Description
Technical field
The utility model relates to the processing of flue gas and the treatment facility of reverse osmosis concentrated water, more particularly utilize the flue gas of discharge and the reverse osmosis concentrated water of discharge to react to each other after up to standard or treatment systems of being purified all, belong to environmental technology field.
Background technology
Reverse osmosis process is as the widespread use in all trades and professions of a kind of efficient, clean desalting technology, but have in process of production the concentrated water discharge that accounts for greatly total inflow 25%～30%, this point has caused the significant wastage of water resources today increasingly in short supply in water resources, and serious overslaugh the further popularization of reverse osmosis technology.
The feature of the dense water of reverse osmosis system discharge is: saltiness is high, PH is high, basicity is large, has bacterium and organism to exist.
Flue gas is the mixture of gas and flue dust, is the major cause of polluting Residential areas atmosphere.The composition of flue gas is very complicated, and gas comprises water vapor, SO2, N2, O2, CO, CO2 hydrocarbon polymer and oxynitrides etc., and flue dust comprises ash content, coal grain, oil droplet and the high-temperature split product etc. of fuel.Therefore flue gas is the combined pollution of multiple poisonous substance to the pollution of environment.Flue dust is relevant with the size of particle to the hazardness of human body, human body is produced to the floating dust that diameter is less than 10 microns that is mostly of harm, especially maximum with the floating dust hazardness of 1-2.5 micron.
The purpose of this utility model is to provide a kind of simple, cheap treatment system of utilizing flue gas and these two kinds of waste resources of reverse osmosis concentrated water, Main Function is the saltiness that reduces reverse osmosis concentrated water on the one hand, regulate pH value, remove organism, the water inlet requirement that reverse osmosis concentrated water is reached again enter reverse osmosis membrane, the rate of recovery that improves reverse osmosis membrane, prevents reverse osmosis membrane fouling; That the flue gas of discharge is effectively processed on the other hand, air conservation.
The utility model utilizes the ubiquitous coal-fired flue-gas of general industry enterprise to process reverse osmosis concentrated water, the effects such as precipitation desalination, neutralization, adsorption-flocculation have been played, both improved the rate of recovery of reverse osmosis membrane to water, take full advantage of again the coal-fired flue-gas of discharge, energy-conservation, water saving, emission reduction effect are remarkable.
Summary of the invention
In order to solve the not treated direct discharge of the dense water of current RO to problems such as environment, waste water resources, the purpose of this utility model be to provide a kind of efficiently, the treatment system of the dense water of RO cheaply.
The purpose of this utility model is achieved in that a kind for the treatment of system of reverse osmosis concentrated water, and this system comprises: coal-fired flue-gas collection device, flue gas and reverse osmosis concentrated water contact reacts device, flocculation deposition apparatus, filtration unit.Reverse osmosis concentrated water can be again after this system is processed as the water inlet of reverse osmosis membrane, if directly discharge also not can be because saltiness be high contaminate environment.
The beneficial effects of the utility model are, have solved reverse osmosis concentrated water discharge because the high problem that causes environmental pollution of salinity is utilized discarded coal-fired flue-gas simultaneously, have reduced topsoil.Coal-fired flue-gas and reverse osmosis concentrated water contact reacts, mainly played following effect:
Desalting--in fire coal boiler fume, contain a large amount of SO
2, CO
2deng composition, Ca, Mg plasma reaction that in they and reverse osmosis concentrated water, content is higher have generated CaCO
3, MgSO
4etc. precipitation, thereby reduced the saltiness of reverse osmosis concentrated water.
Neutralizing effect--in fire coal boiler fume, contain a large amount of SO
2, CO
2, H
2s, NO
xdeng sour gas, when fire coal boiler fume is when alkaline reverse osmosis concentrated water fully contacts, dense water reacts with flue gas generation acid-base neutralisation, and in dense water, excessive basicity is neutralized.
Adsorption and flocculation are used--in coal-fired flue-gas, be entrained with a large amount of small flue dust and unburnt small carbon granules (flyash), flue dust is similar to absorption Jiao and the active coal of external report in forming process, all under decompression and hot conditions, form, there is certain pore texture, active surface and adsorptivity.Inorganic dust in flue dust has clay characteristic, so coal-fired flue-gas played adsorption to the organism in water under contacting with reverse osmosis concentrated water, and in flue gas, inorganic dust has promoted organic flocculating settling in water.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model reverse osmosis thick water treatment system.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
A kind of flue gas and the reverse osmosis thick water treatment system of the present embodiment, contain: the smoke gas collecting apparatus 1 of collecting flue gas 6, to 8 reverse osmosis units of processing 5 of intaking, the reaction unit 2 that flue gas and reverse osmosis concentrated water 10 react, reacted dense water carries out flocculation deposition apparatus 3 and the filtration unit 4 of subsequent disposal, described smoke gas collecting apparatus 1 entrance is connected with flue gas 6, smoke gas collecting apparatus 1 outlet is connected with the inlet mouth of reaction unit 2, water inlet 8 is connected with the water-in of reverse osmosis unit 5, water purification goes out from the pure water inlet of reverse osmosis unit 5, the dense water out of reverse osmosis unit 5 is connected with the water-in of reaction unit 2, venting port qualified discharge through reacted flue gas 7 from reaction unit, the water outlet of reaction unit 2 is connected with the water-in of flocculation plant 3, the water outlet of flocculation plant 3 is connected with the water-in of filtration unit 4, the water outlet of filtration unit 4 is connected with the water-in of reverse osmosis unit 5, it is characterized in that: through reacted flue gas 7 qualified discharges, through reacted reverse osmosis concentrated water 11, turn back to again the feed-water end 8 of reverse osmosis unit, water purification 9 producing water ratios of reverse osmosis unit 5 improve.
