Part, through circulating washing postcooling discharge at high temperature, therefore component is extremely complex and extensive in waste water, and waste water it is every into
Point with feed coal component, gasification operating mode and operating condition change and change, lump coal pressure gasification process technology maturation application
Extensively, but in fixed bed gasification, the coal gas of gasification layer forms raw gas after destructive distillation layer, drying layer with destructive distillation component, this
During raw gas gradually cool down, so produce waste component it is complicated and changeable, main external appearance characteristic：Dark brown, have viscosity, be more
Foam.PH value is more than 7 but unstable, can reach more than 10, has strong phenol ammonia odor, general COD value is in 5000mg/L
Left and right, 2500~7000mg/L of ammonia nitrogen concentration, oil content 800mg/L or so.Both at home and abroad generally using separation and biological treatment phase
With reference to handling such waste water.Chemical separating includes the unit processes such as absorption, extraction, rectifying, UF membrane, to remove sour gas
The materials such as body, recycling phenol, ammonia, sulphur, then biological treatment is carried out, but cannot reach emission request.
At present, the technology of domestic processing gasification of poor coal waste water also has following several.

It is poor to the patience of oils.
（2）HSB methods handle waste water
HSB (High Sotution Bacteria) is the english abbreviation of macromolecule flora.Country's preliminary test obtains at present
Go out to draw a conclusion：Poisonous and harmful substance is good in HSB tolerance waste water, and sludge is few after processing, effluent color dilution is good, and caustic dosage is tradition
The 1/3~1/5 of method, operating cost is relatively low, but strain properties, life condition, purification function are not yet understood completely, need into
One step research and practice.
（3）Anaerobic biological process handles waste water
Anaerobic Microbiological Treatment Technology utilizes the metabolism and characteristic of anaerobe, without adding external source energy, with quilt
The organic matter of reduction produces biogas as hydrogen acceptor while degradation of organic substances.Organic matter during anaerobic bio-treated
Degradation pathway can be divided into hydrolysis, fermentation and acid, production acetic acid production hydrogen and methane phase four-stage.In actual moving process, anaerobism work
Skill is limited to COD and ammonia nitrogen removal ability, but the small molecule that waste water forms a large amount of easily biological-degradables after Anaerobic Treatment is organic
Thing, can significantly improve wastewater biodegradability and aerobic degradability.
（4）Electrochemical catalytic oxidation treatment technology
The technology is by the metal oxide electrode with catalytic performance, produces the hydroxyl free with Strong oxdiative ability
Organic pollution in base or other free radicals attack solution, makes it be completely decomposed into harmless H2O and CO2, the technology into
Maturity also needs to the test by engineering practice.
Processing to gasification of poor coal waste water, is handled merely by the method for physics, physical chemistry, chemistry, biology, difficult
To reach discharge or reuse standard, generally require to combine by several processing methods, can be only achieved the degree of processing requirement.Therefore
Need be continuously improved prior art disposal ability, various methodological sciences are reasonably combined, deposit it is excellent rogue just find control
Manage the best approach of gasification of poor coal waste water.
