【摘要】 针对传统单独生物或者化学工艺除磷功效存在一定的局限性、除磷效果不稳定的特点,提出采用化学法辅助除磷与生物除磷联合处理的方案,即化学强化SBR生物除磷的试验方案。实验结果表明,采用FeSO₄作为强化生物除磷的同步沉淀剂,不但出水中磷的含量得到了有效的控制,使处理后的猪场废水能够连续达标排放,而且由于化学除磷过程中铁盐的混凝作用,也有利于出水中COD_cr及NH₃-N等污染指标的控制。更多还原

【Abstract】 Aiming at the localization and instability of the removal phosphorus by biological technics,suggest the experimental project combining chemical measure for assistant phosphorus by biological technics,suggest the experimental project combining chemical measure for assistant removing phosphorus and biological removing phosphorus,and make experiments to researching the practical sewage and manufacture establishment.The result indicates that this chemical measure for removing phosphorus is easy for application and can improve the phosphorus removal rate effectively.更多还原
