Description
Technical field
The invention belongs to field of environment protection, and in particular to one kind is watered row for environmental management department online monitoring and management enterprise
The system and method for dirty behavior.
Background technique
During the speed-raising of China's process of industrialization, the limitation of industrial foundation and production technology level so that high pollution with
Pollutant reduction process rate becomes this stage typical case's contamination characteristics, and thus bring water pollution problems is got worse.According to 2015
China Environmental State Bulletin shows, the river in China, river, lake, in reservoir, contaminated to account for about 82.3%, there is monitoring in the whole nation
In 1200 rivers of system, 70.8% by different degrees of pollution, national IV~V class water of fresh water environment and bad V class water
Matter water body occupies very big ratio, wherein IV~V accounts for nearly 30%, and bad V class water body accounts for nearly 10%.Thus caused water quality
Water shortage problem is got worse, and water imbalance between supply and demand is continuously increased, it has also become it is benign in new historical stage social economy to restrict China
The bottleneck of development.
Industrial wastewater has the characteristics that type is more, it is complicated to administer, concentration is high, flow is big.According to Chinese Ministry of Environmental Protection's environment in 2015
Count annual report, discharged volume of industrial waste water be 205.3 hundred million tons, wherein highest three industries of discharge amount be chemical industry, papermaking and electric power,
It is largely organic matter that an outstanding feature, which is its pollutant, in these industry waste water, and bioanalysis is that removal organic polluter is most normal
Method.The water outlet of industrial wastewater often flows directly into channel, rivers, lake, it is also possible to permeate the ground, soil, therefore, not
Handle or handle incomplete industrial wastewater can not only polluted surface water, underground water and soil, can also be reached by food chain
In human body, do harm to huamn body.Therefore, it is necessary to which the discharge of Working at Industry Waste Water, reduces the harm of industrial wastewater bring.
To ensure that water quality and water safety, China have put into effect a series of statutes and regulations.In April, 2015, state affairs
Institute has formally issued " water prevention and cure of pollution action plan ", and referred to as " ten, water ", one of them is exactly comprehensive control pollutant emission.
Ended for the end of the year 2012, the whole nation is completed 344 provincial, prefecture-level monitoring centers, is mounted with automatically 15559 major polluting sources
Environment ability to supervise is greatly improved in monitoring device, has automation, the information-based environment supervision of China's characteristic to construction
System has stepped essential step, and the situation of " waste water is by seeing ", which has, significantly takes on a new look, although online automatic monitor
Achieve the effect that whether real-time monitoring water outlet water quality is up to standard, cannot but prevent enterprise from handling sewage by way of being watered,
And this kind of event is much, enterprise is often in order to save sewage treatment process transformation and running cost, frequently with clear water or cold
Ningxia ADC foaming agent was just reported in discharge after condensate dilution keeps Pollutants in Wastewater concentration up to standard, Focus early in 07 year
Manufacturing enterprise reaches discharge standard by being watered diluted mode, and Nanjing " environmental pollution crime " First Case is also by being watered dilution
Method send to sewage treatment plant handle, although dilution can achieve requirement of the environmental management department for water outlet, not
The total amount of pollutant can be reduced, the pollutant being discharged into river can also threaten safely to water body.Simultaneously, it is contemplated that environmental management
The problem of department law enfrocement official deficiency invents a kind of system that online monitoring and management enterprise is watered blowdown behavior and is of great significance.This
A kind of system for being watered blowdown behavior for environmental management department online monitoring and management enterprise of disclosure of the invention, including it is located at biochemical treatment

Terminal system (3) at department, the present invention, which goes back while providing, is watered blowdown behavior using above system online monitoring and management enterprise
Method, comprising the following steps: sample detecting system I (1) and sample detecting system II (2) are responsible for biochemical processing process advancing water
With the measurement of sewage draining exit water sampling, pretreatment and BOD and COD, measurement result is transmitted to terminal system by wireless technology
(3), terminal system (3) judge that enterprise whether there is and is watered blowdown behavior to receiving after data mart modeling calculates, and will test result
Real-time display is, it can be achieved that on-line monitoring enterprise is watered the behavior of blowdown.
