生物增效技术在电子行业废水处理中的应用

Application of biological multiplication and biological products in electronic wastewater treatment

研究了生化系统在投加某公司倍活硝化菌等微生物制剂后,系统COD的去除效率和硝化反应的启动时间情况,验证该公司的微生物制剂恢复生化系统的功能。研究表明:在进水COD达到300mg/L,NH3-N达到30mg/L左右的生化系统中加入倍活硝化菌、倍活COD菌等微生物制剂,可以使出水COD≤50mg/L,NH3-N≤5mg/L,并且增强了系统的抗冲击能力。

This paper studies the removal efficiency of COD and the start-up time of nitrification reaction in biochemical system after adding biologics such as biologics of our company, so as to verify the function of biologics of our company to restore biochemical system. The results show that when the COD of influent reaches 300 mg/L and NH3-Nreaches about 30 mg/L, the biological agents such as live nitrifying bacteria and live cod bacteria are added to the biochemical system, the COD of effluent is less than 50 mg/L and NH3-Nis less than 5 mg/L, and the impact resistance of the system is enhanced.
