城市黑臭水体底泥处理技术的比选研究

Comparison and Selection of Sediment Treatment Technology for Urban Black and Odorous Water

城市黑臭水体底泥的治理是水污染防治的重要环节。笔者在广泛调研国内外底泥处理技术现状的基础上,从底泥中重金属的去除、底泥脱水、余水处理3个方面,研究了黑臭水体底泥处理可采用的技术方案,探讨了各类处理技术的优缺点,提出了选择最佳处理方案需要综合考虑的影响因素。

The sediment treatment of urban black and odorous water is an important part of water pollution prevention and control.On the basis of extensive research on the current status of sediment treatment technology at home and abroad,the author has studied the technical solutions available for the sediment treatment of black and odorous water from three aspects:removal of heavy metals in the sediment,dewatering of the sediment,and treatment of residual water.The advantages and disadvantages of various treatment technologies are discussed,and the influencing factors that need to be considered comprehensively in selecting the best treatment scheme are proposed.
