珠江三角洲城市河涌水体污染沉箱式生物处理研究

Research on Technology of Caisson-set Biological Purification of the Pearl River Delta Urban Cannel

针对珠江三角洲城市河涌水力特性和污染特征,在分析现有河道直接净化技术优缺点和治理经验的基础上,以东莞市挂影洲污染内河涌为实验研究水体,提出了沉箱式生物处理技术,进行了处理效果实验研究。实验结果表明:沉箱式生物处理技术具有去除COD和NH3-N的效果好、投资省、占地少和易于管理等优点。

Aiming at the hydraulic characteristics and pollution characteristics of the Pearl River delta urban cannel, take the Guaying continent in the city of Dongguang inland cannel pollution as experimental investigation waters, based on the analysis of advantages and disadvantages of the present direct purification technology and governing experience, we propose the caisson set biological processing and carried through the experimental investigation on processing effect. The experimental results demonstrate that caisson set processing have many advantages such as high treatment effeciency, low investment cost, fewer occupation of land and convenient management.
