Description
Technical field
The present invention relates to refinery method for treating desulfurized wastewater.
Background technology
Recirculated water can constantly evaporate during reciprocal use in cooling tower, cause the dissolved matter in cooling water
Constantly concentrated with solid particle.In open type circulating water cooling system, cooling water is converted into through supercooling after heat exchanger
Hot water, sprays downwards in cooling tower, and countercurrent mass transfer effect is formed with the air flowed up, thus is cooled down.Heat is handed over herein
During changing, air produces cooling water stripping effect, escapes the carbon dioxide in cooling water, causes the pH liters of cooling water
Height, increases the risk of fouling in the system.Cooling water after heating is outstanding in air can be eluted during spraying downwards
Floating particles, these suspended solids can accelerate the metal erosion of equipment, cause circulating water quality to deteriorate, and in the process, some are floating
The soluble gas such as heavy rubbish, microorganism and sulfur dioxide, hydrogen sulfide, ammonia can be also substituted into recirculated water.Cooling tower goes out
With good illumination and ventilation condition, metal erosion on the one hand can be aggravated；On the other hand, given birth to for the breeding of aerobic microbiological
Length provides good ecological environment, and the metabolite of microorganism also enters recirculated water therewith.These factors are superimposed together, and make
It is continuously improved into the ion concentration in circulation, pH, content of organics, a certain amount of concentrate had both been discharged after running a period of time,
Clear water is supplemented at the same time to maintain the normal operation of equipment, and the concentrate of generation proposes the problem of new for Treatment of Industrial Water.
Many requirements such as water-saving, energy saving, environmental-friendly will be taken into account to the processing that concentrate is arranged outside cooling circulating water.Now such as
The present, the processing to cooling circulating water mainly add medicament or treatment process in certain process procedure of cooling recirculation system, with
Scale inhibition, inhibition are as the main purpose.At present, the treatment technology used mainly has：Preservative, antisludging agent and acid adding processing；Lime is soft
Change-antisludging agent stabilization processing；Weak acid resin processing, at the same time, some processing units set side-stream treatment device, at by-pass flow
Manage device multirow drop alkali and reverse-osmosis treated.
In currently used method, processing medicament is relied primarily on, thus the spending in production process can be increased；It is quiet
Electric treatment and membrane filtration technique early investment and operational and administrative expenses are all higher.For the research in terms of row's concentrate outside recirculated water
Also it is relatively deficient, and the complete biological treatment for this kind of waste water is not proposed yet.
The content of the invention
The purpose of the present invention is to solve it is costly existing for existing refinery desulfurization wastewater treatment technology the problem of, and
It is proposed a kind of refinery Deep Processing Method of Waste Water from FGD based on BESI technologies.
Above-mentioned goal of the invention is achieved through the following technical solutions：
Step 1, for the refinery desulfurization wastewater in tank, using anti-by anaerobic organism conversion zone, facultative anaerobe
The BESI technologies that section, aerobe reaction section collectively form are answered to handle refinery desulfurization wastewater；
Step 2, take off the refinery of BESI (Biological Electron Sulfur Integration) technology water outlet
The cylindrical reactor of the embedded ultraviolet lamp of sulphur waste water injection, ultraviolet-sterilization processing is carried out to refinery desulfurization wastewater；
Step 3, using by the filter tank that coal quality activated carbon and quartz sand filter media form give up the refinery desulfurization after ultraviolet-sterilization
Water carries out filtration treatment, and will filter out last water outlet of the water as the technology, i.e., the refinery desulfurization wastewater after final process.
The invention has the advantages that：
The present invention carries out biochemical treatment first with BESI technologies to refinery desulfurization wastewater, then carries out ultraviolet-sterilization and mistake
Filter, is not only able to effectively remove the harmful substance in refinery desulfurization wastewater, and can ensure the stabilization of effluent quality.Utilize
Present invention processing refinery desulfurization wastewater recirculated water, effluent index reaches country-level A standards, while realizes mud decrement 60%,
COD≤60mg/L, TN (total nitrogen)≤10mg/L, ammonia nitrogen≤5mg/L, pollutant are degraded, and poisonous and harmful substance is reduced, and are a kind of
For the effective processing method of sulfur-containing waste water.
Existing chemicals treatment, electrostatic treatment and membrane filtration treatment technology are compared at the same time, the present invention can effectively reduce
Production cost and cost for wastewater treatment.And during using processing cycle waste water of the present invention, integrated processing can be processed into
Equipment, can realize the processing of efficient quick.
