摘要
北海市红坎污水厂提标改造工程处理规模20万m3/d,通过对现状二级出水水质指标分析,确定深度处理工艺进水水质及主要去除指标,深度处理采用BAF后置反硝化生物滤池技术+LHPS高效斜管沉淀池工艺。对深度处理核心工艺及加药部分工程设计进行了具体介绍,并对外加碳源选择进行分析,相关经验可供类似工程参考。
The treatment scale of Beihai Hongkan Wastewater Treatment Plant Upgrading Reconstruction Project is 200 000 m3/d. Through the analysis of the current secondary effluent quality index, the influent quality and main removal index of the advanced treatment process are determined. The BAF post-denitrification biofilter technology and LHPS high efficiency inclined-tube settling tank process are adopted for the advanced treatment. The engineering design of core technology and dosing part of the advanced treatment is introduced in detail, and the selection of external carbon source is analyzed. The relevant experience can be used as reference for the similar projects.
