Description
Technical field
The present invention relates to water environment ecological techniques, more particularly to a kind of to obtain region based on water environment benchmark and cost analysis
The method and device of water standard limit value.
Background technology
Water is the resource that each species are depended on for existence on the earth.As the size of population is on the increase, per capita water resource owning amount
Increasingly reduce, meanwhile, the fast development of modern times industrial or agricultural economy, water environment is faced with seriously threatening for various pollutions, example
Such as, the excessive agriculture chemical pollution of sanitary sewage, factory's chemistry medicine pollution, blowdown waste discharge and using in farmland.That is,
While per capita water resource owning amount is increasingly reduced, water quality and functional water shortage caused by water environment degradation are also
It becomes increasingly conspicuous, it has also become outstanding, global common technical problem.
Currently, China's water environment pollution is mainly reflected in:Pollutant discharge amount is more than Water Environment Carrying Capacity, urban river water dirt
Dye, the black smelly, lake eutrophication in river.Water environment pollution causes ecological disruption serious, and bio-diversity is reduced, ecosystem work(
It can degenerate, to restrict socio-economic development, endanger people's health.
In order to control water pollution, protection and improvement quality of water environment, the water environment for different regions is needed, is formulated related
Region water quality standard limited value, to as the distinguishing rule for whether water quality in water environment occurring water pollution, and be follow-up water
The update of matter standard provides reference and foundation.Wherein, water standard (WQS, Water Quality Standards) is to judge water
The key technical index of environmental quality is indicated with believable science data for the purpose of protecting human health and the ecological balance
Water environment in various pollutants safe level.And the region water quality mark that water pollution whether occurs for assessing water quality obtained
Quasi- limit value, and be the scientific basis for updating water standard.Thus, how reasonably to obtain for assessing whether water quality occurs water dirt
The region water quality standard limited value of dye protects aqueous bio diversity for controlling the type and quantity into water environment pollution object
And the structure and function of entire aquatic ecosystem is of great significance.
In the prior art, developed country is generally by formulating unified national water environment benchmark, for example, the U.S. is by U.S.'s ring
The national water quality mark of guarantor office (USEPA, The United States Environmental Protection Agency) publication
National water standard is revised according to Honshu Regional Water Environment situation in standard, each state, works out the state water quality mark for adapting to Honshu
Standard, meanwhile, each state obtains water effect ratio (WER, the Water of the section for the water quality difference of different sections in different zones
Effect Ratio), using the national water environment benchmark of formulation and water effect than product as the area of the section region
Domain water standard limit value.Wherein, it is to configure water and region original in laboratory respectively using same species in obtaining WER methods
Parallel toxicity test is carried out in water, obtains the species to same toxic endpoints (such as half lethal concentration LC50) region raw water toxicity
Water poisonous effect value is prepared in effect value and laboratory, and zoning raw water poisonous effect value prepares water poisonous effect with laboratory
The ratio of value, obtains WER values, the region water quality standard limited values of different zones be equal to national water environment benchmark be multiplied by the region into
The WER values that the parallel toxicity test of row obtains characterize the water quality inferiority in each region so as to be based on region water quality standard limited value
It is different.
But the existing method for obtaining region water quality standard limited value, since America's economy is highly developed, and long-term concern is certainly
Right environmental protection so that water pollutant load is lighter at this stage, thus, in formulation (acquisition) region water quality standard limited value,
Whether American National or u s. state, more attention are the protections to natural environment, are not considered to economic development
It influences.
The water standard limit value for the tens of pollutants that European Union issues at this stage, adheres to the formulation of water standard limit value
Theory and technical method and the U.S. it is almost the same, be also entirely to pay the utmost attention to protection to water environment, do not consider to send out economy
The influence of exhibition.
The region water quality standard limited value in China is issued by unification of the motherland, and the formulation or acquisition of region water quality standard limited value are main
With reference to the water environment benchmark and WER values of external advanced country.But China is vast in territory, and no matter the water environments of different zones is from water
Matter feature, Biogeographic Characteristics, Regional Water Environment characteristic still from the structure feature of the ecosystem, all have with foreign countries obviously
Difference, and China is developing country, and water environment combined pollution is serious.Therefore, according to the external water environment benchmark announced with
And WER values obtain the region water quality standard limited value in China, the region water quality standard limited value accuracy of acquisition is not high, cannot be region
Water environment management provides effective technical support, and the biology effectively for China difference waters provides comprehensive protection, it is difficult to meet
China's water environment management simultaneously realizes the long term object that Water-environment Ecological System develops in a healthy way;Further, since China's water environment pollution
It is more serious, if controlled water quality according to external more harsh region water quality standard limited value, each enterprise is needed to spend
Huge treatment cost influences economic development to bring difficulty to the normal production and operation of enterprise;Moreover, because water environment
Pollution control is of high cost, leads to that the regulation for executing region water quality standard limited value is unwilling or evaded compared with multiple enterprises, so that water
Environmental pollution improvement's implementation capacity is weaker, and Water Environmental Pollution Control effect is undesirable.
Thus, at present formulate or obtain region water quality standard limited value, do not account for China's Regional Water Environment characteristic with
The protection of Biogeographic Characteristics etc. does not account for more protecting without the technical method of specifically formulation region water standard yet
It is also required to consider economic development and enterprise development while environment so that economic development, enterprise development and water environment pollution
Improvement cannot take into account simultaneously, and Water Environmental Pollution Control is of high cost, poor so as to cause Water Environmental Pollution Control effect.
