The system comprises a three-stage reaction tank or a reaction pot and at least a one-stage purifying sedimentation tank; a medicine storage device is arranged in each stage of the reaction tank or beside the reaction tank; a residue precipitating chamber is arranged at the bottom part of the tank; a high pressure water spraying device is arranged on each stage of the purifying sedimentation tank; the drainage outlet of each stage of purifying sedimentation tank is provided with a metal mesh; and a water valve used for adjusting the opening degree is arranged between the three-stage reaction tank and the purifying sedimentation tank. The utility model has the advantages of low construction cost, low operation cost, low processing cost, easy operating control and good waste water treatment effect, and is particularly suitable for being adopted by small and medium-sized enterprises which participate in market competition.
Description
Technical field
The utility model relates to a kind of Sewage treatment systems, the Treatment of acidic fluoride-containing waste water system after a kind of specifically graphite is purified.
Technical background
In graphite purify to be produced, can produce a large amount of fluorine-containing acid waste waters, need handle it and could discharge traditional method employing Ca (OH) after up to standard
2, CaCL
2Post precipitation adds AL
2(SO4)
3The acidic fluoride-containing waste water that produces in the coagulating treatment graphite purification process, processing cost is higher, and the sludge quantity that produces is big, be not easy operation, treatment effect is bad, therefore provides a kind of investment little, and running cost is low, easy to operate, it is particularly necessary that the Treatment of acidic fluoride-containing waste water system after the graphite that the medium-sized and small enterprises that are particularly suitable for participating in market competition adopt is purified just seems.
Summary of the invention
The purpose of this utility model is the deficiency that solves the problems of the technologies described above to provide a kind of investment little, and running cost is low, and is easy to operate, the Treatment of acidic fluoride-containing waste water system after the graphite that the medium-sized and small enterprises that are particularly suitable for participating in market competition adopt is purified.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: the Treatment of acidic fluoride-containing waste water system after a kind of graphite is purified, comprise the third order reaction pond and the purification settling tank of one-level at least, in the reaction tank of each grade or by the reaction tank, be provided with medicament reservoir, be provided with precipitation residue chamber at the bottom of the pond, on the purification settling tank of each grade, be equipped with high-pressure sprayer.
The utility model, described reaction tank also can replace with retort.
The utility model, described purification settling tank are six grades of purification settling tanks, are provided with wire cloth every grade of purification settling tank water port, impurity suspended substance in the filtering water.
The utility model, described medicament reservoir can be storage bag, storage tank or other similar containers, are used to store the used chemicals of purifying liquid waste.
The utility model is provided with the water valve of adjustable opening between described third order reaction pond and the set purification settling tank.
During the utility model work, waste water enters first step reaction tank from water-in, successively through being discharged by water outlet after second stage reaction tank, third stage reaction tank and six grades of purification settling tank purifying treatment.
The beneficial effects of the utility model are:
1, construction cost is low, and working cost is low, and processing cost is low.
2, easy handling control, wastewater treatment speed is fast, and flow is big, good purification.
3, being particularly suitable for the medium-sized and small enterprises of participating in market competition adopts.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark among the figure: 1, reaction tank, 2, reaction tank, 3, reaction tank, 4, purify settling tank, 5, medicament reservoir, 6, water-in, 7, precipitation residue chamber, 8, wire cloth, 9, water outlet, 10, high-pressure sprayer, 11, water valve.
Embodiment
As shown in Figure 1, waste water enters first step reaction tank 1 from water-in 6 earlier, pool volume is 16.5 cubic metres, the medicament reservoir 5 of suspending in midair in the pond is the storage bag of porous, a large amount of CaO are arranged in the storage bag, when treating that waste water face height reaches 1.3 meters (being that liquid level floods the suspension calcium oxide) in the pond, turn down water valve 11 between the reaction tank 1,2, make in the pond fluoride waste fully and Ca (OH) to 1/3 of original aperture
2Contact reacts.Reaction times continues after 30 minutes, open the water valve 11 between the reaction tank 1,2 fully, make a large amount of waste water after the reaction treatment enter second stage reaction tank 2, the water valve 11 at 2 two ends, off-response pond, open the medicament reservoir 5 that NaOH alkali lye is housed, make the waste water neutralization reaction, detect the control pH value 11～13 with the PH meter, be sprayed into flocculation agent this moment, and the complete remaining lead of unreacted, fluorine, copper etc. combine with flocculation agent and produce precipitation residue chamber 7 and the water sepn that throw out is settled down to the bottom, pond in flocculation agent and the water.Open the water valve 11 between the reaction tank 2,3, make waste water enter third stage reaction tank 3, open on the third stage reaction tank 3 AL is housed
2(SO
4)
3Medicament reservoir 5, the limit is put the soup limit and is stirred, hybrid reaction 30 minutes is adjusted to neutrality with the waste water pH value, being measured as 6～8 with the PH meter.Through its fluorine content of waste water behind the third-order reaction through chemical detection less than 10mg/L, the waste water that chemical index is qualified enters six grades and purifies settling bowl 4, the high-pressure sprayer 10 ejection water columns of pool side, graphite particle and other suspended substances on waste water surface are squeezed in the water, because of the proportion of graphite proportion greater than water, so after six grades of purification sedimentations, graphite particle in the water all sedimentation is gone at the bottom of the pond, make water finally reach so clear that you can see the bottom, other non-graphite particle suspended substance then removes by filter by the 500 purpose wire cloths 8 that reach that are provided with every grade of settling bowl water port, the last COD and the SS suspended substance of water after testing all can reach emission standard, are discharged by water outlet 9.
The utility model, reaction tank 1,2,3 and purification settling bowl 4 must be done inside lining anti-corrosive with resin or rubber plate and handle.
