The described waste water of b is passed into the effluent cycle pond, removes except that large particulate matter, part suspended substance and part oil, reduces COD content;
C is passed into described waste water coagulation air-float machine oil removing slagging-off and removes ammonia nitrogen;
D is passed into the intermediate sedimentation pond with described waste water, and the impurity behind the precipitation coagulation floatation is regulated water quality simultaneously;
E is passed into described waste water and utilizes anaerobion effect in the hydrolysis acidification pool, dyes organic matter degradation and becomes the biodegradable organism of small molecules the macrobead macromole of difficult degradation in the waste water is useless;
The described waste water of f feeds contact-oxidation pool, and described waste water makes organism in the aerobic bacteria absorption and the described waste water of degrading by aeration under the catalytic oxidation effect of aerobic bacteria;
The described waste water of g recycles or qualified discharge after handling by tiltedly heavy pond precipitation and postprocessing working procedures.
It is further characterized in that:
Described effluent cycle is provided with cooling tower in the pond, is used for reducing the temperature of described waste water;
Described waste water is specially in the catalytic oxidation process of aerobic bacteria: it adopts conjugate fiber as filler, and described filler is contained in the micro porous aeration head that roots blower passes through, and described micro porous aeration head is immersed in the waste water of described contact-oxidation pool; Described roots blower carries out aeration by described micro porous aeration head, and aerobic bacteria is attached on the described filler, and under the effect of described aerobic bacteria, the organism in the described waste water finally is converted into water and carbonic acid gas by absorption, decomposition, the oxidation of microorganism; Described aerobic bacteria growth back to be aging is peeled off from described filling surface and is entered waste water, and new aerobic bacteria is grown at described filling surface again, thereby keeps the activity of whole biochemistry pool;
Described finishing sequence comprises that the upper strata liquid with described tiltedly heavy pond is passed in the decolouring pond, under the adsorption of gac, and the removal of impurity, decolouring; With the described contact-oxidation pool of mud part backflow in described tiltedly heavy pond, a part is back to belt filter press and dewaters.
After adopting technology of the present invention, after described tar product wastewater passes through preliminary sedimentation tank, effluent cycle pond, coagulation air-float machine, intermediate sedimentation pond, hydrolysis acidification pool, oxidation pond successively, tiltedly handle in heavy pond, decolouring pond, the ratio of the water BOD/COD of its discharge is improved, the concentration of ammonia and the concentration of volatile phenol are reduced, its water reaches normal emission standard, so it not only can non-pollution discharge, and can recycle.
Embodiment
Biomass gasifying furnace contains the flue gas of tar by after washing the cleaning of spray column and Wen's jar, and its waste water that cleans out mainly contains the useless things that dye such as dust, tar and volatile phenol, and waste water COD content is very high.
Embodiment:
The waste water generation is 10m3/h, and power plant moves 24 hours every day, and the daily output wastewater flow rate is 240m3/d.
The waste water quality index is as follows:
| ??PH | ??COD ??mg/L | ??BOD ??mg/L | ??SS ??mg/L | ??NH3-N ??mg/L | Tar mg/L | Phenol mg/L |
