Description
Technical field
The utility model is the sewage disposal technology in the environmental engineering subject, is the modern technique that is applied to middle-size and small-size sanitary sewage and Industrial Wastewater Treatment.
Background technology
Biological treatment is the main method of sewage disposal at present, can be divided into activated sludge process and biomembrance process.Activated sludge process is owing to technology maturation, and equipment is reliable, is able to widespread use at large-scale wastewater treatment plant, but in the problem that has fluctuation of service aspect the middle-size and small-size sewage disposal, and energy consumption is higher.The principal mode of biomembrance process has: biological filter, blodisc and biological contact oxidation process etc. are used for middle-size and small-size sewage disposal more.Blodisc originates from preceding Germany, because characteristics such as processing efficiency height, maintenance management are convenient, working cost is low, particularly uses in the small-sized sanitary sewage disposal of country such as Britain and Switzerland comparatively general in Europe.Traditional blodisc divides forms such as single shaft single-stage, single-shaft multi-stage and multiaxis be multistage, except that the denitrogenation of microbial film itself, does not generally consider the denitrogenation measure on the technology, and nitric efficiency is lower.Idol aerobic+anaerobism+aerobic the combination that has denitrification process also to need promptly minimumly will be arranged to three forms, and need add low molecule organic matter such as methyl alcohol at anaerobic zone, and technology is comparatively complicated, and energy consumption is higher.
Therefore invent a kind of single-shaft multi-stage blodisc, can rely on the rotation of rotating disk itself to promote the aerobic zone sewage backflow automatically handles to front denitrogenation district, under the situation that does not increase energy consumption substantially, improve the technology nitric efficiency, guarantee the water outlet effect, centering small-scale sewage denitrogenation processing has very big adaptability.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of nitric efficiency that can improve blodisc technology, can cut down the consumption of energy again and the combined self-refluxing denitrogenating biological turntable device of equipment complexity.
Technical scheme: combined self-refluxing denitrogenating biological turntable device of the present utility model, the left side in framework is a denitrification tank, the right is a reaction tank, rotating shaft is horizontally placed on the centre of reaction tank, one end of rotating shaft is connected with electric motor, be respectively equipped with first step blodisc in the centre of rotating shaft, second stage blodisc, third stage blodisc, at first step blodisc, second stage blodisc, be provided with dividing plate between the third stage blodisc, the outside at third stage blodisc is provided with riser tube, side over against riser tube in reaction tank is provided with backflash, the water side of backflash connects return line, and return line connects recycle control valve; Water inlet pipe, shore pipe are communicated with denitrification tank respectively with outside, and the rising pipe connected reaction pond is with outside, communicating pipe connected reaction pond and denitrification tank; Be provided with the denitrification tank filler in the bottom of denitrification tank.On the periphery of first step blodisc, second stage blodisc, third stage blodisc, be provided with the plate that pumps up water, be full of how empty Ball-type packing in the inside of first step blodisc, second stage blodisc, third stage blodisc.Riser tube is fixed on the carousel frame by the riser tube fixing hoop, riser tube outer end open-ended, and the other end is opened a spilehole.
The utility model is a kind of technology that adopts the combined self-refluxing denitrogenating biological turntable device to replace the traditional biological rotating disk.This blodisc is by adopting new packing built-up type disc, and specific surface area and capacity utilization improve greatly.Hang riser tube on the rotating disk disc endways, the sewage of by riser tube aerobic zone being finished nitration reaction in the dial rotation process rises to certain altitude, pours in the backflash, and the denitrification tank or the first step blodisc that are back to the front certainly carry out denitrogenation processing.Energy consumption equipment such as reflux pump are not set separately, are not increasing substantially under the situation of energy consumption, make blodisc have the efficient denitrification function, remedy the deficiency of traditional biological rotating disk aspect denitrogenation.
Technique effect: the utlity model has following characteristics:
1, the utility model can significantly improve the blodisc nitric efficiency.
2, finish from reflux course by the riser tube castering action in the dial rotation process, do not need special refluxing units such as reflux pump.Not increasing energy consumption substantially and adding under the condition of several pipe fittings, nitric efficiency is improved, maintenance management is convenient.
3, this technical combinations mode flexible and convenient, maintenance management is convenient, and energy consumption is economized.
