富营养污水简易集成治理方法研究

Treatment of Eutrophic Water with Integrated Process Based on Immobilized Fly-ash-made Coagulant

以粉煤灰制成空心多功能污水处理材料,用该污水处理材料填充成五级絮凝降解过滤箱,在曝气协同下组成集吸附絮凝过滤与化学降解于一体的富营养水处理系统。在富营养水流量、曝气量分别为60L/h、40L/ m^3·h的工艺条件下,富营养水的可溶性盐、色度、COD_(cr)、BOD_5、氨氮、总磷等主要污染物指标分别降低93%、90%、95%、90%、86%和92%。该富营养水处理系统具有处理效果好、工艺简单和结构紧凑的特点。

Micro - hole material for treating waste water was made from fly - ash. A system of treatment for eutrophic water was combined by five - series trunks filled with this multi - functional material, and controlling - air - through. Under processing conditions of flow rate of 60L/h for eutrophic water, 40L/L · h for air, respectively, dissolvable salts, color density, CODe, BOD, ammoniated nitrogen and total phosphorous in the eutrophic water were cut down by 93% ,90% ,95% ,90% ,86% 和192%, respectively. Advantages of this system are good quality water obtained, simple treating process and integrated system structure.
