Description
Technical field
The invention belongs to petro-chemical waste water treatment technical field, relate to dividing with biomembrane reaction district, pretreating zone film
A kind of dual-membrane type wastewater treatment equipment constituted from reaction zone ultraviolet ray sterilizer.
Background technology
Petrochemical industry is the important component part of chemical industry, plays an important role in the development of national economy, is China
One of pillar industry department.Petrochemical industry refers to oil and natural gas as raw material, produces oil product and petrochemicals
Processing industry.Oil product also known as oil product, mainly include various fuel oil (gasoline, kerosene, diesel oil etc.) and lubricating oil and
Liquefied petroleum gas, oil coke, paraffin, Colophonium etc..The course of processing producing these products is commonly referred to as petroleum refining, is called for short refining
Oil.The further chemical process of raw oil that petrochemicals provide with oil refining process obtains.Produce the of petrochemicals
One step is that gentle to raw oil (such as propane, gasoline, diesel oil etc.) crack, and generates with ethylene, propylene, butadiene, benzene, first
Benzene, dimethylbenzene are the basic chemical raw materials of representative.Second step is to produce multiple Organic Chemicals (about with basic chemical raw materials
200 kinds) and synthetic material (plastics, synthetic fibers, synthetic rubber).The production of this two steps product belongs to the scope of petrochemical industry.
Organic Chemicals continues processing can prepare the chemical products of more multi items, is not belonging to the scope of petrochemical industry traditionally.Having
In a little data, with natural gas, light gasoline, heavy oil for Material synthesis ammonia, carbamide, even produce nitric acid and also list petrochemical industry in.Existing
Its thorough process can not just be discharged it by some petrochemical wastewaters when processing, and causes the pollution of environment, waste resource
Pollute environment simultaneously.
Known membrane bioreactor wastewater processing technology, English abbreviation " MBR " technology, is in recent years from the one of external introduction
Planting the advanced technologies being widely used in treatment of Organic Wastewater, this membrane bioreactor typically uses activated sludge+hollow-fibre membrane
Combining, i.e. monofilm formula biological reaction process, owing to this technological process is simple, high treating effect, retaining power is strong, water outlet water
Of fine quality, obtain good popularization and application and tremendous development at home, but this technique is in same due to membrane module and waste water
Working cell, mixes with sewage sludge, along with membrane separating process is carried out, the microorganism that is rejected by waste water getting off,
Pollutant, float gradually increase, and activated sludge process is owing to response procedures is excessively simple, oxygen transformation efficiency place low, biochemical
Reason ability, it is impossible to the organic pollution in sewage is effectively dissolved removal, causes sludge concentration constantly to increase, and film fiber tube is long
Phase dip this high concentration, high pollution waste water in, it is easy to be contaminated causing the blocking of film, have a strong impact on membrane module
Work efficiency and service life.To this end, present inventors have proposed a utility model patent: a kind of Double-film type water treatment technical dress
Put, Chinese patent ZL200720156269.4.This patent replaces activated sludge process with the i.e. technology of biological membrane of immobilized microorganisms,
The defect and the deficiency that make above-mentioned technique are well solved, and this patent process unit is mainly by casing, biomembrane filtering layer, film group
Part, going out water pump, ultraviolet ray sterilizer etc. and constitute, biomembrane filtering layer is by the filter of the multiple concrete dynamic modulus such as zeolite, haydite, coke, activated carbon
Material composition, then cultivate through biotechnology to form biomembrane, cut dirt by the physics of biomembrane filtering layer and biological adsorption is dissolved, go out
Water is by row outer after ultraviolet ray sterilizer sterilization or reuse, in above-mentioned patented invention, although use immobilized microorganisms
Replace conventional activated sludge method, make treatment effeciency and film be improved and improve service life, but on the present inventor
In the patented technology stated, biomembrane filtering layer and membrane module fail still in same working environment, biological respinse and film separation reaction
Effectively separate, the mud that on the one hand produces in bioprocesses, do not dissolve the impurity such as Organic substance and remain to enter in membrane module and join
The most constantly building up with the course of reaction of film, the on the other hand pollutant under membrane module retains, water quality constantly deteriorates, the most at last shadow
Ring the safety run to film and stable, this situation in drinking water source, the low concentration sewage such as sanitary sewage and hospital sewage
In process, the harmful effect to membrane module is less, and membrane module is in the range set for it and remains in the time limit normally work,
But the petrochemical organic wastewater more complicated for such as water quality is administered, and the harmful effect running film is the most serious,
Thus above-mentioned patented technology is in the application that waste water processes, there are still certain limitation and weak point.
