Description
Technical field
The present invention is a kind of processing method of coking wastewater, belongs to field of environment protection.
Background technology
Coking wastewater is the waste water generated in raw coal high-temperature retorting, gas purification and chemical products subtractive process, master
It wants there are three sources：First, remained ammonia, it is the waste water generated in the dry distillation of coal and coal gas cooling, and water accounts for coking
More than half of waste water total amount is the main source of coking wastewater；Second is that the waste water generated during gas purification, such as
Gas end-cooling water and crude benzol separation water etc.；Third, in the subtractive processes such as tar, crude benzol and other occasions generate waste water.Coking
Waste water is the industrial wastewater containing a large amount of persistent organic pollutants, and complicated component contains a large amount of phenol, cyanogen, benzene, ammonia nitrogen etc.
The coking wastewater of poisonous and harmful substance, discharge beyond standards causes serious pollution to environment.
Currently, domestic, there are about 50% coke-oven plants to handle waste water using traditional aerobic sludge method, although the phenol of water outlet, cyanogen,
BOD5Discharge standard is basically reached, but is difficult up to standard always to ammonia nitrogen and CODcr values.And since the ingredient of coking wastewater is multiple
Miscellaneous, biodegradability is poor, and intractability is big, and the wastewater treatment structures is made to take up a large area, and investment and processing cost are high, are engineerings
Main problem present in implementation process.
Therefore, the Treatment process of coking wastewater is improved, it should on the basis of its is up to standard, engineering throwing can be reduced
Money, operating cost and its floor space.
Invention content
The object of the present invention is to provide a kind of high treating effect, simple to operate, investment and operating cost are low, take up an area face
The small and easy to implement coking waste water treatment method of product.
The present invention is achieved through the following technical solutions：A kind of processing method of coking wastewater includes mainly that EHBR is coupled
Biofilm system+AOPSDevice is mainly made of EHBR membrane modules, membrane module frame and air supply system, and AOPSSystem is one
Body makeup is set, and installation is more convenient.
The core of EHBR membrane modules is made of hollow-fibre membrane.The hollow-fibre membrane of EHBR membrane modules has excellent
There is the outer surface of different permeability energy, good stability and mechanical strength, hollow-fibre membrane good biology to hang
Film properties；In EHBR membrane modules, the both ends of hollow-fibre membrane are fixed in component end socket or one end is fixed in component end socket
The other end be dead end or it is crack put, proper alignment is in structures；AOPSIntegrated apparatus can be placed in around structures or structure
It builds at the top of object, it is easy for installation flexible.
Membrane module frame is for fixing EHBR membrane modules, one or more EHBR being fixed on a membrane module frame
Membrane module.Air supply system is primarily referred to as air with pressure source and source of oxygen and air feed equipment, and air feed equipment is primarily referred to as including such as
The air feed equipments such as gas compressing equipment, oxygen generating plant, and the pressurized vessel containing compressed air and oxygen.Equipped with EHBR film groups
The membrane module frame of part is mounted in processing structures, AOPSIntegrated apparatus can be installed according to field condition, can construct
Around object or top, air supply system pass through gas piping and membrane module and AOPSDevice is connected.
Using this method, including：According to raw water quality and water calculate the quantity of EHBR membrane modules, design membrane module frame,
The structure snd size and AOP of structuresSThe volume and catalyst amount of integrated apparatus；According to calculating and design content, first
Structures construction is carried out, after the completion of structures, membrane module frame and membrane module, AOP are installed inside itSIntegrated apparatus can basis
Field condition is installed to suitable position or structures, and floor space is saved.By gas piping by air supply system and film group
Part and AOPSSystem is connected；It opens air supply system and is pressurized oxygenation to hollow-fibre membrane, due to its good selective permeability
Doughnut film outer surface can be made to maintain higher oxygen concentration, the microorganism in water body adheres in hollow fiber membrane surface to be given birth to
It is long, then cultivate complete biomembrane；Due to the particularity of offering oxygen way, biomembrane will appear functional layering and form life
Object chain；The biofilm process of hollow-fibre membrane outer surface biomembrane can also be accelerated by additional strain and nutritional ingredient；
During EHBR coupled biological membranous systems handle waste water, the polluter of the bio-degradable in water body by hollow-fibre membrane outside
The biomembrane of side surface adsorbs and degradation, it is difficult to enter AOP by the organic matter of biochemical degradationSSystem, by powering to electrode, sun
Pole aoxidizes or anode reaction generates the intermediate material with strong oxidation or the intermediate reaction except anode reaction occurs, and is urging
Make to be handled pollutant under agent synergistic effect and aoxidize, is finally reached the purpose of oxidative degradation pollutant.
By above-mentioned processing step, the various contamination indexes of coking wastewater are attained by emission request, and than traditional work
The floor space of skill is small, and investment and operating cost are low, and operates simpler.
