- 摘要:
- 为摸索出一套有用的重度污染源汇入湖泊管理手艺系统，立异性利用“污染源前处置+湖体水生态系统建立”分析手艺系统在项目实践，采取建筑早期雨水调蓄池、糊口污水截流进污水厂、污水厂尾水人工湿地提标、湖体建立水生态系统等办法对海口市某湖泊进行分析管理，并从化学和生物目标等方面进行周全评价。实践成果注解，前处置项目使外源污染负荷获得极年夜下降，可为后续生态修复缔造前提，直排污水经由过程污水厂处置后，氨氮和总磷浓度别离下降了63.55%和84.2%，尾水颠末人工湿地处置后氨氮浓度下降了59.5%，CODMn浓度下降了74.5%。水生态系统建立2个月后，水体清亮见底，首要水质目标较着优在管理前，3个月后水生态系统延续不变，水体消融氧浓度逐步上升，氨氮浓度延续降落，总磷浓度也有必然水平的下降，浮游动物生物量和品种显著增添，实现了污染湖泊管理的方针。另外，共同应急办法建立的水生态系统能在旱季必然雨污溢流后连结较不变状况，具有必然反抗外界干扰的能力。
- Abstract:
- Comprehensive technical system of “contamination source pretreatment and lake water ecosystem construction” was innovatively applied in engineering practice to explore a set of effective heavy polluted lake governance technology system. A series of comprehensive treatment measures such as construction of initial rainwater storage tank, sewage interception into wastewater treatment plant, treatment of tail water by constructed wetland and construction of water ecosystem were used in a lake in Haikou City, and the treatment effect was comprehensively evaluated from chemical and biological indicators. The pretreatment projects greatly reduced the external pollution load and created conditions for the subsequent ecological restoration. After the direct discharged wastewater was treated by the wastewater treatment plant, the concentration of NH3-N and TP was reduced by 63.55% and 84.2%, respectively. The concentration of NH3-N and CODMnin tail water decreased by 59.5% and 74.5% after treated by constructed wetland. After 2 months of water ecosystem construction, the water was clear, and the main water quality indicators were significantly better than those before treatment. After three months, the water ecosystem continued to be stable, DO gradually increased, NH3-N concentration continued to decrease, TP concentration also decreased to a certain extent, and the zooplankton biomass and species increased significantly, indicating that the lake governance goal was achieved. In addition, the water ecosystem built with emergency measures could maintain a relatively stable state after receiving a certain amount of rainwater and sewage overflow in wet season, and had a certain ability to resist external disturbances.
