Description

Nanofiltration strengthens concentrated strong brine device in conjunction with chelate separation process
Technical field
The utility model relates to high density, high rigidity strong brine thickening equipment technical field, and specifically nanofiltration strengthens concentrated strong brine device in conjunction with chelate separation process.
Background technology
At water treatment field, in the technological process that strong brine is concentrated, there is the divalent cation that concentration is more and more higher in strong brine, very easily form scale forming matter with the negatively charged ion such as sulfate radical and carbonate and make to become very difficult further by membrane concentration.The energy consumption that hot method concentrates is too high, and processing cost is high, and enterprise profit is few.
Recent years, along with reverse osmosis technology is applied to industrial water supply and reusing sewage, wastewater treatment, create a large amount of high density salt solution, sometimes high density salt solution not easily directly discharges, and adopts the method for evaporation to consume a large amount of energy again, in a lot of occasion, the demand of approximate zero draining technology is urgent and real, discharged by approximate zero and improve brine concentration further, reduce the treatment capacity of next step evaporation, thus save a large amount of energy consumptions.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provide a kind of rational in infrastructure, production cost is low, the nanofiltration of environmentally safe strengthens concentrated strong brine device in conjunction with chelate separation process.
The utility model solves the technical scheme that its technical problem adopts: this nanofiltration strengthens concentrated strong brine device in conjunction with chelate separation process and comprises cartridge filter, high-pressure pump and electrodialysis unit, cartridge filter entrance and pending strong brine pipeline communication, pending strong brine pipeline is communicated with respectively and adds NaOH device and add DTPA device; The outlet of cartridge filter is communicated with high-pressure pump by pipeline, high pressure pump outlet is communicated with nanofiltration separation device portal by pipeline, the outlet of nanofiltration separation device is communicated with electrodialysis unit by DTPA complex state hyperconcentration brine pipeline, and the outlet of electrodialysis unit removes the hyperconcentration brine pipeline of DTPA.
Described DTPA complex state hyperconcentration brine pipeline is communicated with means for feeding acid.
Described electrodialysis unit is communicated with cartridge filter by DTPA solution line.
Compared to the prior art nanofiltration of the present utility model strengthens concentrated strong brine device in conjunction with chelate separation process, have reasonable in design, be easy to processing, energy consumption is low, concentration rate is high more, this device can process divalent ion, the hardness ions of greater concn, most of DTPA in energy recovered brine, discharge of wastewater is avoided less to environment.
