生态塘系统在小微水体处理实践中的应用

Application of Ecological Pond Systems in Small and Micro Water Treatment Practice

由于生态塘系统是一种投资低,处理效果好的生态处理系统。采用生态塘系统处理小微水体投资小,可快速改善水质,底泥处理采用原位处理方式,通过投加底改药剂和底改菌剂的实施治理,可以解决内源污染-即底泥中的污染物进行固化不再释放进入水体中,最终使得水体消除黑臭,并通过生态修复工程,提升水体周边景观环境。对南方某镇生态修复工程使用生态塘系统后COD除率81.9%;氨氮降去除率为82.6%;总磷除率达90.5%;工程完工后水质明显改善,水质从劣Ⅴ类变为Ⅴ类,黑臭消除。

Ecological pond system is an ecological treatment system with low investment and good treatment effect.The use of ecological pond system to treat small and micro water bodies has small investment which quickly improve the water quality.The in-situ treatment method is adopted for sediment treatment.Through the implementation of treatment by adding bottom modification agent and bottom modification bacterial agent,the endogenous pollution can be solved.That is,the pollutants in the sediment can be solidified and will not be released into the water body,which will eventually eliminate the black odor in the water body,and improve the surrounding landscape environment of the water body through the ecological restoration project.After the ecological restoration project of a town in the south uses the ecological pond system,the COD removal rate is 81.9%;the removal rate was 82.6%;the total phosphorus removal rate was 90.5%;after the completion of the project,the water quality was significantly improved.The water quality changed from inferior V to V,and black odor was eliminated.
