资源简介:
总磷是水样经过消解后将各种形态磷转变成正磷酸盐后测定的结果。检测水中总磷的含量其目的就是为了不伤害的生态环境和人体健康问题,可以对水质中总磷含量的情况进行安全性评价,为政府监管、居民生活以及生态环境提供参考和技术支撑。通过对某一河道采样点位采样的水质总磷的检测,依据水质总磷的测定钼酸铵分光光度法GB/T11893- 1989,取样采集到的水质体积V(mL),由校准曲线查得的磷量M(μg),根据样品确认稀释倍数D,得出水质中总磷的数值,公式如下:总磷C(mg/L)=(M/V)*D。通过国家分类标准GB 3838-2002表得出最后的结论判断,水中总磷检测的结论分为4类,III是三类水,含量≤0.2mg/L,IV是四类水,含量0.2-0.3mg/L,V是五类水,含量0.3-0.4mg/L,超过V的标准值(>0.4mg/L)就是劣五类水则是不合格,影响人体健康及环境生态,需要相关监管部门监管并治理。本数据可以对水质中总磷含量的情况进行安全性评价,为监管部门靶向监管、污水处理、居民生活提供技术支撑。

Total Phosphorus (TP) refers to the measured value obtained after digesting a water sample to convert all phosphorus species into orthophosphate. The primary purpose of detecting total phosphorus in water is to prevent harm to the ecological environment and human health, conduct safety assessment of total phosphorus content in water quality, and provide reference and technical support for government supervision, residents' daily life and ecological environment protection. For the detection of total phosphorus in water samples collected from a sampling site of a specific river, the total phosphorus concentration is calculated using the following formula in accordance with the national standard method for the determination of total phosphorus in water quality: Ammonium Molybdate Spectrophotometry GB/T 11893-1989. The formula is derived based on the collected water volume V (mL), the phosphorus mass M (μg) obtained from the calibration curve, and the confirmed dilution factor D of the sample: Total phosphorus concentration C (mg/L) = (M/V) * D. The final classification result is determined according to the table in the National Environmental Quality Standard for Surface Water GB 3838-2002. The detection results are divided into four categories: Class III water (total phosphorus concentration ≤0.2 mg/L), Class IV water (0.2 mg/L < C ≤0.3 mg/L), Class V water (0.3 mg/L < C ≤0.4 mg/L), and inferior Class V water (C >0.4 mg/L), which is unqualified and poses risks to human health and ecological environment, requiring supervision and remediation by relevant regulatory authorities. This dataset can be used to conduct safety assessment of total phosphorus content in water quality, providing technical support for targeted supervision by regulatory departments, sewage treatment and residents' daily life.
