Background technology
Anammox is a kind of Process of Biological Nitrogen Removal, can under anaerobic take ammonia as electron donor nitrite be reduced to nitrogen, removes when realizing two kinds of nitrogen pollutants.The advantages such as than the traditional biological denitrification process, it is good that Anammox has a denitrification effect, need not oxygen and add organic carbon source, and excess sludge production is few, and running cost is low have good prospects for commercial application.Comparatively anaerobic ammonia oxidation reactor (as: upflow anaerobic sludge blanket reactor, anaerobic fluidized bed reactor, anaerobic filter etc.) commonly used has some defectives usually, as: because water inlet matter distribution inequality causes reactor bottom local host excessive concentration, anaerobic ammonia oxidizing bacteria is produced local the inhibition, and middle and high matrix undersupply of reactor, sludge activity is not enough; The reactor bottom shearing force is too high, is unfavorable for the formation of granule sludge, mud-water separation weak effect, the easy loss of mud etc.The existence of factor like that all is unfavorable for the performance of anaerobic ammonia oxidation bioreactor denitrogenation potential, becomes a bottleneck of efficient anaerobic ammoxidation reactor industrial applications.
Summary of the invention
In order to solve in traditional anaerobic ammonia oxidation reactor water inlet matter distribution inequality, the local inhibition of anaerobic ammonia oxidizing bacteria, the reactor the easily problems such as losss of high section matrix undersupply, sludge activity deficiency and mud-water separation weak effect, mud, the present invention proposes and a kind ofly reduce local hydraulic shearing force that reactor bottom mud bears, avoid reactor bottom the uniform-distributed feeding flow lifting type anaerobic ammonia oxidation reactor of the matrix supply in high section zone in local host inhibition, the enhanced reactor to occur.
The technical solution used in the present invention is:
A kind of uniform-distributed feeding flow lifting type anaerobic ammonia oxidation reactor is characterized in that: comprise device body, described device body upper end arranges on the sidewall of sludge settling district, lower end several water-ins is set, and described water-in links to each other with inlet chest by peristaltic pump; Triphase separator is installed at top, described sludge settling district, and the top of described triphase separator arranges the venting port that is communicated with water-sealed drainage bottle; The top in described sludge settling district is provided with the overflow weir of water outlet; Described water outlet is connected with water tank.
Further, the aspect ratio of described device body is 6 ~ 8:1, and the bottom convergent is cone, and the level inclination α of described cone is 30 ~ 45 degree.
Further, described water-in is provided with 4 ~ 6, evenly is arranged in 5 ~ 7 Along ent positions of device body height.
Further, described water-in is equipped with under meter and water intaking valve.
