Description
The invention belongs to environmental protection technical field, relate in particular to a kind of shunting that trade effluent is carried out purifying treatment and can reach state-set standard discharging and administer technology.
At present, various trade effluents are handled the method for administering after all kinds of concentration that general employing will produce in the production process and water yield waste water inequality mixes.And the waste water that produces in all kinds of industry Industrial processes generally is divided into two big classes: the one, and participate in the waste water of separating after the Production Flow Chart or do the wash the water of producing reactor, this class water concentration height, the water yield is few, generally be that 1/10th of total draining water yield does not wait to one of percentage, concentration is tens times of total draining, even hundreds of times.Another kind of is the attached water of productive use that helps, as water coolant, water for cleaning etc.; This class water concentration low wash water is big, and concentration is that 1/tens of total draining concentration does not wait, and the water yield is general and total displacement is similar.Traditional improvement method is from total water port diversion comprehensive regulation mostly.
The industrial trade of waste discharge is a lot of in the production, as papermaking, chemical industry, print and dye, brewage (liquor, beer etc.), pharmacy, process hides, meat processing etc.
Black liquor is the high concentration water in the paper waste, and concentration is that ten of total draining is arrived twenty or thirty doubly, and COD does not wait at 3-10 ten thousand; The water yield is that ten of total displacement arrives twenty or thirty/one.The middle section water paper machine white water water yield is big, and concentration is low, when COD fully extracts at black liquor, only has between the 400-500mg/l when 95% left and right sides as extraction yield.
Chemical industry waste water, high concentration water wherein separates from process of product development; Any Chemicals are produced the rate that obtains that forms all can not 100%, and residuum comes out with water sepn mostly.This water COD does not wait to more than 20 ten thousand up to tens thousand of, but the water yield seldom, is 1/tens of integrated water.Generally between 1200-2500, other waste water are water coolant, cleaning water to integrated water COD concentration, and COD is about 200 in the water, but the water yield is very big.
In the Chinese patent medicine industry waste water, its high concentration water is the workshop section's waste water such as alcohol precipitation that extract in the water and the course of processing, it is a water of doing the wash the extract container, sometimes up to ten or twenty ten thousand, mean value is also about seven, 80,000, but general ten or twenty ton of its water yield, and water coolant, rinse water COD are about 180, the water yield is very big, should have about 1000 tons mutually.
In the beer brewery water, brewing room and fermentation plant waste water COD do not wait up to 6000-12000mg/l, and low concentration of water COD does not wait at 300-500mg/l, produce ton beer generation waste water 5-30 ton and do not wait, different and different with processing unit, total the high concentration water accounts for five to 1/10th of its wastewater flow rate.
The water quality and quantity of industry waste water situation such as other industry such as process hides, meat processing, printing and dyeing and above-mentioned every profession and trade constitutes close.
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of initial cost and running expense is low, floor space is little, but the novel process that is suitable for advanced treatment, process qualified discharge easy to control, does not produce the industrial waste water purifying of secondary pollution is arranged.
The object of the present invention is achieved like this, and its technological process is as follows:
At first high-concentration organic industrial waste water is carried out the shunting processing of high concentration water and low concentration wastewater.Whichever industry and concrete that producer, its high-concentration waste water all is a certain or certain several two sections formation and have special pipeline to discharge, and accomplishes so it is shunted out easily.
The second, shunting is handled the back high concentration water is carried out materialization processing and biochemical treatment.Because materialization effect clearance height (can exceed about 15-20%) when generally specific concentration is low under the high situation of concentration.From to pharmaceutical factory of traditional Chinese medicine's waste water, papermaking, black liquor, fine chemistry industry waste water, dye result such as refining water etc., COD is four or five ten thousand when above, the materialization clearance between 60～72%, if same waste water COD at 3000 clearances when following between 45～53%, used flocculation agent should be selected.In addition, most COD is removed in first materialization, for subordinate's biochemical treatment has reduced load, has reduced intractability.Materialization processing and biochemical treatment process can be according to the different mining of water quality with different first last handling processes.Therefore also may adopt the biochemical earlier technology of materialization more sometimes according to the water quality difference.This is not under the extra high situation at waste strength generally, as beer waste water middle and high concentration water COD about 10,000.At this moment also can adopt the materialization again of first biochemistry, help biochemical back mud and remove.
The biochemical treatment in this step can be anaerobism or aerobic also amphimicrobe processing.
