摘 要: | 以昆山市凌家浜河道作为原位生态修复的试验对象,综合运用水生植物修复技术、生物膜技术等,改善水质。结合水生动物,平衡水体内浮游生物种类结构和数量,促进降解和转移水体中有机物质,达到河道生态系统原位修复的目的。研究表明:在有部分外源污染的情况下,采用该技术修复河道,水质改善显著,水体透明度、COD、TP、TN、NHN、叶绿素a等主要水质指标达到或优于地表水质标准。

APPLICATION RESEARCHES ON IN-SITU ECOLOGICAL RESTORATION TECHNOLOGY IN POLLUTED URBAN RIVER |

Abstract: | Based on ecological restoration of Lingjiabang River in Kunshan as test objects,the river ecosystem in-situ
restoration was tested. In the test,integrated aquatic plant restoration technology and bioflim technology were used so as to
improve water quality. Degradation and transfer of organic matter in river waters were promoted by means of balancing plankton
species composition and quantity. The results showed that in the case of the river exogenous contamination,the quality of river
water had been improved significantly by using in-situ ecological restoration technology. The main water quality indexes such
as the water transparency,water chemical oxygen demand ( COD) ,total phosphorus( TP) ,total nitrogen( TN) ,ammonia
nitrogen ( NH+
4 -N) ,chlorophyll-a were reached or excelled to the standard of the landscape water quality. |
