Abstract
A kind of treatment process of drained waste water in antibiotic production.Feature of the present invention is, the waste water of production of antibiotics discharging earlier through slag pass through again/or without the flue dust adsorption treatment, after other biochemical method is handled, waste water COD can reach≤emission standard of 100mg/l.
Having solved drained waste water in antibiotic production can't handle with general biochemical method, the difficult problem that COD exceeds standard and discharges.
Description
The invention belongs to field of environment protection, is a kind of three industrial wastes improvement technology, the treatment process of drained waste water in antibiotic production in particularly a kind of medicine industry.
Along with development of science and technology, administer waste residue, waste gas and the waste water of industrial discharge, the human physical environment of depending on for existence of protection is paid attention to for people day by day.Chinese government regulation, COD(Chemical Oxygen Demand, i.e. chemical oxygen demand in the trade effluent) ultimate value be≤100mg/L.
Reduce COD in industrial wastewater, use biochemical treatment process usually, wherein activated sludge process or Unareobic fermentation are particularly commonly used.These industrialized biochemical procss for treating waste water, not only expense is economized, and the mud after handling can also be as producing biogas and fertilizer, and fully utilizes.
More than two methods, all be to rely on natural microorganism to decompose COD and other impurity by serial food chain.They are suitable for commonly industrial wastewater, and are not suitable for the improvement of drained waste water in antibiotic production in the medicine industry.In the waste water of production of antibiotics (it is Broad spectrum antibiotics production) discharging,, can cut off the biochemical system of microorganism, suppress it and grow, thereby cause the biochemical process failure of disposing of sewage owing to contain the small portion of residual microbiotic.Production of antibiotics factory can't utilize microbial process to handle its sewage, and this is its basic reason.The waste water of the production of antibiotics factory discharging that exceeds standard at present, not only enterprise need pay huge blowdown and imposes a fine, and environment is caused unnecessary pollution, leaves a legacy of trouble to national economy.
Purpose of the present invention is exactly the treatment process of looking for a drained waste water in antibiotic production inexpensive, that be suitable for industrial applications.
Task of the present invention is finished as follows: in production of antibiotics factory, in order to sterilize and the needs of processing condition, having steam boiler usually, much is coal firing boiler wherein, and slag and flue dust are arranged, and needs discharge after the tap water wet processing.By test, we are with our factory's drained waste water in antibiotic production (remaining Broad spectrum antibiotics content: 400-600 units per ml COD11000-15000mg/L) replace tap water wet processing slag and flue dust.After treatment, remaining Broad spectrum antibiotics content is reduced to 0 units per ml in the waste water, and COD reduces to 7200-10500mg/L.Handle through other biochemical method (for example activated sludge process or Unareobic fermentation), waste water COD can be up to standard again, conform with national regulation≤emission standard of 100mg/L.
Slag after the processing and flue dust are that local building materials factory is as prepared using.
Used slag is the scorching hot slag of just having discharged from the boiler slag tapping equipment.Adsorb saturated slag after the stack gas thorough drying, also can reach effect same.
Waste water after slag treatment, before handling again with other biochemical method again, can through/or handle without flue dust.
Feature of the present invention is: the waste water of production of antibiotics discharging earlier through slag again through/or handle without flue dust, after other biochemical method handle.
Treatment process provided by the invention need not to increase equipment.
1, promptly at the original slag tapping equipment of coal firing boiler place, replace the tap water of former usefulness with waste water, make its residues of antibiotics in scorching hot slag absorption waste water.
2, use former smoke abatement device, with through the waste water after the slag absorption, replace tap water, be used to cause moisture film, flue dust contacts with moisture film, can continue to adsorb residues of antibiotics in the wastewater membrane.
3, through in the waste water after twice absorption, residues of antibiotics eliminates, and COD has removed 30%.
4, pass through activated sludge process biochemical treatment (our factory with two aeration tanks, two biological towers) again, waste water COD reaches≤100mg/L, reaches discharging standards.
Method provided by the invention, main effect is to remove residues of antibiotics in the medicine industry drained waste water in antibiotic production, and biochemical treatment process can be carried out.As for the scale of biochemical treatment, decide on COD amount in wastewater flow rate and the waste water.
This law is also used the occasion of microbial fermentation applicable to other industry (as foodstuffs industry etc.).
(embodiment) aforesaid method, result is as follows:
(note)
1, COD analytical procedure is to use potassium dichromate process.
2, the antibiotic remains analysis method is " antibiotic-microbial assay " with the Chinese Pharmacopoeia regulation.
Claims (5)
1, a kind of treatment process of drained waste water in antibiotic production, feature of the present invention be, the waste water of production of antibiotics discharging earlier through slag pass through again/or without the flue dust adsorption treatment, after other biochemical method handle.
2, method according to claim 1 is characterized in that used slag is scorching hot.
3, method according to claim 1 is characterized in that waste water after slag treatment, can pass through again/or handle without flue dust.
4, method according to claim 3, it is characterized in that through slag treatment again through/or handle without flue dust after waste water, handle through other biochemical method again.
5, method according to claim 4.It is characterized in that described other biochemical method can be activated sludge process or Unareobic fermentation.
