Description
Technical field
The present invention relates to refinery method for treating desulfurized wastewater.
Background technology
Recirculated water constantly can evaporate at cooling tower in the process back and forth used, and causes dissolved matter in water coolant and solid particulate is constantly concentrated.In open type circulating water cooling system, water coolant is converted into hot water after overcooling interchanger, sprays downwards at cooling tower, forms countercurrent mass transfer effect, thus cooled with upwards flowing air.In the process of this heat exchange, air produces stripping effect to water coolant, the carbonic acid gas in water coolant is overflowed, causes the pH of water coolant to raise, the risk of fouling in this system is increased.The suspended particle of water coolant after heating in the process sprayed downwards in meeting wash-out air, these suspended solidss can accelerate the metallic corrosion of equipment, circulating water quality is caused to worsen, in the process, the soluble gas such as some rubbish that drift along, microorganism and sulfurous gas, hydrogen sulfide, ammonia also can by substitution recirculated water.Cooling tower goes out to have good illumination and ventilation condition, can aggravate metallic corrosion on the one hand; On the other hand, the flourish for aerobic microbiological provides good ecotope, and the meta-bolites of microorganism also enters recirculated water thereupon.These factors are superimposed together, the ionic concn in circulation, pH, organic content is caused to improve constantly, both discharged a certain amount of concentrated solution after running for some time, supplement clear water to maintain the normal operation of equipment, the concentrated solution of generation is that Treatment of Industrial Water proposes new problem simultaneously.
The process of arranging concentrated solution outward to cooling circulating water will take into account many requirements such as water saving, energy-conservation, environmental friendliness.Nowadays, mainly medicament or treatment process are added, with scale inhibition, inhibition for main purpose at certain process procedure of cooling recirculation system to the process of cooling circulating water.At present, the treatment technology of use mainly contains: sanitas, Scale inhibitors and add acid treatment; Lime soften for sewage-Scale inhibitors stabilizing treatment; Weak acid resin process, meanwhile, some treatment unit arranges side-stream treatment device, and alkali and reverse-osmosis treated fall in parallel seismic method device multirow.
In currently used method, main dependence processes with medicament, thus can increase the spending in production process; Electrostatic Treatment and membrane filtration technique early investment and operational and administrative expenses all higher.The research of arranging concentrated solution aspect for recirculated water is outward also relatively deficient, and does not also propose the complete biological treatment for this kind of waste water.
Summary of the invention
The object of the invention is the problem costly existed to solve existing refinery desulfurization wastewater treatment technology, and propose a kind of refinery Deep Processing Method of Waste Water from FGD based on BESI technology.
Above-mentioned goal of the invention is achieved through the following technical solutions:
Step 1, for the refinery desulfurization wastewater in tank, the BESI technology be jointly made up of anaerobe conversion zone, facultative anaerobe conversion zone, aerobe conversion zone is adopted to process refinery desulfurization wastewater;
Step 2, the refinery desulfurization wastewater of BESI (BiologicalElectronSulfurIntegration) technology water outlet is injected the cylindrical reactor of embedded ultraviolet lamp, ultraviolet-sterilization process is carried out to refinery desulfurization wastewater;
Step 3, use the filter tank be made up of ature of coal activated carbon and quartz sand filter media to carry out filtration treatment to the refinery desulfurization wastewater after ultraviolet-sterilization, and the last water outlet of water outlet as this technology will be filtered, the refinery desulfurization wastewater namely after final process.
The present invention has following beneficial effect:
First the present invention utilizes BESI technology to carry out biochemical treatment to refinery desulfurization wastewater, then carries out ultraviolet-sterilization and filtration, not only effectively can remove the objectionable impurities in refinery desulfurization wastewater, and can ensure the stable of effluent quality.Utilize process refinery desulfurization wastewater recirculated water of the present invention, effluent index reaches country-level A standard, realize mud decrement 60% simultaneously, COD≤60mg/L, TN (total nitrogen)≤10mg/L, ammonia nitrogen≤5mg/L, pollutent is degraded, hazardous and noxious substances reduces, and is a kind of for the effective treatment process of sulfur-containing waste water.
Compare existing chemicals treatment, Electrostatic Treatment and membrane filtration treatment technology, the present invention can effectively reduce Productive statistics cost and cost for wastewater treatment simultaneously.And when utilizing cycle for the treatment of waste water of the present invention, the treatment facility of integration can be processed into, the process of efficient quick can be realized.
