Description
Technical field
The present invention relates to environmental science and monitoring technical field, it is related to a kind of quality evaluation method, is then specifically development one
Plant and be based on by ammoniacal nitrogen (NH4- N), permanganate index (CODMn), nitrate (NO3- N), dissolved oxygen (DO) and turbidity
(tur) WQI of compositionminCarry out the method for water quality of river Fast Evaluation and water quality category division.
Background technology
Because natural process, mankind's activity and water resource are using reasons such as increases, deteriorating water quality turns into the world today
The most important environmental pollution problem faced, causes the extensive concern of domestic and international scientist and administrative department.It is worth noting that,
Following freshwater resources can be more rare, so as to jeopardize utilization of the mankind to water resource, particularly its drinking water function and its
Important function in economic development.The World Health Organization finds that the drinking water of global about 1,100,000,000 populations can not obtain effective guarantee.
It can be seen that, the protection to Freshwater ecosystems water resource is particularly important, and numerous countries and regions are carried out in this aspect
Extensive work.River ecosystem plays an important role in terms of human health and economic development, simultaneously as taking
The waste water such as band life and industry, its water quality is highly prone to pollution.
Water quality assessment is particularly important to contamination control and resource management.On the one hand, by water quality assessment, we can be with
Fresh water water resource water quality condition and its variation tendency are grasped, scientific basis is provided for water resources management.On the other hand, water quality is carried out
Appraisal, contributes to major pollutants and its contribution to water quality change in time and space in identification water body, so that what manager had
Arrow is put, water resource is preferably managed.In addition, the acquisition based on water quality condition, the public can more energetically participate in environment
Work is protected, is conducive to the smooth implementation of environmental practice.
Therefore, efficiently and quickly evaluating water quality situation be carry out water pollution preventing and treating and groundwater optimal management premise and
It is crucial.Domestic quality evaluation method conventional at present is single factor evaluation method, biological assessment method etc..Because evaluation result is depended on
Worst index, single factor evaluation method can not concentrated expression water quality situation.Biological assessment is wasted time and energy, and evaluation result compared with according to
Rely the identification level in analyst.At present, evaluation of river water quality is generally carried out using water quality index (WQI) in the world, it is integrated
Numerous environmental index, and a single numerical value is effectively translated into, to reflect water quality condition, solve each factor evaluation knot
The problem of fruit differs, is conducive to manager to carry out relevant Decision.But, this method needs to carry out the survey of a large amount of water quality parameters
It is fixed, it is with high costs, and a large amount of chemical reagent used in water quality parameter continuous mode also have harm to water environment.In order to enter one
Step promotes China's present status and trend monitoring and prevents and treats the research of theory, in the urgent need to a kind of accurate, simplicity of development, quickly, just
Preferably with the evaluation of river water quality method of of low pollution.
