Description
Technical field
This practicality belongs to the reuse of wastewater technical field in water technology, specifically, relates to a kind for the treatment of unit of reverse osmosis concentrated water.
Background technology
In recent years, reverse osmosis technology has been widely used in the sewage treatment process of the industries such as chemical industry, food, metallurgy, and reverse-osmosis treated can produce the dense water of about 30%, and salinity, the hardness of reverse osmosis concentrated water are higher, direct discharge by serious environment pollution, and causes the waste of water resources.Reverse osmosis membrane can not deviate from carbon dioxide simultaneously, one-level is caused to produce water slant acidity, because carbonic acid gas cannot be removed, if without certain process, after one-level product water enters secondary product water, by Formed acid group and bicarbonate radical plasma, cause secondary to produce water deteriorating water quality, the dense water of de-salted water workshop section reverse osmosis discharge per hour is about 20T/h, enter trench, pose a big pressure to environmental protection, in the face of shortage and the water quality deterioration of water resources, the recycling of reverse osmosis concentrated water is imperative.
Summary of the invention
The purpose of this utility model is to provide the reverse osmosis concentrated apparatus for recovering of a kind of de-salted water, is again recycled by the dense water of discharge, reduces energy consumption and running cost, realize the treatment effect of brine waste near zero release by distillation, evaporative crystallization.
The technical solution of the utility model is: the reverse osmosis concentrated apparatus for recovering of a kind of de-salted water, by dense water tank, quartz sand filter, active carbon filtering device, reverse osmosis unit, distillation device, crystal system connects to form successively, intermediate water tank is provided with between active carbon filtering device and reverse osmosis unit, strainer flushing pump is provided with between dense water tank and quartz sand filter, NaOH dosing tank is provided with between active carbon filtering device and intermediate water tank, topping-up pump is provided with between intermediate water tank and reverse osmosis unit 5, active carbon filtering device outlet connects reverse osmosis unit, the dense water out of reverse osmosis unit is connected with distillation device, reverse osmosis unit through water out, the condensation-water drain of distillation device and the water outlet of crystal system are connected to water tank, by the recovery of purifying waste water of each step, supply needs water device, realize the recycling of water, the outlet of distillation device condensed water is connected with crystal system import, the inorganic salt of crystallization can be transported outward or supply further processing and utilization.
Reverse osmosis unit through the condensation-water drain of water out, distillation device and the water outlet of crystal system, all valve is set, water tank ingress arranges primer pump.
Crystallization can carry out evaporative crystallization and freezing and crystallizing, and the water of evaporative crystallization gained water of condensation and precipitation solid is all recycled.
The dense water of de-salted water workshop section reverse osmosis discharge per hour is about 20T/h, out dense water power is led is 5500 μ s/cm in reverse osmosis, Cl ionic concn is 1000mg/L, after reverse osmosis ionic membrane filters, conductance can reach 450 μ s/cm, and Cl ion is down to 100mg/L, is 15T/h close to aquifer yield, the dense water that reverse osmosis is discharged is about 5T/h, again through distillation and crystallization, water reclaims further, creates benefit to enterprise.
The advantage that the utility model has and positively effect are: the utility model, first to reverse osmosis concentrated water temporary reservoir, is used for just washing and backwash quartz filter and activated charcoal filter, have carried out fully effective utilization to water resources.De-salted water reverse osmosis concentrated apparatus for recovering structure is simple, not containing other devices such as electrodialysis, without the need to softening and precipitation, with low cost, and final without concentrated water discharge, often walk all reusing through water of gained, the height achieving water utilizes, inorganic salt in water also can processing and utilizing further, on environment without impact.