The 3rd, the high concentration water is carried out carrying out materialization processing or biochemical treatment again after materialization and the biochemical treatment with after low concentration of water is mixed last qualified discharge.High concentration water after fully handling is entered in the low concentration of water by the water yield ratio of two class water.Mix back COD generally speaking and have only 250～300mg/l.Such water generally can make water outlet COD between 120～150mg/l with simple chemical flocculation.According to the receiving water body difference, when requiring processing horizontal higher, can handle the high concentration water more abundant, to adapt to the requirement that a materialization of last mixing water can reach discharging; Because of high concentration water's the water yield is little, depths reason target is more readily accessible.
The present invention has following positively effect:
One, shunting is handled and is helped improving the materialization treatment effect.For the high concentration water, the materialization clearance that increases that materialization is handled with concentration increases; And the flocculation agent injected volume descends for the unit consumption by every 1000mg/l COD.As COD is that the papermaking water of 3000mg/l fully flocculates with the aluminium based flocculating agent, and consumption is 1.5 ‰, and clearance is 55%, and to the black liquid of COD30000mg/l, same flocculation agent consumption is 7～8 ‰, and clearance is 65%～70%.More obvious to this effect of traditional Chinese medicine wastewater.
By above-mentioned shunting as can be seen, materialization effect combination treatment is much better, and this can save running expense greatly.
Two, shunting is handled the high concentration water being carried out materialization earlier and is handled and help next step biochemical treatment, alleviating the biological treatment load, can reduce the anaerobism time concerning anaerobic biological treatment, thereby the anaerobic reactor volume is reduced, and can save initial cost greatly.Original high concentration water's water yield is just very little, just can reduce much with the anaerobic treatment reactor volume, and the load reduction reduces action time makes volume reducing again.The initial cost that double effect reduced is very considerable.Aerobic treatment also there is same considerable effect.Construction investment can save 2/3 to 3/4.
Three, shunting is handled and can be saved facility floor space 1/3 to 1/2 than the combination treatment of generalized case.
Four, the positively effect handled of shunting be suitable for up to standard.Because high concentration water's water yield is little, be subjected to the effect of reactor volume size-dependence little with the depths reason, so just can fully handle, to the end with the final processing of low concentration of water mixing energy requirement up to standard.If the processing integrated water, often because the water yield is big, reactor volume can not enlarge because of needs, or cost is high and can not implement.
Fig. 1 is a process flow sheet of the present invention.
The invention will be further described below in conjunction with embodiment.
Embodiment 1, is example to produce 400,000 SHUANGHUANGLIAN oral liquid Chinese patent medicine pharmaceutical factory waste water daily.Day row high concentrated organic wastewater 18～20t, COD about 80,000, low concentration wastewater 1000t, COD is about 170.About mixing water COD1840mg/l.It is COD150mg/l that environmental administration requires emission standard.
1, high-concentration waste water is to extract the workshop discharging.Three kinds of waste water are wherein arranged: alcohol precipitation water, concentrated waste water and extraction waste water.Discharge through three mouths of pipe, these three kinds of high-concentration waste waters are focused on one, this water materialization is handled clearance and (drop into aluminium based flocculating agent 2%) about 65%, and COD drops to about 2.8 ten thousand.
As use conventional method, and be 1840 to mixing water COD, use same flocculation agent, dosage is 1.7 ‰, clearance has only 50%.Total Water is in 1000t, and COD presses 1800mg/l, and the 1.7t flocculation agent removes COD900kg.And use shunting, high concentration water's water yield to press 20t, and COD uses same flocculation agent in 80,000, and dosage is 2%, and clearance is 65%, and the 0.4t flocculation agent is removed 1040kgCOD, and economic benefit is very considerable.
2, the water after the materialization carries out biochemical treatment.The first step is acidifying, 24 hours treatment times, and clearance 20%, COD reduces to about 2.2 ten thousand.At this moment the biodegradability of water improves, and reactor volume only 20 is as wanting 700 without the shunting process reactor volume.
3, available amphimicrobe is handled (energy-conservation) also available anaerobism or aerobic treatment.Facultative processing 48 hours, clearance is at 70-80%; Anaerobic treatment is more than 72 hours, and clearance is at 75-80%; Aerobic treatment 12-16 hour, clearance was about 75%.When COD drops to 10,000 when following (generally can handle about 4000), mix with low concentration of water and do last the processing.Reactor volume 40～60, as shunting processing, the reactor volume anaerobism wants 3000, aerobicly wants 800.
4, the high concentration water after abundant the processing mixes back integrated water COD concentration in proportion at 200～300mg/l with low concentration of water, and water outlet COD is between 100～150mg/l behind chemical flocculation (middle dose is 0.4 ‰), and dosage is little, and processing costs is low.
