Description
Technical field
The present invention relates to water resource environmental technology field, more particularly to a kind of industrial fresh water collocation method and system.
Background technology
Steel and iron industry is water consumption and blowdown rich and influential family in industrial circle, and its water consumption accounts for the 14% of national industry water consume, discharge
Sewage quantity accounts for the 12% of industrial total discharge.《The 12nd five-year-plan outline of national economy and social development》Regulation is " ten
Two or five " during, unit industrial added value water consumption needs reduction by 30%.Ministry of Water Resources represents that " it is right to be possible to from now on a few days ago simultaneously
Key area carries out water total amount control with water rich and influential family.After target water is using finishing, newly-increased water can only be by water right definition
Meet with using non-traditional water source ".
Liaoning Department of Water Resources of Shanxi Province holds press conferences on April 21st, 2011 simultaneously, announces《Forbid extracting underground water in Liaoning Province
Regulation》Implemented from 1 day April in 2011, the whole province forbids various regions extracting underground water, and existing underground water water intake engineering should
When time limit closing.The industrial water of iron and steel enterprise is higher to the degree of dependence of underground water, extract underground water ban implementation for
Production will produce tremendous influence.Therefore, in order to maintain enterprise's normally production activity, carry out industrial fresh water compositional optimization and grind
Study carefully and be just particularly important.
Paper in terms of industrial water resource energy-conserving and environment-protective is such as：1. Tang Pei Fujian, Wang Xue east integrated iron and steel works water tandem
Use pattern research [J] mining industry bulletins, 2006 (10)：44-46. articles point out, iron and steel enterprise's production Technology entirety
Fall behind, technology of waste water control is low, and the utilization rate of water is low, has resulted in serious waste and the pollution of water resource.Although many large-scale
Cycling use of water measure, i.e. waste water has been taken to be back to original production operation after treatment in iron and steel enterprise, but its water use efficiency is still
It is not high.On this question, it is proposed that integrated iron and steel works' water tandem uses new model.Water cascade use mode refers to, upstream water
The waste water (water quality meets downstream production requirement) of the discharge of water process uses water without what treatment can be supplied to downstream water demand operation
Pattern.In iron and steel enterprise, each technique, the water quantity and quality requirement otherness of production process are big, and this otherness is convenient to carry out
Water cascade use mode.Water cascade use mode alleviates the contradiction of supply and demand for the water resource, improves the total amount usable of water resource, but do not have
Have and inherently industrial fresh water water source is optimized.
2.Piet Lens, Look Hulshoff Pol, Peter Wilderer, Takashi Asano. translate into Xuzhou etc.
Industrial water circulation and resource reclaim [M] China Construction Industry Press, 2007.Lens et al. are returned after proposing sewage proper treatment
With that is, degree for the treatment of depends on the water quality requirement of specific reuse purposes and correlation.Also the money such as relevant water is mentioned in ecosystem industry
The gradient in source is used, i.e., the low water supply by stage of high-quality use high, low-quality.Its common thought is exactly：Recycle-water can be according to difference
Reuse purpose and implement Multiple Cycle water standard, " because of family water ", reduce cost for wastewater treatment.Industrial Water circulation into
This efficiency depend on a series of industrial correlative factors, such as needed for water water and water quality, water resource and industrial user between away from
From.Article do not refer to and optimization provided in terms of resource of water supply, emphasis be intermediate link reuse.
3. Cai builds peace, Peng Yongli, Bao Sheng, etc..The answering in Metallurgical Waste Water resource based on water quality energy level and GIS new algorithms
With [C] China Environmental Sciences association's Annual Conference collection of thesis (2009).Beijing：Publishing house of BJ University of Aeronautics ＆ Astronautics, 2009:
563-569. Cai builds peace etc. and proposes water quality energy level concept, and tentative calculation is carried out in Metallurgical Waste Water resource, water supply by stage,
Waste water recycling is processed with water process cost minimization, realizes that waste water " zero " is discharged.
The use regimen condition of domestic each iron and steel enterprise is totally different, and based on purifying river water, Tang Gang is then Baosteel with municipal middle water reuse
