Abstract:   In humus soil activated sludge process the natural soil growing conditions were simulated. The soil microorganism culture system was appended to the traditional activated sludge system and the soil microorganisms with special functions were returned to the different positions of activated sludge process after they were enriched and activated. The project results showed that in the process nitrogen and phosphorus removal effects were enhanced, the sludge dehydration property was improved greatly, and the elimination of malodor was more important.

摘要:腐殖土活性污泥工艺是在污水处理系统中通过设置天然腐殖土复合矿物填料来模拟天然土壤生境条件,用于培养土壤微生物培养,在培养池内经过富集、活化后的具有特定功能的微生物回流到污水处理工艺不同部位,实现活性污泥工艺运行性能的强化。实践表明,该工艺可强化对氮磷的去除,降低污泥产率,使污泥脱水性能大大改善,同时实现了污水处理流程的无臭化。
