| 摘 要： | 在水网密布、河涌众多的地区,存在着大量断头河道和盲肠河道,因无水源补给、水体长期滞留,大多呈富营养化状态,生态环境及景观功能丧失。以扬州市断头河富营养化水体净化为例,设计了人工曝气、生态净水砖和生物浮床等原位生物处理技术。工程效果显示：对COD的平均去除率为45%,去除范围35%～56%;对NH3-N的平均去除率为33%,去除范围17%～44%;对TN的平均去除率为28%,去除范围15%～39%;对TP的平均去除率为35%,去除范围25%～44%。说明原位生物处理技术对改善城市断头河富营养化水体水质效果显著。 |

Research on Application of In-situ Biological Technology on Water Quality Improvement in Urban Beheaded River |
|
| Abstract: | A lot of beheaded rivers or cecum riverways exist in water network and river concentration areas.Due to no water supply and stagnant water,eutrophication and function loss of the ecological environment and landscape have occurred in many rivers.The aim of the project was to solve water quality management problems in urban cecum rivers,by the application of in-situ biological treatment technology,such as artificial aeration,ecological water purification brick and material stuffing in biofilm treatment.It indicated that in-situ biological treatment had a significant effect on dealing with urban river eutrophication,and that water purification engineering operations were stable.The COD removal efficiency could reach 45% on average,ranging from 35% to 56%;the average NH3-N removal rate was 33%,ranging from 17% to 44%;the TN removal efficiency was 28% on average,ranging from 15% to 39%;the removal rate of TP was 35% on average,ranging from 25% to 44%. |
