Description
Technical field
The invention belongs to the river pollution degree in environmental protection to monitor art field, be specifically related to a kind of monitoring fully-loaded stream
The method of contaminated degree.
Background technique
Increasingly with the continuous development of industrialization and people's living standard, either industrial waste or sanitary waste
It is more, and significant portion therein is directly discharged in river without environmentally friendlyization processing, thus leads to the dirt in river
Dye.
In order to monitor the contaminated degree in river, data supporting is provided for the prevention and treatment of river pollution, often in the prior art
Using following technical scheme：
Chinese patent application 201110046575.3 discloses a kind of method of diagnosing river pollution in real time comprising：River
Flow pollution diagnosis platform, pollution level evaluation module, pollution cause diagnostic module, blowdown scheme optimization module, computation model pipe
Manage module and database management module；When completing a pollution diagnosis engineering, this method executes according to the following steps：A. start river
Flow pollution diagnosis platform；B., basic parameter is set；C. river pollution scale evaluation is carried out；D. river pollution cause diagnosis is carried out；
E. contaminating enterprises' blowdown scheme optimization is carried out；F. result output is carried out.Realize the method equipment include：Flowmeter, GPS core
Piece, solubility detector, singlechip group at remote terminal.The technical solution realizes the reality of river pollution degree and pollution cause
When diagnose, input water correction target or pollution level reduce target after also produce the optimization side of contaminating enterprises' blowdown along the river
Case is good for the environment department's real-time monitoring river pollution situation, carries out Discussion On Measures of Rivers Pollution Treatment to the ill, and science carries out emission reduction planning.
But the technical solution uses numerous modules, structure is complicated, and different modules has the risk of data distortion,
It is easy to cause the inaccuracy to the monitoring of river pollution degree.
Chinese patent application 201710664120.5 is disclosed a kind of observed based on water quality of river and calculates that upstream enters river pollution
The method of flux, key step include 1) Outlet Section water quality process observation data collection；2) River Water Quality Process computation model
Building；3) River Water Quality Process associated model constructs；4) enter river pollution flux optimization to calculate.This method uses lower reaches of river section
Water concentration process observation data realize the high-precision estimation into river pollution flux, avoid using root in conventional method
It estimates according to Land use data into the uncertain excessive problem of river pollution flux.
But the method that above-mentioned observation calculates that upstream enters river pollution flux is using the method calculated, during reckoning
It needs by a large amount of intermediate computations；It is well known that the intermediate data being related in calculating process is more, result data deviation is got over
Greatly, thus lead to final result data inaccuracy, be difficult really to react the contaminated situation in river.
On the other hand, since current China's vegetation deterioration is serious, there are more fully-loaded stream, the river water of fully-loaded stream
It due to the difference of depth, is influenced by buoyancy, gravity or flowing, the substance contained in water body is different, and water body is caused to be layered, and produces
Raw multiple water layers；It is above-mentioned in the prior art to the contaminated degree in river when monitoring the contaminated degree of fully-loaded stream
Technical solution cannot exclude the influence of silt and water body layering in fully-loaded stream, thus can not accurately monitor contaminated
The case where water body in river contaminated degree.
Had shown that through a large amount of research of applicant, by COD can monitor fully-loaded stream it is contaminated
Degree.
COD is chemically to measure to consume the suitable of oxygen when organic matter is aoxidized by strong oxidizer in water sample
Amount, to indicate the number of Organic substance in water amount.Water sample under certain condition, with reproducibility object in the water sample of oxidizing units volume
The amount of oxidant consumed by matter be index, be converted to per unit volume water sample be all oxidized after, the milligram of the oxygen needed
Number, is indicated with mg/L, to reflect the degree polluted in water by reducing substances.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for monitoring the contaminated degree of fully-loaded stream, to solve above-mentioned background
