| 中文摘要: |
| 以某城市为例，研究城市建筑泥浆的污染现状，并分析泥浆受到污染的原因。结果表明：对照《地表水环境质量标准》（GB 3838—2002）中的Ⅳ类标准限值，调研的4个工地泥浆水全部超标；该城市地层土壤中的有机质、总氮、总磷含量高是泥浆水超标的重要原因，工地制浆使用的地表水和污水也不能满足Ⅳ类水质的要求。在建筑工地的管理中，应限制现场使用污水和超标的河水来调制泥浆，同时加强场地管理，防止雨水和污水进入泥浆池，以便建筑泥浆的后续处理。 |
| 英文摘要: |
| Taking a city as an example, the pollution status of urban construction mud was studied, the causes of mud pollution were analyzed. The results showed that the muddy water from four construction sites investigated in the city all exceeded the standard limit of class Ⅳ water quality in " Environmental Quality Standard for Surface Water " (GB 3838—2002). The high content of organic matter, total nitrogen and total phosphorus in the urban stratum soil was an important reason for the excessive muddy water. The surface water and sewage used for mud making could not meet the requirements of class Ⅳ water quality. In the management of construction site, the use of sewage and excessive river water should be limited in mud making. At the same time, site management should be strengthened to prevent rainwater and sewage from entering mud ponds for subsequent treatment of construction mud. |
