The Research On The Process Of Amino Acid Seweage Treatment

Pharmaceutical industry to use chemical methods to organic or inorganic materials through a certain process of production of pharmaceutical raw materials or final response to the Pharmacy, its products have a short replacement cycle, product variety and characteristics of the production process with a product will often change. Medical wastewater is often high concentrations of organic contaminants, pollutants in complex, while large amounts of toxic waste water containing harmful organic contaminants and some biological inhibitory factor, can cause direct discharge of water pollution. Therefore, pharmaceutical waste water pollution control has attracted much attention.At present, the amino acid medical treatment, at home and abroad can not yet mature in general to promote the treatment process.Developed countries, mainly pre-treatment and dilution of strong oxidizing aerobic biological treatment process. The processing efficiency of such treatment technology reliable, but expensive to run. Some conventional physical and chemical processes are often used in the pharmaceutical industry, wastewater treatment, such as coagulation and sedimentation processes, electrolytic processes, chemical oxidation process. Widely used biological treatment process of anaerobic hydrolysis and aerobic treatment process, but for different types of wastewater treatment results vary widely.The wastewater of Yichang Pharmaceutical Co.,LTD which product amino acid was high concentration.The ratio of wasterwater BOD5/CODcr was 0.57, which was good biodegradability of industrial wastewater.Acidification can be used, two aerobic treatment and advanced treatment process.the treatment process of wastewater is "the wastewater→grille→regulating tank→first sedimentation tank→anaerobic biological treatment tank→CASS tank→CAF device→the middle tank→BAF immobilized microorganisms→coagulation and sedimentation tanks→the exit water.The amino acid wastewater by Physical Medicine conducted a test of coagulation. Determined by coagulation test mixture of organic and inorganic coagulant dosage: PFS was 200mg/L, Polyacrylamide (PAM) dosage of 3mg/L.The designed treatment water amount was 4000t/day,the entering water CODcr was 14000mg/L, BOD5 was 8000mg/L,SS was 6700mg/L,NH3-N was 890 mg/L,the exit water CODcr was 95.3mg/L,BOD5 was 32.8mg/L,SS was 35.1mg/L,NH3-N was 18.3 mg/L,and the exit water index can reached the state "Discharge standards of water pollutants for pharmaceutical industry Fermentation products category" (GB21903-2008).Yichang Pharmaceutical Co.,LTD which product amino acid used in pharmaceutical wastewater treatment processes for wastewater treatment of similar reference.
