Technical field
The present invention relates to Waste Disposal Technology field, and in particular to a kind of cement kiln collaboration handles organic abraum salt, high salt
The method and system of organic wastewater.
Background technology
Cement kiln collaboration processing solid waste technology refers to by high temperature incineration and cement clinker mineral high temperature sintering
Process, realizes the Waste disposal means for the purpose of solid waste poisons ingredient breakdown, degraded, elimination, deactivation and steadyization.It has
Have applied widely, consumption amount it is big, to various wastes again very strong adaptability, thermal capacity is big, thermal inertia is big and heat transfer effect
The high technical advantage of rate, at present, cement kiln synergic processing solid waste technology are also developed rapidly.
High salt organic waste water and organic abraum salt are mainly derived from chemical industry, pharmacy, food processing, printing and dyeing, saponin, oil are opened
The waste water or byproduct adopted, discharged in the industry production such as papermaking and pesticide.Due to economic continuous development, high salt organic waste water and
The total amount of organic abraum salt is huge and has increased trend year by year, in high salt organic waste water and organic abraum salt be mainly salt (such as NaCl,
Na2SO4Deng) in absorption it is substantial amounts of be difficult to natural degradation poisonous organic matter (such as benzene class, amine, phenols, resinae, ethers,
Phenols etc.), hazardous waste is defined as by environment department, soil and water system will such as be damaged without effectively processing, it is organic
The volatilization of thing will lead to extremely serious environmental disaster.
High salt organic waste water and organic abraum salt difference lies in：High salt organic waste water is organic abraum salt containing large quantity of moisture
Solution, organic abraum salt are the relatively low solid waste of water content.It is organic abraum salt after high salt organic waste water dehydration.High salt organic waste
Disposal of the water than organic abraum salt adds large quantity of moisture and removes out this great difficult problem.Therefore, in water resource increasingly short today,
Actively inquire into the treatment technology of effective high salt organic waste water and organic abraum salt has become the hot spot neck that fixed-end forces are studied
Domain and technical barrier.
At present, high salt method for processing organic wastewater is related to burning method, deep oxidation method, leaves exchange process, electrochemical process, film
The physical chemistry such as partition method, bioanalysis and bioremediation.These methods all have certain feasibility in theory, but by
In the complex chemical composition of high salt organic waste water, moisture content is high, and preferable target is unable to reach during actual implementation.
Wherein, handling high salt organic waste water using bioid has relatively low cost of disposal, but when salt content in brine
During more than 1%, it is very difficult for maintaining suitable biological growthing environment, stablizes fortune for the chronicity of biological treatment system
Row brings risk.
Using the technology of electrolysis and UF membrane etc, since high salt organic waste water is not pure brine, also containing complexity
Other impurities, seriously affect separating effect, simultaneously as pipeline is complicated, easily blocks or film is failed.The cost of equipment
Height, investment is big, and processing cost is high.
Using burning method make the organic matter in high salt organic waste water under 800-1000 DEG C of hot conditions with air
Oxygen carries out vigorous reaction, and release energy and produce high-temperature combustion gas and the solid residue of property stabilization, is highly effective money
Source processing mode.But mass energy is needed using burning method evaporation flood tide moisture content, operating cost is high, simultaneously as burning
Contain Cl in gas-And organic matter, it is possible to which there are bioxin, and exhaust treatment system is complicated, and there are the potential wind of secondary pollution
Danger.
CN201611095267.9 discloses a kind of method for handling high salt organic waste water, by concentration salt extraction and biochemical treatment
Combine, substep removes inorganic salts and organic matter, realizes the qualified discharge of waste water.Particular technique step is：To being heated to 40-
Dehydrating agent is added in 80 DEG C of waste water until waste water saturation, is cooled to -5~5 DEG C, precipitation mixing salt crystal will by saturation waste water
Crystallization waste water centrifugal, which separates, must mix salt crystal and high organic matter concentrated mother liquor, and mixing salt crystal is washed to obtain dehydrating agent hydrate
Crystal, washing mother liquid evaporation concentration salt extraction, dehydrating agent hydrate crystal are heated to 95-150 DEG C and turn crystalline substance and be dehydrated that dehydrating agent must be regenerated
And condensed water, high organic matter concentrated mother liquor obtain the high organic matter concentrated mother liquor of saliferous through 3-5 concentration salt extraction, the high organic matter of saliferous is dense
Contracting mother liquor carries out biochemical treatment after being diluted with condensed water, obtains waste water up to standard.The patent uses the technology that biochemical treatment combines, raw
Thing residue may be chronically in water body, and the influence to environment can not be completely eliminated, and have certain limitation.
CN201710205937.6 is related to a kind of processing method of high salt organic waste water, belongs to field of waste water treatment；Mainly
Solve the problems, such as mutually to tie with biochemical treatment using resin adsorption, multiple-effect or MVR evaporations containing high salt and high organic wastewater, method
The mode of conjunction handles waste water, the removal rate of salt and COD has been reached more than 99.5%；Using the very big journey of resin adsorption
The active ingredient in waste water can be recycled on degree, while the content of organic matter in salt can be reduced, follow-up life can also be reduced
Chemical conversion is originally；Salt content in waste water can be reduced by evaporating desalination, waste water is carried out biochemistry.The patent is used at biochemistry
