The Experimental Study On The Treatment Of Lincomycin Biowaste By Hydrolysis Acidification+UASB Process

As a largest producer country of antibiotic, the production of pollution has beenincreasingly obvious in front of people.To seek a safe and effective treatment method,is the key to solve the pollution caused by biowaste.A detailed analysis ofcharacteristics of lincomycin biowaste from Nanyang Pukang Pharmaceutical Co.After careful literature, taking a brief introduction about current treatment methodsand research progress of antibiotic biowaste. Through comparative analysis, selectingthe two-phase anaerobic digestion combined process which is hydrolytic acidification+UASB to deal with the lincomycin biowaste. In the Experimental Research, thestartup process and influencing factors of two reactor are the major research,decontamination performance of the single reactor、 combination process of tworeactors were investigated separately. Using the combined process to deal with thelincomycin biowaste is feasibleTaking37d to start hydrolysis acidification reactor by vaccinating secondarysettling tank sludge as seed sludge. When volume load reached10kg/m3d, theacidification rate of the effluent is22.38%, VFA reached114mmol/L, COD removalrate reached about20%, ammonia concentration reached1445.9mg/L. Releasing theammonia effectively and improving the biodegradability of waste by hydrolysisacidification reactor provide a good condition for the subsequent anaerobic reactor.Vaccinating2Lanaerobic granular sludge, the concentration of sludge were33.4gVSS/L, the startup of the UASB reactor last90day. The starting load is0.60kg/m3d,15%of the gradient to improve volume load, the final volume loadreach3.21kg/m3d. During the stable operation, the COD removal efficiencystabilized at around75%.The hydrolysis acidification reactor and the UASB were combined,using theeffluent of the hydrolysis acidification reactor as the influent of UASB, whichimprove the internal environment of the UASB reactor system, the pH inside the reactor dropped to about7.5, COD removal rate increased by5%, the final removalrate stabilized at around80%.Through comprehensive analysis, hydrolytic acidification+UASB reactorwhich is the combined process of two-phase anaerobic bacteria to treat thelincomycin biowaste residue performance Steadily.
