Description
Technical field
The present invention relates to a kind of waste water treatment process, particularly a kind of traditional Chinese medicine wastewater treatment process.
Background technology
Traditional Chinese medicine wastewater produces in washing the processes such as bubble boiling medicinal material, flushing, preparation mainly from production plant.Traditional Chinese medicine wastewater comprises the former medicine washing water in the production process, in the sewage that produces in the unit operations such as medicine original juice raffinate, filtration, distillation, extraction, production unit washing, floor wash water, steam condensate and the processing ion exchange resin acid-base solution and water etc.
Pollutent in the traditional Chinese medicine wastewater is broadly divided into two classes: a class is water miscible, and another kind of is insoluble.Water miscible pollutent main component is carbohydrate (polysaccharide is main), protein, xylogen, organic acid, resin, mucus fat, alkaloid, amino acid, steroidal, terpene, phenols, tannin, alcohol compound etc. and the nontoxic pigment introduced by the film-making operation; Insoluble pollutent main composition thing is the subparticle of silt, vegetable fibre (such as xylogen etc.), inorganic salt and other suspended substance etc.
The different pharmaceutical kind is different with production technique in the Chinese Traditional Medicine, and the waste water quality that produces and the water yield have very big difference, and because the replacement of products cycle is short, waste water quality, the water yield often fluctuate, and be extremely unstable.
Traditional Chinese medicine wastewater is that a kind of pollutant kind is various, the high concentration hard-degraded organic waste water of complicated, though this waste water is nontoxic harmful, because concentration is high, organic content is large, directly the discharging meeting causes severe contamination to environment.How effectively processing traditional Chinese medicine wastewater is Chinese herbal medicine industry development problem needing to overcome.
In wastewater treatment practice, be applied to the multiple water treatment technology, can be divided into according to action principle: four kinds of Physical, chemical method, physico-chemical processes and biochemical process.Wherein biochemical process is the method for the most effectively processing traditional Chinese medicine wastewater, because contain a large amount of polymer hardly degraded organic substances in the traditional Chinese medicine wastewater, biochemical process can be processed a large amount of polymer hardly degraded organic substance that decomposes in the traditional Chinese medicine wastewater effectively.
Chinese patent CN201110095687.8 has announced a kind of dormin production wastewater treatment technique, described technique mainly comprises pre-treatment, anaerobic treatment, backflow biochemical treatment step, the waste water treatment process that this patent is announced is applicable to the Pollutant levels height, organic content high wastewater treatment.When described patent technique is used for the traditional Chinese medicine wastewater processing, because the traditional Chinese medicine wastewater organism kinds is many, content is high, and traditional Chinese medicine wastewater not timing discharging, the waste water quality fluctuation is large.When organic content in the waste water is low, catalytic oxidation Aerobic Pond in the treatment process and the microorganism in the active sludge aerobic pond are owing to lack necessary nutrient matter, thereby easily cause the microorganism mortality, when the wastewater through organic matter impact load is high, lack enough microorganisms and come organism in the degrading waste water, cause water treatment effect undesirable.
Summary of the invention
The object of the invention is to overcome existing above-mentioned deficiency in the prior art, a kind of traditional Chinese medicine wastewater treatment process is provided.So that the traditional Chinese medicine wastewater treatment process can adapt to the processing of the traditional Chinese medicine wastewater of different CODCr values, improved processing efficiency and the adaptive faculty of traditional Chinese medicine wastewater treatment system.
In order to realize the foregoing invention purpose, the invention provides following technical scheme:
A kind of traditional Chinese medicine wastewater treatment process, comprise pre-treatment, two stage UASB anaerobic treatment and backflow biochemical treatment, described backflow biochemical treatment comprises the traditional Chinese medicine wastewater after processing early stage entered and enters the catalytic oxidation Aerobic Pond after process in the active sludge aerobic pond again and process, it is characterized in that, described active sludge aerobic pond and catalytic oxidation Aerobic Pond are also connected, when the traditional Chinese medicine wastewater CODCr concentration that enters processing when 500mg/L is above, described active sludge aerobic pond and the series operation of catalytic oxidation Aerobic Pond; When the traditional Chinese medicine wastewater CODCr concentration that enters processing at 500mg/L and when following, described active sludge aerobic pond and the parallel running of catalytic oxidation Aerobic Pond.
Preferably, in the pre-treatment of described traditional Chinese medicine wastewater treatment process, the pH value of traditional Chinese medicine wastewater is transferred to 8～9 deliver to again subsequent handling and process.
Traditional Chinese medicine wastewater carry out adjust pH to 8 first～9, can provide suitable condition for later anaerobic treatment and backflow biochemical treatment, thereby so that the traditional Chinese medicine wastewater treatment process is more effective.
Compared with prior art, beneficial effect of the present invention
Adopt traditional Chinese medicine wastewater treatment process provided by the invention, the active sludge aerobic pond is close with catalytic oxidation Aerobic Pond structure, and its handling principle all is to utilize microorganism wherein to consume organism in the traditional Chinese medicine wastewater.Show by contriver's great many of experiments and statistics, when organic concentration is high in the Chinese medicine waste water, described active sludge aerobic pond and the series operation of catalytic oxidation Aerobic Pond, the traditional Chinese medicine wastewater that organic concentration is high is reduced to below the 100mg/L through water outlet CODCr concentration after the biochemical treatment of two-stage.When Chinese medicine waste water COD Cr concentration is lower than 500mg/L, process traditional Chinese medicine wastewater if continue to adopt series system, microorganism in the catalytic oxidation Aerobic Pond will lack nutritive substance and die, so when Chinese medicine waste water COD Cr concentration is lower than 500mg/L described active sludge aerobic pond and the parallel running of catalytic oxidation Aerobic Pond, keep microorganism in described active sludge aerobic pond and the catalytic oxidation Aerobic Pond basic nutrition consumption, guarantee the survival of microorganism in described active sludge aerobic pond and the catalytic oxidation Aerobic Pond.
Improvement by above traditional Chinese medicine wastewater treatment process, so that this technique can adapt to traditional Chinese medicine wastewater discharging not timing, the uncertain characteristics of organic loading, can effectively process traditional Chinese medicine wastewater, thereby comprehensively improve the adaptive faculty of Waste Water Treatment, obtain good economic benefit and environmental benefit.
