查询词典 pollutants

On the base of reviewing the development of NSP models, some deficiencies of existent models are analysed and listed as follows: most models can be applied only to very small watershed; mechanism models involve too many parameters which can not be calibrated properly by limited data; amoung practical models, empirical models are much more common than mechanism models; most models are focus on the conservative soluble pollutants rather than non-conservative and particulate pollutants; almost all models rely highly on the measured data, and there are fewer studies about the load estimation for ungauged areas.

本文在评述非点源污染模型研究进展的基础上，分析了现有模型的不足，主要有：大多数模型只能适应于很小的流域面积；机理类模型参数过多，率定困难，应用效果不理想；实用模型中，经验类模型多，机理类模型少；对保守性的液态污染物研究得较多，对非保守性和固态污染物研究得较少；各类模型均高度依赖于实测资料，无资料地区的模型或预测方法研究得很少。

These porblems are: legislation on city plan is deficient, causing unavoidable water pollution under many circumstances; there is lack of effective control of the two major pollutants:industrial sewage and daily sewage; the construction of relative organs is unable to meet the need of environmental protection; the underground water isnt under complete protection;control on other pollutants is unsufficient;local legislation is banal.

具体表现为环评制度、清洁生产制度等存在弊端，无法真正实现对工业废水的源头控制；对生活污水的立法仅限于末端治理，有关节约用水的立法空白较多；现有的城市污水处理系统由于缺乏法律的保障，从设置到运转状况均不能令人乐观；③城市水污染监管体制亦存在漏洞；④对地下水保护不力；⑤对其他污染源控制漏洞较多；⑥地方立法缺乏特色。

Some pollutants with deadly toxicity and complex form, such as HC1, heavy metals and dioxins were very harmful to peopel health and environment.
