Specific embodiment
The present invention is further described below combined with specific embodiments below.
Embodiment 1
A kind of printing and dyeing wastewater processing equipment of the present embodiment, including grid, adjust sedimentation basin, flotation tank, hydrolysis acidification pool,
Intermediate pool, SBR biochemistry pool, discharge pond, sludge concentration tank and accident pool, dyeing waste water pass sequentially through filter device, adjust and sink
Shallow lake pond, flotation tank, hydrolysis acidification pool, intermediate pool, SBR biochemistry pool and discharge pond；Sedimentation basin is adjusted for adjusting precipitating to drop
Low COD and BOD5；It is equipped with elastic filler in hydrolysis acidification pool and forms packed bed, for the organic matter in dyeing waste water of degrading；Gas
Sludge in floating pond and SBR biochemistry pool is discharged into sludge concentration tank.Discharge pond is connected by accident pool with sedimentation basin is adjusted, and thing is arranged
Therefore the main reason for pond is easily to generate punching to waste water disposal facility in view of dyeing waste discharge feature and dump
It hits, sets up accident pool to be buffered, guarantee the effect of waste water treatment.
Using a kind for the treatment of method of printing and dying wastewater of the present embodiment of above-mentioned apparatus, handled object is to be mixed with life dirt
The dyeing waste water of water, and do not contain phenols, heavy metal salt, biostatic agent and chemical attack product, the correlation of water quality and quantity
Index is shown in Table 1.
Water quality, the water of waste water handled by 1 embodiment 1 of table
As shown in Figure 1, waste water to be processed is removed large granular impurity by grid filtration, adjusting precipitating is then passed sequentially through
Pond, flotation tank, hydrolysis acidification pool, intermediate pool and SBR biochemistry pool then drain into discharge pond, handle after materializing strategy is up to standard
It completes, waste water residence time in adjusting sedimentation basin is 48h, and the residence time in hydrolysis acidification pool is for 24 hours.
The principle of the hydrolysis acidification pool of the present embodiment is：The anaerobic biodegradation process of material is divided into four-stage.First is that
Hydrolysis stage, microorganism complete bio-catalytical oxidation by discharging extracellular free enzyme or being connected to the immobilized enzyme on mantle
It reacts (refer mainly to macromolecular substances and be decomposed into small molecule and its hydrotrope)；Second is that fermentation (or acidification) stage, acidification bacterium will be upper
It states small molecule to be converted into more simple compound and be secreted into extracellularly, primary product has volatile fatty acid, alcohols, lactic acid
Deng；Third is that producing the acetic acid stage, refer to that product is converted further as acetic acid, hydrogen, carbonic acid and new cellular material on last stage；Four
It is the methane phase stage, refers to that product is converted into methane, carbon dioxide and new cellular material on last stage.Water in the present embodiment
Solution acidification just allow for methanogen with hydrolysis the acid-producing bacteria speed of growth it is different, by Anaerobic Treatment control it is shorter in the reaction time
The first and second stage of Anaerobic Treatment, i.e., a large amount of hydrolytic bacterias, acidification bacterium effect under by insoluble hydrolysis of organic matter be it is molten
Solution property organic matter, converts the macromolecular substances of difficult for biological degradation to the process of the small-molecule substance of easily biological-degradable.
Control SBR biochemistry pool the method for operation be specially：Water inlet operating method：A pond SBR inlet valve is first opened, it is closed
Start to intake after his pond SBR inlet valve；Two pond SBR inlet valves are opened, SBR inlet valve is turned off into after full water in the pond SBR
Door.Being aerated operating method is：It is aerated in water inlet, aeration time opens another pond aeration valve after reaching 8 hours, close aeration
Valve.Precipitating checked situation in pond after 1 hour, and the limpid water decanter that can just open of water is drained, and water is discharged into discharge
Pond.The cycle of operation in the entire pond SBR is about 12h, including water inlet 2h, is aerated 8h, precipitates 1h, strain water 1h, the steam-water ratio in the pond SBR is
1：15.
The sludge in sludge concentration tank is concentrated using belt filter press, filters pressing, is pressed into mud cake outward transport；Below standard
Waste water enters adjusting sedimentation basin by accident pool and is reprocessed.
2 are shown in Table by the correlation water index of the present embodiment treated waste water, illustrates that final outflow water water quality is fully met
《Jiangsu Province's textile dyeing and finishing industrial water pollution discharge standard》The requirement of (DB32/670-2004).
The water quality indicator of 2 embodiment of table, 1 processed waste water
