Abstract:
The treatment effects of the dosing of zero-valent iron(ZVI) and biological fillers on the hydrolysis acidi-fication of lincomycin wastewater has been investigated. The tests are carried out in three parallel reactors:the reac-tor for adding zero-valent iron(R1),the reactor for dosing bioreactors fillers(R2),and an ordinary reactor(R0). The results show that during the period of stable operation,the COD removing rates,acidifying rates of R1 and R2,and effluent B/C are all significantly higher than that of R0. The dosing of zero-valent iron and biological fillers both have enhancement effects on hydrolysis acidification,improving the wastewater biodegradability. Meanwhile,the resistance ability of their impact load of water quality is improved,as well.

摘要：
考察了零价铁和生物填料的投加对洁霉素废水水解酸化处理效果的强化作用，试验在3个平行的反应器中进行：投加零价铁的反应器（R1）、投加生物填料的反应器（R2）以及普通反应器（R0）。结果表明：在稳定运行时期，R1和R2的COD去除率、酸化率和出水B/C均明显高于R0。零价铁和生物填料的投加都对水解酸化起到了强化作用，提高了废水的可生化性，同时也都提高了反应器抗水质冲击负荷的能力。
