Description
[technical field]
The present invention relates to biological sewage treatment oxygenation technical field, in particular, is a kind of micro-bubble self-closing aerator (or claim: micro-bubble is the blocking aeration device not) of novel structure.
[background technology]
Aerator is a kind of oxygen replenishing equipment that is widely adopted in sewage disposal.Especially adopt in the process of biological treatment in sewage disposal, bacterium and mushroom microorganism and the microfaunas such as protozoon, metazoan are attached to growth and breeding on filtrate or some carrier, need to consume a large amount of oxygen, in the waste water of aeration aerating, waste water is with certain flow velocity filler of flowing through.Organic pollutant in waste water is converted into H by the microorganism absorption degradation on microbial film
2O, CO
2, NH
3And microbial cell material, make it form membranaceous biological clay---microbial film in the above, continued growth again after biofilm detachment precipitation, the renewal that constantly comes off of aging microbial film.So constantly circulate and make sewage be able to treatment and purification.No matter but be trade effluent or sanitary sewage, oxygen content does not seldom even almost have oxygen, therefore, must use aerator to biomembrane reaction pond oxygenation.
Aerator has many types, and commonly used have diaphragm type aerator, dynamic aeration device, ceramic micropore aerator, sintered type aerator etc.The chief drawback is that pore is large for these aerators, and formed bubble is thicker, and just more than 5mm, though tolerance is large, because bubble is thick, lift velocity is fast for the bubble diameter when generally giving vent to anger, in water the residence time short, coefficient of oxygen utilization is relatively low.In addition, the production well of these aerators is open, and during intermittence, due to return of waste water, the mud impurity in waste water stops up pore under the pressure-acting of recirculation water aerator in work.The diaphragm type aerator is because of the elastic contribution of rubber, and the return of waste water pore can be closed in resilience, but the pore of diaphragm type aerator die-cut the forming that be cutter, be the long linear of 8mm, diaphragm is heaved by air pressure during aeration, the linear pore drum outside aeration that breaks, because of opening larger, stop the supple of gas or steam when refluxing, still there is the hidden danger of stopping up, and because of wire opening, stress concentration, rubber diaphragm is easily torn, and affects work-ing life.
Therefore, if can develop micro-bubble, self-closing, can really realize not stopping up, the life-span be long, and the aerator of new generation that can not tear is so for promoting the development of microbial film wastewater processing technology and application that very important meaning is arranged.
