Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, be a kind of suspended biological filler activating and regenerating of the present invention device, comprise device for removing scum 5, filtration unit 13 and washing unit 11.In described device for removing scum 5, remover is housed, the filler 1 dried can be put into and wherein carry out pre-demoulding, make the microbial film partial exfoliation on filler 1 surface.Also be provided with mechanical stirrer 4 in this device for removing scum 5, can stir remover, improve demoulding efficiency.Described filtration unit 13 top is provided with screen cloth 6, and bottom is provided with the intercepting basin 8 of band valve 9.After precipitating containing the biomembranous remover that comes off in this intercepting basin 8, releasing agent is made to become clarification.Be provided with transfer tube between described intercepting basin 8 and device for removing scum 5, and this transfer tube being provided with reflux pump 7, can the remover after clarification being fed back in device for removing scum 5, in order to reusing.The in-built clear water of described washing unit 11, meanwhile, its inside is also provided with a reciprocating vibration sieve 10 and 2 ultrasonic generators 12, can to filler 1 demoulding further.
In above-mentioned device for removing scum 5, the pH value of institute's removable film is 5 ~ 5.5, is configured form by HCl and tensio-active agent.This tensio-active agent is Sodium dodecylbenzene sulfonate, 0.05 ~ 0.15 times that the amount (unit: Kg) of tensio-active agent is packing volume (unit: m3).Remover volume is 3 ~ 4 times of packing volume.The stir speed (S.S.) of the mechanical stirrer 4 filled in device for removing scum is 80 ~ 100rpm.The stirring reaction time is 12 ~ 15h.
The frequency of described vibratory screening apparatus 10 is 200 ~ 300 beats/min, and the frequency of 2 ultrasonic generators 12 is 25 ~ 30KHz.The clear water of 2 ~ 3 times of packing volumes is housed in described washing unit 11, and the treatment time is 1 ~ 3h.
The aperture of above-mentioned screen cloth 6 and vibratory screening apparatus 10 is 10 ~ 12mm.
The process of activating and regenerating method of the present invention is: used by the floating stuffing 1 of inactivation filler fishing device 3 to salvage out from sewage lagoon 2, (this fishing device 3 can use patented product: granular biological filler fishing device, the patent No.: 200920257145.4), puts into device for removing scum 5 and carries out pre-demoulding after drying; Then filler is salvaged out from device for removing scum 5, and put into filtration unit, by screen cloth 6, remover and the microbial film that comes off are separated with filler, and make to be mixed with biomembranous remover and enter intercepting basin 8 and carry out clarifying treatment.Microbial film after precipitation is discharged by valve 9, and the remover after clarification is then fed back to device for removing scum 5 by reflux pump 7 and again utilizes.Finally, the filler of pre-demoulding drops into washing unit 11, utilizes ultrasonic wave to carry out further demoulding, completes the regeneration of floating stuffing.
Be below a specific embodiment:
Certain pharmacy sewage treatment plant, the water yield is 6000 ~ 8000t/d, and principal pollutant are vitamins C, inlet COD concentration 2000 ~ 3000mg/L, and adopt MBBR technique to process, hydraulic detention time is 8 ~ 10h.Because calcium ions and magnesium ions concentration in water inlet is higher after operation for some time, form inactive mud at filling surface, cause the increase of filler proportion to sink at the bottom of sewage pool, filler stream voltinism is deteriorated, and processing efficiency reduces.By 150m
3filler is salvaged out (can use patented product: granular biological filler fishing device, the patent No.: ZL200920257145.4) and is dried from reflection pond.Then drop into device for removing scum, in device for removing scum, remover is housed, releasing agent is primarily of HCl solution and Sodium dodecylbenzene sulfonate composition, and the volume of remover is 400m
3, the pH of remover controls to be about 5.5, and the dosage of Sodium dodecylbenzene sulfonate is 8Kg, uses mechanical stirrer to stir 12h, finds that a part of microbial film starts demoulding.Salvaged in screen cloth by filler after stirring completes, remover and microbial film enter intercepting basin after filtration, drain through precipitating the microbial film of rear demoulding, reclaim in the device for removing scum that the remover in intercepting basin is back to through reflux pump.Filler after screen filtration, drops into the vibratory screening apparatus in ultrasonic cleaning equipment, in ultrasonic cleaning equipment, 400m is housed
3clear water, vibrational frequency is 240 beats/min, and the frequency of hyperacoustic producer is 28KHz, treatment time 2h.Filler after supersound process is pulled out and is dried from reactor, detects filler effective ratio area, finds that the specific surface area of filler after regeneration is 430 m
2/ m
3, be 86% of new packing specific area, new packing specific area is 500 m
2/ m
3.By the filler after regeneration for the treatment of municipal sanitary sewage, find that the clearance of COD can reach 86%, ammonia nitrogen removal frank can reach 95%, illustrates that filler still has good contaminant-removal properties after regeneration.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
