The yielded clean water can be reused, a two-stage reverse osmosis unit conducts secondary concentration and filtration to concentrated water which is discharged from the first reverse osmosis unit, and the device has the advantages of reducing concentrated water quantity and increasing reused water quantity.

Description

The advanced treatment apparatus of dyeing waste water
Technical field
The utility model belongs to technical field of waste water processing, particularly a kind of advanced treatment apparatus of dyeing waste water.
Background technology
Dyeing waste water has characteristics such as the water yield is big, organic pollutant content height, alkalescence is big, change of water quality is big, belongs to one of unmanageable trade effluent.Because the use of various slurries and New-type adjuvant, the organic content of bio-refractory is bigger in the waste water, particularly passes through the tail water after materialization, the biochemical treatment, and concentration of suspension is low, and is mainly the bio-refractory material in the waste water.Current research mainly concentrates on the biodegradability research that how to improve dyeing waste water.On April 23rd, 2008, disclosed application number was that 200710069558.5 innovation and creation disclose a kind of integrated printing and dyeing waste water treatment process, this technology increases water quality conditioning technology in pre-treatment, adopt efficient water quality amendment, by with organism generation complexing, hydration and hydrolysis, neutralization reaction, reduce water-soluble difficult biochemical substances content, the alkalescence of waste water is reduced greatly; Also make simultaneously the heavy metal ion in the water obtain removing, the waste water after conditioning further makes dye decolored, COD reduction, Fe by desulfurication under anaerobic environment 2+Ion and reversal of cure product S 2-Generate insoluble sulfide, reduce S 2-Bio-toxicity and oxygen requirement, remaining amendment is further strengthened biochemical reaction in aerobic process section and microorganism coordinated, has improved the efficient of biochemical treatment.Waste water advanced treatment process also can be used for the tail water of dyeing waste water to be handled, but medicament expense height such as high-level oxidation technology such as ozone oxidation, working cost is high, and adsorption technology such as resin absorption or charcoal absorption all exist the difficulty of adsorbent reactivation.Therefore, existing dyeing waste water advanced treatment technology exists the shortcoming that technical and economic feasibility is not good, promote difficulty more.On the other hand, the advanced treatment of sewage and reuse have become current development trend.The advanced treatment of dyeing waste water and reuse not only can reduce total emission volumn, the protection water surrounding, and can improve water utilization rate, the conserve water resource realizes cleaner production, keeps economic Sustainable development.
The utility model content
The purpose of this utility model is to provide a kind of advanced treatment apparatus of dyeing waste water, and this device can not only guarantee that the dyeing waste water effluent quality is up to standard, realizes waste water recycling, and can increase the reuse water yield.
The scheme that the utility model solve the technical problem is: a kind of advanced treatment apparatus of dyeing waste water, described advanced treatment apparatus comprises ultra filtration unit, first reverse osmosis units and second reverse osmosis units, is connected in series between first reverse osmosis units and second reverse osmosis units.
As improvement, before the described ultra filtration unit automatic cleaning strainer is set, between described ultra filtration unit and described first reverse osmosis units security personnel's strainer is set.
As further scheme, between described ultra filtration unit and the described security personnel's strainer ultrafiltration is set and water tank, behind described second reverse osmosis units reverse osmosis is set and water tank.
Of the present utility model have a following beneficial effect:
(1) the utility model uses the advanced treatment apparatus of the assembled unit of ultrafiltration and reverse osmosis as dyeing waste water, makes the up to standard and water conditioning of water outlet, and the clear water that comes out can reuse.
(2) the utility model makes traditional first-stage reverse osmosis unit into the two-pass reverse osmosis unit, makes the dense water that comes out from first reverse osmosis units enter second reverse osmosis units again and carries out thickening filtration, has reduced the dense water yield, has increased the reuse water yield.
(3) the utility model utilizes the pre-treatment as reverse osmosis units of automatic cleaning strainer, ultra filtration unit and security personnel's strainer, makes complete assembly stable.
(4) the utility model is provided with ultrafiltration and goes out after water tank and reverse osmosis go out water tank convenient the collection and temporary water outlet.
Description of drawings
Fig. 1 is a process structure synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, of the present utility modelly comprise that successively automatic cleaning strainer, ultra filtration unit, ultrafiltration go out water tank, security personnel strainer, first reverse osmosis units, second reverse osmosis units and reverse osmosis and go out water tank.Automatic cleaning strainer is the pretreater of ultra filtration unit, and its filtering accuracy is 100 μ m, can remove impurity such as active sludge in the former water, suspended substance, algae, corrosion product and other molecule.Security personnel's strainer can prevent solid granule under high pressure to the destruction of reverse osmosis membrane, when the inlet outlet pressure differential of security personnel's strainer should be changed during greater than 0.1MPa.Former water after biochemical treatment passes through above-mentioned parts or unit successively.Be connected in series between first reverse osmosis units and second reverse osmosis units, the dense water that comes out of first reverse osmosis units enters second reverse osmosis units and carries out further thickening filtration, and the clear water that comes out of first reverse osmosis units then is delivered directly to reverse osmosis and goes out water tank.
Working routine of the present utility model is:
(1) the former current after biochemical treatment are through automatic cleaning strainer, and elimination is greater than the suspended substance of 100 μ m;
(2) former water is trapped through the organic pollutant greater than 1 μ m after the ultra filtration unit;
(3) former water enters first reverse osmosis units through security personnel's strainer after pressurize, the operating pressure of first reverse osmosis units is controlled at 1.5-1.8MPa, the dense water that comes out of first reverse osmosis units enters second reverse osmosis units and carries out further thickening filtration, and the clear water that comes out of first reverse osmosis units then is delivered directly to reverse osmosis and goes out reuse behind the water tank;
(4) the dense water that comes out from first reverse osmosis units enters second reverse osmosis units, and the operating pressure of second reverse osmosis units is controlled at 1.5-1.8MPa, enters reverse osmosis from the clear water that comes out of second reverse osmosis units and goes out reuse behind the water tank.
In above-mentioned technical process, all can be by the suitable control of relevant devices, device being realized the automatic operation of whole process flow, as for its concrete control method, can not need to pay creative work to those skilled in the art can implement.
In addition, ultra filtration unit and reverse osmosis units all can be arranged to two covers, and one is equipped with a usefulness, and these improvement do not have creativeness to the utility model.
