Abstract
The utility model discloses a kind of being carried out by using ion-exchange resin regenerated waste water and be separated the system obtaining low concentration soda acid, it comprises a set of 4 switch valves, article 2, separate pipe trench, 3 wastewater disposal basins, it is characterized in that described system comprises the system that 2 switch valve compositions are separated acid solution, alkali lye and flushing water, article 2, separate pipe trench transport wastewater, acid or alkali lye, 3 wastewater disposal basins storing wastewater, low concentration acid, low-concentration alkali liquor respectively, a set of control system by-pass valve control switches; During regeneration, collect waste water when system is rinsed, when system enters acid and displacement, collect low concentration acid, when system enters alkali and displacement, collect low concentration alkali, by this system, regenerative wastewater is separated into three parts: the acid of waste water, low concentration, low-concentration alkali liquor, can reuse be distinguished.
Description
Technical field
The utility model relates to Recycle Technology of Waste Water, and being specifically related to a kind of can will be the device that regenerative mixed acidic and alkaline waste water is separated into waste water, low concentration acid, low concentration alkali three class medium originally.
Background technology
At present, existing ion exchange resin regeneration system, regenerate the waste liquid of each stage discharge, comprise and just wash, the waste water of backwash stage, enter the acid solution in acid and displacement stage, enter the alkali lye in alkali and displacement stage, all mix, after hybrid reaction, become the brine waste of about concentration 3-5%, because its salt content is high, cannot direct reuse, can only arrange outward, becoming cannot the waste water of reuse.
Current Operation system setting does not all consider the reuse of waste water, is for target with simple mixed collection.
But current environment protection emission requires strict, and also more and more higher to the requirements of comprehensive utilization of water resource, traditional regenerative wastewater mixed collection is not suitable with environmental requirement.
Utility model content
For existing regenerative system above shortcomings, the utility model can provide a kind of just being carried out in the generation stage by using ion-exchange resin regenerated waste water to be separated the system obtaining low concentration soda acid.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of being carried out by using ion-exchange resin regenerated waste water is separated the device obtaining low concentration soda acid, it comprises two program-controlled valves be arranged on middle discharge pipe, article two, separate and collect pipe trench, the waste liquid pool of the acid of three storing wastewater, low concentration, low concentration alkali, two program control switch valves and corresponding program:
Two program-controlled valves on described middle discharge pipe, are specifically arranged on ion-exchanger discharging of waste liquid pipe, can be middle combs, or positive comb, specifically see the position of interchanger regeneration liquid waste outlet.
Separate for described two and collect pipe trench, independent setting.Article one, pipe trench is for receiving Normal wastewater, straight-through wastewater disposal basin; An other pipe trench is used for receiving containing acid containing alkali waste water, the generation because acidic and alkaline waste water generally staggers, so share a pipe trench.
Three described wastewater disposal basins, are respectively used to storing wastewater, low concentration acid, low concentration alkali, and sour paper mill wastewater enters the technique decision of alkali concn into acid according to regenerating, generally fluctuate within the scope of 2-4%.
Described wastewater disposal basin switch valve, is arranged on wastewater disposal basin import, when system enters acid solution, opens acid bath inlet valve, and the acid solution of generation is from flowing into acid bath; When system enters alkali lye, open alkali lye pond inlet valve, the alkali lye of generation is from flowing into alkali lye pond.
Described program, controls respective valves, to receive waste water, acid or alkali at different regeneration stage.
The advantage of the utility model system is: by the high-salt wastewater produced during originally regeneration, is collected by valve transfer and special pipe trench, pond, becomes less salt waste water, low concentration acid, low concentration alkali three kinds can the material of recycling.
The utility model is widely used in water treatment field ion exchange system, can reach the target turned waste into wealth.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is the utility model ion-exchanger regenerative wastewater drainage system schematic diagram;
Fig. 2 is three wastewater disposal basin schematic diagrames of the utility model system;
Detailed description of the invention
Examples of implementation: this example provides a kind of being carried out by using ion-exchange resin regenerated waste water to be separated the system obtaining low concentration soda acid, it comprises the ion-exchanger body 1 in Fig. 1, inlet valve 2, waste liquid dump valve 3, waste water dump valve 4, acid & alkali liquid dump valve 5, wastewater collection pipe trench 6, acid & alkali liquid collects pipe trench 7;
It also comprises the wastewater collection pond 11 in Fig. 2, low concentration acid collecting pit 12, low concentration alkali collecting pit 13, wastewater collection pipe trench 14, and low concentration soda acid collects pipe trench 15, low concentration acid collecting pit inlet valve 16, low concentration alkali collecting pit inlet valve 17;
When enter in inlet valve 2 be water time, programme-control waste water dump valve 4 is opened, acid solution dump valve 5 cuts out, and waste liquid, by water inlet inlet valve 2-ion-exchanger body 1-waste liquid dump valve 3-waste water dump valve 4-wastewater collection pipe trench 6, finally collects Fig. 2 wastewater collection pond 11;
When enter in inlet valve 2 be acid solution time, programme-control waste water dump valve 4 cuts out, acid & alkali liquid dump valve 5 is opened, waste liquid collects the low concentration acid collecting pit inlet valve 16 in pipe trench 7-Fig. 2 by water inlet inlet valve 2-ion-exchanger body 1-waste liquid dump valve 3-acid & alkali liquid dump valve 5-acid & alkali liquid, finally collect Fig. 2 low concentration acid collecting pit 12;
When enter in inlet valve 2 be alkali lye time, programme-control waste water dump valve 4 cuts out, acid & alkali liquid dump valve 5 is opened, waste liquid, by the low concentration alkali collecting pit inlet valve 17 in water inlet inlet valve 2-ion-exchanger body 1-waste liquid dump valve 3-acid & alkali liquid dump valve 5-wastewater collection pipe trench 7-Fig. 2, finally collects Fig. 2 low concentration alkali collecting pit 13;
When the utility model uses, by controlling the switch of the different valve of different step, by waste water, low concentration soda acid natural separation, collect different Pondings.
The utility model is widely used in the ion exchange regenerant waste water system of water treatment field, by valve transfer, the regeneration liquid waste of mixing originally can be separated into three kinds of media, reuse respectively.
