Invention 92237964 discloses a kind of improved biological contact oxidation pond waste disposal plant, it is characterized in that it is little than sewage that the biofilm carrier filler adopts proportion, the multiaspect hollow ball that specific surface area is big, this filling ball is limited in the sewage by a bigger guard, and filler the periphery or in the filler agitator is set, to promote biomembranous renewal.
In bio-contact oxidation dirt, wastewater processing technology, filler and aerating system are the cores, and it directly has influence on oxygenation capacity, treatment effect, initial cost and power consumption.
At present, domestic in the bio-contact oxidation treatment technology employed filler great majority be soft cellulose filler, medium-soft fibrous packing, combined stuffing, floating stuffing.Though the soft cellulose filler specific surface area is big, and is in light weight, physics, stable chemical performance, shortcoming are to be easy to caking, and are easy to be formed centrally in caking anaerobic zone.Though semi soft packing has good gas distribution, distribution performance, shortcoming is that specific surface area is little, microbial film insufficient total amount in the actual moving process, and smooth surface biofilm difficulty, microbial film easily comes off.Though the combined stuffing biofilm is easier to, hole is variable, and shortcoming is that soft vinylon fibre proportion is 1.02, overweights water, and sagging in water, strand is difficult to loose unfolding, and easily conglomeration causes that the actual specific surface-area can descend significantly in application.In production run, aqueous vapor replaces disturbance during owing to oxygenic aeration, and the soft fiber material is too soft, and the hole mutability is too big, and the contact probability of water, gas, film reduces relatively, and oxygen-transfer efficiency is low.Between adding sheet and sheet being connected certain spacing is arranged, short stream situation is more serious.Though the proportion after the floating stuffing biofilm approaches water, freely be suspended in the water body, make microorganism and pollution substance that more touch opportunity be arranged, make in the water body oxygen distribution even, shortcoming is to need cage shape net to collect, in can not directly applying to, heavy construction.
The installation of above various types of filler except that floating stuffing, but is adopted movable Steel Bracket, fixedly Steel Bracket and overall plastic lift frame mostly.But that they exist in varying degrees is not corrosion-resistant, Heavy Weight and transportation inconvenience, problem such as involve great expense.
Domestic in the bio-contact oxidation treatment technology employed aerator mainly contain big or middle bubble aeration device and micro-hole aerator two big classes.Big or middle bubble aeration device commonly used in the engineering has: steel perforated pipe aerating regulation device, perforation air diffusion aerator, dicyclo umbrella shape aerator, fixedly spiral aerator, basin type aerator, dynamic aeration device.Such aerator belongs to the imporosity diffusion structure, though be difficult for stopping up, drag losses is less, and required air quantity is many, and bubble is big, and gas-water contact area is little, and the utilization ratio of oxygen is low, the energy consumption height.Micro-hole aerator commonly used in the engineering has: micro-hole aerator, bell-jar micro-hole aerator, flat micro-hole aerator in the reticular membrane, can open middle micro-hole aerator, the bar-shaped micro-hole aerator of polyethylene.Such aerator genus polyporus diffusion structure is though the utilization ratio height of oxygen very easily stops up.After taking place, stopping state will cause that the diaphragm inside and outside differential pressure increases, and causes the cylindrical void stress concentration, thereby cylindrical void is torn, diaphragm breakage.In addition, the bubble that micro-pore aeration is produced when aeration is a microbubble, water body is stirred deficiency, thereby be unfavorable for the biomembranous renewal of filling surface.And microbubble not only usually show when bumping with filler in the process that rises can be broken, tend to the polymeric phenomenon on the contrary, reduced the utilization ratio of oxygen.Moreover micro-pore aeration is always worked under the state in one, can not wash away old dead microbial film with atm number.
In the bio-contact oxidation treatment technology, two conditions are satisfied in distributing rationally of filler and aerating system, that is: want synchronously the work-ing life of filler and aerating system, and be difficult for stopping up; Filler will have good cutting action to bubble, to improve the utilization ratio of oxygen.In engineering in the past, the configuration of above-mentioned filler and above-mentioned aerating system all can not well be satisfied these two conditions and hindered the development of bio-contact oxidation treatment technology.
