- 摘要:
- 对辽河流域重污染河流条子河进行了历史监测数据的调研和现场采样监测评价，结果表明:四平市污水处理厂运行前，条子河水质严重污染，COD浓度最高为250 mg·L-1，氨氮浓度最高为35.9 mg·L-1；四平市污水处理厂运行后，条子河水质有所改善；在丰水期COD指标满足《地表水环境质量标准》V类水质标准；而枯水期COD指标均低于《地表水环境质量标准》V类水质标准。不同水期氨氮指标均低于《地表水环境质量标准》V类水质标准。从不同断面的分析结果看出，在条子河上建设人工干预的河流净化工程，提高污水排放标准，是保证条子河水质达到《地表水环境质量标准》V类水质标准的有效方式。
- Abstract:
- The monitor and evaluate on Tiaozi River, one of the most polluted tributaries in Liaohe River Basin, were conducted by using the history monitor data and situation sampling. The results showed that the COD of Tiaozi River was 250 mg·L-1, NH3-N was 35.9 mg·L-1, before the Siping municipal wastewater treatment plant was build and the river was polluted seriously. After the Siping municipal wastewater treatment plant came into working, the water quality was improved obviously. COD of the surface water in Tiaozi River in high flow period didn’t exceed the class V standard of “Surface Water Environment Quality Standard” (GB3838-2002). COD of the surface water in Tiaozi River in low water season exceeded the class V standard of "Surface Water Environment Quality Standard" (GB3838-2002). NH3-N of the surface water in Tiaozi River exceeded the class V standard of “Surface Water Environment Quality Standard” (GB3838-2002) in all the months. The results also indicated that building the water disposal project, improving the discharge standard of pollutants, was the effective way to deal with the water pollution in Tiaozi River.
