Description

MBBR reactor

Technical field

The invention belongs to environmental technology field, particularly belong to water treatment field, it relates to MBBR reactor, and it is a kind of shifting Movable bed biofilm reactor, it is applicable to the working site of multiple different working condition.

Background technology

In water body, the too high meeting of ammonia-nitrogen content causes Water Eutrophication, causes some algae excessive propagation in water body, other Biological growth is affected, thus destroys aquatic ecosystem, causes water quality deterioration and has influence on its use function.Biological de- Nitrogen technology is the most most widely used denitrogenation of waste water technology.Although nitration processes can be nitrate mineralized nitrogen, eliminate ammonia nitrogen Pollution, but can not thoroughly eliminate polluted by nitrogen.Although and denitrification process can eradicate the pollution of nitrogen, but can not directly remove ammonia Nitrogen.Therefore, traditional biological denitrification process is generally made up of nitration processes and denitrification process.Due to the flora difference participated in and work Skill operational factor is different, and two processes of nitrification and denitrification need to carry out in the reactor of two isolation, or in the time or Spatially cause in the same reactor of alternately anoxia and aerobic environment and carry out, accordingly, it would be desirable to additional loop carry out mud and Nitrification liquid backflow or increase time, spatial sequence control system, add power consumption and operating cost, bring to practical operation Inconvenience.Additionally, nitrifying bacteria community growth rate is slow and is difficult to maintain higher biological concentration, cause the total waterpower of traditional active sludge system The time of staying is longer, and organic loading is relatively low, and Organic substance treatment effeciency is the highest, adds capital expenditure and operating cost.

The MBBR (MBBR) being used widely recently is direct close to the floating stuffing of water with proportion It is added in Aeration tank the active carrier as microorganism, relies on the aeration in Aeration tank and the castering action of current to be in stream Change state, when microorganism is attached on carrier, floating carrier in reactor along with mixed liquor convolution inverting action and from By moving, thus reach the purpose of sewage disposal.Activated sludge process and the biomembrance process phase of apposition growth as suspension growth In conjunction with a kind of technique, current MBBR reactor has both advantages concurrently, but there is also that filler easily runs off, filler easily exists Outlet piles up problems such as causing filler distribution uneven.

Additionally, due to water process aspect key point is water inlet, air inlet, water body flow to and with the way of contact of microorganism, water In time of staying etc., MBBR of the prior art (MBBR) there is also following defect: (1) existing moving bed Biofilm reactor can not water inlet be arranged uniformly and the flow direction of water does not has special guiding；(2) existing moving-bed biofilm is anti- Answer device to be not specified by the trend of gas, only play the effect of aeration.And the outer row of gas direct water outlet face Xiangshui County； (3) there is the phenomenon of current channel in existing MBBR, owing to not having channeling direction to cause part water body to stop Deficiency of time treatment effect is poor, and the part water body time of staying is long results in a large amount of dead mud phenomenon；(4) existing moving bed is raw Thing membrane reactor sufficiently sinks space to filler, it is impossible to allow filler sufficiently and waste water, thus affects biological living Property and treatment effect；(5) in existing MBBR, filler can not cause part to be filled out at reactor internal circulation flow Material is chronically at dead angle state.

Based on current this situation, it is badly in need of developing a kind of processing equipment that can be more flexible and efficient.

Summary of the invention

In order to solve above-mentioned technical problem, the present invention provides a kind of MBBR (MBBR reactor), its The ultimate principle using biomembrance process carries out the technology of sewage disposal, and takes full advantage of the feature of activated sludge process, gram Traditional activated sludge process and the defect of fixed type biological embrane method are taken.
