摘要
针对佛山亚艺湖水质恶化带来的生态退化及异味等问题,采取了控源截污、内源污染治理、水生态修复、混凝微滤净化和生态补水等工程措施。运行期间,面对外来鱼类入侵、藻华暴发、强降雨调蓄问题,采取了有针对性的防控措施。经过多元化综合治理,亚艺湖水质从地表水Ⅴ类标准提升至Ⅲ类标准,其中,COD<14 mg/L;DO平均值>6.22 mg/L,是治理前的2倍;氨氮<0.12 mg/L,氨氮去除率≥95%;TP<0.08 mg/L。可见,亚艺湖生态系统已恢复正常,水质处于稳定向好状态。
Aiming at the ecological degradation and odor resulting from water quality deterioration of Yayi Lake in Foshan,a range of engineering measures,such as pollution source control and sewage interception,endogenous pollution control,water ecological restoration,coagulation micro-filter purification,and ecological water replenishment,have been implemented.In response to challenges such as alien fish species invasion,algal bloom outbreaks,as well as regulation and storage of heavy rainfall during operation,specific prevention and control measures have been undertaken.Through diversified and comprehensive treatment approaches,the water quality of Yayi Lake has significantly improved from level Ⅴ to level Ⅲ in Environmental Quality Standard for Surface Water(GB 3838-2002).Notably,the concentration of COD is now below 14 mg/L;the average DO exceeds 6.22 mg/L,twice as much as before treatment;ammonia nitrogen are below 0.12 mg/L with removal rate no less than 95%;TP concentration is below 0.08 mg/L.As a result of these efforts,the ecological system of Yayi Lake has been restored to its normal state with stable and good water quality.
