Description
Technical field
The utility model relates to a kind of sewage disposal systems, more particularly, to a kind of zero-emission system of suitable industrial circulating water
System.
Background technique
Mankind's daily life be unable to do without water, and industrial production similarly be unable to do without water.Water consumption is also got over the development of industry
Come bigger, China is water resource critical shortage and the country that is unevenly distributed, and the effective use of water resource directly affects social economy
Development, therefore rationally and water conservation have become a critical issue.
Industrial water mainly includes boiler feed water, Municipal Sewage for Circulating, process water, water for cleaning etc..It wherein recycles cold
But water is to use water sport, and in industries such as petrochemical industry, steel, metallurgy, recirculated cooling water accounts for the 50%-90% of enterprise water use, special
It is not that 90 or more percent is accounted for as the Municipal Sewage for Circulating in thermal power plant.Since recirculating cooling water system is in continuous work mistake
A large amount of evaporations, free-and-easy etc. occur for Cheng Zhonghui, it is necessary to constantly to circulatory system moisturizing, so as to cause objects various in circulation
Matter is continuously increased concentration, wherein just including fouling tendency and corrosive ion calcium ion, magnesium ion, sulfate ion, carbonate
Ion, chloride ion, iron ion etc., these ions reach a certain concentration will the fouling in equipment and pipeline, while can corrode and set
Standby and pipeline.According to national standards, when the total content of chloride ion in recirculated water and sulfate ion is greater than 1100mg/1, circulation
System needs to carry out sewage treatment, and water amount of blowdown is big and belongs to industrial wastewater, need to handle it is up to standard after could discharge.
In line with water conservation and high-efficient water use principle, the generation of fouling and corrosion is all prevented with adding method thereof at this stage,
To improve cycles of concentration.The cycles of concentration of recirculated water be the recirculated cooling water salt content with its supplement water salt content it
Than.Cycles of concentration is improved, the dosage that can reduce supplement water can also reduce blowdown flow rate to save water resource, to reduce
Harm of the treating capacity and reduction of sewage to bad border.But the various medicaments being added are in the cost for increasing operation while having brought into new
Pollution factor, such as ammonia nitrogen, phosphorus etc..
The processing of circulating sewage at this stage is generally Alternative combination, including chemical precipitation tenderizer, filtration method, film point
From method, bioanalysis etc..After circulating sewage enters precipitation unit, flocculant etc. need to be added to precipitation unit and carry out coagulating sedimentation,
Most turbidity and suspended matter are removed, the sludge of precipitating can send processing outside.Large-scale recirculating cooling water system is generally used with stone
Sand or anthracite are filter tank by the gravity valveless of filtrate, and filtering velocity can only be controlled in 10m/h hereinafter, and the suspended matter of cooling water
Concentration can only be controlled in 10mg/L hereinafter, the increase of blowdown flow rate causes infrastructure investment to increase.The water outlet of precipitation unit enters filtering
Unit, generally successively into PCF filter, self-cleaning filter and ultrafilter excessively, the same Treatment of Sludge of filter residue.Filtrate due to
There is the presence of ammonia nitrogen and phosphorus etc., need to just can enter reverse osmosis Deng desalinations unit after biochemical treatment.Hyperfiltration can be effective
The harmful components such as hardness, microorganism in cooling water are removed, there is a higher salt rejection rate, the water rate of recovery can achieve 75%~
90%, the disadvantage is that requiring harshness to influent quality, and the pressure oscillation in operational process easily leads to film and is destroyed, the corrosion in water
Product and microorganism easily block pre-flock device and reverse osmosis membrane, pollution, and frequent cleaning increases operating cost and disposable
Input cost is higher.Desalination unit desalination water can directly return to circulation, and concentrated water can enter evaporation element and handle.
As shown in Figure 1, the treatment process of conventional recycle sewerage are as follows: circulation needs to add scale inhibition into recirculated water
Agent, fungicide and corrosion inhibiter.System sewerage in circulation is introduced into precipitation unit 11 and flocculant is added except big
Partial turbidity and suspended matter, the sludge of precipitating send processing outside.The clear liquid that precipitation unit 11 exports enters filter element 12, filters
Filter residue also sends processing outside afterwards.The filtrate that filter element 12 exports enters biochemical unit 13 for removing ammonia nitrogen and phosphonium ion.It is biochemical
The treatment fluid that unit 13 exports enters desalination unit 14, and the desalination water that desalination unit 14 generates returns in circulation again
Secondary utilization, the concentrated water that desalination unit 14 generates can enter evaporation element and handle.
