摘　　要：针对广州市河涌治理的紧迫性、复杂性以及传统治理方法的缺陷与不足,本文介绍了一种利用生物修复技术原位治理广州黑臭河涌污染的方法。该方法通过河道曝气增氧、投放微生物菌剂、底泥生物修复和设置生物巢系统等步骤和措施,控制和消除河涌外源和内源污染,净化河涌水质,提高水体自净能力,达到消除黑臭、消除河道底泥的目的。本方法无须在河道中兴建构筑物,也无须清疏河道底泥,普遍适用于截污、清淤的河涌,以及受潮汐影响流态变化复杂的河道进行原位治理,恢复水体正常生态功能,为众多的城镇黑臭河涌提供了切实可行、经济方便的治理方法。Due to the urgency,complexity and the traditional method of treating the urban rivers in Guangzhou,this paper introduces an in-situ bioremediation technology on treatment of the black-odor urban rivers.Based on aeration,delivery of microbial agents,bioremediation of sediments and biological nest steps,this method can control and eliminate the pollution of urban rivers of exogenous, endogenous and sludge,and purify water,and improve the self-purification capacity of water bodies,and thus clean the urban rivers.Advantages,including no built-in structures needed in rivers,and no need to dredge the river sediment,are present.Generally,it is applicable to sewage interception and dredging of urban rivers,in-situ treatment of those rivers of complex flow patterns due to tidal effects,and thus to restore the normal ecological functions of urban rivers.Therefore,the proposed method provides practical and economic governance in many black-odor urban rivers.
