Background technology

For the Freshwater resources situation extremely in short supply that the present whole nation and even the whole world faced, we should do one's utmost the development resource reuse technology.At present, the technology of domestic relevant water resources recycling aspect still rests on the primary stage, basically just use such as floor are flushed the toilet, water flowers, are cleaned in the reuse conduct, the water quality of recycle-water has also just just reached the water quality standard of reclaimed water, does not reach the water quality standard of industrial electro sub level pure water at all.

Now, the desalting system that ultrapure water is produced in the dirty wastewater zero discharge reuse of domestic industry all adopts traditional multiple bed ion-exchange+reverse osmosis+mixed bed ion exchange process to finish, not only floor space is big, also exists according to cycling, causes secondary pollution, cost height, disadvantages such as the operational hazards factor is many, labour intensity is big, water quality instability.

The dirt of wiring board industry, waste water circulation system production line are support equipments indispensable in the new high-tech product production processes such as electronics and IT products, optoelectronic information product, wiring board; it is the high-end product of reusing of energy source and environment protection; be the infrastructure device that high-tech product is produced, can be rated as the foundation stone of high-tech product.Other high-tech products such as the radio components assembly that the high purity water that it provided is produced for the high purity water technology, optical component package, high-grade material have immeasurable significance to China's national economy.The dirt of wiring board industry, waste water circulation system production line are effective assurances that the recycle water resources is produced electron-grade water, the dirty waste water recycling technology of China has been brought up to a higher level again, and it will play crucial effects to promoting China's development of high-tech.Simultaneously, further improving of this achievement also will be the model in energy-conservation joint source, and it has not only protected our the deficient day by day water resources of country effectively, and significant to strengthening Chinese national economy competitive strength in the international market.

The utility model content

At above-mentioned technical problem, the utility model provides a kind of technology simple, operational safety, and can effectively realize the industrial wastewater pollution zero release electronic-grade reuse integrating device that quality of reused water is stable.

The technical scheme that the utility model is taked is, a kind of industrial wastewater pollution zero release electronic-grade reuse integrating device, comprise by regulating tank, high-pressure pump, the multi-medium filtering device, active carbon filtering device, the pretreatment system A that chemicals dosing plant is linked in sequence and constitutes, it is characterized in that: also comprise the ultrafiltration system B that forms by ultra-filtration equipment, by intermediate water tank, high-pressure pump, the reverse osmosis system C that reverse osmosis unit is linked in sequence and forms, and by the TOC device, mixing tank, the reverse osmosis water tank, high-pressure pump, the electric deionization D of system that the EDI device sequence connects to form, ultrafiltration system B and pretreatment system A connect reverse osmosis system C and the electric deionization D of system thereafter successively by pipe connection; The former water of industry is discharged reuse through after the above-mentioned four systems effect through the EDI device, simultaneously, and the H that produces in the EDI device ⁺With OH ^-Be conveyed into intermediate water tank by exchange membrane.

Described industrial wastewater pollution zero release electronic-grade reuse integrating device, wherein, the device that the TOC device also can adopt ultraviolet sterilizer etc. to have disinfection function is replaced.

The utility model concentrates reverse osmosis unit with multistage and combines with EDI device two big state-of-the-art technologies, can filter the former water of industry, purify, a series of automatic treatment process such as electric deionization, make it reach the reuse of electronic-grade ultrapure water, not only greatly reduce the intensity and the danger of processing cost and work, and can effectively ensure the stability of water quality, avoid causing secondary pollution.

Embodiment

As shown in drawings, the utility model comprises pretreatment system A, ultrafiltration system B, reverse osmosis system C and four parts of the electric deionization D of system.Be stored in the dirty waste water of industrial enterprise in the regulating tank 1 under the high-pressure pump effect, pass through the effect of multi-medium filtering device 2, active carbon filtering device 3 successively, chemicals dosing plant 4 is to add the sterilization and disinfection material in the former water simultaneously, behind a series of biochemistry, precipitation pretreatment process, deliver in the ultrafiltration system B that forms by ultra-filtration equipment 5 by topping-up pump.Ultra-filtration equipment 5 can be handled and can make the higher SDI value that reverse osmosis membrane stops up and the water of turbidity.The general particle of removing little as 0.01 μ m of ultra-filtration equipment, thus high-quality reverse osmosis feed water produced.

Be better than conventional method for pretreating with ultrafiltration or the pretreated water quality of microfiltration membrane, and can remove intestinal bacteria and bacterium.Pre-treatment mostly is the tubular fibre structure with micro-filtration (membrane pore size is 0.2 μ m) and hyperfiltration membrane assembly, and mould material is polypropylene, sulfonated polyether sulfone etc., adopts the backwash of pulse of compressed air formula, can work under very low cross-flow velocity, even can work under no flow state.Compare with conventional pre-treatment, have design to be easy to stdn, operation is easy to automatization, need not to drop into continuously chemical reagent, saves advantages such as energy consumption and manpower.The pre-treatment of ultrafiltration should design according to the contained pollutent of charging equally, uses the strainer of an aperture 5 ~ 10 μ m to remove wherein suspended substance, iron rust usually, also can flocculate earlier in case of necessity, pre-filtering again.

Reverse osmosis system comprises intermediate water tank 6, high-pressure pump and reverse osmosis unit 7.Reverse osmosis unit utilizes reverse-osmosis membrane element to remove the mineral ion and the organism of major part (about 95%), because reverse osmosis is the physical method desalination, provides the energy of desalination by high-pressure pump, and not resembling needs frequent regeneration the ion-exchange, can obviously reduce working cost.

Water after handling through reverse osmosis system C with after the virus killing material exported in the TOC device 8 mixes, enters in the reverse osmosis water tank 10 mixing tank 9 in.Water in the reverse osmosis water tank 10 offers EDI device 11 by the EDI water pump, produces the required work water pressure of ion-exchange.EDI device 11 utilizes well-mixed ultrapure water level Zeo-karb and ultrapure water level anionite-exchange resin that the cationic exchange of minute quantity in the water is become H ⁺, the anionresin of minute quantity becomes OH ^-, and and H ⁺Synthesize H ₂O guarantees that water outlet satisfies service requirements (resistivity＞16M Ω CM) fully.Pure water is under electric field action, and ionization goes out H ⁺And OH ^-Resin is regenerated, and the positively charged ion that displaces enters dense hydroecium by cationic exchange membrane, and the negatively charged ion that displaces enters dense hydroecium by anion-exchange membrane.Therefore, EDI does not need to regenerate with acid, alkali again, stable effluent quality, and avoided pollution to environment.
