4 +-N, P have good removal effect.Gas blower intermittence from bottom membrane cisterna to aeration in it, form short-cut denitrification, facilitate the removal of pollutent, particularly NH greatly
4 +the removal of-N, P.Sewage after process passes through water pump lifting and discharges; Active sludge is very serious for film blocking, when fouling membrane is serious, carries out air-water backwashing when the rate of output water is not up to standard by gas blower and backwashing pump to the membrane module in membrane cisterna; Because supersound process has good effect for alleviation fouling membrane, therefore, carrying out Ultrasonic Radiation by opening ultrasonic generator in operational process, reducing fouling membrane; PH and ORP value in real-time detection sewage, and by regulating gas blower and backwash pump to regulate pH and ORP in time in regime values.When microorganism concn in membrane bioreactor reduces, suitably increase the Ultrasonic Radiation time, supersound process is conducive to microorganism growth, microbial dehydrogenation enzymic activity simultaneously, be conducive to improving permeability of cell membrane, improve microbial assimilation ability to function, thus increase microorganism concn.
Therefore, the utility model have employed the waste disposal plant that a kind of like this ultrasonication and membrane reactor be combined with each other, it comprises equalizing tank and membrane reactor, and the connecting tube of equalizing tank and membrane reactor is provided with the lift pump for being delivered into by the sewage lifting in equalizing tank in membrane reactor; Membrane module is provided with in membrane reactor; It is also provided with ultrasonic generator for producing Ultrasonic Radiation in membrane reactor and goes out water pump for what the sewage after process is promoted from membrane reactor discharge.
Gas blower and the backwashing pump for carrying out air-water backwashing to the membrane module in membrane reactor is provided with bottom membrane reactor.The pH probe for detecting pH and the ORP value in membrane cisterna sewage in real time and ORP probe is provided with at membrane reactor top.
Membrane reactor of the present utility model is MBR membrane bioreactor, and it can keep the microorganism of high density, and mud is long for age, and automatic operating degree is high, the load of resistance to flushing.Membrane bioreactor adopts immersion vacuum tunica fibrosa, by optimizing the operation condition of membrane bioreactor: DO is at 0.5mg/L, HRT is at 2h, SRT is 30d, makes membrane module that more excellent membrane filtration effect can be had at low temperatures to deal with the present situation of the microbiological treatment performance reduction that low temperature brings.
In view of low-frequency ultrasonic waves is at the premium properties of low temp area sewage disposal, the utility model have employed intensified by ultrasonic wave process Membrane Bioreactor for Wastewater Treatment effect simultaneously.In order to reinforced film biological reactor has better pollutant removal in low-temperature sewage situation, in placement membrane module pond, ultrasonic generator is installed, ultrasonic frequency is at 28kHz, low frequency ultrasound process water temperature slightly improves, supersound process can improve enzymic activity simultaneously, optimize microorganism cells permeability, be conducive to microorganism growth thus reinforcing microorganism to degrade pollutent usefulness simultaneously.
The beneficial effects of the utility model are:
One is that membrane bioreactor has good solid-liquid separation effect, and content of microorganisms is high, and excess sludge is few, and treatment effect is good.Meanwhile, membrane cisterna structure is simple, and it is convenient to run, and floor space is little, pH and the ORP probe that membrane cisterna inside is installed detects MBR internal operation situation in real time, thus realizes the object of automatic operating.
Two to be that low-frequency ultrasonic waves is conducive to overcoming the microorganism active that low temperature brings low, and the drawback of degradation efficiency difference, low-frequency ultrasonic waves energy consumption is low, improves microbiological treatment processing efficiency.The cavatition that supersound process produces simultaneously can improve enzymatic reaction and microbial growth and metabolism is movable, promotes the pollutent usefulness of microbiological deterioration domestic sludge.
