Description
Technical field
The present invention relates to environmental project and waste water treatment engineering technical field, especially, it is related to a kind of high-concentration hardly-degradable
The processing unit and method of organic wastewater.
Background technology
The treatment of high concentration hard-degraded organic waste water, is the generally acknowledged problem of current sewage disposal circle both at home and abroad.For this kind of
Waste water, studying both at home and abroad at present more have coking chemical waste water, pharmacy waste water (including traditional Chinese medicine wastewater), petrochemical industry/oils waste water, spins
Knit/professional the waste water such as dyeing waste water, wastewater from chemical industry, paint waste water.So-called high concentration, refers to the organic concentration of this kind of waste water
(in terms of COD) is higher, and generally in more than 2000mg/L, even as high as every liter for having is tens of thousands of to ten tens of thousands of milligrams；So-called difficult drop
Solution, refers to that the biodegradability of this kind of waste water is relatively low (BOD5/COD values are even lower generally below 0.3), it is difficult to biology drop
Solution.So, the organic wastewater generally by COD concentration more than 2000mg/L, BOD5/COD value less than 0.3 is collectively referred to as highly concentrated in the industry
Degree organic wastewater with difficult degradation thereby.Due to high concentration hard-degraded organic waste water produce and itself the characteristics of attribute, have following main danger
Evil：
One is aerobism harm：Due to biodegradation, high concentrated organic wastewater can make receiving water body anoxic or even detest
Oxygen, most aquatic organisms are by death, so as to produce stench, deteriorate water quality and environment；Two is sense organ contact scar：High concentrated organic wastewater
Water body is lost use value, more have a strong impact on the normal life of the nearby water bodies people；Three is causing toxicity harm：Superelevation is dense
Contain a large amount of toxic organic compounds in degree organic wastewater, can constantly be accumulated in the natural environments such as water body, soil, stored, it is most laggard
Enter human body, be detrimental to health.
High concentration hard-degraded organic waste water treatment technology can be divided three classes：Materializing strategy technology, chemical treatment method and
Biologic treating technique.
1st, materializing strategy technology
Physico-chemical process is applied to treatment of Organic Wastewater frequently as a kind of means of pretreatment, and the purpose of pretreatment is by reclaiming
Useful component in waste water, or some difficult for biological degradation things are processed, so as to reach organics removal, biochemical is improved,
Biochemical treatment load is reduced, treatment effeciency is improved.General conventional physico-chemical process has extraction, absorption method, concentration method, ultrasonic wave to drop
Solution.
2nd, chemical treatment method
Chemical treatment method is that the pollutant component in waste water is converted into harmless object by applied chemistry principle and chemical action
Matter, makes the method that waste water is purified.Chemical oxidization method is divided into two major classes, and a class is to utilize strong oxidizer at normal temperatures and pressures
(such as hydrogen peroxide, potassium permanganate, hypochlorite, ozone) is by the oxidation operation in waste water into carbon dioxide and water；It is another
Class is organic matter in Decomposition Wastewater at high temperature under high pressure, including supercritical water oxidation and wet-air oxidation technique, oxidation used
Agent is usually oxygen or hydrogen peroxide, general to use catalyst degradation reaction condition, accelerates reaction rate.Chemical oxidization method reacts
Speed is fast, control is simple but relatively costly, is generally difficult to for the step of organic matter one of difficult degradation to be oxidized to inorganic substances, and mesh
The research of the preceding control to intermediate product is less.The technology is also used often as the preprocess method of biochemical treatment.Its is main
Method have burning method, Ozonation, electrochemical oxidation process etc..
3rd, biologic treating technique
Biological treatment is the main technique of purification of waste water, mainly for the treatment of the organic waste of the industries such as agricultural chemicals, printing and dyeing, pharmacy
Water.Biological treatment be decomposed using the metabolism of microorganism, the toxic and harmful substance that converts in water body and other
The biotechnology of various exceeded components, the place of degradation is mainly the activated sludge containing microorganism, biomembrane and its corresponding
Reactor, be thus born different kind organism treatment technology.Microbial method is not only economical, safety, and the dirt for processing
Dye thing threshold value it is low, residual less, non-secondary pollution, have preferable application prospect.According to the difference of reaction condition, microorganism treatment
Aerobic biological process and the major class of anaerobic bio-treated two can be divided into.
At present, the processing method for more generally using is substantially biologic treating technique, and materializing strategy and chemical treatment
Based on pretreatment or advanced treating supplement, in the hope of reaching preferable degree for the treatment of.But the place of high-concentration hardly-degradable waste water
Reason, generally acknowledged problem is turned into because of the particularity of waste water, except high disposal cost and high maintenance administration fee under conditions of, it is difficult to
Every profession and trade relevant emission standards are met by the above method.
