Abstract
The invention belongs to the technical field of medical gauze processing, and particularly relates to a medical gauze bleaching and rinsing wastewater recovery use process. The medical gauze bleaching and rinsing wastewater recovery use process comprises steps in the following sequence: when a program is in prewashing, controlling start of a reuse water pump 1, opening valves of control valves #4 and #8, filling reuse water to operate, conducting the beginning 6 min of overflow rinsing 1, controlling start of the reuse water pump 1, opening the valves of the control valves #4 and #8, and filling the reuse water to conduct overflow rinsing. The medical gauze bleaching and rinsing wastewater recovery use process has the benefits that the water use amount can be reduced by 1/3 as compared with the conventional technology, the product quality is not influenced, better environment-friendly benefit is achieved, and along with the improvement of the price of tap water, the benefit of cost reduction is more and more obvious, the wastewater treatment amount is reduced, and then the treatment cost is also reduced.
Description
Technical field
The invention belongs to hospital gauze processing technique field, be specifically related to a kind of hospital gauze bleaching washing waste water and reclaim operation.
Background technology
Gauze is the cotton goods that a kind of longitude and latitude is sparse, textile hospital gauze need be processed through bleaching process, textile hospital gauze bleaching process: prewashing-bleaching-washing-neutralization-washing-pH value adjustment, the current equipment using of the same trade does not possess hospital gauze bleaching washing waste water and reclaims use function, this project is with high content of technology, though reclaiming, waste water has good economic benefit and social benefit, but invest larger, operation is controlled complicated, therefore hospital gauze bleaching washing waste water does not reclaim use substantially, causes the waste of water resource.
Summary of the invention
The present invention is in order to make up the defect of prior art, provide a kind of to reach when reducing water quantity, do not affect product quality, and have good environmental benefit, reducing wastewater treatment quantity and processing cost is the hospital gauze bleaching washing waste water recovery operation on order ground.
The present invention is achieved through the following technical solutions:
Hospital gauze is bleached washing waste water and is reclaimed an operation, comprises following order step: prewashing-bleaching-intensification washing-overflow washing 1-neutralization-overflow washing 2-pH value adjustment-complete and hang cylinder-waste water recovery use;
1, prewashing: fill recycle-water normal temperature running after 15 minutes draining to cold wastewater disposal basin;
2, bleaching: fill hot soft water running and feed in raw material: the hydrogen peroxide that uses content 27.5%, in bleaching liquor, the concentration of hydrogen peroxide is 20 grams of every premium on currency content, the sheet alkali that uses content 99%, the concentration of bleaching liquor is 10 grams of every premium on currency content, refining agent 2g/l, dispersant 3g/l, hydrogen peroxide stabilizer 3g/l, be warming up to 120 degree, temperature retention time 50 minutes, be then cooled to 90 degree after draining to thermal wastewater pond;
3, heat up and wash: fill hot soft water normal temperature running to 75 degree, temperature retention time 10 minutes, then draining is to thermal wastewater pond;
4, overflow washing 1: fill after recycle-water water transport turns, continue water-filling, by top Overflow drainage to cold wastewater disposal basin, after 5 minutes, change fill cold soft water and continue to be washed to 15 minutes after by bottom discharge to reuse pool;
5, neutralization: fill cold soft water running and feed in raw material: 7 kilograms of acetic acid, be warming up to temperature 50 degree, be incubated 20 minutes, rear draining is to cold wastewater disposal basin;
6, overflow washing 2: fill after cold soft water running, continue water-filling, by top Overflow drainage, to reuse pool, the draining of turning round after 20 minutes is to reuse pool;
7, pH value adjustment: fill cold soft water running and feed in raw material: after 2 kilograms of normal temperature of acetic acid turn round 20 minutes, draining is to reuse pool;
8, complete and hang cylinder draining;
9, waste water reclaim to be used: by the waste water of discharging in overflow washing 2, the waste water that pH value adjustment is discharged, complete and hang the waste water of discharging after cylinder and be collected into reuse pool by pipe special; While carrying out prewashing, control reuse water pump 1 and start, and open control valve #4, #8 valve, be filled with recycle-water running, carry out overflow washing 1 first 6 minutes, control reuse water pump 1 and start, and open control valve #4, #8 valve, be filled with recycle-water overflow washing.
The invention has the beneficial effects as follows: a kind of hospital gauze bleaching of the present invention washing waste water reclaims operation and can reduce water quantity 1/3 than conventional art, but do not affect product quality, there is good environmental benefit, raising along with running water price, the benefit reducing costs can be more and more significant, reduce wastewater treatment quantity, thereby also reduced processing cost.
Accompanying drawing explanation
accompanying drawing 1 is a kind of hospital gauze bleaching of the present invention washing waste water recovery operation flow chart.
The specific embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present invention.This is invented a kind of hospital gauze bleaching washing waste water and reclaims operation, comprises following order step:
1, prewashing: fill recycle-water normal temperature running after 15 minutes draining to cold wastewater disposal basin;
2, bleaching: fill hot soft water running and feed in raw material: hydrogen peroxide 27.5%, 20g/l, sheet alkali 99%, 10g/l, refining agent 2g/l, dispersant 3g/l, hydrogen peroxide stabilizer 3g/l, be warming up to 120 degree, temperature retention time 50 minutes, be then cooled to 90 degree after draining to thermal wastewater pond;
3, heat up and wash: fill hot soft water normal temperature running to 75 degree, temperature retention time 10 minutes, then draining is to thermal wastewater pond;
4, overflow washing 1: fill after recycle-water water transport turns, continue water-filling, by top Overflow drainage to cold wastewater disposal basin, after 5 minutes, change fill cold soft water and continue to be washed to 15 minutes after by bottom discharge to reuse pool;
5, neutralization: fill cold soft water running and feed in raw material: 7 kilograms of acetic acid, be warming up to temperature 50 degree, be incubated 20 minutes, rear draining is to cold wastewater disposal basin;
6, overflow washing 2: fill after cold soft water running, continue water-filling, by top Overflow drainage, to reuse pool, the draining of turning round after 20 minutes is to reuse pool;
7, pH value adjustment: fill cold soft water running and feed in raw material: after 2 kilograms of normal temperature of acetic acid turn round 20 minutes, draining is to reuse pool;
8, complete and hang cylinder draining;
9, waste water reclaim to be used: by the waste water of discharging in overflow washing 2, the waste water that pH value adjustment is discharged, complete and hang the waste water of discharging after cylinder and be collected into reuse pool by pipe special; While carrying out prewashing, control reuse water pump 1 and start, and open control valve #4, #8 valve, be filled with recycle-water running, carry out overflow washing 1 first 6 minutes, control reuse water pump 1 and start, and open control valve #4, #8 valve, be filled with recycle-water overflow washing.
Water saving quantity:
