Description
Technical field
The present invention relates to a kind of industrial production sewage treatment equipment, especially relate to a kind of employing anaerobism (UASB) method and handle high density chemical fiber waste water device.
Background technology
The waste water that produces during trevira is produced, its variation water quality is big, and COD is up to 2600mg/L, and BOD reaches 1000mg/L, and SS reaches 500mg/L, obviously belongs to high concentrated organic wastewater.Organic waste water more easily is degraded by microorganisms, and adopts bioremediation comparatively reasonable.Or handle, or with anaerobism+aerobe processing with full aerobe.See that technically the anaerobic treatment technology requires seldom the energy, volumetric loading is higher than aerobic load, take up an area of and lack, few to the nutrition demand, unit reactor volumetrical organic matter removal amount height, the mud that the anaerobism method produces is few, and the excess sludge dewatering is good, does not use dewatering agent when concentrated.But anaerobic process water outlet COD is higher than aerobic treatment, and it is slow to start reactor.The aerobic technical finesse time is short, and treat effluent COD is lower, but needs consumes energy, and management expectancy is higher, invests higher.Adopt compound treatment process-anaerobism+aerobe treatment technology, add and use the UASB high efficiency anaerobic reactor, make anaerobism+aerobic improvement waste water effect better.In the subsequent handling of this treatment unit, increase by a charcoal pond, promptly utilize the characterization of adsorption of gac, organic pollutant, microorganism and dissolved oxygen etc. in the waste water are enriched in the surface of charcoal, increase the probability of microbiological deterioration organic pollutant, prolong the organic residence time, the enhanced biological Degradation is removed the carbon surface adsorbed organic matter.
Adopt the UASB method to handle chemical fiber waste water, most COD, BOD remove in the UASB anaerobic reactor, have brought benefit to subsequent disposal, thereby save the power consumption that causes owing to oxygen supply greatly.The UASB reactor, because its sludge concentration is very high, activity is also very strong, can handle at normal temperatures, its COD volumetric loading can reach 6～8kgCOD/ (m
3D), be 3～5 times of common anaerobic reactor, also much higher than the volumetric loading of aerobic reactor.Therefore, handle the waste water of identical water quantity and quality, the required common anaerobic reactor of volumetric ratio of UASB anaerobic reactor is much smaller, also much smaller than aerobic reactor, thereby can save floor space and reduce initial cost; Not only quantity is few for the mud that anaerobic reactor is discharged, and stability better, thereby can reduce the sludge treatment expense.Most of organism in the waste water is converted into biogas, recyclable a considerable number of bioenergy.
Publication number is that the application for a patent for invention of CN101003406 discloses a kind of anaerobic-aerobic coupled pneumatic lift type circulation biochemical reactor and method for treating wastewater of chemical fiber.Support external flow guiding cylinder and inner draft tube in the body of the tower of this biochemical reactor, the outside of gas distributor in external flow guiding cylinder is enclosed within; Outer gas distributor and interior gas distributor are fixed on the bottom of body of the tower, and outer gas distributor is enclosed within the outside, bottom of external flow guiding cylinder 3, and interior gas distributor is fixed on interior gas distributor inner bottom part.The present invention is a raw material with chemical fibre industry waste water, utilize this reactor to carry out biochemical treatment, pressurized air enters reactor, and the liquid in the guide shell is moved upward, between the gap of external flow guiding cylinder and two guide shells, form big circulation, and anaerobic and aerobic are coupled.And reach emission standard.Characteristics such as that this technology has is simple to operate, convenient management, the anaerobic-aerobic effect is obvious, cost is low, biochemical treatment is effective are suitable for industrial applications.
