Description
Technical field
The utility model relates to a kind of biochemical processing of pharmacy waste water; Specifically be the equipment of realizing the advanced treatment of pharmacy waste water through the synergy of the reversal of cure of synchronous biological denitrification, anaerobism product methane and denitrification of autotrophic organism technology, be applicable to pharmacy waste water processing up to standard and regeneration.
Background technology
Pharmacy waste water has that organic pollutant category is many, concentration is high, complicated component and contain characteristics such as a large amount of vitriol, residual pharmacy and degradation product thereof, is the organic waste water hard to manage of generally acknowledging.The water quality of pharmacy waste water changes because of the difference of production technique, the NH of typical pharmacy waste water
4 +-N concentration is 600～3000mg/L, and COD concentration is 4000～50000mg/L.
National environmental protection portion has issued the new standard of pharmaceutical industry sewage discharge-" a fermentation type pharmaceutical industry pollution discharge standard " (GB21903-2008) on August 1st, 2008, in July, 2010 the formal new standard of implementing.New standard regulation: NH
4 +-N＜35mg/L, TN＜70mg/L, COD＜120mg/L.According to above-mentioned criterion calculation, nitrogen and COD clearance need reach more than 95% in the pharmacy waste water.And existing pharmacy waste water treatment technology, the high density pollution material in far can not cost-effective removal pharmacy waste water, the treatment technology of researching and developing advanced pharmacy waste water is very urgent.
Ammonia nitrogen removal on the at present present actual engineering of pharmacy waste water mainly adopts with physicochemical techniques and comprises mixed flocculation, chemical precipitation, ammonia stripping, membrane filtration and absorption etc.; Cause that working cost is high, energy consumption is high owing to add chemical reagent; And nitrogen pollutant transferred to the temporary transient water outlet qualified discharge of realization in mud and the air from water; Do not realize from environment, not removing fully, big to the intractability of the mud that produces in the treating processes and liquid concentrator, brought the secondary pollution problem also very seriously.Biological denitrificaion has economy, efficient, continuable advantage; Can economize subsequent treatment process such as pretreatment technology such as deammoniation stripping and high pressure r-o-; Construction and working cost that pharmacy waste water is handled all reduce by 20% at least; And do not have secondary pollution deposits yields such as liquid concentrator, really realize continuable pharmacy waste water biochemical treatment.
Biological denitrificaion is to remove NH
4 +The effective way of-N, but work as NH
4 +When-N concentration was higher, the activity generation had strong inhibitory effects to nitrifier can't be carried out nitrification.For high density, the complicated organic removal of composition in the pharmacy waste water, select anaerobic biological process as pretreatment technology usually, but the voltaile fatty acid VFA that produces in the Anaerobic processes is to NH
4 +Nitrated can the generation of-N suppressed.
It is thus clear that; Because pharmacy waste water water quality and Changing Pattern are understood deficiency or are not given enough attention; Municipal sewage treatment technology and design variable are indiscriminately imitated on the pharmaceutical wastewater treatment process blindly, not only processing costs is expensive, and water outlet at all can't be up to standard.Existing pharmacy waste water treatment technology does not have the good removal coordinating and unifying with organic matter removal and nitrogen; Normally remove organism earlier; Then remove nitrogen, the result causes the organic carbon source of biological denitrification not enough, and water outlet TN far can not reach new control criterion.Exploitation is fit to the efficient collaborative degree of depth removal organism of pharmacy waste water water quality characteristics and the biochemical technology equipment of nitrogen, is the key of pharmacy waste water qualified discharge and regeneration.
