“五色时空·水下森林氧吧”技术在城市湖泊生态修复的实践--以广东肇庆七星岩景区里湖生态修复为例

Application of 5SSK-UF·OB ecological technology in urban lakes--An example in Lihu Lake of Qixingyan

肇庆七星岩景区里湖受到各种外源污染和内源污染问题而污浊。“五色时空·水下森林氧吧”地表水生态修复技术(简称“5SSK-UF·OB”技术)修复地表水生态系统食物链,恢复七星岩景区里湖水生态系统自净功能,水环境质量保持在《地表水环境质量标准》(GB 3838—2002)Ⅲ类及以上水质标准,每天单位面积水草消耗营养物质量较大,定量污水进入里湖水生态系统后,水质仍能保持在地表水Ⅲ类标准及以上。

The Lihu lake of Qixingyan in Zhaoqing has had many problems about external pollution and endogenous pollution in many years.5SSK-UF•OB ecological technology repaired the food chain in aquatic ecosystem and restored the self-purification function.The water environmental quality in Lihu lake maintenance“surface water environmental quality standards”(GB 3838—2002)Ⅲwater quality standards and above,the amountment of nutrients consumed per unit area and per day is large,ensuring the long-term operation of the aquatic system,even if the sewage gets into the ecosystem.
