鱼塘溪水环境容量提升方案分析

Analysis of the Scheme for Improving the Water Environmental Capacity of Yutang Creek

通过对鱼塘溪水环境容量进行计算,发现明溪经济开发区污水处理厂扩建后鱼塘溪流域COD容量为254.46 t/a,氨氮容量为10.10 t/a,总磷容量较小,仅剩0.2/a,后期对鱼塘溪生态补水方案进行预测分析,保证在经济发展的基础上实现鱼塘溪水环境容量安全。

This article calculates the water environmental capacity of Yutang Creek and finds that after the expansion of the sewage treatment plant in Mingxi Economic Development Zone,the COD capacity of the Yutang Creek basin is 254.46t/a,the ammonia nitrogen capacity is 10.10t/a,and the total phosphorus capacity is relatively small,with only 0.2/a left.In the later stage,the ecological water replenishment plan of Yutang Creek is predicted and analyzed to ensure the safety of the water environmental capacity of Yutang Creek on the basis of economic development.
