Nitrification is inhibited by many organic compounds and also by ammonium nitrogen. A combined chemical and biological reactor has been developed in this study. In the reactor. concentrations of inhibitory compounds are maintained below the threshold of inhibition by the absoptive capacity of the active medium and transformed by the microorganisms grown on the medium.Zeolite is used as the midum against high concentration of ammonium nitrogen. Ion-exchange and biological nitrification mechanisms occur concurrently. and the reactor can response successfully to increase of loading. Activated carbon is used as the medium against inhibitory organic compounds. Nitrification activity can be kept high even in wastewater containing inhibitory compounds.The combined biological activated carbon and biological zeolite reactor was applied to treatment of scrubber-washed wastewater from sludge drying process. Successful treatment performance of both organics and nitrogen was accomplished. Operational and design parameters are proposed with the experimental data and mathematical model developed. Determination method of biomass grown on the attached mediums are estabished. And also screening method of the nitttrification-inhibitory organic compounds are proposed, and p-cresol was determined as the inhibitory compuonds contained in the scrubber-washed wastewater.

许多有机化合物和铵态氮都会抑制硝化作用。本研究开发了一种化学和生物组合反应器。在反应堆里。抑制化合物的浓度通过活性培养基的吸收能力维持在抑制阈值以下，并通过培养基上生长的微生物进行转化。沸石用作对抗高浓度铵态氮的培养基。离子交换和生物硝化机制同时发生。反应器能够成功地响应负荷的增加。活性炭用作对抗抑制性有机化合物的介质。即使在含有抑制性化合物的废水中也能保持较高的硝化活性。生物活性炭和生物沸石组合反应器应用于污泥干化过程中洗涤废水的处理。有机物和氮的处理均取得了成功。根据实验数据和开发的数学模型提出了操作和设计参数。建立了附加培养基上生长的生物量的测定方法。并提出了硝化抑制有机化合物的筛选方法，确定洗涤废水中的抑制化合物为对甲酚。
