Abstract
The invention discloses a treatment system for flue gas and reverse osmosis concentrated water. The treatment system comprises a collection device for collecting coal-fired flue gas, a reaction device for contact reaction of the flue gas with the reverse osmosis concentrated water, and a flocculation device and a filter device which are used for subsequently treating the water after the reaction. Compared with the prior art, a treatment method is simple and easy to implement, the investment expense of treatment facilities is low, the treatment cost is low, the system is environment-friendly, the discharge of the reverse osmosis concentrated water is reduced, the atmospheric pollution caused by direct discharge of the flue gas is prevented, and the waste gas treatment is organically combined with the reverse osmosis concentrated water treatment.
Description
Technical field
The present invention 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, SO
2, N
2, O
2, CO, CO
2hydrocarbon polymer and oxynitrides etc., 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 object of this invention 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 present invention 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 object of this invention is to provide a kind of efficiently, the treatment system of the dense water of RO cheaply.
The object of the present invention is achieved like this: a kind for the treatment of system of reverse osmosis concentrated water, 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 invention has the beneficial effects as follows, solve reverse osmosis concentrated water discharge because the high problem that causes environmental pollution of salinity has improved the rate of recovery of reverse osmosis membrane to water greatly, by general 50%～75%, brought up to 90%～100%, utilize discarded coal-fired flue-gas simultaneously, 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.
