Abstract
The utility model provides a biological reactor for treating amino nitrogen waste water, namely a biological reactor with the nitration and anti-nitration processes reacting simultaneously. The utility model comprises an air inlet device, an in-out water valve and a pipeline. When the utility model is in operation, the way of air entering from the middle part is adopted to ensure that the upper part of the reactor is an aerobic zone to generate nitration; the lower part of the reactor is an anoxic zone or an anaerobic zone to generate anti-nitration. The reactor is provided inside with granular waste rubber to reduce the time of reaction. The utility model has reasonable structure and easy manipulation. In the same reactor, water enters from the upper part of the reactor and comes out from the lower part of the reactor through a medium, and the nitration and anti-nitration processes undergo simultaneously and continuously.
Description
Technical field
The utility model belongs to wastewater processing technology, particularly a kind of processing ammonia nitrogen waste water bio-reactor.
Background technology
In wastewater treatment, the removal of ammonia nitrogen waste water is by " nitrated-denitrification " process, and the ammonia nitrogen class toxic substance that makes in the waste water to be contained changes into nontoxic nitrogen and discharges from water body.Usually, nitration reaction and anti-nitration reaction are that segmentation is carried out.Be that nitration reaction is mainly carried out in aerobe reactor, anti-nitration reaction then carries out [Hong W.at el 1998, water research, Vol.33, No.4,961-970] in anoxic or anaerobic reactor.Current, also have many scholar's research in same reactor, to carry out nitrification and denitrification reaction simultaneously, currently used method is a segmented mode, promptly in same reactor, the act charitably nitration reaction of oxygen of advanced person, keep certain hour after, stop into oxygen; After stopping certain hour, carry out anoxic or anaerobic anti-nitration reaction again, strict control the two and the middle needed time of stop process [Hyungseok Yoo et al 1998, waterresearch, Vol.33, No.1,145-154 and Takao Yamagishi at el 2001, water research, Vol.35, No.13,3089-3096].Though this method is carried out the nitrification and denitrification reaction in same reactor, it comes down to a kind of batch reactor.In order to guarantee treatment effect, in production reality, must strict controlling reaction time.
Summary of the invention
The utility model is exactly develop at the deficiency of above-mentioned situation a kind of simple and carries out the bio-reactor that ammonia nitrogen waste water is handled continuously in same reactor.
The utility model is made of institutes such as bio-reactor, Inlet and outlet water valve and pipelines, described bio-reactor is equipped with the container of particle media, the top of described bio-reactor is provided with the inlet distribution device, and the inlet of inlet distribution device is connected with the water inlet pipe of bringing water valve into; The middle part that is positioned at bio-reactor is provided with diffuser, and the one end connects the inlet pipe that has intake valve, and diffuser is divided into two zones up and down with reactor, and top is aerobic zone, and nitration reaction takes place; The bottom is anaerobism or oxygen-starved area, carries out anti-nitration reaction.The porous plate that is provided with the uniform distribution drain cap in the bottom of bio-reactor is supporting particle media, and particle media adopts waste old, and it can accelerate the speed of nitration reaction and anti-nitration reaction, shortens the treatment time of nitrogen-containing wastewater; The bottom of bio-reactor is provided with rising pipe that has outlet valve and the water shoot that has water discharge valve that is connected with front position.
According to the continuous bio-reactor of processing ammonia nitrogen waste water that the utility model is made, not only simple in structure, easy to operate, make, running cost is low, and possess following characteristics:
1. middle air inlet is divided into two different reaction conditionss with reactor, and being reflected in the same reactor of two kinds of different conditions of assurance carried out continuously, reduced by a reactor, promptly reduced initial cost.
2. be added with the waste old medium, quickened speed of response, shortened the treatment time of nitrogen-containing wastewater, reduced working cost.
3. the processing to ammonia nitrogen waste water guarantees to carry out continuously.
4. reliable, the safety of operational management can guarantee the effluent quality after ammonia nitrogen waste water is handled.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in Figure 1, reactor 13 is the container of upper shed, in particulate state waste old 10 is housed.Through water intaking valve 5, the right-angled intersection pipe 12 of intaking from reactor top flows into the container, leaves the space between cross pipe and the rubber by water inlet pipe 1 in water inlet; The middle part of reactor is equipped with the diffuser 11 that is cross type, and its cross end is connected with the inlet pipe 2 of bringing air valve 6 into, between right-angled intersection pipe 12 and diffuser 11 nitration reaction takes place.In the bottom of reactor 13, a porous plate 14 is installed, porous plate is provided with uniform drain cap 9, and particulate state waste old 10 is supported by porous plate 14; Anti-nitration reaction takes place between diffuser 11 and porous plate 14.The bottom of reactor is provided with the rising pipe 3 of outlet valve 7 and the water shoot that has water discharge valve 84 that is connected with front position.Water outlet is flowed out through the rising pipe 3 of outlet valve 7, and draining is discharged through the water shoot 4 of water discharge valve 8.
