Research On Pilot Test Of Treatment Of Arginine Bio-Pharmaceutical Wastewater

With the development of the pharmaceutical industry in our country, Much attention has been paid to the pollution of the wastewater treatment and the relevant solutions. There are various organic pollutants containing in the wastewater, among which most are difficult to begraded or would have inhibition effct on microorganism. And it’s hard to get the anticipating result if the traditional methods and techniques are used to dispose the wastewater. On the basis of the related studies both at home and abroad, taking the wastewater from a pharmaceutical factory in Xintai as the disposal object and the writer made a research on the coagulation, anaerobic, aerobic, biological activated carbon combined process in pharmaceutical wastewater treatment.This research project is divided into two parts:The first part is a small test, discusses the treatment effect and the process parameters of the coagulation system, biological treatment systems and biological activated carbon system, which mainly focused on the technical theory. The second part is a pilot test, this test made the coagulation treatment, anaerobic baffled reactor process, aerobic activated sludge process and biological activated carbon process as a complete system, exploring more practical engineering parameters, and in-depth studied in shock load which is caused by batch of arginine fermentation.Experimental results show that:This process can effectively achieve the removal of pollutants and can withstand a certain degree of shock loading when the arginine wastewater has the character of high NH3-N, large turbidity and intermittent effluent. The Anaerobic Baffled Reactor in anaerobic part and the loop reactor technology in biological activated carbon part both achieved good results. Pilot-scale test is proved that using this technique can effectively reduce COD and NH3-N which is the major pollutants in wastewater.When the influent CODcr, NH3-N and colority were1603mg/L,372mg/L and1280times, the enfluent CODcr, NH3-N and colority were81mg/L,18mg/L and32times, the chief targets better than GB21903-2008.This technology has small footprint, low investment, low operation cost and easy management chatacter. This paper confirmed the water treatment technology was feasible by system tests, which provided the valuable theory reference for engineering application.
