrane device, a super reverse osmosis membrane device and an evaporation device are successively arranged on the biochemical water-discharging tank. A clean water tank is connected to the roll-type reverse osmosis membrane device, the super reverse osmosis membrane device and the evaporation device. The invention discloses a super reverse osmosis membrane device which includes a circular tube pressure bearing outer shell, a metal sealing piece, a flange disk, a fluid reversing disk, a sealed circular tube pressure bearing inner shell, a water distributer, an inner pulling rod, a supporting and guiding disk, a membrane piece, a liquid inlet pipe and a liquid outlet pipe. The invention provides the zero-discharging technology in reclaimed water reuse, which can reduce energy consumption of sewage treatment and further reduce investment required in the sewage treatment. By means of the technology, a sewage treatment effect is improved and a zero-discharging requirement is achieved.

Description

technical field [0001] The invention relates to a SUPER RO membrane device and a zero-discharge method for reclaimed water reuse using the device. Background technique [0002] At present, many industries and regions all need to meet the "zero discharge" requirement of wastewater for some industrial enterprises. The so-called "zero discharge" means that the factory needs to realize the recycling and reuse of production raw materials and water resources, and requires no discharge of any waste liquid. [0003] For "zero discharge", most industrial enterprises are doing the following considerations according to their own industry and product characteristics: recycling useful production raw materials to reduce costs, reduce the load of sewage stations, and try their best to achieve completely clean production; reuse reclaimed water to reduce Sewage discharge; upgrading and reconstruction of sewage stations for advanced treatment and reuse. [0004] For the reuse of reclaimed w...
