Problems solved by technology

[0012] Conventional membrane methods for water treatment have extremely high requirements on influent water quality, and require huge investment, low recovery rate, and the concentrated solution produced is more difficult to treat. The incomplete treatment of pollutants in the front-end biochemical system will lead to the failure of membrane modules required for advanced treatment. Pollution, affecting the treatment effect
[0013] To sum up, using traditional physicochemical + biochemical technologies to treat industrial wastewater, especially high-concentration, high-salt, and highly refractory wastewater, not only requires huge investment and high treatment costs, but also has very limited treatment effects.

Embodiment 1

[0047] Such as figure 1 As shown, the new treatment technology for high-concentration industrial wastewater includes pretreatment unit, SUPER membrane element functional membrane unit and evaporation unit.

[0048] The pretreatment unit includes a wastewater regulating tank, a water pump and a filtration system, the filtration system is an ultrafiltration filtration system or a microfiltration filtration system or a sand filtration system, and the industrial wastewater is removed from colloids and suspended particles after passing through the pretreatment unit It becomes pre-treated wastewater, and then the pre-treated wastewater enters the SUPER membrane element functional membrane unit for the second step of treatment.

[0049] The functional membrane unit of the SUPER membrane element includes a water pump and a reverse osmosis membrane device. Under the action of the water pump, the pretreated wastewater is pumped into the reverse osmosis membrane device for reverse osmosi...

Embodiment 2

[0055] Such as figure 2 , 3 , 9, the sewage diversion filter device includes at least two diversion plates 1 and a diaphragm 10 used in conjunction with each other, wherein the diversion disc 1 and the diaphragm 10 are adjacent to each other, and the number of diversion discs 1 One more than the number of diaphragms 10, the guide plate 1 is a disc with a center hole 7 in the guide plate, and a boss is also arranged on the surface of the guide plate 1. On the guide plate 1 There are also two diversion slits 3 , and two orientation slits 13 matching the diversion slits 3 are arranged on the diaphragm 10 . There is a ring of protruding teeth 8 arranged along the radial direction on the outer side of the hole 7 of the above-mentioned deflector plate. The protruding teeth 8 are fixed on the inner edge of the deflector plate 1, and gaps are provided between the protruding teeth 8. The gaps are diversion gaps. , the setting positions of the upper and lower sides of the protruding ...

Embodiment 3

[0060] Such as Figure 4 , 5 As shown, the difference between this embodiment and Embodiment 1 lies in that the bosses are convex strips 9 , and the convex strips 9 are arranged on both sides of the deflector plate 1 in a certain arc in sequence. The convex line 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 contact area between the convex line and the diaphragm Larger, which further reduces the force on the surface of the diaphragm, better avoids the damage of the diaphragm during use, improves the service life of the diaphragm, reduces the maintenance frequency during use, and greatly improves the use effect.

Abstract

The invention discloses a novel treatment technology of high-concentration industrial wastewater. A pretreatment unit, a membrane unit with a SUPER membrane element function and an evaporation unit are used in the novel treatment technology. The invention discloses a reverse osmosis membrane device which comprises a round pipe bearing outer shell, a metal seal sheet, a flange plate, a fluid reversing plate, a seal type round pipe bearing inner shell, a water distributor, an inner pull rod, a supporting flow guide plate, a membrane, a liquid inlet pipe and a liquid outlet pipe. According to the novel treatment technology of high-concentration industrial wastewater, a system is high in reliability and integrity, high in automation level, small in occupied area and relatively high in pollutant removal rate, and economic benefits of enterprises are well increased.

Description

technical field [0001] The invention relates to a wastewater treatment technology, in particular to a novel treatment technology for high-concentration industrial wastewater. Background technique [0002] At present, in the field of industrial wastewater treatment, especially for high-concentration, high-salt, and highly refractory wastewater, there is no more effective and general-purpose technology and method to treat it, because of the particularity of water quality and the limitations of traditional physicochemical and biochemical methods. sex. [0003] Water Quality Characteristics of Industrial Wastewater [0004] Industrial wastewater, especially wastewater with high concentration, high salt content, and high refractory degradation, has complex water components and high organic content. COD (chemical oxygen demand) is generally above 10,000 mg / L, or even as high as tens of thousands to hundreds of thousands of mg per liter. , containing toxic and harmful substances,...
