龙岩市新罗区污水处理厂的环境效益研究

详细分析了龙岩市新罗区污水处理厂2001年-2005年间的投入和运行成本,在此基础上结合龙岩市新罗区污染物排放量的削减情况对该污水处理厂的环境效益进行分析。本文着重研究了该厂由于COD、氨氮和总磷减排所产生的环境效益,分析了COD、氨氮和总磷的削减情况,结合总投资计算了它们的效益-投入比并比较它们环境效益的大小。将COD、氨氮和总磷减排量所产生的环境经济效益分别相加,就可以得到2001年-2005年期间龙岩市新罗区污水处理厂所获得的环境效益值;结合各年度的投入成本值,则可以得到该污水处理厂分年度的效益-投入比。最后,本文对九龙江流域污水处理厂的环境效益做了预测。

Environmental Benefit Research of Longyan Wastewater Treatment Plant

This article analyzed the investment and the running cost of Longyan City Wastewater Treatment Plant between 2001 and 2005, and on this basis we analyzed this plant＇s environmental benefit combining with the reduce situation of pollutants discharge amount of Longyan City Xinluo District. We focused on this wastewater treatment plant＇s environmental benefit due to the reduction of COD, ammonia nitrogen and total phosphorus, and analyze their reduce situation, and compared their environmental benefit com- bining the investment. Then, we add the environmental benefit of discharge reduction of COD, ammonia nitrogen and total phos- phorus and we could get the environmental benefit of Longyan Xinluo District Wastewater Treatment Plant during 2001 and 2005. Furthermore, we could get the annual ratio of benefil to investment of this wastewater treatment plant combining with annual invest- ment. At last, we predicted the environmental benefit of wastewater treatment plants of Jiulong River Catchments.
