Abstract
The present invention relates to a kind of hydrogen in statu nascendi iron oxide precipitation that utilizes and filter the water treatment method removing vitriol, it is characterized in that: hydrogen in statu nascendi iron oxide precipitation is mixed with fine sand, makes filtrate for subsequent use; Utilize the water body of aforesaid media filtration containing sulfate.
Description
Technical field
The present invention relates to water treatment method, especially a kind of hydrogen in statu nascendi iron oxide precipitation that utilizes filters the water treatment method removing vitriol.
Background technology
At present, all there is the phenomenon that vitriol exceeds standard in underground water, drinking water source, has a strong impact on drinking-water quality, is detrimental to health.In water vitriol exceed standard can cause water acidification, have peculiar smell, the growth of harm hydrobiont; Long-term drinking there will be the diseases such as diarrhoea, maldigestion, intestinal function disorder; Agriculturally, use containing the high-concentration sulfuric acid body of salt meeting of irrigation spoiled soil structure, form saltings, suppress crop growth, reduce crop yield.In the industrial production, use and can cause hydrophone fouling, corrosion pipeline and equipment containing high-concentration sulfuric acid body of salt, form higher potential safety hazard.
In existing removal water body, the method for vitriol comprises lime method, barium chloride method, ion exchange method, absorption method, embrane method etc.Lime method less investment, technique is simple, can remove water Fe simultaneously
2+, Cu
2+deng metal ion, but long reaction time, water outlet pH value is high, and sludge creation amount is large, and easily cause secondary pollution, the application of the method in engineering reduces just gradually.The advantages such as barium chloride method removal efficiency is high, technique is skillful, flow process is short, but cost is high, easily causes heavy metal contamination.The advantages such as ion exchange method has fast, efficient, selectivity is strong, but pre-processing requirements is strict, and facility investment is high.The absorption starting material that absorption method adopts have pyrrhosiderite stone, hydrotalcite, pillared montmorillonite, although cost is lower, filter effect is unsatisfactory.Membrane separating efficiency is high, environmental friendliness, and energy consumption is low, easy to operate, but cost is high, is difficult to realize extensive operation.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of hydrogen in statu nascendi iron oxide precipitation that utilizes to filter the water treatment method removing vitriol, with low cost, good filtration effect.
Realize the technical scheme of the object of the invention:
Utilize hydrogen in statu nascendi iron oxide precipitation to filter the water treatment method removing vitriol, it is characterized in that: ferric hydroxide precipitate is mixed with fine sand, make filtrate for subsequent use; Utilize the water body of aforesaid media filtration containing sulfate.
Ferric hydroxide precipitate forms by being mixed with ferric iron solution and sodium hydroxide solution.
When filtrate absorption is saturated, back flushing is carried out to filtrate.
The ratio of weight and number of ferric hydroxide precipitate and fine sand is 1: 5 ~ 1: 6.
During preparation ferric hydroxide precipitate, the mole number of ferric ion and mole ratio hydroxy are 1:2.5.
When utilizing filtrate to carry out adsorption filtration, filtrate is placed in the surface of filter bed, filtering velocity remains on 6-10m/h.
Ferric salt solution is selected from one or more the mixing salt in iron trichloride, iron nitrate, poly-ferric chloride, polymerization iron nitrate.
The beneficial effect that the present invention has:
Hydrogen in statu nascendi iron oxide precipitation mixes as filtrate with fine sand by the present invention.Due in aqueous, ironic hydroxide not only can adsorbing metal ions, and can fix negatively charged ion, and have extremely strong adsorptive power, the present invention effectively can carry out adsorption filtration to the vitriol in water body.The present invention, when filtrate absorption is saturated, carries out back flushing to filtrate, can realize the recycle of filtrate.
The raw material sources that the present invention adopts are extensive, with low cost, are easy to obtain.Realize water treatment method of the present invention, can transform on the basis of existing technology and equipment, fixed investment is few, simple.The present invention effectively can not only remove vitriol, and can process the metal ions such as copper, lead, arsenic, cadmium simultaneously.Running cost is low, and treatment scheme is simple, and processing efficiency is high, and Matter Transfer utilizes, pollution-free, less investment.
Embodiment
First be dissolved as ferric salt solution with one or more in iron trichloride, iron nitrate, poly-ferric chloride, polymerization iron nitrate, by ferric salt solution and sodium hydroxide solution hybrid reaction, the mole number of ferric ion and mole ratio hydroxy are 1: 2.5.After complete reaction, natural filtration, obtains the ferric hydroxide precipitate of nascent state, for subsequent use.
By the cleaning of common fine sand, drying, for subsequent use.
Above-mentioned newly-generated ferric hydroxide precipitate is mixed with fine sand, makes homogeneous filtering material.The ratio of weight and number of ferric hydroxide precipitate and fine sand is 1:5 ~ 1: 6,
Make filter bed, make supporting layer with small-sized goose soft rock, haydite is middle layer, and above-mentioned newly formed homogeneous filtering material is laid on surface.
Containing sulfate water body enters from filter bed top, bottom water outlet, and natural filtration, filtering velocity remains on 6-10m/h.
When filtrate absorption is saturated, carry out back flushing, recover the Adsorption Filtration Properties of filtrate.
Beneficial effect of the present invention is further illustrated below in conjunction with water treatment experiment.
Experiment one:
Utilize water treatment method process water factory of the present invention surface water, before process, in water, sulphate content is 500mg/L, and treatment effect is as shown in table 1.
Table 1 processes certain water factory's surface water
From the results shown in Table 1, after process, in water, sulphate content significantly reduces.
Experiment two:
Utilize process somewhere of the present invention underground water, before process, in water, sulphate content is 600mg/L, and treatment effect is as shown in table 2.
Table 2 processes certain underground water
From the results shown in Table 2, after process, in water, sulphate content obviously reduces.
